The purpose of the study was to determine the effect of transient changes in intrathoracic pressure on systemic arterial pressure by utilizing hiccups as a tool. Values of systolic and diastolic pressures before, during, and after hiccups were determined in 10 intubated preterm infants. Early-systolic hiccups decreased systolic blood pressure significantly (P < 0.05) compared with control (39.3...

The physiological adaptation to the erect posture involves integrated neural and cardiovascular responses that might be determined by genetic factors. We examined the familial- and individual-specific components of variance for postural changes in systolic and diastolic blood pressure in 767 volunteer nuclear adult families from the Victorian Family Heart Study. In 274 adult sibling pairs, we m...

BACKGROUND Mean systolic blood pressure in apparently healthy cats has been reported as approximately 125 mmHg using direct assessment, but there is greater variability in reported values using indirect assessment. Increasing age and the white-coat effect are associated with increased systolic blood pressure. HYPOTHESIS/OBJECTIVES To report Doppler-derived blood pressure measurements from a l...

Aims: The present study was conducted with the aim of determining the effect of passive movements on hemodynamic parameters, including systolic blood pressure, diastolic blood pressure, mean arterial pressure, pulse, and pulse pressure of patients under ventilation. Materials & Method: In this controlled clinical trial, 64 patients under ventilation in Kohgiluyeh and Boyer-Ahmad University of ...

Ejection has previously been thought to exert only negative effects on end-systolic left ventricular pressure, via mechanisms like shortening deactivation and the force-velocity relation. Whether ejection also exerted a positive influence on pressure generation was tested by comparing two successive beats: 1) the last beat of steady-state ejection versus 2) a totally isovolumic contraction at t...

Arterial stiffening is the principal cause of increasing systolic pressure with advancing years and in patients with arterial hypertension. It is associated with progressive arterial dilation and is due to degeneration of the arterial wall, probably as a consequence of repetitive cyclic stress; it increases systolic pressure directly by increasing amplitude of the pressure wave generated by a g...

BACKGROUND Studies have shown sodium restriction to have a beneficial effect on blood pressure (BP) of hypertensive patients. OBJECTIVE To evaluate the impact of light salt substitution for regular salt on BP of hypertensive patients. METHODS Uncontrolled hypertensive patients of both sexes, 20 to 65 years-old, on stable doses of antihypertensive drugs were randomized into Intervention Grou...

This study aimed to investigate the association between sleeping pill use and hypertension or blood pressure (BP) via a cross-sectional analysis.A total of 11,225 subjects (5875 men and 5350 women) underwent health examinations. We compared the proportion of sleeping pill users among hypertension (n = 5099) and normotensive (n = 6126) participants. We analyzed participants with no intake of ant...

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...
