Особенности липидного обмена и некоторые генетические маркеры при стрессорной кардиомиопатии

Особенности липидного обмена и некоторые генетические маркеры при стрессорной кардиомиопатии

Abstract

The results of the investigation of the main indicators of blood serum cholesterol metabolism (such as: total cholesterol, LDL/HDL ratio, LDL, triglycerides) and several genetic markers associated with the early development of atherosclerosis (MTHFR gene, ApoE gene) in engine-drivers with stress cardiomyopathy are presented. Patients with stress cardiomyopathy show more frequent availability of T-allele of MTHFR gene compared with healthy male population of St-Petersburg. It was revealed The increase of the total cholesterol level and LDL/HDL ratio in patients with the signs of stress cardiomyopathy is revealed. Our data demonstrate the association between ApoE*4 allele with increased levels of total cholesterol and LDL fraction of blood serum, and the association between ApoE*2 allele with increased level of triglycerides as well. Results: Therefore, hyperhomocysteinemia associated with C677T polymorphism MTHFR gene might take part in developing stress cardiomyopathy. So E*2/E*3/E*4 polymorphism ApoE gene might take part in forming atherosclerotic alterations in persons subjected to stress. Key words: stress cardiomyopathy, engine-drivers, cholesterol, low-density lipoproteins, methylenetetrahydrofolate reductase gene, apolipoprotein E gene.

Представлены результаты исследования основных показателей липидного обмена сыворотки крови (общий холестерин, коэффициент атерогенности, липопротеиды низкой плотности, триглицериды) и некоторых генетических маркеров, ассоциирующихся с ранним развитием атеросклероза (ген метилентетрагидрофолатредуктазы и ген аполипопротеина Е) у машинистов железнодорожного транспорта со стрессорной кардиомиопатией. У лиц с признаками стрессорных повреждений сердца показана более частая, чем в здоровой мужской популяции, встречаемость аллеля Т гена MTHFR. Выявлено увеличение уровня общего холестерина и коэффициента атерогенности в группе пациентов со стрессорной кардиомиопатией. Показана ассоциация полиморфного варианта Е4 гена АроЕ с увеличением уровня общего холестерина и липопротеидов низкой плотности сыворотки крови, а также ассоциация полиморфного варианта Е2 гена АроЕ с увеличением уровня триглицеридов сыворотки крови. Результаты указывают на возможность участия в развитии стрессорной кардиомиопатии гипергомоцистеинемии, ассоциированной с С677Т полиморфизмом гена MTHFR. Нельзя исключить роли гена АроЕ в развитии атерогенных сдвигов у лиц, подверженных воздействию стресса.
