Prognostic impact of sarcopenia following myocardial infarction: a systematic review and meta-analysis of mortality and recurrent myocardial infarction (MI)
Pooled result · All-cause mortalityResult — go to the resultOdds ratio 2.84 95% CI 1.85–4.36Authors' conclusion
Sarcopenia assessed around the time of MI is consistently associated with a threefold increase in all-cause mortality, with robust effects across short- and long-term follow-up.
Study context
- Population
- Patients after MI
- Participants

- Comparison
- Sarcopenia vs no sarcopenia after MI
- Outcome
- All-cause mortality
Methodological detailsCertainty of evidence moderate for mortality, very low for recurrent MI

Further pooled results
All-cause mortality, follow-up ≤12 months
- Mortality effect consistent at ≤12 months: OR
- 2.55 (95% CI 1.42-4.58)
All-cause mortality, follow-up >12 months
- Mortality effect consistent at >12 months: OR
- 3.21 (95% CI 1.72-6.02)
Recurrent MI (2 cohorts)
- Pooled OR for recurrent MI, possible increased risk but highly imprecise and heterogeneous (95% CI 0.22-22.06; I2 = 81%); certainty very low
- 2.21
- Precluding definitive conclusions
All-cause mortality, PCI all-comer cohorts (sensitivity analysis)
- Three PCI all-comer cohorts also indicated higher mortality
- Sensitivity only
