Hypercholesterolemia, particularly high levels of LDL-cholesterol, is a well established risk factor for coronary heart disease. Lipid-lowering therapies are associated with a reduction in cardiovascular morbidity and mortality in secondary as well as primary prevention. These trials are consistent with epidemiological studies and emphasize the importance of the benefit in terms of the number of cardiovascular events avoided per 1000 patients treated. However, extrapolation of the data to general practice must be cautions, as most of the trials were conducted in populations displaying a high absolute risk level, including few women, and excluding persons older than 75 years. However, subgroup analysis showed that the beneficial effect is independent of age and pretreatment lipid levels in the range studied. The precise lipid pattern should be considered before any treatment is started. Diet is the first step approach and should be continued even after introduction of lipid-lowering drug therapy. Statins are treatments of choice in case of hypercholesterolemia type IIa. The target level of LDL-cholesterol is less than 1.30 g/l in patients with known coronary heart disease. Fibrates may be useful in patients with hypertriglyceridemia, and/or low HDL-cholesterol level or in the case of intolerance to statins.
高胆固醇血症,尤其是高水平的低密度脂蛋白胆固醇,是公认的冠心病危险因素。降脂治疗与二级预防及一级预防中心血管发病率和死亡率的降低相关。这些试验与流行病学研究一致,并强调了每治疗1000例患者所避免的心血管事件数量方面获益的重要性。然而,将数据外推至一般临床实践时必须谨慎,因为大多数试验是在具有高绝对风险水平的人群中进行的,包括很少的女性,且排除了75岁以上的人群。然而,亚组分析表明,在所研究的范围内,有益效果与年龄和治疗前血脂水平无关。在开始任何治疗之前,应考虑确切的血脂模式。饮食是第一步措施,即使在开始降脂药物治疗后也应继续。他汀类药物是IIa型高胆固醇血症的首选治疗药物。已知患有冠心病的患者,低密度脂蛋白胆固醇的目标水平应低于1.30g/l。贝特类药物可能对高甘油三酯血症和/或低高密度脂蛋白胆固醇水平的患者有用,或在对他汀类药物不耐受的情况下使用。
