Method in which repeated blood pressure readings are made while the patient undergoes normal daily activities. It allows quantitative analysis of the high blood pressure load over time, can help distinguish between types of HYPERTENSION, and can assess the effectiveness of antihypertensive therapy.
The number of times the HEART VENTRICLES contract per unit of time, usually per minute.
Drugs used in the treatment of acute or chronic vascular HYPERTENSION regardless of pharmacological mechanism. Among the antihypertensive agents are DIURETICS; (especially DIURETICS, THIAZIDE); ADRENERGIC BETA-ANTAGONISTS; ADRENERGIC ALPHA-ANTAGONISTS; ANGIOTENSIN-CONVERTING ENZYME INHIBITORS; CALCIUM CHANNEL BLOCKERS; GANGLIONIC BLOCKERS; and VASODILATOR AGENTS.

Persistent high BLOOD PRESSURE due to KIDNEY DISEASES, such as those involving the renal parenchyma, the renal vasculature, or tumors that secrete RENIN.
A response by the BARORECEPTORS to increased BLOOD PRESSURE. Increased pressure stretches BLOOD VESSELS which activates the baroreceptors in the vessel walls. The net response of the CENTRAL NERVOUS SYSTEM is a reduction of central sympathetic outflow. This reduces blood pressure both by decreasing peripheral VASCULAR RESISTANCE and by lowering CARDIAC OUTPUT. Because the baroreceptors are tonically active, the baroreflex can compensate rapidly for both increases and decreases in blood pressure.

A BLOOD PRESSURE regulating system of interacting components that include RENIN; ANGIOTENSINOGEN; ANGIOTENSIN CONVERTING ENZYME; ANGIOTENSIN I; ANGIOTENSIN II; and angiotensinase. Renin, an enzyme produced in the kidney, acts on angiotensinogen, an alpha-2 globulin produced by the liver, forming ANGIOTENSIN I. Angiotensin-converting enzyme, contained in the lung, acts on angiotensin I in the plasma converting it to ANGIOTENSIN II, an extremely powerful vasoconstrictor. Angiotensin II causes contraction of the arteriolar and renal VASCULAR SMOOTH MUSCLE, leading to retention of salt and water in the KIDNEY and increased arterial blood pressure. In addition, angiotensin II stimulates the release of ALDOSTERONE from the ADRENAL CORTEX, which in turn also increases salt and water retention in the kidney. Angiotensin-converting enzyme also breaks down BRADYKININ, a powerful vasodilator and component of the KALLIKREIN-KININ SYSTEM.

Phasic right coronary artery blood flow in conscious dogs with normal and elevated right ventricular pressures. (1/1429)

We studied phasic right coronary blood flow in well trained normal dogs and dogs with pulmonic stenosis. We installed electromagnetic flow transducers and pressure tubes under anesthesia to monitor right coronary blood flow, cardiac output, central aortic blood pressure, and right ventribular pressure. In normotensive dogs, systolic flow amplitude equaled early diastolic flow levels. The ratio of systolic to diastolic flow at rest was substantially greater in the right coronary bed (36+/-1.3%) than in the left circumflex bed (13+/-3.6%). Right diastolid flow runoff, including the cove late in diastole, resembled left circumflex runoff. Blood flow to the normotensive right (37+/-1.1 ml/min 100(-1) g) and the left (35+/-1.0 ml/min(-1) g) ventricular myocardium indicated equal perfusion of both cardiac walls. Throttling of systolic flow was related directly to the right ventricular systolic pressure level in the dogs with pulmonic stenosis. Retrograde systolic flow occurred in severe right ventricular hypertension. The late diastolic runoff pattern in dogs with pulmonic stenosis appeared the same as for the normotensive dogs. We obtained systolic to diastolic flow ratios of 1/3 the value of normotensive hearts in high and severe pulmonic hypertension. Electrocardiograms and studies of pathology suggested restricted blood flow to the inner layers of the right myocardium in the dogs with severe and high right ventricular hypertension. Normotensive and hypertensive peak hyperemic flow responses were similar, except for an increased magnitude of diastolic flow, with proportionately less systolic flow in hypertensive states.  (+info)

Reduction in baroreflex cardiovascular responses due to venous infusion in the rabbit. (2/1429)

We studied reflex bradycardia and depression of mean arterial blood pressure (MAP) during left aortic nerve (LAN) stimulation before and after volume infusion in the anesthetized rabbit. Step increases in mean right atrial pressure (MRAP) to 10 mm Hg did not result in a significant change in heart rate or MAP. After volume loading, responses to LAN stimulation were not as great and the degree of attenuation was propoetional to the level of increased MRAP. A change in responsiveness was observed after elevation of MRAP by only 1 mm Hg, corresponding to less than a 10% increase in average calculated blood volume. after an increase in MRAP of 10 mm Hg, peak responses were attenuated by 44% (heart rate) and 52% (MAP), and the initial slopes (rate of change) were reduced by 46% (heart rate) and 66% (MAP). Comparison of the responses after infusion with blood and dextran solutions indicated that hemodilution was an unlikely explanation for the attenuation of the reflex responses. Total arterial baroreceptor denervation (ABD) abolished the volume-related attenuation was still present following bilateral aortic nerve section or vagotomy. It thus appears that the carotid sinus responds to changes inblood volume and influences the reflex cardiovascular responses to afferent stimulation of the LAN. On the other hand, cardiopulmonary receptors subserved by vagal afferents do not appear to be involved.  (+info)

Ventricular pressure-volume curve indices change with end-diastolic pressure. (3/1429)

Many indices have been proposed to describee the diastolic pressure-volume curve mathematically and permit quantification of the elastic properties of the myocardium itself in hopes that changes in the muscle caused by disease would b.e reflected in the diastolic pressure-volume curve. To date, none of the proposed indices has been shown convincingly to discriminate one group of patients from another. While this situation in part arises from the relatively large amount of noise introduced by the technical difficulties of measuring synchronous pressures and volumes during diastole in man, ther is a more fundamental difficulty. In practice, one can measure only a short segment of the entire pressure-volume curve, and the values of all diastolic pressure-volume curve parameters investigated change significantly when one uses different segments of the same pressure-volume curve to compute them. These results were derived from relatively noise-free pressure-volume curves obtained by filling nine excised dog left ventricles at a known rate and monitoring pressure-volume curve used to compute the parameter. Merely increasing measurement fidelity will not resolve this problem, because none of these parameters accurately characterizes the entire diastolic pressure-volume curbe from a segment like that which one can reasonably expect to obtain from humans.  (+info)

'Home hypertension': exploring the inverse white coat response. (4/1429)

BACKGROUND: The classical 'white coat response' to blood pressure measurement has been studied thoroughly. However, little is known about patients showing a reverse pattern, i.e. who have lower blood pressure readings at the clinic than outside healthcare facilities. AIM: To estimate the proportion of patients whose blood pressure levels as determined by self-measurements at home are higher than those taken at the clinic and to explore possible associations with demographic, clinical, and psychological variables. METHOD: Patients consecutively attending (n = 214) an academic family medicine department in Toronto, Canada, were eligible. Subjects aged below 16 years and those on psychotropic or blood pressure-lowering agents were excluded. The clinic-home blood pressure difference (CHBPD) was calculated for each participating subject by subtracting home blood pressure from clinic blood pressure. Those who had negative values were compared with the rest of the sample. RESULTS: A considerable proportion of patients had lower blood pressure at the clinic than at home (systolic, 34.6%; diastolic, 23.8%). These subjects did not differ from the rest of the sample with regard to age, sex, levels of education attained, immigration status, body mass index, experience of current symptoms, blood pressure levels, or psychological distress. However, in patients with a 'negative CHBPD', i.e. lower blood pressure at the clinic than at home, readings taken by an automatic, self-inflating device when still at the clinic were higher than in the rest of the sample. CONCLUSION: The results point to measurement bias being at least partly responsible for higher blood pressure readings outside the clinic. Automatic measurement devices used for self/home blood pressure measurement seem to cause an alerting reaction analogous to the well-described 'white coat response'.  (+info)

Energy cost of sport rock climbing in elite performers. (5/1429)

OBJECTIVES: To assess oxygen uptake (VO2), blood lactate concentration ([La(b)]), and heart rate (HR) response during indoor and outdoor sport climbing. METHODS: Seven climbers aged 25 (SE 1) years, with a personal best ascent without preview or fall (on sight) ranging from 6b to 7a were assessed using an indoor vertical treadmill with artificial rock hand/foot holds and a discontinuous protocol with climbing velocity incremented until voluntary fatigue. On a separate occasion the subjects performed a 23.4 m outdoor rock climb graded 5c and taking 7 min 36 s (SE 33 s) to complete. Cardiorespiratory parameters were measured using a telemetry system and [La(b)] collected at rest and after climbing. RESULTS: Indoor climbing elicited a peak oxygen uptake (VO2climb-peak) and peak HR (HRpeak) of 43.8 (SE 2.2) ml/kg/min and 190 (SE 4) bpm, respectively and increased blood lactate concentration [La(b)] from 1.4 (0.1) to 10.2 (0.6) mmol/l (p < 0.05). During outdoor climbing VO2 and HR increased to about 75% and 83% of VO2climb-peak and HRpeak, respectively. [La(b)] increased from 1.3 (0.1) at rest to 4.5 mmol/l (p < 0.05) at 2 min 32 s (8 s) after completion of the climb. CONCLUSIONS: The results suggest that for elite climbers outdoor sport rock climbs of five to 10 minutes' duration and moderate difficulty require a significant portion of the VO2climb-peak. The higher HR and VO2 for outdoor climbing and the increased [La(b)] could be the result of repeated isometric contractions, particularly from the arm and forearm muscles.  (+info)

Ankle-arm index as a predictor of cardiovascular disease and mortality in the Cardiovascular Health Study. The Cardiovascular Health Study Group. (6/1429)

Peripheral arterial disease (PAD) in the legs, measured noninvasively by the ankle-arm index (AAI) is associated with clinically manifest cardiovascular disease (CVD) and its risk factors. To determine risk of total mortality, coronary heart disease, or stroke mortality and incident versus recurrent CVD associated with a low AAI, we examined the relationship of the AAI to subsequent CVD events in 5888 older adults with and without CVD. The AAI was measured in 5888 participants >/=65 years old at the baseline examination of the Cardiovascular Health Study. All participants had a detailed assessment of prevalent CVD and were contacted every 6 months for total mortality and CVD events (including CVD mortality, fatal and nonfatal myocardial infarction, congestive heart failure, angina, stroke, and hospitalized PAD). The crude mortality rate at 6 years was highest (32.3%) in those participants with prevalent CVD and a low AAI (P<0.9), and it was lowest in those with neither of these findings (8.7%, P<0.01). Similar patterns emerged from analysis of recurrent CVD and incident CVD. The risk for incident congestive heart failure (relative risk [RR]=1.61) and for total mortality (RR=1.62) in those without CVD at baseline but with a low AAI remained significantly elevated after adjustment for cardiovascular risk factors. Hospitalized PAD events occurred months to years after the AAI was measured, with an adjusted RR of 5.55 (95% CI, 3.08 to 9.98) in those at risk for incident events. A statistically significant decline in survival was seen at each 0.1 decrement in the AAI. An AAI of <0.9 is an independent risk factor for incident CVD, recurrent CVD, and mortality in this group of older adults in the Cardiovascular Health Study.  (+info)

Anthropometric, lifestyle and metabolic determinants of resting heart rate. A population study. (7/1429)

AIM: To clarify the determinants of resting heart rate at the population level in a random sample of the Belgian population. METHODS AND RESULTS: Data of 5027 men and 4150 women aged 25-74 years obtained from a Belgian nationwide survey were analysed. In multivariate analysis, blood pressure strongly correlated with heart rate in men (t = 12.4 for systolic; t = 8.8 for diastolic) and women (t = 12.0 for systolic; t = 7.7 for diastolic). Age (t = -3.4 in men; t = -8.1 in women) and height (t = -3.7 in men; t = -3.1 in women) correlated negatively with heart rate. Smoking raised heart rate in men (1-19 cigarettes.day-1, t = 6.1; > or = 20 cigarettes.day-1, t = 10.3) and women (> or = 20 cigarettes.day-1, t = 3.5). Serum phosphorus correlated negatively with heart rate (t = -3.5 in men; t = -8.3 in women). Serum log alkaline phosphatase (t = 6.7 in men; t = 7.2 in women) and serum protein (t = 5.3 in men; t = 4.4 in women) correlated positively with heart rate. CONCLUSION: At the population level, blood pressure, cigarette smoking, serum alkaline phosphatase and serum protein correlate independently, significantly and positively with heart rate, and age, height and serum phosphorus negatively.  (+info)

Resistance to remnant nephropathy in the Wistar-Furth rat. (8/1429)

The Wistar-Furth rat, an inbred strain resistant to actions of mineralocorticoids, was used to study the concept that mineralocorticoids contribute to progressive renal injury. It was postulated that if chronic nephropathy depends on aldosterone and if Wistar-Furth rats are resistant to aldosterone, remnant nephropathy would be attenuated in Wistar-Furth rats. Wistar-Furth rats and control Wistar rats were subjected to 5/6 nephrectomy or a sham procedure and then followed for 4 wk. Renal ablation resulted in hypertension at 4 wk in both strains (164+/-5 [Wistar-Furth] versus 184+/-7 [Wistar] mm Hg mean arterial pressure), with sham animals remaining normotensive (134+/-6 mm Hg). Renal damage in response to 5/6 nephrectomy was greatly decreased in Wistar-Furth rats compared with Wistar rats. Albuminuria was markedly less in Wistar-Furth rats (12.7+/-4.2 [Wistar-Furth] versus 97.4+/-22.6 [Wistar] mg/d per 100 g body wt, P<0.01). Glomerular damage, consisting of mesangial proliferation, mesangial lysis, and segmental necrosis, was observed in 42% of glomeruli from Wistar rats but in 0% of glomeruli from Wistar-Furth rats (P<0.01). To address the possibility that higher BP in partially nephrectomized Wistar rats mediated the greater renal damage, the study was repeated, with Wistar rats (not Wistar-Furth rats) being treated with a hydralazine-reserpine-hydrochlorothiazide regimen. Although this antihypertensive regimen equalized BP (conscious systolic) (144+/-8 mm Hg [Wistar] versus 157+/-7 mm Hg [Wistar-Furth] at 4 wk), albuminuria remained more than 10-fold greater in Wistar rats. In summary, renal damage upon 5/6 nephrectomy was markedly reduced in Wistar-Furth rats, a finding not attributable to reduced systemic BP. Since Wistar-Furth rats have been shown previously to be resistant to the actions of mineralocorticoids, the data from the present study support the hypothesis that aldosterone mediates, at least in part, the renal injury attendant to renal mass reduction.  (+info)

Did you ever wonder how your automatic blood pressure cuff actually works? No? Just me? Well…no surprise there.. When the machine inflates the cuff, its goal is to get it above the patients systolic blood pressure (table how it knows that for one second). It then uses this as its estimate for the next time it cycles. Incidentally, this is why the first pressure cycled on a new patient can be remarkably uncomfortable sometimes, or take a really long time.. While the cuff is cycling, a pressure sensor in the machine is looking for variance of the oscillations of the pressure in the cuff. When the cuff pressure exceeds the patients SBP there is no flow in the limb, and when the cuff pressure is below the patients DBP there is smooth flow in the limb, and the cuff pressure oscillations dont vary much. In between, there are variable amplitude micro-oscillations measurable in the cuff with each beat as some blood is squished through the artery.. ...
Continuous and noninvasive blood pressure (BP) measurement has been a topic of study for years, and many commercial devices have been available. The most commonly used technologies (applanation tonometry and vascular unloading method) have a shortcoming of complex mechanical structure. In this thesis, a new and systematic methodology of continuous and noninvasive BP measurement by pulse wave velocity (PWV) is established for people with healthy cardiovascular system. To avoid complex and high-cost sensor or control system, arterial pulse waves are acquired using the easy-to-use, low-cost and technically mature photoplethysmography (PPG) sensors. Critical parts of this study include modeling BP-PWV relationship, determining two PWVs related to systolic blood pressure (SBP) and diastolic blood pressure (DBP) respectively, and verifying the modeling methodology by practical BP measurement using PWV. The measurement results from a small population satisfy the accuracy criteria of the Association ...

Getting reliable blood pressure readings in patients with obesity can pose a problem, even when extra-large cuffs are available. An often discussed alternative is the use of forearm readings using a regular cuff, but the reliability of these readings remains unknown.. Now a study by Marie-Eve Leblanc and colleagues from the University of Laval, Quebec, Canada, published in Blood Pressure Monitoring, shows that forearm measurements with an oscillometric device can be reliably measured and are highly predictive of intra-arterial blood pressure measurements in patients with sever obesity.. The study involved 25 participants with an average BMI of 50.9kg/m2. Overall, sensitivity (0.98) and predictive values (0.93) for the presence of systemic hypertension were excellent, indicating that the forearm approach is a promising alternative to systemic hypertension diagnosis in severe obesity.. This may well simplify blood pressure measurements in patients presenting with severe obesity, where upper arm ...

All blood pressure measurements were obtained in participants homes according to the [Hypertension Detection and Follow-up Program] protocol. On each occasion, blood pressure was measured 3 consecutive times with 30 seconds between measurements using mercury sphygmomanometers on seated subjects with the arm resting at heart level. For analyses of each time point, the average of the 3 blood pressure measurements was used. A more detailed description of the blood pressure procedures has been published previously.34 All interviewers passed a written test, a videotaped test of blood pressure readings, and live practice tests with a supervisor using a split stethoscope. The overall mean of blood pressure readings by trainees had to be within ±1.96 mm Hg of the standard mean on the videotaped test.35 Data from the HDFP on blinded duplicate blood pressure readings demonstrated good reproducibility of trainee readings ...

A noninvasive blood pressure measuring system includes an inflatable cuff for encircling a portion of the human body. The cuff is inflated to a pressure sufficient to occlude arterial flow, and the pressure is then released by opening of a pressure relief valve for short periods of time to reduce the pressure until both the systolic and diastolic events have occurred. The incremental decrease in pressure with each opening of the pressure relief valve is controlled by monitoring the pressure before opening and after closing the pressure relief valve. The time duration of the next valve opening cycle is controlled as a function of the comparison of the two pressures so as to maintain an average incremental decrease in pressure. In addition to systolic and diastolic blood pressures, pulse rate is also determined by counting the number of pulses between the systolic and diastolic events and determining the time elapsed between the two events. After occurrence of the systolic event, the valve is opened

We present data based on two surveys four years apart (1987 and 1991) in Guildford and Carlisle. The sampling and methods used have been detailed elsewhere.6 15 16 Both surveys were carried out in the same sample of 10 primary schools in each town. The second survey included all children from the earlier survey still attending the schools together with similar numbers of children in the same classes. In both surveys measurements were made by a team of trained nurse observers, who visited schools in the two areas in sequence.. Blood pressure was measured after five minutes rest with the child seated and the arm supported at chest level. Three blood pressure measurements were made one minute apart on the right arm with the Dinamap 1846SX oscillometric blood pressure recorder (Critikon Inc, United States).17 All analyses were based on the means of the three readings. At 9-11 years all measurements were made with the adult size cuff (cuff bladder 22 cm × 12 cm); at 5-7 years all measurements were ...
The results point to the importance of getting multiple measures from different settings. Using just one reading as the basis for prescribing or adjusting blood pressure medication could endanger patients who suffer from white coat hypertension, the researchers say. They recommend using an average of at least six readings to get the best estimate of true blood pressure.. Home monitoring of blood pressure is becoming more popular. About 43 percent of people with high blood pressure use home monitors. Dr. Powers says the study results support recent calls for reimbursement of home blood pressure monitoring.. I think patients should expect their doctors to make decisions based on home blood pressure [in addition to other measures], he says. But, he adds, those who use a home blood pressure monitor should get it validated for accuracy at their doctors office.. Always talk with your health care provider to find out more information.. ...

Our new article of the month comes from Dr. Lochie Milner and is a systemic review and analysis of blood pressure measurements in neonates.. Accurate blood pressure measurements in neonates are fraught with challenges which is influenced by several factors including technique, cuff size and location of measurement. Since hypertension is being seen more frequently in neonates, especially in those with lung disease, the accuracy of neonatal blood pressure measurements is important for therapeutic guidance and potentially preventing long term cardiovascular complications.. This study entitled: Method of blood pressure measurement in neonates and infants: a systematic review and analysis by Dionne et al sheds some light on some of these issues highlighting important aspects and pitfalls in evaluating blood pressures of premature babies in the NICU. Helpful recommendations are offered by the authors which are thought provoking with important implications ...
One of the key health indicators is blood pressure. It used to be that you had to go to a doctors office or clinic to get it measured, but now you can choose from a host of home blood pressure devices, some of which are even connected so that they can store and share your results through a smartphone app or other service. The problem remains that many people find it difficult or awkward to use a pressure cuff on their arm, or even one of the newer wrist designs. A Swiss company, Leman Micro Devices (LMD), thinks that they have the answer: a light sensor built into a smart phone.. Weve written about projects to use light to measure blood pressure before, but this is the first product weve seen that is designed to be incorporated into a smartphone. A sensor is built into the top edge of the phone, and a gaming app gives the user feedback so that they press their finger against the sensor with the right amount of pressure to get a reliable reading. The process takes less than a minute, and the ...

This particular model comes with a USB cable and software that will keep track of the readings over time. This is the top-of-the-line model and cost about $75 on Amazon.. I found this particularly useful because Ive lost a lot of weight over the past year and I suspected (correctly) that my blood-pressure medication was excessive for my current weight, and my blood pressure was actually lower than desirable. My doctor is a great guy (Dr. Shawn Foley at Philomath Family Medicine), and he more or less turned me loose to tune my medication so Im within his guidelines.. Another thing I found out was that I was a little intimidated by the process of having my blood pressure taken, and this tension made my blood pressure rise! So my medication had been tuned to deal with an anomalously high blood pressure. Taking reading a zillion times with this automated machine got me used to it, so now I ...

Pseudohypertension, also known as pseudohypertension in the elderly, noncompressibility artery syndrome, and Oslers sign of pseudohypertension is a falsely elevated blood pressure reading obtained through sphygmomanometry due to calcification of blood vessels which cannot be compressed. There is normal blood pressure when it is measured from within the artery. This condition however is associated with significant cardiovascular disease risk. Because the stiffened arterial walls of arteriosclerosis do not compress with pressure normally, the blood pressure reading is theoretically higher than the true intra-arterial measurement. To perform the test, one first inflates the blood pressure cuff above systolic pressure to obliterate the radial pulse. One then attempts to palpate the radial artery, a positive test is if it remains palpable as a firm tube. It occurs frequently in the elderly irrespective of them being hypertensive, and has moderate to modest intraobserver and interobserver ...

Introduction: The mercury sphygmomanometer has been the gold standard used for obtaining blood pressure (BP). However, due to environmental concerns and more use of automated BP devices, an alternative to using the standard mercury sphygmomanometer to measure BP. The aim of this study is to evaluate the accuracy of the Automated (Omron) BP device against the mercury sphygmomanometer in children.. Material and Methods: One hundred children were enrolled in this study. The accuracy of Omron HEM-7121 BP readings was compared with that of mercury BP device readings. Each children had four BP measurements recorded sequentially i.e. two valid systolic readings, and two valid diastolic readings.. Results: BP taken with the automated device was systolic 109.77 ± 9.97 and diastolic 74.50 ± 8.32 mm Hg compared to systolic 112.68 ± 9.98 and diastolic 77.38 ± 7.91 mm Hg measured by manual mercury sphygmomanometer BP readings (p,0.001). Automated and mercury BP measurements were correlated (r = 0.89, ...

OBJECTIVE: To update the evidence-based recommendations for the prevention and management of hypertension in adults for 2009. OPTIONS AND OUTCOMES: For lifestyle and pharmacological interventions, evidence from randomized controlled trials and systematic reviews of trials was preferentially reviewed. Changes in cardiovascular morbidity and mortality were the primary outcomes of interest. However, for lifestyle interventions, blood pressure lowering was accepted as a primary outcome given the lack of long-term morbidity and mortality data in this field. Progression of kidney dysfunction was also accepted as a clinically relevant primary outcome among patients with chronic kidney disease. EVIDENCE: A Cochrane collaboration librarian conducted an independent MEDLINE search from 2007 to August 2008 to update the 2008 recommendations. To identify additional published studies, reference lists were reviewed and experts were contacted. All relevant articles were reviewed and appraised independently by both

It is important to maintain our health by making a visit to a doctor to get our vital signs measured. Our vital signs consist of blood pressure, pulse (heart rate), body temperature and breathing rate. Basic principle of blood pressure monitor is to measure our systole and diastole respect to our heart rate. Human blood pressure affected by many parameters, it is difficult to get the same blood pressure value in repeated measurement from a patient. Calibration is a process that under specified conditions establishes a relation between the quantity values with measurement uncertainties provided by measurement standards. The traditional relies on the use of the stethoscope, while the digital relies on the process called oscillometric. The concept behind oscillometric process is to simulate every beat of the pulse during a manual blood pressure reading. Automated monitors sense the oscillations of the pulse to establish the average or mean arterial pressure (MAP). Once MAP has been determined, the ...

An exception to this is those with very high blood pressure readings especially when there is poor organ function.[79] Initial assessment of the hypertensive people should include a complete history and physical examination. With the availability of 24-hour ambulatory blood pressure monitors and home blood pressure machines, the importance of not wrongly diagnosing those who have white coat hypertension has led to a change in protocols. In the United Kingdom, current best practice is to follow up a single raised clinic reading with ambulatory measurement, or less ideally with home blood pressure monitoring over the course of 7 days.[79] The United States Preventive Services Task Force also recommends getting measurements outside of the healthcare environment.[80] Pseudohypertension in the elderly or noncompressibility artery syndrome may also require consideration. This condition is believed to be due to calcification of the arteries resulting in abnormally high blood pressure readings with a ...

For an accurate diagnosis of hypertension to be made, it is essential for proper blood pressure measurement technique to be used.[76] Improper measurement of blood pressure is common and can change the blood pressure reading by up to 10 mmHg, which can lead to misdiagnosis and misclassification of hypertension.[76] Correct blood pressure measurement technique involves several steps. Proper blood pressure measurement requires the person whose blood pressure is being measured to sit quietly for at least five minutes which is then followed by application of a properly fitted blood pressure cuff to a bare upper arm.[76] The person should be seated with their back supported, feet flat on the floor, and with their legs uncrossed.[76] The person whose blood pressure is being measured should avoid talking or moving during this process.[76] The arm being measured should be supported on a flat surface at the level of the heart.[76] Blood pressure measurement should be done in a quiet room so the medical ...

AIMS/HYPOTHESIS: The relationship between BP and microalbuminuria in young people with type 1 diabetes is not completely clear. As microalbuminuria is preceded by a gradual rise in albumin excretion within the normal range, we hypothesised that ambulatory BP (ABP) may be closely related to albumin excretion and progression to microalbuminuria. METHODS: ABP monitoring (ABPM) was performed in 509 young people with type 1 diabetes (age median [range]: 15.7 [10.7-22.6] years) followed with annual assessments of three early morning urinary albumin:creatinine ratios (ACRs) and HbA(1c). Systolic BP (SBP) and diastolic BP (DBP) and the nocturnal fall in BP were analysed in relation to ACR. RESULTS: All ABPM variables were significantly related to baseline log(10) ACR (p | 0.001). After the ABPM evaluation, 287 patients were followed for a median of 2.2 (1.0-5.5) years. ABP at baseline was independently related to mean ACR during follow-up. Nineteen initially normoalbuminuric patients developed microalbuminuria
A study reveals that blood pressure not measured according to the AHA recommendations leads to errors which could hamper treatment decisions.. [email protected] Because some clinicians fail to stick to official recommendations for blood pressure monitoring, a number of patients are misclassified, which could have an impact on decisions about their treatment. According to Gretchen Ray and colleagues, from the University of New Mexico College of Pharmacy, when routine blood pressure monitoring in clinics is compared with measurements based on the latest guidelines, 93 percent of patients have different blood pressure readings.. In 2005, the American Heart Association (AHA) released updated recommendations for blood pressure monitoring, to ensure accurate and consistent blood pressure measurements. Numerous factors including body position, arm position, inter-arm differences, cuff size and cuff placement can affect the reading.. Ray and colleagues compared the blood pressure readings of 40 patients ...
The term white coat comes from references to the white coats traditionally worn by doctors. The white coat effect means that your blood pressure is higher when it is taken in a medical setting than it is when taken at home. On average, when your blood pressure is taken at home the top (systolic) number can be around 10mmHg lower than it would be if taken by a doctor and 5mmHg lower on the bottom (diastolic) number. For some people this difference can be even greater.. What causes the white coat effect?. Your blood pressure is not fixed - it rises and falls throughout the day in response to what you are doing and what is happening around you. White coat effects will often happen because you are nervous about having your blood pressure tested by a healthcare professional. Most of us tend to feel tenser in medical settings than we do in surroundings that are familiar to us, although we do not always notice it.. ​. The white coat effect can influence some peoples blood pressure more than ...
Heart disease is still the #1 killer in America and high blood pressure is a big part of that. Do you know what your blood pressure reading is? Do you know what it should be?

  • However, studies of the relationship between blood pressure categories and all-cause mortality in the Chinese adult population are limited, and sex-specific studies of these associations are not available. (cdc.gov)
  • A higher number of childhood/youth observations of abnormal blood pressure did not enhance prediction of adult high-risk intima-media thickness. (nih.gov)
  • This genetic variation may affect pressure response to changes in dietary sodium. (diabetesjournals.org)
  • Genome-wide association studies are complementary to a candidate gene approach and have helped to identify new genetic pathways involved in blood pressure (BP). (diabetesjournals.org)
  • Conclusions- We conclude that human catecholamine secretory traits are heritable, displaying joint genetic determination (pleiotropy) with autonomic activity and finally with blood pressure in the population. (ahajournals.org)
  • Consistent with the human genetic studies, Wnk1 heterozygous mice displayed a significant decrease in blood pressure. (pnas.org)
  • Hypoxemia is usually defined in terms of reduced partial pressure of oxygen (mm Hg) in arterial blood, but also in terms of reduced content of oxygen (ml oxygen per dl blood) or percentage saturation of hemoglobin (the oxygen-binding protein within red blood cells) with oxygen, which is either found singly or in combination. (wikipedia.org)
  • Conclusions Nighttime systolic blood pressure and nighttime diastolic blood pressure were higher among the patients with tinnitus. (biomedsearch.com)
  • Conclusions We conclude that hemiparetic stroke patients may improve their aerobic capacity and submaximal exercise systolic blood pressure response with training. (ahajournals.org)
  • Conclusions could be drawn as to the relative pressure in the arterial system by properly standardizing the equipment. (google.ca)
  • In the TH promoter, significant associations were found for urinary catecholamine excretion and for blood pressure response to stress. (ahajournals.org)
  • TH promoter haplotype 2 (TGGG) showed pleiotropy, increasing both norepinephrine excretion and blood pressure during stress. (ahajournals.org)
  • Measurement under normal everyday conditions enables more accurate determination of the blood pressure values. (dhzb.de)
  • In rats treated with fenofibrate (30 mg·kg −1 ·day −1 ig) or AUDA (50 mg/l in drinking water) for 2 wk, mean arterial pressure, renal vascular resistance, and glomerular filtration rate were lower but renal blood flow was higher than in vehicle-treated control rats. (physiology.org)
  • If the first measurement of blood pressure revealed a high value is important to measure it again. (infobarrel.com)
  • Repeated measurement of blood pressure is especially important given the potential measurement errors and blood pressure variations. (jove.com)
  • Childhood/youth abnormal blood pressure was defined as above 90th or 95th percentile. (nih.gov)
  • Obese pa- index 30 kg.m-2 and in whom intraoperative direct intra-arterial tients will therefore often require large-sized cuffs, which blood pressure measurement was considered mandatory by the over-estimate MAP. (who.int)
  • If the high pressure is not controlled there may be kidney damage. (infobarrel.com)
  • Using the Symplicity device, the procedure saw a catheter threaded through arteries to deliver radiofrequency energy that inactivates kidney nerves, consequently interrupting electrical signals to and from the kidney and altering the regulation of a patient's blood pressure. (acc.org)
  • Zinc Chloride also improved kidney function as determined by the restoration of blood urea and creatinine level. (scirp.org)
  • The kidney plays a central role in our ability to maintain appropriate sodium balance, which is critical to determination of blood pressure. (jci.org)
  • The natural compound improved the rats' kidney function and lowered their blood pressure by normalizing a process called DNA methylation. (mercola.com)
  • It is illustrated in blood pressure measurement of 90-95% medical accuracy without additional accessories. (igi-global.com)
  • Although approximately half of the inter-individual variance in blood pressure (BP) level is heritable, identification of genes responsible for its regulation has remained challenging. (cdc.gov)
