The study evaluates the effect of statin therapy on the prognostic impact of non-sustained ventricular tachycardia (NSVT) occurring after acute ST-elevation myocardial infarction (STEMI).
From the German Acute Coronary Syndrome Registry (ACOS), 3137 patients with STEMI and in-hospital Holter monitoring were analysed. Three hundred and forty-six (11.0%) patients had NSVT. When compared with patients with no documented NSVT, patients with NSVT were older, more often had myocardial infarction in their history, diabetes mellitus, and an ejection fraction <40%. Regarding frequency of drug application, medication at discharge did not (beta-blockers, ACE-inhibitors, amiodarone) or only slightly (acetylsalicylic acid, statins, and sotalol) differ between both groups. Multivariable analysis of 1 year mortality, adjusted for age, gender, diabetes, reperfusion therapy, ejection fraction <40%, and beta-blocker therapy showed the following results: In patients without statin treatment and no NSVT, 1 year mortality after STEMI was 9.2%, but increased to 25.0% [odds ratio (OR) 3.02; 95% confidence interval (CI) 1.47-6.20], if NSVT were present. In patients on statin treatment and no NSVT, 1 year mortality was only 3.2%, and in the presence of NSVT 1 year mortality was not significantly increased anymore (5.3%; OR 1.03; 95% CI 0.55-1.92).
After STEMI, only in patients not on statin treatment, the occurrence of NSVT is associated with a significant and marked increase in 1 year mortality.
本研究评估他汀类药物治疗对急性ST段抬高型心肌梗死(STEMI)后发生的非持续性室性心动过速(NSVT)预后影响的作用。
对德国急性冠状动脉综合征注册研究(ACOS)中3137例STEMI且进行院内动态心电图监测的患者进行分析。346例(11.0%)患者发生NSVT。与无NSVT记录的患者相比,发生NSVT的患者年龄更大,既往心肌梗死、糖尿病病史更常见,且射血分数<40%。关于药物应用频率,两组间出院时用药情况(β受体阻滞剂、血管紧张素转换酶抑制剂、胺碘酮)无差异或仅有轻微差异(阿司匹林、他汀类药物和索他洛尔)。对1年死亡率进行多变量分析,校正年龄、性别、糖尿病、再灌注治疗、射血分数<40%和β受体阻滞剂治疗后,结果如下:未接受他汀类药物治疗且无NSVT的患者,STEMI后1年死亡率为9.2%,但如果存在NSVT,死亡率则升至25.0%[比值比(OR)3.02;95%置信区间(CI)1.47 - 6.20]。接受他汀类药物治疗且无NSVT的患者,1年死亡率仅为3.2%,存在NSVT时1年死亡率不再显著升高(5.3%;OR 1.03;95% CI 0.55 - 1.92)。
STEMI后,仅在未接受他汀类药物治疗的患者中,NSVT的发生与1年死亡率显著且明显升高相关。
