Acute myocardial infarction triggered by physical exertion: a systematic review and meta-analysis
Pooled result · Exertion-related acute MIResult — go to the resultRelative risk 3.46 95% CI 3.16–3.78Authors' conclusion
Every tenth AMI may be assigned to physical exertion. The impact was more pronounced among younger patients, those exposed to exertion one to three times a week, and those not taking β-blockers.

Modifiers of exertion-related acute MI (meta-regression)
- Per additional year of age: RR increased
- ∼3%
