冠心病患者血脂和脂蛋白水平及与心功能的关系

Relationship of lipids and lipoproteins with cardiac function in patients with coronary heart disease

目的探讨冠心病患者血脂和脂蛋白水平与左心功能的关系.方法分析584例冠心病患者的血清总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-ch)水平与左心功能的相关性.结果除高密度脂蛋白胆固醇(HDL-ch)外,冠心病患者左心功能不全的发生与年龄、收缩压(SBP)、舒张压(DBP)、血糖、体重指数(BMI)、吸烟和TC、LDL-ch高度相关( P<0.001);随着TC、LDL-ch水平升高,左心室射血分数(LVEF)及左心室高峰充盈率(LVPFR)降低( P<0.05～0.01);Logistic回归分析显示,TC、LDL-ch与冠心病患者左心功能不全的发生存在显著相关性( P＜0.001).结论冠心病患者血清TC、LDL-ch水平与左心功能不全呈正相关,防治冠心病合并高血脂时,应重视改善冠状动脉粥样硬化,降低TC、LDL-ch水平.

ObjectiveTo investigate the correlation of lipids and lipoproteins with cardiac function in patients with coronary heart disease (CHD).MethodsParameters of blood pressure, serum lipids and lipoproteins, clinical features, radionuclide ventriculographic and coronary angiographic findings were analyzed retrospectively in 584 CHD patients treated with standard treatment.ResultsThe left cardiac dysfunction of CHD patients was correlative positively with age, systolic blood pressure (SBP), diastolic blood pressure (DBP), blood glucose, body mass index (BMI), smoking, total cholesterol(TC) and low density lipoprotein cholesterol(LDL-ch) significantly( P<0.001), not correlative with high density lipoprotein-cholesterol (HDL-ch). The left ventricular ejection fraction (LVEF) and left ventricular peak filling rate (LVPFR) were decreased along with the levels of TC and LDL-ch increased ( P<0.05～0.01).ConclusionTC and LDL-ch are positively correlative with left cardiac dysfunction in CHD patients. In order to reduce cardiac damage of CHD associated with hyperlipoidemia, more attention should be paid to the amelioration of coronary arteriosclerosis and the reduction of serum lipids and lipoproteins.
