Mitral valve echocardiograms recorded in 57 patients revealed spontaneous ventricular premature contractions in 46 and supraventricular premature contractions in 11. The latter patients had normal mitral valve motion. Five patterns of mitral valve mo

To define the incidence of mitral regurgitation (MR) and elucidate its potential contribution to the development of severe congestive heart failure after acute myocardial infarction (AMI), Doppler echocardiograms were obtained within 48 hours of onse

Twenty-one patients with polymyositis were prospectively examined with echocardiography, phonocardiography and electrocardiography. Cardiac performance, estimated with echocardiography, was enhanced as shown by a significant (P less than 0.01) increa

The mechanism whereby aging, in the absence of cardiac disease, may alter the pattern of left ventricular (LV) diastolic filling is unknown. Accordingly, this study was designed to examine the factors that may be in part responsible for aging's effec

Coronary hemodynamics and vasodilatory effects on major epicardial arteries were investigated after a single dose of nicorandil in 22 patients undergoing cardiac catheterization for suspected coronary artery disease. Nicorandil, 20 mg, was administer
