The exponential fall of the pulmonary pressure curve from its systolic peak to left atrial pressure previously described in the presence of normal intraventricular conduction has been investigated in patients with right bundle-branch block. We have been able to show once more that the pulmonary artery diastolic pressure seeks the left atrial level: when right ventricular systole is delayed the ...

Acute pulmonary edema during hypertensive crisis has been attributed to acute left ventricular systolic failure secondary to increased afterload. We tested the hypothesis that the increase in coronary artery perfusion pressure associated with systemic hypertension could also contribute to increased left ventricular filling pressures by acutely increasing coronary intravascular volume and decrea...

objective: the aim of this study was to evaluate the effect of premenstrual syndrome (pms) treatment with selective serotonin reuptake inhibitor (ssri) on treatment response of refractory hypertension of the patients. method: this was a triple-blind randomized clinical trial conducted on female patients suffering from refractory hypertension and pms at the same time. we obtained informed consen...

The aim of this study was to verify the hypothesis that pulmonary artery (PA) distensibility may modify the pattern of right ventricular ejection. Pulmonary artery distensibility was evaluated with M-mode measurements of right pulmonary artery diameter from suprasternal notch simultaneous with pulmonary pressure measurements. Pulmonary artery pressure was measured in 19 subjects, 29 to 75 years...

introduction: world health organization (who) introduced hypertension as an epidemic in developing countries. however, hypertension is adequately controlled in only 12.5% of patients.  the aim of this study was to evaluate the relationship between ramadan fasting and mean arterial pressure (map). methods: this clinical, observational study was carried out at medical o.p.d of jinnah medical coll...

To determine their usefulness in estimating pulmonary artery pressure, left ventricular systolic time intervals (STI) were determined by echocardiography in 65 patients with dextro-transposition of the great arteries (TGA). The STI were measured from recordings of pulmonary valve motion at 100 mm/sec paper speed. The pre-ejection period (PEP) and the ratio of PEP to left ventricular ejection ti...

BACKGROUND Central pulse pressure, pulse pressure index and fractional pulse pressure have been confirmed to be associated with increased risk of cardiovascular disease, but if the severity of cardiovascular disease, specifically for the coronary artery disease, is evaluated by central systolic pressure and fractional diastolic pressure has been not well studied. AIMS This study was designed ...

background: the health promoting effects of green tea including anti-obesity and anti-inflammatory effects, decreasing heart attack risk and oxidative stress status has been widely demonstrated during the past decade. the purpose of this study was to determine the possible effects of green tea on the anthropometric indices, systolic and diastolic blood pressure in overweight and obese women. me...

background: hypertension is one of the prevalent and dangerous complications of diabetes mellitus. as it is difficult to control hypertension, the necessity of using new techniques such as non-pharmaceutical methods and complementary therapy is doubled. this study aimed to determine the effect of aerobic exercise on the blood pressure of patients with type 2 diabetes. methods: this study was a ...
