| Abstract: | The examination was conducted in 142 patients with coronary atherosclerosis, aged 33 to 74 years, and in 40 normal persons, aged 25 to 48 years. The pain form of the disease was observed in 96 patients, the arrhythmic one--in 38, the painless one--in 8 patients. The arterial pressure was within the normal limits in the examined patients. In 67.6% of the patients hypercholesterolemia was diagnosed, in 47.3%--hypertriglyceridemia. Type II hyperlipoproteinemia was found in 67.6% of the cases, types III and IV--in 5.3 and 9.1%, respectively, type V--in 0.5% of the patients; the type of hyperlipoproteinemia could not be identified in 10.6%, and in 6.9% of the cases the blood level of lipoproteins did not differ from the normal. The plasma renin activity examined by the radioimmunoassay in normals comprised 1.26 +/- 0.21 ng/ml/hour; in patients with the pain form of coronary atherosclerosis--6.67 +/- 0.72 ng/ml/hour; in those with arrhythmias--6.89 +/- 1.20 ng/ml/hour; in those with the painless form--2.39 +/- 1.02 ng/ml/hour. The highest renin activity was revealed in types IIa, IIb and III hyperlipoproteinemia, as well as in paroxysmal arrhythmia and cardiac fibrillation. |
