[Status of the contractile function of the myocardium in patients with a mild form of infectious-allergic myocarditis]. / Sostoianie sokratitel'noi funktsii miokarda u bol'nykh s netiazheloi formoi infektsionno-allergicheskogo miokardita.

ABSTRACT

The authors analysed the results of echocardiography of patients with a mild ("ambulatory") form of infectious allergic myocarditis (the 1st group). Enhanced myocardial contractility was revealed in the 1st group as compared to the group of healthy persons (controls), decreased left ventricular contractility was noted in patients of the 2nd group (with dilated cardiomyopathy). A conclusion was made that a mild form of infectious allergic myocarditis was characterized by enhanced left ventricular contractility as a sign of its compensatory hyperfunction in response to myocardial damage.
