[Effect of peripheral vasodilators on the local contractile function of the myocardium in patients with post-infarction cardiosclerosis].

Echocardiography was used to explore regional myocardial contractility in 92 patients with postinfarction cardiosclerosis complicated by heart failure developed in the late postinfarction period. All the patients were shown to display regional myocardial contractile dysfunctions as hypo-, a-, and dyskinesia accompanied with hyperfunction of intact myocardial segments. The most severe asynergy was present in anterior postinfarction scars. Peripheral vasodilators were found to improve contractility in the hypokinetic and intact areas of the myocardium.
