background: hypertension is a risk factor for many diseases. nutritional methods are considered as major tools in lifestyle modification for lowering blood pressure. the present study was conducted to determine the level of dietary adherence in hypertensive patients. methods: this descriptive-analytical study was performed in 2015, on hypertensive patients who were referred to heart clinic of s...

The purpose of this study is to investigate the effect of the long-term aerobic exercises on cardiac structure, left ventricular stroke volume, and cardiac output. To achieve the purpose of the study, a total of 22 volunteers-including 10 people who have continued regular exercises and 12 people as the control group-were selected as subjects. With regard to data processing, the IBM SPSS Statist...

A beneficial effect of verapamil on left ventricular relaxation has been reported in patients with hypertrophic cardiomyopathy. The effect of 0.1 mg/kg intravenous verapamil on left ventricular relaxation and diastolic mechanics was studied in 10 patients with hypertrophic cardiomyopathy and 13 patients with aortic stenosis. M mode echocardiograms and left ventricular high-fidelity pressure mea...

OBJECTIVE We evaluated the influence of the diameter and the preparation of the pilot hole on the resistance to the pulling out and the strength when inserting pedicle screws with conical internal diameter. METHODS Mechanical experiments were performed with pedicle conical screws of 4.2 mm and 5.2 mm diameter. They were inserted in the vertebral pedicles of swine. The hole was manufactured wi...

BACKGROUND Echocardiographic screening of families with dilated cardiomyopathy has identified a subgroup of asymptomatic relatives with left ventricular enlargement (LVE). The prognostic significance of LVE in this setting is incompletely understood. METHODS AND RESULTS We evaluated 457 asymptomatic relatives in 128 dilated cardiomyopathy families and identified 110 individuals (24%) with LVE...

background : the signal-averaged electrocardiography is a noninvasive method to evaluate the presence of the potentials generated by tissues activated later than their usual timing in the cardiac cycle. the purpose of this study was to demonstrate the correlation between the filtered qrs duration obtained via the signal-averaged electrocardiography and left ventricular dimensions and volumes an...

BACKGROUND AND PURPOSE Few studies have examined the early effects of statins on carotid artery elasticity, a potential surrogate marker of cardiovascular risk. This study examined the short-term effects of atorvastatin 80 mg daily on carotid elasticity measured by high-resolution B-mode ultrasound. METHODS The study included 40 stroke-free and statin-naive subjects older than age 45 (mean ag...

was recorded simultaneously with pulsed Doppler echocardiography of left ventricular inflow and M-mode echocardiography of left ventricular diameter. Chamber stilfness constants, kd and k1, were obtained from the diastolic pressure-diameter and pressure-volume relations, respectively. Relaxation was measured by the isovolumic relaxation time constants, TL and TD, derived from the exponential le...
