Abstract
BACKGROUND: For low-risk patients with ST-elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI) the recommended optimal discharge timing is inconsistent in guidelines. The European Society of Cardiology guidelines recommend early discharge within 48-72 h, while the American College of Cardiology guidelines do not recommend a specific discharge strategy. In this systematic review and meta-analysis we compared outcomes with early discharge (≤3 days) versus late discharge (>3 days). METHODS: Randomized controlled trials (RCTs) and observational studies were selected after searching MEDLINE and EMBASE database. Meta-analysis was stratified according to study design. Outcomes were reported as random effects risk ratios (RR) with 95% confidence intervals. RESULTS: Seven RCTs comprising 1780 patients and 4 observational studies comprising 39,288 patients were selected. The RCT-restricted analysis did not demonstrate significant differences in terms of all-cause mortality (RR, 0.97 [0.23-4.05]) and major adverse cardiac events (MACE) (RR, 0.84 [0.56-1.26]). Conversely, observational study restricted analysis showed that early vs late discharge strategy was associated with a reduction in all-cause mortality (RR, 0.40 [0.23-0.71]) and MACE (RR, 0.45 [0.26-0.78]). There were no significant differences in hospital readmissions between early vs late discharge in both RCT or observational study analyses. CONCLUSIONS: Early discharge strategy in appropriately selected low-risk patients with STEMI undergoing PCI is safe and it has the potential to improve cost of care.
