The relations of Metropolitan Life Insurance Co. Relative Weight values and blood pressure (BP) to minimal forearm vascular resistance, ventricular septal and posterior wall thickness, left ventricular (LV) mass index and cardiac diastolic function were assessed in 31 men, 37 +/- 2 (mean +/- standard error of the mean) years of age. Eighteen patients with untreated mild hypertension were compar...

background: severe and prolonged physical training is associated with morphological and physiological cardiac changes, often termed as the “athlete’s heart”. echocardiographic features peculiar to elite iranian athletes have not been previously described. the aim was to examine the echocardiographic characteristics of highly trained iranian athletes involved in three different sports.   methods...

controversy exists regarding cavity preparation for restoration of interproximal caries in posterior teeth in terms of preserving the tooth structure and suitable stress distribution. this study aimed to assess the effect of extension and type of class ii cavities and the remaining tooth structure in maxillary premolars restored with composite resin on the biomechanical properties of teeth usin...

INTRODUCTION Epicardial fat volume (EFV) has been reported to correlate with the severity of coronary artery disease (CAD). Pericardial fat volume (PFV) has recently been reported to be strongly associated with CAD severity and presence. We aimed to investigate the relationship between EFV and PFV with severity of coronary artery stenosis in patients undergoing 64-slice multi-slice computed tom...

To assess the contractile state of the hypertrophied ventricle induced by long-standing systemic hypertension in 22 patients, we used echocardiography for the measurement of the ventricular diameter and posterior wall thickness, together with simultaneous recording of brachial arterial pressure. Meridional wall stress (WSt) was used for the expression of the force per unit cross-sectional area....

The left ventricular diastolic pressure-volume.relationship shifts upward during angina, but why this happens is not known. To assess regional myocardial stiffness, we studied 12 patients who.had coronary artery disease using simultaneous left ventricular micromanometer pressure recording and Mmode echocardiography before and during angina induced. by pacing tachycardia. All patients had twoor ...

conclusions our results demonstrated the ability of pw-tdi and s/sr modalities in detection of the early subclinical abnormalities in asymptomatic patients with significant chronic ar. results ar group had significantly increased lv end systolic and end diastolic volumes, interventricular septum and posterior wall thickness compared to controls. in ar, sm and em of septal wall, sm of lateral wa...

Background: Conventional fixation methods of posterior wall acetabular fractures feature the use of plating and lagscrews. However, fixation of posterior wall fractures with buttress plating alone offers potential advantages by avoidingthe hardware complications related to hardware placement through the wall fragment. The purpose of this study wasto examine if buttress plating...
