    Abstract

    Background Current guideline recommendations encourage culprit vessel only percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease. However, recent studies have shown a better clinical outcome in patients who receive multivessel PCI. Aim To measure and compare clinical outcomes between partial revascularization (PR) versus complete revascularization (CR) in patients with STEMI and multivessel disease who underwent a cardiac rehabilitation programme. Methods We retrospectively reviewed the medical records of 282 patients with STEMI and multivessel disease who received PR or CR and were subsequently enrolled in a cardiac rehabilitation programme between July 2006 and November 2013 at La Paz University Hospital. The incidences of cardiovascular events, new PCI, hospital admissions for cardiovascular reasons and mortality were compared between the PR and CR groups. Results Overall, 143 patients received PR and 139 received CR. Baseline characteristics were similar in both groups, except for mean age (59.3 vs. 56.7 years; P = 0.02), diabetes mellitus prevalence (34.3% vs. 20.1%; P = 0.01) and number of arteries with stenosis (2.6 vs. 2.3; P = 0.001). During the mean follow-up of 48.0 ± 25.9 months, a cardiovascular event occurred in 23 (16.1%) PR patients and 20 (14.4%) CR patients, with no statistically significant differences in the early (hazard ratio: 0.61, 95% confidence interval: 0.19–1.89) or late (hazard ratio: 1.40, 95% confidence interval: 0.62–3.14) follow-up periods. Cox regression, adjusted for age, sex, presence of diabetes mellitus and number of affected coronary vessels, showed no difference in new cardiovascular event risk. Conclusions There were no statistical differences in clinical outcomes between PR and CR among patients who received cardiac rehabilitation.
