摘  要:目的探讨老年急性心肌梗死(AMI)存活患者血中早期炎症指标之一C反应蛋白(CRP)与其远期心力衰竭(HF)及死亡风险间的相关性。方法对收治的268例老年AMI存活患者行前瞻性研究。血浆hs-CRP水平与后期HF及死亡风险的相关性采用Kaplan-Meier法及Cox比例风险回归模型进行单变量和多变量回归分析。结果随访期间病死率为21%(56/268),后期HF发生率为23.9%(64/268)。多因素COX比例危险率模型分析提示:与血浆CRP水平四分位最低均值(CRP≤11.23 mg/L)相比,次低CRP水平组(11.24~22.07 mg/L)、高CRP水平组(22.08~37.07 mg/L)和最高CRP水平组(≥37.08 mg/L)的后期并发HF及死亡风险均进行性增加。其后期HF及死亡风险的危险比(HR)各自分别为1.021(CI:0.557~4.776)、1.537(CI:0.788~3.432)、3.091(CI:1.442~8.233)、6.772(CI:3.12~11.323)及1.120(CI:0.998~2.897)、1.447(CI:0.997~3.125)、3.542(CI:2.116~6.099)、4.233(CI:1.879~7.87)。结论血浆hs-CRP水平是老年AMI存活患者远期发生HF及死亡风险的独立预测因子。Objective To study the relationship between C-reactive-protein(CRP) and long-term risk of death and heart failure(HF) in elderly survivors of acute myocardial infarction(MI).Methods We studied prospectively 268 elderly patients admitted with acute MI and discharged from hospital in stable condition.The relationship between C-reactive-protein(CRP) and long-term risk of death and heart failure(HF) was analyzed by Kaplan-Meier and Cox proportional hazard model.Results During a median follow-up of 20.7 months(range,3 to 24 months),56 patients died and 64 developed HF.In a multivariable Cox regression model,compared with patients in the first CRP quartile(CRP≤11.23 mg/L),the hazard ratios(HRs) for HF and death progressively increased with higher quartiles of CRP: 1.021(CI: 0.557 ~4.776) 、1.537(CI: 0.788 ~ 3.432) 、3.091(CI: 1.442 ~ 8.233) 、6.772(CI: 3.12 ~ 11.323) and 1.120(CI: 0.998 ~ 2.897) 、1.447(CI: 0.997 ~ 3.125) 、3.542(CI: 2.116 ~ 6.099) 、4.233(CI: 1.879 ~ 7.87).Conclusion C-reactive-protein is independent predictors of long term development of HF and mortality in elderly survivors of acute myocardial infarction.
