[Age-related sarcopenia as the risk factor of development of myocardial dysfunction and chronic heart failure in elderly patients with arterial hypertension].

To estimate the expressiveness of involutive sarcopenia and its influences on the development of myocardial dysfunctions 88 patients of 60+ years with arterial hypertension (AH) II stage (middle age 66.9 +/- 0.7 years, 76 women and 12 men) and 32 persons who do not have cardiovascular diseases were surveyed. It is revealed that expressiveness of involutive sarcopenia is non-uniform at senior patients; structural and functional changes of heart in elderly patients with AH clinically shown by myocardial dysfunction, decreased tolerance to physical activity, are more pronounced in the group of patients with a low index of muscular weight. High values of the indicators of oxidative modification of lipids in the blood serum and the insufficiency of mechanisms of antioxidant protection in elderly patients with AH who have low index of muscle mass point to the negative role of oxidative stress in the pathogenesis of involutive sarcopenia.
