Relation of plasma lipoprotein(a) to infarct artery patency in survivors of myocardial infarction.

abstract：BACKGROUND:Few data exist regarding the effects of angiotensin converting enzyme inhibitors in patients with regurgitant valvular lesions. We postulated an immediate improvement in cardiac performance with captopril in mitral regurgitation, which, in a hemodynamically compensated group of patients, might be mediated th...
