title: [Electrocardiographic and echocardiographic evaluation of cardiac changes in systemic scleroderma].
abstract: Cardiac abnormalities were studied using the clinical, electrocardiographic and echocardiographic methods in 66 patients with systemic scleroderma. Abnormal ecg was seen in 41 patients (62.1%), most frequently in form ventricular extrasystole (21.2%), incomplete block of the right bundle branch (12.1%), left ventricular and right atrial hypertrophy (10.6%) each, and the pattern suggesting the history of past myocardial infarction (7.6%). Abnormal echocardiographic results were found in 38 patients (57.6%). The most usual changes, differentiating that group from the controls, were: sluggish diastolic movement of the posterior wall of the left ventricle (40.7%), pericardial effusion (37.0%), elongation of the isovolumic relaxation time diastole phase (99.3 s.m.v. 81.1 ms, p less than 0.001) and right ventricular dilatation. There were no significant differences between the scleroderma and the control group as regards the indices of the contractility of the left ventricle: ejection fraction (EF), velocity of circumferential fibres shortening (VCF), diastolic size of the left ventricle and of the left atrium. The prevalence of the electrocardiographic and echocardiographic abnormalities in particular types of scleroderma (diffuse, acroscleroderma, severe acroscleroderma, CREST) was roughly similar: 50-76%. Finding of the impaired diastolic rather than systolic function of the left ventricle and of the similar prevalence of the cardiac abnormalities in the particular types of scleroderma is new and contradictory to the commonplace opinions.
