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.

  • The phenomenon of 'white coat hypertension,' and its potential to misclassify many patients' blood pressure control, is well-known. (
  • The hypertension community, represented by the American Society of Hypertension and the European Society of Hypertension, has long recognized the inferiority of clinic blood pressure measurements, especially when not repeated, and has called for greater use of home blood pressure monitoring in position statements. (
  • Objectives The aim of this study is to determine the influence that different risk factors (age, gender, obesity, smoking, inactivity, diabetes mellitus and previous diagnosis of arterial hypertension) have on arterial pressure, and to determine the prevalence of patients that have high blood pressure and hypertension but have not received drug-treatment for arterial hypertension. (
  • It was found that an increase in the number of risk factors led to a corresponding rise in the percentage of patients with high blood pressure and arterial hypertension. (
  • 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. (
  • In addition, children with hypertension (3.4%) or pre-hypertensive levels (6.6%) also had comorbidity for overweight and blood lipid abnormalities (14% for triglycerides, 44.7% for TC, 25.9% for LDL-C, 52% for low HDL-C). The present study shows for the first time high correlations between prehypertensive blood pressure levels and the cardiovascular risk factors high TC, high LDL-C, low HDL-C in schoolchildren. (
  • Clinical and epidemiological studies have suggested that periodic blood pressure (BP) and biochemical determinations in schoolchildren permit the early detection of risk factors and treatment of hypertension and other cardiovascular diseases (1,2). (
  • Hypertension (HTN) affects 1 out of 3 adults in the United States and is a major risk factor for stroke and cardiovascular diseases (CVDs) [ 1 ]. (
  • One of the most important applications of BP measurements is the screening, diagnosis, and monitoring of hypertension, a condition that affects almost one third of the U.S. adult population and is one of the leading causes of the cardiovascular disease. (
  • Singer P, Berger J, Luck K, Tauber CH, Naumann E, Gödicke W (1986) Long-term effect of mackerel diet on blood pressure serum lipids and thromboxane formation in patients with mild essential hypertension. (
  • Hypertension affects 32.6% of the U.S. adult population and is a major risk factor for cardiovascular events and death. (
  • 2 Over time, a compensatory increase in blood pressure (BP) and, consequently, an increase in renal perfusion pressure increase sodium excretion but also induce hypertension. (
  • Overwhelming evidence supports the conclusion that cigarette smoking causes various adverse cardiovascular events 1 2 and acts synergistically with hypertension and dyslipidemia to increase the risk of coronary heart disease. (
  • Smoking causes an acute increase in blood pressure (BP) and heart rate and has been found to be associated with malignant hypertension. (
  • Seated peripheral (brachial) and central (aortic) blood pressures were assessed, and the ratio between aortic and brachial pulse pressure (pulse pressure ratio, ie, 1/amplification) was calculated in healthy individuals, diabetic subjects, patients with cardiovascular disease, and in individuals with only 1 of the following: hypertension, hypercholesterolemia, or smoking. (
  • 70% of individuals with high-normal brachial pressure had similar aortic pressures as those with stage 1 hypertension. (

  • Heightened cardiovascular responses to mental stressors are associated with future risk of hypertension. (
  • Participants included 479 initially healthy men and women (mean age, 62.7 ± 5.6 yr), without history or objective signs of cardiovascular disease or hypertension at study entry. (
  • Blood pressure was measured at study entry and at 3 yr follow-up for the determination of hypertension. (
  • Hypertension is a powerful, consistent and independent risk factor for cardiovascular disease and renal disease. (
  • Managing cardiovascular disease risk in hypertension. (
  • We first used linear regression models to report crude data and then, multivariate adjustment for sociodemographic (age, sex, and race) and cardiovascular risk factors (hypertension, dyslipidemia, diabetes, smoking, body mass index, use of alcohol, and leisure physical activity) using the euthyroid group as reference. (
  • Hypertension is high blood pressure. (
  • Hypertension is serious because people with the condition have a higher risk for heart disease and other medical problems than people with normal blood pressure. (
  • Serious complications can be avoided by getting regular blood pressure checks and treating hypertension as soon as it is diagnosed. (
  • Hypertension makes the heart work harder to pump blood through the body. (
  • If hypertension thickens the arteries to the kidneys, less waste can be filtered from the blood. (
  • Blood pressure in adults will be categorized as normal, elevated, stage 1 hypertension or stage 2 hypertension. (
  • Causes for secondary hypertension could be classified as renal, endocrine, cardiovascular causes. (
  • Our mission is to build healthier lives, free of cardiovascular diseases and stroke. (
  • The study took place in Evans Country because the area had a high death count due to heart complications, such as heart disease and other cardiovascular diseases. (
  • Certain adverse health effects, from high blood pressure to cardiovascular diseases, are directly linked to a high sodium intake. (
  • It is accepted that risk factors for cardiovascular diseases, when detected in schoolchildren, are predictive of coronary disease. (
  • If initiated during early childhood, appropriate changes in lifestyle patterns should be able to reduce the later incidence and severity of cardiovascular diseases (4,5). (

  • Cardiovascular conditions are as common in those with demyelinating diseases (multiple sclerosis, neuromyelitis optica and transverse myelitis). (
  • The purposes of this study is to examine whether there are between-arm differences in simultaneous BP measurements obtained from ambulatory patients without cardiovascular diseases and to identify the factors associated these differences. (
  • The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) is a prospective cohort study that investigates cardiovascular diseases, diabetes, and associated factors, including non-classical cardiovascular risk factors such as thyroid function. (
  • Cardiac rehabilitation (CR) is highly effective as secondary prevention for cardiovascular diseases (CVDs). (
  • Cardiovascular diseases are the leading cause of death worldwide ( /), and acute myocardial infarction (AMI) is one of the major cardiovascular diseases that leads to a high mortality and morbidity. (
  • The logarithms of blood pressures were found to be normally distributed, except for diastolic pressures in the older age groups which were somewhat more skewed than in a log-normal distribution. (
  • Effect of microinjecting 2 µL of 1.5 M NaCl into the anteroventral third ventricular region on diastolic blood pressure in the control rats (n=12) and in those fed the rich-rich diet (n=12). (
  • Mean systolic and diastolic blood pressure increased with increasing age in both sexes. (
  • The mean systolic and diastolic blood pressure of boys and girls in all age groups were significantly lower than the Second Task Force on Blood Pressure Control in Children scale. (
  • Epidemiologic evidence has indicated a U- or J-shaped association of systolic blood pressure (SBP) or diastolic blood pressure (DBP) with all-cause mortality (2-4). (
  • Factors assessed at the time of follow-up were systolic and diastolic blood pressure, serum cholesterol level, cigarette smoking, body weight, hematocrit value, ECG abnormalities and diet. (
  • The blood pressure is measured in mmHg and recorded as a fraction (systolic BP/ diastolic BP). (
  • An auscultatory gap is an intermittent disappearance of Korotkoff sounds after their initial appearance before the true diastole, which may seriously underestimate the systolic pressure or overestimate the diastolic pressure. (
  • No such differences were seen among younger men or for diastolic blood pressure in either age group. (
  • there is at least 20 mm Hg difference in the systolic blood pressure (SBP) and 10 mm Hg difference in the diastolic blood pressure (DBP). (
  • All BP determinations (systolic and diastolic) are taken in the Mobile Examination Center (MEC). (
  • The relationship of left ventricular mass with the stage of sexual maturation and with systolic and diastolic blood pressure was also evaluated. (
  • Blood pressure when the heart is at rest is called diastolic pressure. (
  • When blood pressure is measured, the systolic pressure is stated first and the diastolic pressure second. (
  • For example, if a person's systolic pressure is 120 and diastolic pressure is 80, it is written as 120/80 mm Hg. (
  • Diastolic function was categorised as mild (impaired relaxation without increased filling pressures), moderate (impaired relaxation associated with moderate elevation of filling pressures or pseudonormal filling), or severe (advanced reduction in compliance or reversible or fixed restrictive filling). (
  • Diastolic dysfunction increased with increasing age and the presence of cardiovascular disease, diabetes, and systolic dysfunction. (
  • After resting quietly in a sitting position for 5 minutes and determining the maximum inflation level (MIL), three and sometimes 4 BP determinations (systolic and diastolic) are taken in the mobile examination center (MEC). (
  • The program includes a didactic section, audio-video practice watching and listening to systolic and diastolic blood pressure sounds, and measuring blood pressures of volunteers concurrently with a certified, gold standard BP instructor. (
  • RESULTS: In PBC patients, 1 month's treatment with UDCA significantly reduced diastolic volume without changing systolic, diastolic, and mean blood pressures, heart rate, systolic and stroke volumes, ejection fraction, cardiac output, and systemic vascular resistance. (
  • In PNC patients, UDCA significantly reduced cardiac output, with a tendency to reduce left ventricular volumes, without any changes in systolic, diastolic, and mean blood pressures. (
  • We describe a child in whom the left internal mammary artery (LIMA) was chosen for monitoring arterial blood pressure because of malfunction of the existing posterior tibial arterial pressure line after cardiopulmonary bypass. (
  • When standard arterial monitoring sites are not accessible, internal mammary artery cannulation can provide reliable access for prolonged arterial blood pressure monitoring in the postoperative period in children. (
  • The measurement of arterial blood pressure (BP) is of paramount importance when caring for critically ill patients, as BP, especially mean BP, is the driving force of blood flow through all the organs. (
  • Arterial blood pressure (BP) measurement in children is one of the most important tools in diagnosing their physical health. (
  • Two measurements of arterial pressure were taken from each patient on the first day of the study and two other measurements on a later day. (
  • The average of these four measurements was taken as the arterial pressure value for the patient. (
  • The measurements were noted in the patients' records along with data about the seven risk factors being studied, allowing them to be related with the patient's arterial pressure value. (
  • The first audible Korotkoff sound signifies the maximum arterial pressure during systole. (
  • When the pressure in the cuff is reduced further and falls below the minimal arterial pressure (during diastole), the Korotkoff sounds become no longer audible. (
  • Neurological and cardiologic examinations included 24-hour Holter ECG monitoring and 24-hour blood pressure monitoring with determination of the daily arterial vascular stiffness, echocardiography, laser doppler flowmetry followed by an occlusive test to assess the state of microvasculation, levels of serum vascular cellular adhesion molecule-1 (VCAM-1). (
  • The first attempt to measure arterial blood pressure in human beings is credited to Karl von Vierendt (1818-1884). (
  • Pulse pressure varies throughout the arterial tree, resulting in a gradient between central and peripheral pressure. (
  • After intravenous administration of the compounds to rats, heart rate (HR) and mean arterial pressure were monitored continuously, and serial arterial blood samples were drawn for determination of the pharmacokinetics. (
  • The areas under the receiver operating characteristic curve were slightly higher for SBP and PP compared with mean arterial pressure and DBP for major cardiovascular and coronary events. (

  • Arterial pressure and cerebral blood flow variability: friend or foe? (
  • Variability in arterial pressure and cerebral blood flow has traditionally been interpreted as a marker of cardiovascular decompensation, and has been associated with negative clinical outcomes across varying time scales, from impending orthostatic syncope to an increased risk of stroke. (
  • Traditionally, clinicians have assessed the cardiovascular status of their patients with static "snapshot" techniques, such as radial pulse for heart rate, brachial sphygmomanometry for arterial pressure, and chest excursions for respiration rate. (
  • While the notion that arterial blood pressure is not constant, but fluctuates dynamically over time has been known since the 18th century, the clinical importance of this phenomenon is only now being recognized. (
  • With advances both in monitoring technologies and data analysis capabilities, we now have the capacity to capture dynamic changes in patient status by recording and analyzing non-invasive, high frequency hemodynamic waveform data, including ECG, arterial pressure, and most recently, cerebral blood flow and oxygenation. (
  • 8 The shape of the arterial pressure waveform provides a measure of systemic arterial stiffness 9 and can be assessed noninvasively by using the technique of pulse-wave analysis (PWA). (
  • Geographic variations in cardiovascular disease (CVD) and associated risk factors have been recognized worldwide. (
  • Risk assessment of acute kidney injury in patients with acute cardiovascular disease without invasive intervention]. (
  • OBJECTIVE -Heart rate recovery (HRR) is an independent prognostic indicator for cardiovascular disease (CVD) and all-cause mortality in healthy men. (
  • The purpose of the current research was to evaluate whether slow HRR after maximal exercise predicts cardiovascular disease (CVD) and all-cause mortality among these diabetic men. (
  • The reverse is also applicable, as the presence of cardiovascular disease increases the incidence of creatinine doubling and ESKD ( 7 , 8 ). (
  • Acetylsalicylic acid (ASA) is the most widely prescribed drug to prevent cardiovascular disease. (
  • OBJECTIVE -To determine in normal weight, overweight, and obese men the risk of all-cause and cardiovascular disease (CVD) mortality associated with the metabolic syndrome (MetS) and the influence of cardiorespiratory fitness (CRF). (
  • The aggressive treatment of MetS is important because it is associated with an increased risk of type 2 diabetes ( 3 , 4 ), cardiovascular disease (CVD) ( 3 , 5 ), and premature mortality ( 5 - 7 ). (
  • The study aimed to determine how cardiovascular disease affected different races among a specific population. (

  • If rapid strength and mass gains can be achieved using low cuff pressure-small cuff width BFR methods it represents an intriguing rehabilitation strategy for disuse, injury, and some muscular disease treatments with less concern for patient safety. (
  • An inverse relationship between plasma BNP level and endothelial function has been reported in patients with CVD (cardiovascular disease), including patients with heart failure [ 4 - 7 ]. (
  • In a prospective Dutch study, the magnitude of the enhanced cardiovascular risk in RA was investigated by comparing prevalent cardiovascular disease (CVD) with that of diabetes. (
  • Heart disease and disease of the entire cardiovascular system are the causes of more disability and death than any other disease. (
  • However, the relative impact of cardiovascular risk factors and atheromatous disease on central pressure and the normal variation in central pressure in healthy individuals are unclear. (
  • Cardiovascular disease (CVD) is the leading cause of hospitalization and death in chronic kidney disease (CKD) patients. (
  • Cardiovascular disease (CVD) is the leading cause was thought before now to cause gouty nephropathy of hospitalization and death in chronic kidney by causing deposition of urate crystals in the kidney, disease (CKD) patients at all stages[1] and accounts but recent studies have now shown that uric acid can for about 50% mortality in this group of patients. (
  • CKD to endstage renal disease, reduce cardiovascular uric acid, creatinine, and fasting serum lipids. (
  • Use of thoracic impedance sensors to screen for sleep-disordered breathing in patients with cardiovascular disease. (

  • Racial Differences in Associations of Blood Pressure Components in Young Adulthood With Incident Cardiovascular Disease by Middle Age: Coronary Artery Risk Development in Young Adults (CARDIA) Study. (
  • It's not a new epidemic or disease - it's high blood pressure, the "silent killer. (
  • Many more people than previously believed are at risk for this far too common condition that increases the chance for heart disease and stroke, according to a new guideline for high blood pressure prevention, detection, evaluation and management released Monday by the American Heart Association. (
  • Determination of eligibility for blood pressure-lowering medication treatment is no longer based solely on blood pressure level, but now also considers cardiovascular disease risk level. (
  • Coronary heart disease (CHD) is a leading cause of death for men in the U.S. Both cardiorespiratory fitness (CRF) and the blood triglyceride/high-density lipoprotein ratio (TG:HDL ratio) are strong predictors of death from CHD. (
  • While it is still extremely important to measure traditional risk factors such as resting blood pressure, blood cholesterol, triglyceride, and glucose levels, having a measure or estimate of the patient's cardiorespiratory fitness level gives us additional information regarding cardiovascular disease risk,' explained Dr. Farrell. (
  • Higher ratios also indicate an increased risk of future prediabetes, type 2 diabetes, and cardiovascular disease. (
  • When used in combination with other risk factors, such as the patient's blood pressure, bloodwork, family history, etc., measuring or estimating the patient's level of CRF can result in a much more accurate determination of their cardiovascular disease risk status. (
  • They describe how measuring CRF in 6- to 10-year-olds and later in 8- to 12-year-olds can reveal indicators of increased cardiovascular disease (CVD) risk later in life. (
  • 1 Endothelial dysfunction is associated with a range of risk factors for cardiovascular disease, including hypercholesterolemia, 2,3 and some therapies that improve clinical outcome also reverse endothelial dysfunction. (
  • Look for the presence of other cardiovascular risk factor such as diabetes, hyperlipidaemia, smoking & family history of early onset cardiovascular disease. (
  • The patient may have a previous history of cardiovascular disease. (
  • This study examined the associations of blood pressure measured in the clinic (clinic blood pressure) and 24-hour ambulatory blood pressure with all-cause and cardiovascular mortality in a large cohort of patients in primary care. (
  • Results for cardiovascular mortality were similar to those for all-cause mortality. (
  • Ambulatory blood-pressure measurements were a stronger predictor of all-cause and cardiovascular mortality than clinic blood-pressure measurements. (
  • Increased risk of all-cause mortality is associated with nonoptimal blood pressure. (
  • 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. (
  • The relationship between blood pressure categories and all-cause mortality has not been fully addressed in cohort studies, especially in the general Chinese population. (
  • We analyzed the blood pressure-mortality relationship by using restricted cubic splines and Cox proportional-hazards regression analysis, estimating hazard ratios (HRs) and 95% confidence intervals (CIs). (
  • Nonoptimal blood pressure, which caused over 10 million deaths worldwide in 2016, is the leading cause of global mortality (1,2). (
  • Also, to our knowledge, no other general population-based studies have been made of the relationship between blood pressure categories and all-cause mortality in China except for 2 cohort studies, 1 of adults aged 40 or older and 1 of urban women (6,9). (
  • In addition, studies of Chinese adults that consider the potential sex difference in the blood pressure-mortality relationship are lacking (9,10). (
  • In addition, there is no direct and prospectively collected information available on the result of treatment of a "low" blood pressure on neonatal morbidity and mortality. (
  • Salt sensitivity of BP is a quantitative trait in which an increase in dietary sodium intake engenders an increase in BP .3,4 Salt sensitivity occurs in normotensive as well as hypertensive humans and predicts increased cardiovascular events and mortality, irrespective of unchallenged BP levels. (
  • Background Left ventricular hypertrophy has been established as an independent risk factor for the development of cardiovascular morbidity and mortality. (
  • 1 Obviously, management of patients with inflammatory arthritis focuses not on cardiovascular (CV) morbidity and mortality. (
  • Multivariate regression analyses show that age, the total cholesterol/HDL (high-density lipoprotein) ratio, glucose and BNP were independent predictors of endothelial function, and BNP remained an independent predictor ( P =0.009) in a binary logistic regression analysis using FBF (forearm blood flow) as a dichotomous variable based on the median value. (
  • High-growth segments of the market include whole blood glucose testing products for both personal and professional use, POC cardiac marker test kits and systems and POC coagulation monitoring systems. (
  • When he accompanied some colleagues to a session for free biometric screenings, Conti learned that his blood pressure and glucose levels were elevated. (
