- The outcome after percutaneous coronary intervention (PCI) of all patients treated for stable and unstable angina pectoris from July 1992 to June 1993 (group A [n = 590], of whom 3.7% received stents) was compared with the outcome in patients treated from July 1996 to June 1997 (group B [n = 768], of whom 64.7% received stents). All patients were followed up for at least 1 year. PCI was performed due to unstable angina in 34.1% and 33.5% of patients in groups A and B, respectively. More patients in group B than in group A had systemic hypertension, previous coronary artery bypass grafting, and PCI. Within 1 year, 42.2% of patients in group A versus 27.2% in group B (p <0.001) either died, had a nonfatal acute myocardial infarction (AMI), or underwent a new revascularization procedure. The difference between the groups persisted after correction for differences in baseline characteristics. No difference was seen in the subgroup that had previously undergone PCI. Mortality (2.0% vs 1.4%, p = NS) and the composite of death plus AMI (6.6% vs 6.1%, p = NS) was similar in groups A and B. The diagnoses of unstable angina and systemic hypertension at the time of the procedure were also predictors of adverse outcome. Thus, in a cohort of patients treated after the general acceptance of stenting, the composite of death, AMI, and/or revascularization procedures was significantly less than that in the cohort treated before this increase in stenting. However, this did not result in a reduced frequency of death or AMI.
