Comparative efficacy of low-density lipoprotein cholesterol (LDL-C)-lowering therapies in first-time vs. recurrent myocardial infarction prevention: a meta-analysis of large-scale randomized controlled trials
- Systematic review and meta-analysis of randomised trials
- random-effects model
- Randomized controlled trials (RCTs) with ≥1000 patient-years of follow-up
Authors' conclusion
Our findings suggest that LDL-C-lowering therapies may offer a greater benefit in preventing first-time MI compared with recurrent MI.
Study context
- Population
- Participants in large-scale RCTs of LDL-C-lowering therapies for prevention of first-time or recurrent myocardial infarction (MI)
- Participants
- 180,304 participants · 22 RCTs
- Comparison
- LDL-C-lowering therapies in first-time vs recurrent MI prevention
- First-time MI preventionn = 79,604
- Recurrent MI preventionn = 100,700
- Outcome
- MI risk (RR), first-time vs recurrent MI prevention
