Echocardiography was used to measure right ventricular systolic time intervals (RVSTI) in 85 normal children (group I) and in 229 patients undergoing cardiac catheterization (group II). Corrected right ventricular pre-ejection period (RPEPC) and right ventricular ejection time (RVETc) (based on regression analysis of group I) and RPEP/RVET were each correlated with pulmonary artery (PA) diastol...

this is a 9uasi experimental study to compare blood pressure measurements taken by both components of stethoscope, bell and diaphragm. blood pressure was evaluated in fifty patients of fifteen years of age and older. equal populations of both genders were selected randomly from infectious, surgery and internal medicine wards. subjects with cardiac arrhythmia weren't included in the study. ...

introduction pulmonary hypertension is common among patients with hyperthyroidism, and graves’ disease constitutes the most common cause of thyrotoxicosis. case presentation we report the case of a female patient admitted to the cardiology department with shortness of breath and pretibial myxedema. the diagnostic work-up revealed combined pre- and post-capillary pulmonary hypertension due to gr...

OBJECTIVE To determine whether an abnormal response of diastolic blood pressure during treadmill exercise stress testing correlated with the number of obstructed vessels and with left ventricular systolic function in patients with coronary artery disease. DESIGN Diastolic blood pressure was measured invasively during exercise stress testing and coronary angiograms and left ventriculograms wer...

BACKGROUND Because coronary perfusion occurs mainly during diastole, patients with coronary artery disease (CAD) could be at increased risk for coronary events if diastolic pressure falls below critical levels. OBJECTIVE To determine whether low blood pressure could be associated with excess mortality and morbidity in this population. DESIGN A secondary analysis of data from the Internation...

BACKGROUND Low-gradient severe aortic stenosis with preserved ejection fraction is an increasingly recognized entity, and symptomatic patients may benefit from aortic valve replacement. However, systemic hypertension frequently coexists with low-gradient severe aortic stenosis, which itself may cause elevated left ventricular (LV) filling pressures with resultant symptoms of dyspnea. METHODS ...

Background: Brain ischemic disorders are common diseases of neural systems. One of the predisposing factors affect to the brain ischemia is systemic hypertension. The aim of this study was the determination of relation between blood pressure and spread of brain ischemia in CT scan in brain ischemia patients. Materials & Methods: In the first stage and on the basis of research group, we selecte...

objective: to find out the effect of physical activities and obesity among ramadan fasting hypertensive patients of karachi. methods: 117 hypertensive patients were selected conveniently from the staff and faculty members of dow university and other locations of karachi. the inclusion criterion was the hypertensive patients with at least 20 days of fasting. the investigators visited three times...

OBJECTIVES This study sought to present evidence that short stature is a hemodynamic liability, which could explain in part the inverse relation between body height and cardiovascular risk. BACKGROUND Other explanations for the association of short stature with increased cardiovascular risk include advancing age, reduced pulmonary function, genetic factors, poor childhood nutrition and small-...
