Results of Stent Supported Percutaneous Transluminal Coronary Angioplasty in Octogenarians With Coronary Artery Disease.

Abstract

Between January 1995 and July 1998, percutaneous transluminal coronary angioplasty was performed on 27 lesions in 24 octogenarians. Half of the patients were African American. Women comprised 67% of the study group. Patients with unstable angina and myocardial infarction constituted 54% of the cohort. Two-thirds of the patients (83%) had single vessel disease with predominant class A and B lesion complexity of the angioplasty site. Acute success rate was 92%. Stents were successfully placed in 11 subjects (46%). None had acute myocardial infarction, emergency coronary artery bypass surgery, or stroke as a complication of the procedure. One patient presenting with acute myocardial infarction complicated by cardiogenic shock, died. Significant bleeding complications requiring blood transfusions occurred in 17% of patients. Of the patients, 23 (96%) were discharged in a clinically stable condition. Follow up during a two year period was completed in 21 patients (88%). One patient died of cancer. Four subjects (19%) underwent repeat percutaneous transluminal coronary angioplasty. One other patient had recurrent chest pain requiring multiple hospitalizations. The remaining 16 patients (76%) remained free of recurrence of angina. We concluded that percutaneous transluminal coronary angioplasty with stent placement can be performed in octogenarians with a high rate of clinical and angiographic success with an acceptable range of morbidity and mortality, and favorable long term (two year) outcome.
