OBJECTIVE to establish the mean and normal range for the difference in simultaneous systolic and diastolic blood pressure measurements between the right and left arm. SUBJECTS 462 subjects, age range 20-89 years, in sinus rhythm and with no history of stroke, 98 of whom had a history of cardiovascular disease or were taking vasoactive medication. METHODS four simultaneous recordings of bloo...

WALLACE, ANDREW G., N. SHELDON SKINNER, JR., AND JERE H. MITCHELL. Hemodynamic determinants of the maximal rate of rise of left ventricular pressure. Am, J. Physiol. 205 (I) : 30-36. 1963. -The maximal rate of left ventricular pressure development (max. dp/dt) was measured in an arenexic preparation which permitted independent control of stroke volume, heart rate, and aortic pressure. Max. dp/d...

In 16 patients with hypertrophic cardiomyopathy, an acute response of the left ventricular end-diastolic pressure and volume index to intravenously administered verapamil was assessed. Verapamil decreased the left ventricular end-diastolic pressure from 20 +/- 6 to 17 +/- 5 mm Hg(p less than 0.001) and increased the end-diastolic volume index from 82 +/- 22 to 91 +/- 23 ml/sqm (p less than 0.01...

To obtain blood pressure distribution for Iranian children, we assessed 10,288 students aged 6-13 years (4871 boys and 5417 girls) in Tehran. Mean systolic and diastolic blood pressure showed incremental increases with age, weight and height in both sexes. Mean increases in systolic blood pressure for boys and girls were 1.7 and 0.8 mmHg per year respectively and for diastolic blood pressure we...

OBJECTIVE To evaluate the diastolic function after regression of left ventricular hypertrophy, in mild to moderate hypertension treated with angiotensin converting enzyme(ACE) inhibitor and, if necessary, with a diuretic. METHODS Ninety-eight hypertensive patients with left ventricular hypertrophy (LVH) and abnormal left ventricle diastolic function indexes received captopril (Capotena) 50 to...

The relationship between blood pressure, ponderal index, sex, blood glucose, haemoglobin, serum uric acid, calcium cholesterol and creatinine, and albumin has been examined in 698 subjects aged between 44 and 49 years from the register of a group general practice. Sixty per cent of the variation in systolic pressure could be explained by statistically significant associations with diastolic pre...

Pericardial pressure was measured in 18 patients undergoing cardiopulmonary bypass for up to 10 days using a solid state transducer. Mean and phasic pericardial pressure wave forms were similar to those reported in animals. A wide range of mean pressure from 0 to 30 mmHg was recorded, and values of up to 20 mmHg were observed in patients whose postoperative clinical course was uncomplicated. Fl...

Background & Aims: Endothelin_1 secreted by endothelial cells has been identified as the strongest vascular constrictor. The aim of the present study was to investigate the role of concurrent training on plasma concentration of endothelin_1 and its relationship with blood pressure of old women. Methods: A total of 20 menopause women (Mean age: 67.47±5.92 years, mean body length: 152.92±7.52cm, ...

In Western populations, mean systolic and diastolic blood pressures rise with advancing age up to the sixth decade of life, whereupon systolic blood pressure continues to increase and diastolic pressure starts to decline. The ensuing widening of pulse pressure is mainly ascribed to stiffening of the arterial vasculature. When hypertension is defined as systolic blood pressure of at least 140 mm...

Diastolic function is a major determinant of ventricular performance, especially when loading conditions are altered. We evaluated biventricular diastolic function in lambs and studied possible load dependence of diastolic parameters [minimum first derivative of pressure vs. time (dP/dt(min)) and time constant of isovolumic relaxation (tau)] in normal (n = 5) and chronic right ventricular (RV) ...
