[Clinical value of allele variants of cytochrome CYP2C9 gene for anticoagulation therapy with warfarin].
Warfarin is metabolized by cytochrome CYP2C9 and its pharmacokinetic properties depend on structural polymorphisms of CYP2C9 gene. We studied frequencies of allele variants of CYP2C9 gene and associations of individual reaction to warfarin intake with genotype of CYP2C9 gene. Population frequencies of CYP2C9x1, CYP...

[Antioxidant properties of statins].
Statins block expression of protein subunits of Gi-proteins (p22phox and gp91phox) which determine oxidase activity of NADPH oxidases and expression of GTP-ase (NADPH activator). This leads to suppression of activity of prooxidant enzyme systems (NADPH oxidase, xanthine oxidase, oxidase activity of endothelial NO-s...

[The place of cardiac glycosides in the treatment of chronic heart failure].
In a series of papers the authors analyze literature data on the use of cardiac glycosides for long term treatment of chronic heart failure. Part 1 is devoted to clinical pharmacology of glycosides with special emphasis on digoxin. In low doses digoxin produces no substantial effect on contractility of left ventric...

[Is it necessary to detect insulin resistance for diagnosis of metabolic syndrome in clinical practice?].
Metabolic syndrome is widely spread in population especially among subjects with risk factors of atherosclerosis related diseases. Since 1988 criteria of metabolic syndrome have undergone substantial transformation. Technical difficulties related to detection of insulin resistance created obstacles to application o...

[Evolution of atherosclerosis of the aorta and coronary arteries in practically healthy men in Moscow for a 40-year period].
AIM: To assess 40 years evolution of atherosclerosis of the aorta and coronary arteries among practically healthy Moscow men. METHODS: We compared results of 2 studies of prevalence and extent (area) of atherosclerotic lesions in thoracic and abdominal aorta and 2 main coronary arteries. The studies were conducted i...

[The use of esmolol in patients with myocardial infarction complicated with acute left ventricular failure].
Forty patients with acute Q-wave myocardial infarction and Killip class I-II heart failure were randomized to treatment with esmolol (n=22) or just to standard therapy (n=18) and followed up for 30 days. Esmolol treated patients had significantly lower in-hospital mortality (p<0.02), less frequently had postinfarct...
