Prior studies provided inconsistent results regarding long-term effect of β-blocker use on clinical outcomes in postmyocardial infarction (MI) patients.
We searched for articles regarding long-term effect of β-blocker use on clinical outcomes in patients after MI and published them before July 2021 in the databases as follows: PubMed, Web of Science, MEDLINE, EMBASE, and Google Scholar. STATA 12.0 software was used to compute hazard ratios (HRs) and their 95% confidence intervals (CIs).
The study indicated that β-blocker group had significantly lower long-term all-cause mortality, cardiovascular mortality, major adverse cardiac events (MACEs) in post-MI patients, compared to no β-blocker group (all-cause mortality: HR, 0.67; 95% CI: 0.56-0.80; cardiovascular mortality: HR, 0.62; 95% CI: 0.49-0.78; MACE: HR, 0.87; 95% CI: 0.75-1.00). The study indicated no significant long-term effect of β-blocker use on risk of hospitalization for heart failure (HF), risk of recurrent MI, risk of stroke, and risk of repeat revascularization in post-MI patients (risk of hospitalization for HF: HR, 0.82; 95% CI: 0.58-1.16; risk of recurrent MI: HR, 0.93; 95% CI: 0.78-1.11; risk of stroke: HR, 0.94; 95% CI: 0.79-1.12; risk of repeat revascularization: HR, 0.91; 95% CI: 0.80-1.04).
The meta-analysis demonstrated significant long-term effects of β-blocker use on all-cause mortality, cardiovascular mortality, and risk of MACE in post-MI patients, whereas no significant long-term effect was shown on risk of hospitalization for HF, risk of recurrent MI, risk of stroke, and risk of repeat revascularization in post-MI patients.
先前的研究对于β受体阻滞剂使用对心肌梗死（MI）后患者临床结局的长期影响给出了不一致的结果。
我们检索了关于β受体阻滞剂使用对MI后患者临床结局的长期影响且于2021年7月之前在以下数据库发表的文章：PubMed、科学网、医学期刊数据库、荷兰医学文摘数据库以及谷歌学术。使用STATA 12.0软件计算风险比（HRs）及其95%置信区间（CIs）。
该研究表明，与未使用β受体阻滞剂组相比，β受体阻滞剂组MI后患者的长期全因死亡率、心血管死亡率、主要不良心脏事件（MACEs）显著更低（全因死亡率：HR，0.67；95%CI：0.56 - 0.80；心血管死亡率：HR，0.62；95%CI：0.49 - 0.78；MACE：HR，0.87；95%CI：0.75 - 1.00）。该研究表明，β受体阻滞剂使用对MI后患者心力衰竭（HF）住院风险、复发性MI风险、中风风险以及再次血运重建风险没有显著的长期影响（HF住院风险：HR，0.82；95%CI：0.58 - 1.16；复发性MI风险：HR，0.93；95%CI：0.78 - 1.11；中风风险：HR，0.94；95%CI：0.79 - 1.12；再次血运重建风险：HR，0.91；95%CI：0.80 - 1.04）。
荟萃分析表明，β受体阻滞剂使用对MI后患者的全因死亡率、心血管死亡率以及MACE风险有显著的长期影响，而对MI后患者的HF住院风险、复发性MI风险、中风风险以及再次血运重建风险没有显著的长期影响。
