Methods: We extracted and analyzed data on all patients hospitalized for myocardial infarction in Slovenia (n = 15,639), focusing on CR participation – either comprehensive outpatient (introduced in 2017) or short-term residential (available throughout the study period 2015–2021). Impact on nation-wide CR participation rates was assessed by interrupted time series analysis; impact on patient-level outcomes (all-cause mortality and cardiovascular hospitalizations) was assessed using Kaplan Meier estimators and ‘doubly robust’ Cox regression with propensity score-derived inverse probability of treatment weighting. Results: Of the 11,815 eligible patients (event-free after 180-day landmark), 3819 (32.3%) attended CR. Nation-wide CR participation rates increased both in level (9.7%, 95% CI 6.3–3.1) and in trend (0.41% per month, 95% CI 0.22–0.60) after outpatient CR was introduced in 2017. After propensity score-based adjustment, participation in either CR was associated with lower event rates (12.8%, 17.2%, and 21.0% at 3-year follow-up for outpatient, residential, and no CR, respectively; p < 0.001). Risk reductions were significant for composite outcomes (outpatient: HR 0.58, 95% CI 0.47–0.70; residential: HR 0.79, 95% CI 0.68–0.93) and all-cause mortality (outpatient: HR 0.56, 95% CI 0.38–0.83; residential: HR 0.59, 95% CI 0.45–0.77), whereas the risk reduction for cardiovascular hospitalizations was only significant for outpatient CR (HR 0.60, 95% CI 0.48–0.74). The incremental cost-effectiveness ratio per life-year gained was €6421 and €7381 for outpatient and residential CR, respectively. Conclusions: Participation in either CR improves outcomes after myocardial infarction, but comprehensive outpatient CR conveys superior risk reductions, primarily through reduced cardiovascular hospitalizations.20252025-12-05 14:04:20Neznano24560UDK: 616.1ISSN pri članku: 2211-8179DOI: 10.5334/gh.1470COBISS_ID: 248823811sl
