Because the baroreceptors are tonically active, the baroreflex can compensate rapidly for both increases and decreases in blood pressure.
Single-chain polypeptides of about 65 amino acids (7 kDa) from LEECHES that have a neutral hydrophobic N terminus, an acidic hydrophilic C terminus, and a compact, hydrophobic core region. Recombinant hirudins lack tyr-63 sulfation and are referred to as 'desulfato-hirudins'. They form a stable non-covalent complex with ALPHA-THROMBIN, thereby abolishing its ability to cleave FIBRINOGEN.
Any pathological condition where fibrous connective tissue invades any organ, usually as a consequence of inflammation or other injury.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
The force that opposes the flow of BLOOD through a vascular bed. It is equal to the difference in BLOOD PRESSURE across the vascular bed divided by the CARDIAC OUTPUT.

The small mass of modified cardiac muscle fibers located at the junction of the superior vena cava (VENA CAVA, SUPERIOR) and right atrium. Contraction impulses probably start in this node, spread over the atrium (HEART ATRIUM) and are then transmitted by the atrioventricular bundle (BUNDLE OF HIS) to the ventricle (HEART VENTRICLE).
Abnormally rapid heartbeat, usually with a HEART RATE above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia.
One of two major pharmacologically defined classes of adrenergic receptors. The beta adrenergic receptors play an important role in regulating CARDIAC MUSCLE contraction, SMOOTH MUSCLE relaxation, and GLYCOGENOLYSIS.
The 10th cranial nerve. The vagus is a mixed nerve which contains somatic afferents (from skin in back of the ear and the external auditory meatus), visceral afferents (from the pharynx, larynx, thorax, and abdomen), parasympathetic efferents (to the thorax and abdomen), and efferents to striated muscle (of the larynx and pharynx).
Drugs that selectively bind to and activate beta-adrenergic receptors.
Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA). In such case, blood cannot be effectively pumped into the lower chambers of the heart (HEART VENTRICLES). It is caused by abnormal impulse generation.
The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from PREVALENCE, which refers to all cases, new or old, in the population at a given time.
Physical activity which is usually regular and done with the intention of improving or maintaining PHYSICAL FITNESS or HEALTH. Contrast with PHYSICAL EXERTION which is concerned largely with the physiologic and metabolic response to energy expenditure.

An infant during the first month after birth.
Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death. (from Braunwald's Heart Disease: A Textbook of Cardiovascular Medicine, 7th ed., 2005)
Drugs used to cause dilation of the blood vessels.
The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.
A device designed to stimulate, by electric impulses, contraction of the heart muscles. It may be temporary (external) or permanent (internal or internal-external).
Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios.
A transferase that catalyzes formation of PHOSPHOCREATINE from ATP + CREATINE. The reaction stores ATP energy as phosphocreatine. Three cytoplasmic ISOENZYMES have been identified in human tissues: the MM type from SKELETAL MUSCLE, the MB type from myocardial tissue and the BB type from nervous tissue as well as a mitochondrial isoenzyme. Macro-creatine kinase refers to creatine kinase complexed with other serum proteins.
A ZINC-dependent carboxypeptidase primary found in the DIGESTIVE SYSTEM. The enzyme catalyzes the preferential cleavage of a C-terminal peptidyl-L-lysine or arginine. It was formerly classified as EC and EC
Resistance and recovery from distortion of shape.
The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.
Obstruction of a blood vessel (embolism) by a blood clot (THROMBUS) in the blood stream.
Calcium-transporting ATPases that catalyze the active transport of CALCIUM into the SARCOPLASMIC RETICULUM vesicles from the CYTOPLASM. They are primarily found in MUSCLE CELLS and play a role in the relaxation of MUSCLES.

  • To resolve these issues, scientists at Bristol and Cambridge Universities have developed a new polymer valve that is both durable and biocompatible (meaning that patients don't need to take blood thinners). (
  • In some cases, blood thinners are used to prevent blood clots from forming. (
  • Blood clots are treated with blood thinners, or anticoagulants. (
  • A new study focusing on the occurrence of clots in knee replacement patients and published in a recent issue of the Journal of Bone and Joint Surgery (JBJS) indicates that despite treatment with blood thinners prior to and immediately following joint replacement surgery, the risk of clot formation is still relatively high in certain patients. (
  • Prophylactic measures, such as the use of blood thinners around the time of surgery, are used to reduce the occurrence of clots, but their effectiveness in routine clinical practice following surgery is more uncertain. (
  • Although knee surgery is still a generally safe procedure, which enables thousands of men and women each year to regain mobility lost to injury or illness, patients should be aware of the risk of post-surgical clotting and talk with their physician about the possible use of blood thinners and follow-up evaluations that may help to identify clots which may be treated before they cause problems. (
  • Although blood thinners are typically prescribed only during hospitalization, the study suggested that physicians consider extending the duration of blood thinner therapy into the weeks following surgery. (
  • Despite the use of blood thinners, patients undergoing knee arthroplasty continue to remain susceptible for clot formation for several weeks following surgery ," Dr. Pedersen said. (
  • Between 300,000 and 600,000 people a year in the United States are diagnosed with a first episode of deep vein thrombosis and, despite standard treatment with blood thinners, roughly half will develop post-thrombotic syndrome. (
  • The procedure is currently used as a second-line treatment to alleviate pain and swelling in people who do not improve on blood thinners. (
  • The study involved 692 patients, randomly assigned to receive blood thinners alone or blood thinners and the procedure. (
  • About 24 percent of people on blood thinners alone experienced moderate to severe pain and swelling, but only 18 percent of people who were treated with blood thinners and clot busters did so. (
  • The vaccine S100A9 may one day be able to replace oral blood thinners to reduce the risk of secondary strokes caused by blood clots, without increasing the risk of serious bleeding or triggering an autoimmune response. (
  • Some doctors' groups are raising the controversial possibility of giving preventive blood thinners to everyone with COVID-19. (
  • The concern is so acute that some doctors groups have raised the controversial possibility of giving preventive blood thinners to everyone with COVID-19 - even those well enough to endure their illness at home. (
  • Even patients on blood thinners in the ICU were developing clots in them - which is not unusual in one or two patients in one unit, but not in so many at the same time. (
  • The American Heart Association is urging doctors to consider therapies in addition to blood thinners to treat certain patients with potentially dangerous blood clots that form in the deep veins and travel to the lungs. (
  • While most patients need blood thinners only, patients with more severe forms of venous thromboembolism may benefit from more aggressive treatments. (
  • Another study published in the Journal of The American College of Cardiology found the risk of thrombotic complications to be so great that COVID-19 patients "may need to receive blood thinners, preventively, prophylactically," even before imaging tests are ordered, said Behnood Bikdeli who is a doctor at New York-Presbyterian Hospital. (
  • Brosnahan suggests that thinners may be effective in some COVID-19 patients but they may not work for all patients because the clots may be too small at times. (
  • The clotting risk factor is particularly severe for the recipients of mechanical heart valves, where the patients must receive blood thinners every day to combat the risk of stroke. (
  • Life without blood thinners? (
  • Because of the high risk of clotting, all these people must take blood thinners, every day, and for the rest of their lives. (
  • If the design of the heart valves is improved from a fluid mechanics point of view, it is conceivable that recipients of these valves would no longer need blood thinners. (
  • Several natural blood thinners may promote heart health. (
  • Make sure not to take Vitamin K when on blood thinners. (
  • How Long Do Patients With Clots in the Lung Need Blood Thinners? (
  • Doctors often prescribe blood thinners that let them live with the clot and avoid surgery. (
  • Since Amy was only 36 years old, Dr. Chaer knew blood thinners weren't the right treatment for her active lifestyle. (
  • Anticoagulation (blood thinners) remains the mainstay of therapy, and may be needed for as little as three months, but can be lifelong treatment. (
  • In the rare circumstances in which blood thinners cannot be used or do not seem to be working, your physician may suggest an inferior vena cava (IVC) filter. (
  • Blood clots (thromboembolism) in the lungs, legs and brain (ischaemic stroke) contribute to disability and the death of patients with heart failure. (
  • A designer molecule developed by Monash University researchers opens the way for a powerful new treatment targeting life-threatening blood clots that cause heart attack or stroke - significantly reducing the risk of permanent brain damage or disability. (
  • Heart attack and stroke are leading causes of death and long-term disability in Australia, and are mostly caused by clotting (thrombosis) blocking blood to the heart or brain. (
  • He said developing a drug with a better safety profile could open the way for treatment to be administered by paramedics at the scene of a patient who'd experienced an ischaemic stroke. (
  • One of the real risks associated with current clot-busting drugs is that they affect the whole body and make bleeding more likely, which in some cases can cause serious issues such as stroke and gastrointestinal bleeding. (
  • Inflammatory bowel disease had no effect on risk of postoperative myocardial infarction (heart attack) or stroke. (
  • CHICAGO (May 15, 2020): When researchers from the University of Colorado Anschutz Medical Campus, Aurora, used a combination of two specific blood-clotting tests, they found critically ill patients infected with Coronavirus Disease 2019 (COVID-19) who were at high risk for developing renal failure, venous blood clots, and other complications associated with blood clots, such as stroke. (
  • Cardiovascular disease includes coronary heart disease (angina and myocardial infarction), stroke, or transient ischaemic attacks. (
  • You should call the emergency medical services in your area, usually 911, if you are having a stroke or heart attack. (
  • People with a history of cardiovascular disease, stroke, and blood clots have an increased risk of developing DVT. (
  • The Duke researchers also found almost half of warfarin-treated patients who might have qualified for tPA following stroke did not receive treatment, according to DCRI Director Eric Peterson, M.D., the paper's senior author. (
  • We noted a substantial under-treatment of patients on warfarin who were eligible, but did not receive tPA following their stroke. (
  • Warfarin is an anticoagulant proven to reduce the rate of stroke in patients with atrial fibrillation - irregular heart beats. (
  • If warfarin treatment fails and the patient suffers a stroke, tPA is the only effective treatment. (
  • The Duke observational trial included 23,437 stroke patients on warfarin treated at 1,203 hospitals, making it the largest to look at IV tPA use in warfarin-treated patients following stroke. (
  • NEW ORLEANS - Clot-busting drugs may be safe for patients who wake up experiencing stroke symptoms, according to preliminary research presented at the American Stroke Association's International Stroke Conference 2012. (
  • Not knowing when the stroke began excludes these patients from anti-clotting drugs that must be given within 4.5 hours of the beginning of the stroke. (
  • Because wake-up strokes are common, occurring in up to a quarter of stroke sufferers, more research is needed on how to treat these patients," said Dulka Manawadu, M.D., lead researcher and a stroke medical consultant at King's College Hospital in London, U.K. (
  • Patients who experience stroke symptoms should call Emergency Medical Services urgently and get to the hospital fast, regardless of the time of onset. (
  • In the study, researchers used a stroke registry to compare clot busting treatments received by 326 patients within 4.5 hours of symptom onset to 68 wake-up stroke patients, with unknown onset. (
  • All the patients were treated in the same London medical center, where 20 percent suffered wake-up stroke. (
  • Our study shows that administering clot-busting drugs to patients with wake-up stroke who have the same clinical and imaging features as those treated within current guidelines is feasible and safe," Manawadu said. (
  • Wake-up stroke patients received clot-busting treatments if their clinical presentation and early stroke changes on CT scan images were comparable to those treated with a known time of onset. (
  • Both groups had similar blood pressure, blood sugar levels and scores on the National Institutes of Health Stroke Scale, which is a standardized method used by healthcare professionals to measure the level of impairment caused by a stroke. (
  • After three months, the researchers found the wake-up stroke patients' death rates, risk of bleeding inside the brain, and the proportion that made a good recovery were similar to those patients treated within a known 4.5 hours of stroke onset. (
  • Sometimes, doctors are reluctant to give clot-busting drugs to patients in whom the time of stroke onset is not known, because the risks of bleeding are not known, Manawadu said. (
  • However, a significant proportion of patients who have stroke symptoms on waking may have suffered stroke in the early hours of the morning and may still be within the window of time where clot-busting treatments are known to be effective. (
  • It is also likely that advanced imaging techniques may help to identify patients with wake-up stroke who have the potential to benefit from clot-busting drugs. (
  • The coronavirus disease COVID-19 is causing excessive blood clotting and stroke in young and healthy people, a new study has found. (
  • The researchers noted that excessive blood clotting and stroke occur in some COVID-19 patients. (
  • In some cases, a stroke may also lead to a ruptured blood vessel, causing bleeding in the brain. (
  • A stroke occurs when a blood clot obstructs the vessel supplying blood to the brain. (
  • The study authors recommend that traditional stroke treatments such as tissue plasminogen activators (tPA), which are proteins that break down blood clots, and the surgical removal of big clots in the brain can be suitable interventions for patients with COVID-19 who had a stroke. (
  • The leading causes of death among people with this disease are heart disease and stroke. (
  • DVT (a blood clot in a vein) does not usually cause a heart attack or a stroke. (
  • Many ischemic stroke patients do not get tPA, which can decrease their chances for recovery. (
  • Patients treated in large, urban hospitals, stroke-certified hospitals and hospitals participating in the American Heart Association's Get With The Guidelines®─Stroke program are more likely to get tPA. (
  • If administered within 4.5 hours of the first signs of stroke, tPA can dissolve the blood clot and restore blood flow to the affected part of the brain. (
  • The study reviewed records from the National Inpatient Sample of 563,087 patients (median age 74) who had an ischemic stroke between 2005 and 2011. (
  • Researchers also found that patients discharged from a designated stroke center or a hospital participating in the American Heart Association's Get With The Guidelines ® ─Stroke program were more likely to receive tPA. (
  • Madsen said that the growing number of hospitals participating in the Get With The Guidelines ® ─Stroke program and legislation requiring emergency services to take stroke patients to regional stroke centers are likely to increase the number of patients receiving tPA. (
  • The study is also limited because we were not able to adjust for patient level factors such as time to arrival and other tPA exclusion criteria, stroke severity, patient education, and socioeconomic status. (
  • There is also a lot of work to do in the realm of stroke education so that patients recognize stroke symptoms and call EMS immediately," Madsen said. (
  • According to the American Heart Association's Heart Disease and Stroke Statistical Update , 795,000 Americans have a stroke every year, causing almost 129,000 deaths. (
  • The study was funded by the American Heart Association/American Stroke Association Founders Affiliate, and the Northeast Cerebrovascular Consortium. (
  • Anti-platelet medications, such as aspirin, are commonly prescribed to prevent heart attack or stroke. (
  • The plaques in atherosclerotic vessels can occasionally rupture, causing the formation of a platelet plug that clogs blood vessels and can lead to heart attack or stroke. (
  • this drug is used to prevent the formation of blood clots in patients with a history of heart attack or stroke. (
  • Errant blood clots of a larger size can break off and travel to the brain or heart, causing a stroke or a heart attack. (
  • To download the free app Heart_Rhythm Heart Rhythm App finds risk for onset of Stroke Risk by SoftRobo, get iTunes now. (
  • This App is useful to know of your stroke risk, by recording of your heart rhythm on the graph. (
  • Record your heart rhythm by iPhone camera and check your stroke risk. (
  • Screen shot of your heart rhythm is taken when the heart rhythm graph is stabilized, and you can check of your stroke risk by comparing your pulse record against irregular pulse record. (
  • However, all blood clots can have potentially fatal effects if left untreated, including heart attack and stroke. (
  • Blood clots are not only dangerous to limbs they can also find their way to the lungs, heart, or brain to cause lethal pulmonary embolisms, stroke, or heart attack. (
  • These clots grow slowly until they may be carried along by the bloodstream and cause stroke by blocking an artery in the brain. (
  • Such a blood flow without turbulence would significantly reduce the chance of clot formation and stroke. (
  • The results show that alpha defensin speeds up blood clot formation, which can cause pulmonary embolism, heart attacks and stroke. (
  • Though blood clotting is the root cause of many life-threatening cardiac events, including heart attack and stroke, scientists didn't know until now that cardiac myosin was implicated in that process. (
  • Adults missing one or more teeth from nontraumatic events more prone to heart attack, stroke. (
  • MINS can affect patients who undergo hip or knee replacement, bowel resection, or abdominal aortic aneurysm repair, among other major surgical procedures, which can then lead to severe complications, including heart attack, stroke, blood clots, amputations and death. (
  • This can lower your risk of a stroke or heart attack. (
  • The CHARISMA study, for example, suggested that long-term dual antiplatelet therapy in patients with vascular disease reduces death, MI, and stroke, but that benefit may not be specific to DES. (
  • Symptoms of a stroke (blood clot in an artery of the brain) include possible loss of speech , vision, profound dizziness , and weakness on one side of the body. (
  • Serious and even life-threatening complications may arise from blood clots, and individuals should seek emergency medical care if they believe they may have a blood clot, especially if signs and symptoms of a heart attack or stroke occur. (
  • Stroke , a blockage in the blood supply to the brain. (
  • It's not immediately life-threatening, but over time it can cause a stroke or lead to heart failure. (
  • FRIDAY, Feb. 3 (HealthDay News) -- A major head-to-head trial finds that aspirin is equally as good as warfarin in preventing stroke and death in heart failure patients. (
  • Heart failure patients are at increased risk for blood clots , stroke and death. (
  • Death, ischemic stroke (caused by blockage of an artery carrying blood to the brain) or bleeding inside the brain (intracerebral hemorrhage) occurred in about 8 percent of the patients taking aspirin and about 7.5 percent of those taking warfarin. (
  • While warfarin users had half the stroke risk of those on aspirin, the overall risk for stroke for patients in either group was considered low. (
  • Although there was a warfarin benefit for patients treated for four or more years, overall, warfarin and aspirin were similar," lead author Dr. Shunichi Homma, a professor of medicine at Columbia University in New York City, said in a stroke association news release. (
  • In the past, the only reason to put heart failure patients on warfarin was in the case of patients with a history of strokes, transient ischemic strokes (TIA or 'mini-stroke') or an irregular heart rhythm. (
  • Help to prevent blood clots that can cause stroke. (
  • Lower elevated blood pressure (hypertension) and prevent complications from high blood pressure such as heart attack and stroke. (
  • Treating AF is important as it may increase the risk of blood clots and stroke. (
  • FRIDAY, Aug. 23 (HealthDay News) -- The use of a potentially lifesaving, clot-busting drug -- called tissue plasminogen activator (tPA) -- to treat patients with ischemic stroke nearly doubled between 2003 and 2011, according to a large new study. (
  • An ischemic stroke occurs when a clot blocks blood flow to the brain. (
  • Researchers analyzed data from over 1 million ischemic stroke patients treated at nearly 1,700 U.S. hospitals between 2003 and 2011. (
  • All of the hospitals in the study were part of an American Heart Association quality improvement program to increase adherence to stroke guidelines. (
  • There was also increased use of tPA to treat patients with less serious stroke symptoms, those aged 80 and over, and black, Hispanic and other nonwhite patients, according to the study published online Aug. 20 in the journal Circulation: Cardiovascular Quality and Outcomes . (
  • Hospitals have put tremendous efforts in the past decade into increasing the number of patients who can be treated with intravenous tPA, and this paper suggests those efforts are paying off," study corresponding author Dr. Lee Schwamm, executive vice chair of neurology and director of stroke services at Massachusetts General Hospital, and a professor of neurology at Harvard Medical School, said in a hospital news release. (
  • Today, more than three-quarters of stroke patients who are eligible for IV tPA are getting this treatment at the more than 1,600 U.S. hospitals we studied," he added. (
  • Patients and their loved ones need to recognize the signs of a stroke and get to the hospital quickly by calling 911, and hospitals need to be ready to provide rapid diagnosis and treatment," Schwamm said. (
  • Fifteen million people globally have a stroke each year and anti-clotting therapies are a big business worth billions of dollars a year. (
  • When a CT scan revealed a 24-inch clot stretching from his legs into his heart, doctors feared the mass could break loose and lodge in his lungs, blocking oxygen and killing him instantly. (
  • Every moment that passed increased the risk that the clot would migrate to his lungs and kill him. (
  • Nearly 100,000 Americans die each year when a clot breaks away from the blood-vessel wall and lodges in the lungs or heart. (
  • blood clot in blood vessels in the lungs) following surgical procedures. (
  • The clots can be fatal if they break off and are carried to the lungs, blocking the flow of blood - a condition called pulmonary embolism. (

  • The researchers of the study also noted that some patients are on their way to recovery, but then, they just stop breathing. (
  • The researchers also noted that the blood of the patients would have high levels of D-dimer , which is a protein produced when a clot is degraded. (
  • An important limitation of the study data is that researchers could not determine why patients did not receive tPA. (
  • Hadassah researchers discovered that the patients who form these fatal clots have an increased level of alpha defensin protein in their blood, explained Dr. Abd Alrauf Higavi, who directs a lab at Hadassah and has been studying blood clots for 30 years. (

  • They instill a drug known as tissue plasminogen activator through the tube, give it time to digest the clot and then suck out or grind up any remaining fragments using specialized catheter-mounted devices. (
  • While a small amount of cardiac myosin might help reduce bleeding in the heart, an excess of the protein may worsen the injury by promoting blood clots that cut off oxygen and exacerbate damage to heart tissue. (
  • Griffin and his team are now working with scientists at Calibr, the drug discovery and development division of Scripps Research, to create a therapeutic compound that would target the procoagulant activity of cardiac myosin, reducing tissue damage caused by a heart attack. (
