Effect of chronic hypoxia on alpha-1 adrenoceptor-mediated inositol 1,4,5-trisphosphate signaling in ovine uterine artery. (1/5911)

The present study examined the effect of chronic hypoxia on coupling efficiency of alpha-1 adrenoceptors to inositol 1,4,5-trisphosphate (InsP3) signaling in ovine uterine artery. Chronic hypoxia did not change the time course of InsP3 formation, but significantly decreased the potency (pD2: 6.17 +/- 0.09 --> 5.26 +/- 0.12) and the maximal response (220.7 +/- 21.7 --> 147.7 +/- 15.3 pmol/mg protein) of norepinephrine-induced InsP3 synthesis. The coupling efficiency of alpha-1 adrenoceptors to InsP3 synthesis (picomoles InsP3 per femtomoles receptor) was decreased 45% by chronic hypoxia. In addition, simultaneous measurement of norepinephrine-induced contractions and InsP3 synthesis indicated that for a given amount of InsP3 generated, the contractile force of the uterine artery was significantly less in chronically hypoxic than in control tissues (0. 27 +/- 0.01 versus 0.35 +/- 0.02 g tension/pmol InsP3). InsP3 receptors were characterized using radioligand binding techniques. Although the density of InsP3 receptors was not changed by chronic hypoxia (Bmax: 325 +/- 35 --> 378 +/- 18 fmol/mg protein), the dissociation constant (Kd) of InsP3 to its receptors was significantly increased (Kd: 5.20 +/- 0.40 --> 7.81 +/- 0.34 nM). Analysis of InsP3 receptor occupancy-tension development relationship indicated no difference in intrinsic ability of the InsP3-receptor complex in eliciting contractions between the control and hypoxic tissues. Our results suggest that chronic hypoxia attenuates coupling efficiency of alpha-1 adrenoceptors to InsP3 synthesis in the uterine artery. In addition, the tissue contractile sensitivity to InsP3 is reduced, which is mediated predominantly by a decrease in InsP3 binding affinity to InsP3 receptors.  (+info)

In oculo transplants of myometrium from postpartum guinea pigs fail to support sympathetic reinnervation. (2/5911)

Sympathetic nerves to the enlarged fetus-containing region of the uterus undergo degenerative changes during late pregnancy and show slow regrowth after parturition. It is not known whether this unusual response of sympathetic nerves to smooth muscle hypertrophy is due to the sensitivity of short adrenergic neurons to hormonal changes, or whether the nerves respond to changes in the neurotrophic capacity of the target. We have investigated this question using in oculo transplantation. Small pieces of myometrium from the uterine horn of virgin guinea pigs, or from the region previously occupied by the placenta and fetus in postpartum guinea pigs, were transplanted into the anterior eye chamber. After 3 wk in oculo, the pattern of reinnervation of the transplants was assessed on whole mount stretch preparations stained for tyrosine hydroxylase. The histology of the transplants was examined in toluidine blue-stained semithin sections. Myometrial transplants from virgin donors and uterine artery transplants from both virgin and postpartum donors became organotypically reinnervated by sympathetic fibres from the host iris. In contrast, sympathetic nerves did not reinnervate myometrial transplants from postpartum donors, although they approached the transplants and became distributed in the surrounding connective tissue. All transplanted tissues showed a normal histological appearance. Both the myometrium and uterine artery from postpartum donors retained a hypertrophic appearance after 3 wk in oculo. We interpret these results to indicate that the degeneration of sympathetic nerves in late pregnancy, as well as their slow regrowth to the uterus after delivery, may be due to changes in uterine smooth muscle rather than a particular sensitivity of short adrenergic neurons to hormonal changes.  (+info)

Facilitation and depression of ATP and noradrenaline release from sympathetic nerves of rat tail artery. (3/5911)

1. Excitatory junction currents (EJCs) were used to measure ATP release; noradrenaline (NA) oxidation currents and fractional overflow of labelled NA, [3H]NA, were used to monitor the release of endogenous and exogenous NA, respectively, from post-ganglionic sympathetic nerves of rat tail artery. 2. During nerve stimulation with 100 pulses at 5-20 Hz the EJCs initially grew in size (maximally by 23 %, at 2-10 Hz), and then depressed, maximally by 68 % at 20 Hz. 3. The peak amplitude of NA oxidation currents in response to nerve stimulation with 100 pulses at 2-20 Hz grew in size with frequency, while the area was independent of frequency and roughly constant. 4. The size of the NA oxidation currents evoked by nerve stimulation with 4-100 pulses at 20 Hz grew linearly with train length between pulses 4-16. Between pulses 20-100 there was a train length-dependent depression of the signal. 5. Fractional overflow of [3H]NA in response to nerve stimulation with 5-100 pulses at 20 Hz behaved similarly to the EJCs. It initially grew roughly linearly between pulses 5-25, and then showed a dramatic depression similar to that of the EJCs. 6. The alpha2-adrenoceptor antagonists rauwolscine and yohimbine increased the overflow of [3H]NA and the amplitude of NA oxidation currents, but not that of the EJCs. 7. It is concluded that during high-frequency stimulation (i) the release of ATP and NA is first briefly facilitated then markedly depressed, (ii) facilitation and depression of the two transmitters are similar in magnitude and time course, and (iii) alpha2-adrenoceptor antagonists differentially modify EJCs and the NA signals. The results obtained in the absence of drugs are compatible with the hypothesis that ATP and NA are released in parallel, while the effects of alpha2-adrenoceptor antagonists seem to suggest dissociated release.  (+info)

Effects of Ca2+ concentration and Ca2+ channel blockers on noradrenaline release and purinergic neuroeffector transmission in rat tail artery. (4/5911)

1. The effects of Ca2+ concentration and Ca2+ channel blockers on noradrenaline (NA) and adenosine 5'-triphosphate (ATP) release from postganglionic sympathetic nerves have been investigated in rat tail arteries in vitro. Intracellularly recorded excitatory junction potentials ( were used as a measure of ATP release and continuous amperometry was used to measure NA release. 2. Varying the extracellular Ca2+ concentration similarly affected the amplitudes of and NA-induced oxidation currents evoked by trains of ten stimuli at 1 Hz. 3. The N-type Ca2+ blocker, omega-conotoxin GVIA (omega-CTX GVIA, 0.1 microM) reduced the amplitudes of both (evoked by trains of ten stimuli at 1 Hz) and NA-induced oxidation currents (evoked by trains of ten stimuli at 1 Hz and 50 stimuli at 10 Hz) by about 90%. 4. The omega-CTX GVIA resistant and NA-induced oxidation currents evoked by trains of 50 stimuli at 10 Hz were abolished by the non-selective Ca2+ channel blocker, Cd2+ (0.1 mM), and were reduced by omega-conotoxin MVIIC (0.5 microM) and omega-agatoxin IVA (40 nM). 5. Nifedipine (10 microm) had no inhibitory effect on omega-CTX GVIA resistant and NA-induced oxidation currents. 6. Thus both varying Ca2+ concentration and applying Ca2+ channel blockers results in similar effects on NA and ATP release from postganglionic sympathetic nerves. These findings are consistent with the hypothesis that NA and ATP are co-released together from the sympathetic nerve terminals.  (+info)

Impact of vascular adaptation to chronic aortic regurgitation on left ventricular performance. (5/5911)

BACKGROUND: This investigation was designed to test the hypothesis that vascular adaptation occurs in patients with chronic aortic regurgitation to maintain left ventricular (LV) performance. METHODS AND RESULTS: Forty-five patients with chronic aortic regurgitation (mean age 50+/-14 years) were studied using a micromanometer LV catheter to obtain LV pressures and radionuclide ventriculography to obtain LV volumes during multiple loading conditions and right atrial pacing. These 45 patients were subgrouped according to their LV contractility (Ees) and ejection fraction values. Group I consisted of 24 patients with a normal Ees. Group IIa consisted of 10 patients with impaired Ees values (Ees <1.00 mm Hg/mL) but normal LV ejection fractions; Group IIb consisted of 11 patients with impaired contractility and reduced LV ejection fractions. The left ventricular-arterial coupling ratio, Ees/Ea, where Ea was calculated by dividing the LV end-systolic pressure by LV stroke volume, averaged 1.60+/-0.91 in Group I. It decreased to 0.91+/-0.27 in Group IIa (P<0.05 versus Group I), and it decreased further in Group IIb to 0.43+/-0.24 (P<0.001 versus Groups I and IIa). The LV ejection fractions were inversely related to the Ea values in both the normal and impaired contractility groups (r=-0.48, P<0.05 and r=-0.56, P<0.01, respectively), although the slopes of these relationships differed (P<0.05). The average LV work was maximal in Group IIa when the left ventricular-arterial coupling ratio was near 1.0 because of a significant decrease in total arterial elastance (P<0.01 versus Group I). In contrast, the decrease in the left ventricular-arterial coupling ratio in Group IIb was caused by an increase in total arterial elastance, effectively double loading the LV, contributing to a decrease in LV pump efficiency (P<0.01 versus Group IIa and P<0.001 versus Group I). CONCLUSIONS: Vascular adaptation may be heterogeneous in patients with chronic aortic regurgitation. In some, total arterial elastance decreases to maximize LV work and maintain LV performance, whereas in others, it increases, thereby double loading the LV, contributing to afterload excess and a deterioration in LV performance that is most prominent in those with impaired contractility.  (+info)

BDNF is a target-derived survival factor for arterial baroreceptor and chemoafferent primary sensory neurons. (6/5911)

Brain-derived neurotrophic factor (BDNF) supports survival of 50% of visceral afferent neurons in the nodose/petrosal sensory ganglion complex (NPG; Ernfors et al., 1994a; Jones et al., 1994; Conover et al., 1995; Liu et al., 1995; Erickson et al., 1996), including arterial chemoafferents that innervate the carotid body and are required for development of normal breathing (Erickson et al., 1996). However, the relationship between BDNF dependence of visceral afferents and the location and timing of BDNF expression in visceral tissues is unknown. The present study demonstrates that BDNF mRNA and protein are transiently expressed in NPG targets in the fetal cardiac outflow tract, including baroreceptor regions in the aortic arch, carotid sinus, and right subclavian artery, as well as in the carotid body. The period of BDNF expression corresponds to the onset of sensory innervation and to the time at which fetal NPG neurons are BDNF-dependent in vitro. Moreover, baroreceptor innervation is absent in newborn mice lacking BDNF. In addition to vascular targets, vascular afferents themselves express high levels of BDNF, both during and after the time they are BDNF-dependent. However, endogenous BDNF supports survival of fetal NPG neurons in vitro only under depolarizing conditions. Together, these data indicate two roles for BDNF during vascular afferent pathway development; initially, as a target-derived survival factor, and subsequently, as a signaling molecule produced by the afferents themselves. Furthermore, the fact that BDNF is required for survival of functionally distinct populations of vascular afferents demonstrates that trophic requirements of NPG neurons are not modality-specific but may instead be associated with innervation of particular organ systems.  (+info)

Alteration of endothelium-dependent hyperpolarizations in porcine coronary arteries with regenerated endothelium. (7/5911)

The present study was designed to test the ability of regenerated endothelium to evoke endothelium-dependent hyperpolarizations. Hyperpolarizations induced by serotonin and bradykinin were compared in isolated porcine coronary arteries with native or regenerated endothelium, 4 weeks after balloon endothelial denudation. The experiments were performed in the presence of inhibitors of nitric oxide synthase (Nomega-nitro-L-arginine) and cyclooxygenase (indomethacin). The transmembrane potential was measured using conventional glass microelectrodes. Smooth muscle cells from coronary arteries with regenerated endothelium were depolarized in comparison with control coronary arteries from the same hearts. Spontaneous membrane potential oscillations of small amplitude or spikes were observed in some of these arteries but never in arteries with native endothelium. In coronary arteries from control pigs, both serotonin and bradykinin induced concentration-dependent hyperpolarizations. In the presence of ketanserin, 10 micromol/L serotonin induced a transient hyperpolarization in control coronary arteries. Four weeks after balloon denudation, the response to serotonin was normal in arteries with native endothelium, but the hyperpolarization was significantly lower in coronary arteries with regenerated endothelium. In control arteries, the endothelium-dependent hyperpolarization obtained with bradykinin (30 nmol/L) was reproducible. Four weeks after balloon denudation, comparable hyperpolarizations were obtained in coronary arteries with native endothelium. By contrast, in arteries with regenerated endothelium, the hyperpolarization to bradykinin became voltage-dependent. In the most depolarized cells, the hyperpolarization to bradykinin was augmented. The changes in resting membrane potential and the alteration in endothelium-dependent hyperpolarizations observed in the coronary arteries with regenerated endothelium may contribute to the reduced response to serotonin and the unchanged relaxation to bradykinin described previously.  (+info)

Balloon-artery interactions during stent placement: a finite element analysis approach to pressure, compliance, and stent design as contributors to vascular injury. (8/5911)

Endovascular stents expand the arterial lumen more than balloon angioplasty and reduce rates of restenosis after coronary angioplasty in selected patients. Understanding the factors involved in vascular injury imposed during stent deployment may allow optimization of stent design and stent-placement protocols so as to limit vascular injury and perhaps reduce restenosis. Addressing the hypothesis that a previously undescribed mechanism of vascular injury during stent deployment is balloon-artery interaction, we have used finite element analysis to model how balloon-artery contact stress and area depend on stent-strut geometry, balloon compliance, and inflation pressure. We also examined superficial injury during deployment of stents of varied design in vivo and in a phantom model ex vivo to show that balloon-induced damage can be modulated by altering stent design. Our results show that higher inflation pressures, wider stent-strut openings, and more compliant balloon materials cause markedly larger surface-contact areas and contact stresses between stent struts. Appreciating that the contact stress and contact area are functions of placement pressure, stent geometry, and balloon compliance may help direct development of novel stent designs and stent-deployment protocols so as to minimize vascular injury during stenting and perhaps to optimize long-term outcomes.  (+info)

Vasodilatation in ischaemic human subcutaneous resistance arteries - Science Exchange Lets You Compare Quotes From Leading Service Providers.
Our results demonstrate that in vitro blockade of ACE is insufficient to prevent the contraction of human subcutaneous resistance arteries to Ang I. Because our preliminary experiments showed that this response is completely blocked by losartan, we assume that contraction to Ang I represents the effect of Ang II generated locally and acting on the Ang II type I receptor. Thus, treatment with an ACEI appears to be unable to prevent conversion of Ang I to Ang II in human resistance arteries. In the rabbit, in contrast, ACEI administration fully prevented Ang I-induced contraction.. Because ACE is identical to kininase II, the enzyme responsible for the degradation of kinins, it has been suggested that potentiation of BK may be partly responsible for the actions of ACEI. Thus, plasma kinin concentrations are increased in humans by quinapril, and ACEI-induced coronary artery vasodilation in dogs and humans has been shown to be mediated by BK.16 17 18 We investigated the effect of enalaprilat on the ...

BACKGROUND Creatine kinase (CK) is a main predictor of blood pressure, and this is thought to largely depend on high resistance artery contractility. We previously reported an association between vascular contractility and CK in normotensive pregnancy, but pregnancy is a strong CK inducer, and data on human hypertension are lacking. Therefore, we further explored CK-dependency of vascular contractility outside the context of pregnancy in normotensive and hypertensive women. METHODS AND RESULTS Nineteen consecutive women, mean age 42 years (SE 1.3), mean systolic/diastolic blood pressure respectively 142.6 (SE 5.9)/85.6 (3.4) mm Hg (9 hypertensive), donated an omental fat sample during abdominal surgery. We compared vasodilation after the specific CK inhibitor 2,4-dinitro-1-fluorobenzene (DNFB; 10-6 mol/l) to sodium nitroprusside (10-6 mol/l) in isolated resistance arteries using a wire myograph. Additionally, we assessed predictors of vasoconstrictive force. DNFB reduced vascular contractility ...
A distributing artery (or muscular artery) is a medium-sized artery that draws blood from an elastic artery and branch into resistance vessels including small arteries and arterioles. In contrast to the mechanism elastic arteries use to store energy generated by the hearts contraction, distributing arteries contain layers of smooth muscle. Under the microscope distributing arteries can be identified by their clearly defined internal elastic lamina. In constricted vessels the elastic lamina of distributing arteries appears thick and kinky. The elastic lamina is best visualized using Verhoeffs stain, but can be easily detected in specimens stained using other techniques as a well-defined negative staining region. Examples of distributing arteries include the radial artery and the splenic artery. Distributing arteries along with elastic arteries are common site for atherosclerosis.[citation needed] Norrander, J.M., Kirkpatrick C., Bauer, G.E., Porter, M.E., Marker, P.C., Linck, R.W., et al. ...
Definition of muscular artery in the Legal Dictionary - by Free online English dictionary and encyclopedia. What is muscular artery? Meaning of muscular artery as a legal term. What does muscular artery mean in law?
In hypertension and aging, central elastic arteries become stiffer and hence the central pulse pressure is augmented due to the increase in the pulse wave velocity and the early return of reflected waves to the heart from the periphery. Valuable information on arterial properties, such as stiffness, can be obtained from both central (aortic) and peripheral (radial) pressure wave forms. A feasibility study for the noninvasive estimation of arterial stiffness using pressure waves detected by a pneumatic cuff wrapped around the upper arm is presented. The propagation and reflection of arterial pressure waves (generated by the heart) in the central elastic arteries are simulated using a simplified water hammer acoustic model. Furthermore, a lumped parameter model is used to describe the transmission of the pressure waves from the brachial artery to the cuff external wall. By combining the two models, we were able to simulate the pressure contours in the brachial artery and illustrate how these ...
This study indicates that the aging process is associated with geometrical modifications of both large elastic and medium-sized muscular arteries, independent of blood pressure changes. Furthermore, enlargement of arterial diameter and thickening of the arterial wall have opposite effects on the functional parameters of these arteries. An alteration in elastic properties is observed for the carotid artery, but functional properties are preserved in the radial artery. Our results suggest that geometrical modifications associated with aging could be a means by which arteries try to maintain normal distensibility.. Several studies have described arterial changes associated with the aging process.15 16 Kawasaki et al17 studied the common carotid artery, abdominal aorta, femoral artery, and brachial artery in 39 subjects aged 6 to 81 years with an ultrasonic phase-locked echo-tracking system, and they observed a significant increase in the diameter of all arteries, with a reduction in the percentage ...

What is the difference between Elastic and Muscular Arteries? Elastic arteries have more elastin in tunica media; muscular arteries have lesser elastin amount
In this study, direct gene transfer was used to create somatic transgenic models to define gene function in arteries. We examined the pathogenesis of intimal thickening in porcine arteries after expression of PDGF B. Our findings show that recombinant PDGF B gene expression promotes rapid formation of an intima over a period of 3 weeks. The cellular composition of this intima is complex and changes with time. Within the first week after gene transfer, intimal smooth muscle cell proliferation is present. PDGF BB is expressed by these proliferating smooth muscle cells, suggesting that it can regulate cell proliferation in vivo. Intimal cell proliferation peaked at 1 week and declined 2 weeks after gene transfer. The total number of cells in the intima at 2 to 7 days could not be accounted for by proliferation alone, suggesting that migration of medial smooth muscle cells to the intima may contribute to the intimal lesion. These findings are consistent with previous observations in a different ...

Arteries form part of the circulatory system. They carry blood that is oxygenated after it has been pumped from the heart. Coronary arteries also aid the heart in pumping blood by sending oxygenated blood to the heart, allowing the muscles to function. Arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation (usually veins carry deoxygenated blood to the heart but the pulmonary veins carry oxygenated blood as well).[5] There are two types of unique arteries. The pulmonary artery carries blood from the heart to the lungs, where it receives oxygen. It is unique because the blood in it is not oxygenated, as it has not yet passed through the lungs. The other unique artery is the umbilical artery, which carries deoxygenated blood from a fetus to its mother.. Arteries have a blood pressure higher than other parts of the circulatory system. The pressure in arteries varies during the cardiac cycle. It is highest ...

I am a 79 year old retired Navy and Airline Pilot. One night I experienced a strange sensation that felt like a million needles in my chest. There was no back, arm or shoulder pain and I dismissed it for a while but the wife convinced me to take a ride to the local hospital ER. This was 3 years ago. When I arrived at the ER they immediately gave me a 81mg aspirin and hooked me to a EKG machine and took blood samples. After the EKG I was sent to the radiation dept for a chest X-ray. After all that, the staff trauma room doctor, a very intelligent and informed lady, came to talk to me. She said, Dave, we have run all the test and your EKG, blood gases, X-ray, blood pressure and pulse rate are normal. But I am afraid that you have a Coronary Artery Block and if I send you home you might die.

The mechanical properties of arteries are independent factors for cardiovascular disease and mortality, where genetics influence the structure of the arterial wall, which may result in change in arterial stiffness. The aims of this thesis were to study the mechanical properties of the popliteal artery (PA) in healthy subjects and the influence of angiotensin-converting enzyme (ACE) polymorphism and Fibrillin-1 (FBN1) polymorphism on large arteries. Further, the impact of FBN1 polymorphism on cardiovascular morbidity and mortality was investigated.. The PA is, after the abdominal aorta, the most common site of aneurysmal development. The PA was studied in healthy subject with ultrasound and the diameter increased and the distensibility decreased with age, with men having lower distensibility than women. This seems not to be the behavior of a true muscular artery but rather of a central elastic artery such as the ...

Atherosclerosis is the medical term used to describe clogged arteries or hardening of the arteries. It is a common form of heart disease, in which arteries become clogged or plugged with a fatty substance so that blood cannot easily flow and deliver oxygen rich blood. You might experience clogged arteries in the heart, brain, kidneys, intestines, arms or legs. Its important to know the symptoms of a clogged artery, especially if you have risk factors for getting one, so that you can get medical assistance as quickly as possible ...
Pain is one of the most common symptom of disease, and is thought to be an indication of an underlying pathology, but in some patients it is not possible to identify a pathophysiological mechanism or to find a well-known disease or pathology as the underlying condition. The evaluation of the patient with pain is frequently complex, because pain is a perception rather than a sensation. Now the diagnosis of pain intensity is based on patient s interpretation of a sensation, emotional response, and associated behavior. Newly discovered signal transduction pathway which uses nitric oxide (NO) to modulate the function of the vascular smooth muscle cells through mechanical wall shear stress (WSS) mechanism. WSS is a linear function of the blood flow rate and is inversely related to the third power of the vessel radius. Wall shear stress is influence smooth muscle tone changing arterial lumen. In turn, the changes in arterial lumen regulate the shear stress. Such the arterial lumen is controlled by ...

The staff in the ICU unit marveled at Dougs quick recovery and called him a walking miracle. An ultrasound showed that his left carotid artery was completely blocked, but other arteries in the area had grown and compensated for the blockage. Within six days, he was out of the hospital. In less than a month, he was back at work, but he felt well enough to go back sooner. The only issue he had was in learning to write his name again, but he totally recovered that ability.. Today, Doug cant help but get a little emotional when he talks about his stroke. He says he can see God in every detail of that day, starting with how he was at work because he originally wasnt scheduled to be. Also, he was where other people could see him when it started and working when the nurse was on site. If any of these things had been different, he might not have gotten the quick treatment he needed. Plus, he is amazed at how perfectly the other arteries have grown to compensate for the blockage and how he has been ...
Soften hardened arteries with this inexpensive nutrient As you may know, you have to do two things to avoid a heart attack. You have to keep your vascular system free of blood clots, especially the arteries around the heart. And you have to keep your arteries soft and supple. Hardened arteries, or atherosclerosis, occur when the arterial walls thicken because of a build-up of fatty materials. Many times, these two conditions go hand-in-hand. As the arterial walls thicken, they become more likely to clot.

Clogged arteries or atherosclerosis can lead to serious heart diseases. The function of the arteries is to transport oxygen and essential nutrients from heart to the rest of the body. Arteries can get clogged when due to high blood pressure cholesterol starts building up on the walls of the arteries. This can eventually lead to […]
Currently, no clinically available small (5 millimeter in diameter and smaller) vascular grafts can emulate the biological and physical properties of normal arteries. Implanted grafts of currently available materials fail because of clotting and stiffness as related to normal blood vessels. A small vessel prosthesis (artery graft) that better emulates normal arterial walls would greatly improve the treatment of both peripheral vascular disease and coronary artery disease, the researchers state in a summary of their research. This is one of the applications it suits perfectly since conventional fiber extrusion technology is incapable of making such a material i.e., one that can combine proteins and synthetic materials together to form a composite small- scale device with all the right kind of properties, Brown said ...
The person experiencing these signs may be under a different condition than heart diseases, but if in case it is a clogged artery symptom, immediate medical treatment should be done.. Plaque is the main cause of a clogged artery. When we eat fatty foods, some of the fats flow within our bloodstream. These may build up within the walls of our arteries. This does not happen quickly, but when this continues through the years, plaque may build up within the arterial walls, and when it is big enough, it causes obstruction in the blood flow, which means less blood and oxygen is delivered to the heart, causing it to be less functional.. The following are the most common signs of clogged arteries that should be observed carefully. Although these may indicate another condition, it is still best to respond to them quickly to prevent a stroke or heart attack.. Chest discomfort, which can be described as heaviness, tightness, pressure, burning, aching, or squeezing (this may last for several minutes and ...
The results of this research indicate that the plaque or blockages create around injuries in the arteries.. Now, injuries are formed mostly on places where physical stress on the artery is present and this is where we come to the thesis that certain substances called Lipoprotein(a) inhibitors should prevent and may even dissolve plaque that is present in the arteries. If the plaque is mostly made of this LP(a) LDL cholesterol and considering that this substance can and will attract even more LP(a), solution has been searched in this manner. Next, what if there are some substances that can be attracted to this sticky stuff and dissolve it?. Linus Pauling concluded that lysine, with the help of vitamin C can help the artery. This is just basics of his research but there is much more to it, this explanation is just simplified to be easily understandable. This article shows that with some quality research in to the source of some problems it is possible to understand the inner workings and see where ...
The heart is made mainly of special muscle. The heart pumps blood into blood vessels (arteries) which take the blood to every part of the body. The coronary arteries supply oxygen-rich blood to the heart If these arteries are narrowed or blocked, the heart does not get enough oxygen. This can cause angina or a heart attack. The blockage can be sudden […]. READ MORE ...

Mass deposition inside the artery wall may play a significant role in the development of the disease atherosclerosis. Locally elevated concentrations of LDL in the arterial wall are considered to be the initiator of atherosclerotic plaque formation. In this study, an attempt has been made to study initially the effect of fluid dynamic parameters on the disease and finally proposed a concept, from the idea of basic flow characteristics in constricted arteries, for the assessment of mass deposition in the arterial wall to some extent for rectangular as well as half circular stenosed models. Reynolds numbers are chosen as 100, 200, 300 and 400 and percentage of restrictions as 30%, 50%, 70% and 90% respectively. The governing Navier-Stokes and continuity equations are solved in the artery lumen with the commercial CFD code ANSYS 12.1. The pressure-velocity coupling equations are solved by SIMPLE (Semi-Implicit Method for Pressure-Linked Equations) algorithm. The studies on pressure drop at stenosis zone
I noticed what seems to be a flaw in my Kepler Bb humanoids 2 circulatory systems. That would be bleeding. Sure, the 2 hearts get more oxygen so an MI is less likely and if it does happen, the other healthy heart compensates so they are only considered to have heart disease if both hearts are damaged in some way.. But there is a big problem here with having the arteries right next to each other. If you have a pair of arteries that are the same size and right next to each other, the force from blood pressure on the walls will change. The force from the right side of the left artery will cause the right side of the right artery to have more force. Likewise, the force from the left side of the right artery will cause the left side of the left artery to have more force. Maybe not double but definitely more. Also, the right side of the left artery and the left side of the right artery will have less force. So overall, the force is going to be going outwards. This will cause asymmetric vasodilation ...

  • The fats that clog arteries apparently work in conjunction with air pollution particles to trigger the genes behind inflammation, which leads to increased lesions in the clogged arteries, and the potential for thrombi, and resultant heart attacks or strokes. (
  • Now we can recommend the Mediterranean diet as a preventive strategy for all disease of the cardiovascular system , including heart attacks, strokes and peripheral artery disease," Steinbaum said. (
  • Tainted air Long-term exposure to pollution may speed up hardening of the arteries contributing to heart attacks and strokes, say US researchers. (

  • A coronary artery bypass graft (CABG) is a surgical procedure used to treat coronary heart disease. (
  • While many cases of angina can be treated with medication, severe angina may require a coronary artery bypass graft to improve the blood supply to the heart. (
  • A coronary artery bypass graft may be recommended to reduce your chances of having a heart attack. (
  • A coronary artery bypass graft is carried out under general anaesthetic , which means you'll be unconscious during the operation. (
  • Most people will need to stay in hospital for at least 7 days after having a coronary artery bypass graft. (
  • As with all types of surgery, a coronary artery bypass graft carries a risk of complications. (
  • But a coronary artery bypass graft isn't a cure for coronary heart disease. (
  • A coronary angioplasty is the main alternative to a coronary artery bypass graft. (
  • It usually takes less time to recover from a coronary angioplasty than from a coronary artery bypass graft, but there's a higher chance that the procedure will need to be repeated. (
  • The length of time you'll have to wait to have a coronary artery bypass graft will vary from area to area. (
  • Another procedure is coronary artery bypass grafting (CABG). (
  • In addition to diet, exercise, medication therapy and coronary artery bypass graft (CABG) surgery there are a number of minimally invasive procedures that can restore blood flow through a blocked coronary artery. (

  • The extracranial carotid arteries include the common carotid artery, which originates in the chest, the external carotid artery, and the internal carotid artery to the base of the skull. (
  • Cholesterol and other fatty substances accumulate on the inner wall of the arteries. (
  • Doctors now know that CRP helps measure chronic inflammation and the overall health of your arteries. (
  • A research team showed that a nanotherapeutic medicine can halt the growth of artery plaque cells resulting in the fast reduction of the inflammation that may cause a heart attack, according to a study led by researchers from Icahn School of Medicine at Mount Sinai and published April 3 in Science Advances. (
  • Nanotherapeutically inhibiting local macrophage proliferation is possible and we can effectively apply it to treat inflammation inside arteries. (
  • Sometimes these stents are laced with slowly eluting medications to prevent inflammation and re-narrowing of the artery. (
  • There is also a rare condition known as spontaneous coronary artery dissection , in which the wall of one of the coronary arteries tears, causing severe pain. (
  • Now the new findings suggest the benefit extends to peripheral artery disease as well, said researcher Dr. Miguel Martinez-Gonzalez, a professor at the University of Navarra in Pamplona, Spain. (
  • In this study, older adults who maintained a Mediterranean diet were one-half to two-thirds less likely to develop painful peripheral artery disease, compared to those who tried to follow a low-fat regimen. (
  • Over five years, 89 participants developed painful peripheral artery disease. (
  • In the low-fat group, people developed peripheral artery disease at a rate of almost 0.5 percent per year. (
  • There are caveats, according to Martinez-Gonzalez's team -- one being the fairly small number of peripheral artery disease cases in the study. (
  • Its origin is at the lateral margin of the first rib, before which it is called the subclavian artery. (
  • The lateral sacral arteries are among the arteries of the lower back. (
  • These arteries traverse the sacrum's lateral border. (
  • Use these social-bookmarking links to share Air pollution may harden arteries . (
  • Over time, plaque can thicken and harden inside your arteries, blocking the flow of blood to your heart. (
  • When a d-transposition occurs, the blood pathway is impaired because the two arteries are connecting to the wrong chambers in the heart. (
  • This vessel or graft is sewn above and below the diseased artery so that blood flows through the new vessel or graft. (
  • The section of vein or man-made blood vessel graft is sewn onto both the femoral and popliteal arteries so that blood can travel through the new graft vessel and around the narrowed or blocked area. (
  • When people touch samples of Salubria in its vascular graft (artery replacement) form, they describe it as noodle-like or similar to calamari (squid)," Ku said. (

  • Renal artery stenosis is a condition in which the arteries supplying your kidneys become clogged. (
  • Therefore, any disorder or disease of the coronary arteries can have a serious impact on health, possibly leading to angina , a heart attack , and even death. (
  • Angina can happen when too much plaque builds up inside arteries, causing them to narrow. (
  • Nitrates can be used to treat angina, a common complication of coronary artery disease. (
  • As the disease progresses, chest pain (angina pectoris) may develop during periods of physical activity or emotional stress, because the narrowed arteries cannot supply the heart with the increased amount of blood and oxygen necessary at those times. (
  • According to the Mayo Clinic, clogged heart arteries can lead to angina (chest pain), because your heart does not receive enough blood flow. (
