The present communication is based on an examination of 33 cases with dilated cardiomyopathy and 48 with severe myocarditis. Nine patients with dilated cardiomyopathy were diagnosed as having developed cardiogenic shock. ⋯ Cardiogenic shock in dilated cardiomyopathy was demonstrated to be characterized by a progressive decrease in cardiac contractility, no increase in peripheral vascular resistance, and high pulmonary hypertension. Profound cardiomyocyte alterations followed by increased fibrosis of intermuscular and perivascular spaces contribute to the development of cardiogenic shock in dilated cardiomyopathy.

Calcified aortic valves were detected in 109 patients studied in hospital by an echocardiographic method (2D- and M-scanning). It was found that, unlike rheumatism, calcification starting in the aortic annulus and semilunar bases might result in formation of degenerative (non-inflammatory) calcific aortic stenosis. ⋯ The authors defined clinical and echocardiographic differentially diagnostic criteria for degenerative (non-inflammatory) and rheumatic (inflammatory) calcific aortic stenosis. They also discussed pathogenetic aspects of aortic valve calcification and problems of terminology.
