It is widely assumed that acute benefit of statin therapy is mediated especially by non-lipid effects. The immediate influence of statins on lipid levels in patients with acute coronary syndrome (ACS) is, however, not clear. A total of 64 consecutive patients with ACS were randomized at admission to fluvastatin 80 mg (Group 1, N = 32) or standard therapy without statin (Group 2, N = 32). The levels of total cholesterol (TC), low-density-lipoprotein cholesterol (LDL-C), high-density-lipoprotein cholesterol (HDL-C), and triglycerides (TG) were examined at admission and after 24 h. Baseline characteristics were comparable in both groups. In Group 1, fluvastatin significantly decreased the levels of TC by 14.5%, LDL-C by 17.2%, and HDL-C by 10.0% (P < 0.001); TG were not influenced. In Group 2 only marginal reductions in TC (by 4.1%, P = 0.03) and HDL-C (by 7.5%, P < 0.01) were detected; the levels of LDL-C and TG were not changed. As compared with Group 2, in Group 1 the final levels of TC (P = 0.02) and LDL-C (P = 0.01) were significantly lower. Fluvastatin therapy, when started at admission in patients with ACS, significantly reduces TC and LDL-C already after 24 h. We suggest that the lipid-lowering effect of statins in the therapy of ACS is probably as prompt as non-lipid effects.
人们普遍认为,他汀类药物治疗的急性获益尤其由非脂质效应介导。然而,他汀类药物对急性冠状动脉综合征(ACS)患者血脂水平的即时影响尚不清楚。共有64例连续的ACS患者在入院时被随机分为氟伐他汀80mg组(第1组,N = 32)或无他汀类药物的标准治疗组(第2组,N = 32)。在入院时和24小时后检测总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)和甘油三酯(TG)水平。两组的基线特征具有可比性。在第1组中,氟伐他汀显著降低TC水平14.5%,LDL-C水平17.2%,HDL-C水平10.0%(P < 0.001);TG未受影响。在第2组中,仅检测到TC(降低4.1%,P = 0.03)和HDL-C(降低7.5%,P < 0.01)有轻微降低;LDL-C和TG水平未改变。与第2组相比,第1组中TC(P = 0.02)和LDL-C(P = 0.01)的最终水平显著更低。在ACS患者入院时开始使用氟伐他汀治疗,24小时后即可显著降低TC和LDL-C。我们认为,他汀类药物在ACS治疗中的降脂作用可能与非脂质效应一样迅速。
