AIMS: Percutaneous coronary intervention (PCI) improves outcomes in non-ST elevation acute coronary syndromes (NSTE-ACSs). Octogenarians, however, were underrepresented in the pivotal trials. This study aimed to assess the effect of PCI in patients ≥80 years old. METHODS AND RESULTS: We used data from the SWEDEHEART registry for all hospital admissions at eight cardiac care centres within Västra Götaland County. Consecutive patients ≥80 years old admitted for NSTE-ACS between January 2000 and December 2011 were included. We performed instrumental variable analysis with propensity score. The primary endpoint was all-cause mortality at 30 days and one year after index hospitalization. During the study period 5200 patients fulfilled the inclusion criteria. In total, 586 (11.2%) patients underwent PCI, the remaining 4613 patients were treated conservatively. Total mortality at 30 days was 19.4% (1007 events) and 39.4% (1876 events) at one year. Thirty-day mortality was 20.7% in conservatively treated patients and 8.5% in the PCI group (adjusted odds ratio 0.34; 95% confidence interval 0.12-0.97, p = 0.044). One-year mortality was 42.1% in the conservatively treated group and 16.3% in the PCI group (adjusted odds ratio 0.97; 95% confidence interval 0.36-2.51, p = 0.847). CONCLUSIONS: PCI in octogenarians with NSTE-ACS was associated with a lower risk of mortality at 30 days. However, this survival benefit was not sustained during the entire study-period of one-year.
