    Abstract:
    BACKGROUND: Percutaneous coronary intervention (PCI) in octogenarian patients has been associated with increased cardiovascular morbidity and mortality. This study aimed to assess acute and intermediate-term clinical outcomes among octogenarians undergoing PCI. METHODS: The authors identified 97 consecutive patients aged > or =80 years who underwent PCI using stents between November 2000 and February 2002 at their institution. The patients were divided into three groups according to clinical presentation: (1) acute myocardial infarction (AMI, n = 31); (2) unstable angina pectoris (UAP, n = 28); and (3) stable angina pectoris (SAP, n = 38). Procedural data, and in-hospital and six-month clinical outcomes were obtained and adjudicated for all patients. RESULTS: Overall mean age was 84 +/- 3 years, 67% of patients were males and 73% had multivessel coronary disease. In-hospital outcomes varied according to clinical presentation: procedural success was 78% in AMI patients (including shock patients), 93% in UAP, and 95% in SAP patients. Likewise, hospital mortality was 26% in AMI, 3.6% in UAP, and 0% in SAP patients (p = 0.0003). Among AMI patients, hospital mortality was extremely high in patients with cardiogenic shock (67% versus 4.6% in AMI without shock, p < 0.0001). Cumulative event rate at six months also varied according to clinical presentation: mortality/MI and target vessel revascularization (TVR) rates were 29%, 3.6%, and 0% in AMI, 7.1%, 7.4%, and 11% in UAP and 0%, 5.3%, and 7.9% in SAP patients. Multivariate analysis identified cardiogenic shock as the most powerful risk factor for predicting mortality (odds ratio = 42, p = 0.03). CONCLUSIONS: These results show that clinically stable octogenarian patients undergoing PCI have favorable procedural and intermediate-term prognosis. In contrast, cardiogenic shock has a profound negative prognostic impact on octogenarians despite 'aggressive' PCI attempts.
