[Biochemical measures in cardiac patients: an analysis of change during rehabilitation (author's transl)].

210 male patients hospitalized for cardiac rehabilitation have been studied. As a result of age matching the sample was reduced to 190 patients: 72 patients with myocardial infarction, 90 patients with functional cardiovascular diseases, and 28 patients with angina pectoris. At the beginning and at the end of the 4 to 6 week rehabilitation program total lipids, cholesterol, triglycerides, phosphatides, GOT, GPT, LDH, HBDH, cholinesterase, aldolase, blood sugar, creatinine, electrolytes, hemoglobin, erythrocytes, leukozytes, and catecholamines were measured. In addition to the statistical comparison of the three groups and their specific change patterns, effects of body weight reduction and improvement of physical fitness were analyzed. The decrease of lipids is especially associated with weight reduction, whereas the decrease of enzyme activity and electrolyte concentration is accompanied as well with weight reduction as with the improvement of physical fitness.
