[Clinical significance of mitral valve insufficiency detected by Doppler echocardiography in acute myocardial infarction].
Doppler echocardiography revealed in the third week of the recent myocardial infarction a pattern of mitral insufficiency in 27 (36%) of the 75 patients studied. Mitral insufficiency was usually associated with the more severe clinical course of myocardial infarction, with more frequent supraventricular and ventricular arrhythmias, heart failure, and with more extensive infarction area, as compared with the patients without mitral failure. A decreased contractibility of the left ventricle wall (especially in patients with anterior myocardial infarction accompanied by mitral insufficiency and enlargement ventricular dimension) may suggest its role in the development of mitral insufficiency in myocardial infarction. The results show the need of Doppler echocardiography in recent myocardial infarction to detect patients with an increased risk.
