[Combination treatment with coenzyme Q10 and simvastatin in patients with coronary atherosclerosis].

In order to assess efficacy of one of natural antioxidants--coenzyme Q10 (90 mg daily) and its combination with simvastatin (10 mg daily) 44 outpatients with coronary atherosclerosis were examined. Twenty four patients had undergone coronary artery bypass surgery, 12--coronary angioplasty and in 8 coronary heart disease was confirmed by angiography. Duration of treatment was 12 weeks. Positive effects of coenzyme Q10 was particularly expressed in relation to antiatherogenic fraction of cholesterol which increased by 23%. Index of atherogenicity decreased by 27%. At the background of coenzyme Q10 treatment 30% reduction in plasma lipoperoxide levels occurred demonstrating potentially independent role of coenzyme Q10 in positive modification of oxidative stress. Coenzyme Q10 revealed antiaggregatory ability. It was not related to the improvement of endothelial function. Normalization of plasma nitric oxide concentrations was achieved only with combination of coenzyme Q10 and simvastatin. This fact may be explained by positive action of statins on endothelial function.

Intravascular laser therapy of acute myocardial infarction.

The efficacy of a new method of treatment, endovascular blood irradiation with He-Ne laser, developed by the authors, was studied in 295 patients with primary acute transmural myocardial infarction (MI). Twenty-four-hour Holter monitoring findings before and after laser irradiation suggested the possibility of preventing sudden death in the acute period of MI owing to the high anti-arrhythmic efficacy of the method with respect to high-grade ventricular arrhythmias. Precodial ECG mapping and serial determination of blood enzyme activities (CPK and MB-CPK) showed that irradiation performed within the first hours of MI development contributed to effective limitation of the infarction area and restricted the spread of the area of myocardial ischemic damage.

In 80 patients with acute transmural myocardial infarction (30 patients with anterior infarction and 50 with posterior infarction), endovascular irradiation of blood with helium-neon laser was studied for effects on the time-course of the processes of ischemic lesion and myocardial necrotization from the data on precordial mapping of 35 leads ECG (epsilon ST, nST, nQS) and serum creatinine phosphokinase and its MB fraction (maximal activity peak attainment time, level normalization, summary Q ejection and activity increase rate, delta E/delta t) were measured. The irradiation initiated no later than 4 hours after the development of anginal pains was found to contribute to a more rapid formation of a necrotic zone and to a decrease in extension and relapses of myocardial infarction.
