Correlation among radiologic, echocardiographic indices and self paced-exercise capacity in heart failure

"Echocardiography in Nigeria: use, problems, reproducibility and potentials"

“…The potential of echocardiography as a research tool in Nigeria cannot be overemphasized. Studies emanating from the country have focused on the common cardiovascular diseases in the country such as hypertensive heart disease [ 7 - 15 ], heart failure[ 16 , 17 ], dilated cardiomyopathy including peripartal heart disease, and valvular heart disease[ 18 , 19 ]. Others have also studied cardiac function in diabetes mellitus[ 20 - 22 ], congenital heart diseases[ 23 ] and sickle cell disease[ 24 ].…”

Reply to the letter “Androgens in cardiac fibrosis and other cardiovascular mechanisms”

“…However, these two studies did not evaluate patients' myocardial diastolic function. Exercise capacity is highly correlated with myocardial diastolic function [11], and myocardial fibrosis is highly associated with diastolic dysfunction in patients with heart failure [12]. Physiological level of testosterone has been proven to ameliorate cardiac dysfunction and to attenuate myocardial fibrosis [13].…”
