AbstractObjectives. Developments in medication and coronary interventions have improved coronary artery disease (CAD) treatment. We studied long-term outcomes in an observational, real-life population of CAD patients undergoing percutaneous coronary intervention (PCI) depending on the presentation and the stent type used. Design and results. Register included 789 consecutive patients undergoing PCI. Follow up period was three years with primary composite outcome (MACE) of all cause -mortality, myocardial infarction and target lesion revascularization. Mean age was 65 ± 11 and 69% were male. New-generation drug-eluting stents (DES-2) were associated with lower adjusted rates of MACE (HR 0.47; 95% CI 0.29-0.77) but not mortality (HR 0.50; 95% CI 0.22-1.14) in comparison to bare-metal stents. Patients with STEMI (14.4%) or NSTEMI (13.7%) had higher crude mortality rates than those with unstable (4.5%) or stable CAD (3.1%; p < .001). The association diminished after adjustments in NSTEMI (HR 2.01; 95% CI 0.88-4.58). Among smokers 45% quitted and 36% achieved recommended cholesterol levels. Conclusions. The overall prognosis was good. Irrespective of comorbidities, NSTEMI was not associated with worse outcome than stable CAD. DES-2 was associated with lower rates of MACE than BMS without affecting mortality rate. Patients succeeded better in smoking cessation than reaching recommended cholesterol levels.
