Abstract
Human heart muscle proteins have been analyzed by two-dimensional electrophoresis. Twenty five autopsy heart muscle samples obtained from individuals who had died in accidents and who had no signs of cardiovascular pathology have been compared with biopsy and autopsy myocardium samples of patients with: dilated cardiomyopathy (5 cases), hypertrophical cardiomyopathy (2 cases) and myocarditis (2 cases). In dilated cardiomyopathy in 3 out of 5 cases an additional protein spot was found in the myocardial myosin light chain 1 area.
