The effect of eight weeks of moderate-intensity endurance training on myocardial capillary density, ejection fraction and left ventricular shortening fraction in male rats with myocardial infarction
Background and objective: Vascular obstruction and impaired blood flow and oxygen delivery cause a myocardial infarction and limit a personchr('39')s function. Therefore, finding a way to create new arteries and replace blocked arteries has always been of interest to researchers, including exercise physiologists. Therefore, this study was conducted to evaluate the effect of eight weeks of moder...
متن کاملIntramural myocardial shortening in hypertensive left ventricular hypertrophy with normal pump function.
BACKGROUND In hypertensive left ventricular hypertrophy (LVH), intrinsic myocardial systolic function may be normal or depressed. Magnetic resonance tagging can depict intramural myocardial shortening in vivo. METHODS AND RESULTS Tagged left ventricular magnetic resonance images were obtained in 30 hypertensive subjects with LVH (mean LV mass index, 142 +/- 41 g/m) and normal ejection fractio...
متن کاملNormal Left Ventricular Ejection Fraction in Systemic
Ficuax 1. Two-dimensional echocardiogram stop frame images are shown above and accompanying schematics below. Left panel demonstrates an apical image with four heart chambers. Middle panel shows cloud of echoes from peripheral injection of normal saline solution demonstrating simultaneous appearance of echoes in all four chambers. A similar injection postoperatively demonstrates echoes in right...
متن کاملLeft Ventricular Function and Hypertrophy in Cardiomyopathy with Depressed Ejection Fraction By BOLLING
Left ventricular (LV) function and hypertro:hy, assessed during cardiac catheterization by quantitative biplane angiocardiography, were re'ated to posteatheterization course in 36 patients found to have cardiomyopathy with depressed eject.on fraction (EF). EF ranged from 0.09 to 0.41, LV mass (M) from 99 to 317 g/m2, LV end-diastolic volume (V) from 104 to 347 ml/m2, and ratio of M/V from 0.66 ...
