title: [Effect of cytoprotection on the oxidative processes and endothelial function in elderly patients with ischemic heart disease].
abstract: The aim of the study was to investigate the effects of cytoprotectional drug Mildronate ("Grindex", Latvia) on some parameters of oxidative processes and endothelial function in elderly patients with coronary heart disease (CHD). One hundred seventeen elderly CHD patients were included into controlled study. The criteria to include the patients into the study were: men and women upwards 60 years old with CHD, with heart failure FC II or III (in accord, NYHA classification), with arterial hypertension (AH), without diabetes mellitus. All patients were randomized into 2 groups: 1) 67 patients 75.4 +/- 0.5 years old were treated with Mildronate 500 mg/day against traditional basal therapy during 12 weeks (the main group) and 2) 50 patients 74.0 +/- 0.6 years old were treated only traditional basal therapy during 12 weeks (the compare group). The blood lipid profile parameters, such as total cholesterol (CH), triglycerides (TG), low density lipoprotein cholesterol (LDL-CH), high density lipoprotein CH (HDL-CH), LDL antioxidant potential (concentration of alpha-tocopherol and retinol in LDL), initial level of lipid peroxidation (LPO) products in LDL, LDL resistance to oxidation in vitro and the blood level of NO metabolites were evaluated before and after 4 and 12 weeks of the study. Effect of Mildronate on the blood lipid profile parameters in elderly CHD patients was not revealed. The initial level of LPO products in LDL was decreased and LDL resistance to oxidation in vitro was increased in main group patients after 12 weeks of study in comparison with the same parameters before the study and with compare group patients (p < 0.05). The blood level of NO metabolites was 1.5-fold higher in main group patients after 12 weeks of study in comparison with the same parameters before the study and with compare group patients (p < 0.05). Thus, in elderly CHD patients the several antiatherogenic effects of Mildronate, such as the decreasing activity of LPO processes in LDL and the increasing synthesis/secretion of blood NO, were revealed.
