BACKGROUND Still today, measurements used as a reference in the cardiac magnetic resonance imaging have been obtained mainly from studies carried out in North-American and European populations. OBJECTIVE To obtain measurements of the diastolic diameter, systolic diameter, end diastolic volume, end systolic volume, ejection fraction, and myocardial mass of the left and right ventricles in Braz...

Purpose: Arterial stiffness has been shown as an independent predictor of cardiovascular and all-cause mortality in hypertensive patients. commonly seen pulse wave Doppler echocardiographic examination the left ventricle outflow tract, is related to diastolic dysfunction arterial parameters. Our study aims investigate relation between aortic distensibility (AD) presystolic A (PSW),.

The purpose of this investigation was to assess the interactive influence of sympathetic activation and supplemental nitric oxide (NO) on brachial artery distensibility vs. its diameter. It was hypothesized that 1) sympathetic activation and NO competitively impact muscular conduit artery (brachial artery) mechanics, and 2) neurogenic constrictor input affects conduit vessel stiffness independe...

Background: To assess the cardiac functions in patients with chronic kidney disease (CKD).Methods: 150 CKD were randomly selected. 12 lead ECG performed to detect CVD. All Patients diagnosed CKD. The left ventricular ejection fraction (LVEF) and fractional shortening (FS) taken as measures of LV systolic function. Diastolic function was determined by measuring early late peak velocities (E/A) r...

Myocardial ischemia (MI) is one of the leading causes of death, while Qishen Yiqi Drop Pill (QYDP) is a representative traditional Chinese medicine to treat this disease. Unveiling the pharmacological mechanism of QYDP will provide a great opportunity to promote the development of novel drugs to treat MI. 64 male Sprague-Dawley (SD) rats were divided into four groups: MI model group, sham opera...

The purpose of this study was to compare the echocardiographic features of Irish wolfhounds with clinically inapparent dilated cardiomyopathy (DCM) (n = 33) to dogs with advanced DCM (n = 33) and to normal dogs (n = 262). Significant differences were detected between the three groups. In dogs with DCM, the most sensitive diagnostic measurements were: end-systolic volume index (ESVI), E-point to...

The instantaneous transverse diameter of the left atrium, left ventricular free wall segment length (SEG), and the long axis of the anterior papillary muscle (APM) length were measured throughout the cardiac cycle, using ultrasonic dimension gauges together with left atrial and left ventricular pressures in 12 open-chest dogs. During atrial contraction, left atrial diameter decreased from 19.7 ...

Cardiac dimensions and left ventricular function were investigated at rest with non-invasive methods in 14 professional road race cyclists and in 11 age-matched sedentary control subjects. The electrocardiographic findings were in agreement with previous studies in endurance athletes and the vectocardiographic data showed anterior displacement of the electrical forces. Echocardiographic dimensi...
