There is conflicting evidence about the impact of social support on adverse outcome after acute myocardial infarction (MI). We examined the relation between single-living and long-term all-cause mortality after MI.
A prospective cohort study of 242 employed patients with MI followed up to 16 years after MI.
A total of 106 (43.8%) patients died during the follow-up. Single-living nearly doubled the risk of death; after adjusting for potential confounding factors, single-living was an independent predictor of death, with a hazard ratio of 2.55 (95% confidence interval: 1.52-4.30). Other predictors of death were diabetes mellitus, atrial fibrillation, age, and ejection fraction less than 35%.
Single-living is a prognostic determinant of long-term all-cause mortality after MI.
关于社会支持对急性心肌梗死(MI)后不良结局的影响,目前存在相互矛盾的证据。我们研究了独居与 MI 后长期全因死亡率之间的关系。
一项前瞻性队列研究,对 242 名有工作的 MI 患者进行随访,随访时间长达 16 年。
共有 106 名(43.8%)患者在随访期间死亡。独居使死亡风险几乎增加了一倍;在调整了潜在的混杂因素后,独居是死亡的独立预测因素,其危险比为 2.55(95%置信区间:1.52-4.30)。其他死亡预测因素包括糖尿病、心房颤动、年龄和射血分数<35%。
独居是 MI 后长期全因死亡率的预后决定因素。
