冠心病为常见病、多发病,其病因学尚无定论,但其发病和脂质代谢障碍密切相关。在高脂蛋白血症的患者中,冠心病发病率显著增高,低密度脂蛋白—胆固醇(HDL—ch)和极低密度脂蛋白—胆固醇—(VHDL—ch)升高的人容易发生动脉粥样硬化,在临床上已受到重视。近年来大量研究表明,血浆高密度脂蛋白—胆固醇(HDL—ch)含量与冠心病发生率呈负相关,血浆HDL—ch有使动脉粥样硬化病变消退的作用。为了探索一个能为早期预测冠心病,为防治工作提供一个有用的数据,我们利用干部体检的机会,试图通过人群调查,分析血浆中高密度脂蛋白—胆固醇与冠心病的联系。对象及方法 Coronary heart disease as a common disease, frequently-occurring disease, the etiology is inconclusive, but its incidence and lipid metabolism disorders are closely related. In patients with hyperlipoproteinemia, the incidence of coronary heart disease is significantly increased. People with elevated levels of low-density lipoprotein-cholesterol (HDL-ch) and very-low-density lipoprotein cholesterol (VHDL-ch) Like sclerosis, has been clinically valued. In recent years, a large number of studies have shown that the plasma level of HDL-cholesterol is negatively correlated with the incidence of coronary heart disease. Plasma HDL-ch has the role of regression of atherosclerotic lesions. In order to explore a data that can provide a useful tool for early prediction of coronary heart disease and prevention and treatment, we used the opportunity of medical examination and attempted to analyze the relationship between plasma high-density lipoprotein-cholesterol and coronary heart disease through population survey.
