镁是人体内多种酶的激活剂。镁能阻止或者延缓动脉粥样硬化的发生及发展 ,能通过抑制钙内流、抗氧化、抗血小板活化和保护内皮功能等途径防止缺血再灌注损伤。流行病学研究表明 ,镁与冠心病的发病率和死亡率相关。临床研究提示 ,镁能明显改善冠心病病人的生活质量 ,减少心绞痛的发生及提高运动耐量。在急性心肌梗塞时 ,如果早期小剂量较长时间使用镁治疗 ,病人能得到一定的益处。 Magnesium is a multi-enzyme activator in the human body. Magnesium can prevent or delay the occurrence and development of atherosclerosis, and can prevent ischemia-reperfusion injury by inhibiting calcium influx, anti-oxidation, anti-platelet activation and protection of endothelial function. Epidemiological studies have shown that magnesium is associated with morbidity and mortality of coronary heart disease. Clinical studies suggest that magnesium can significantly improve the quality of life of patients with coronary heart disease, reduce the incidence of angina and improve exercise tolerance. In acute myocardial infarction, if the early small doses of magnesium treatment for a long time, the patient can get some benefits.
