title: Coronary angioplasty in octogenarians: immediate and long-term results and comparison with a younger population.
abstract: The safety and efficacy of percutaneous transluminal coronary angioplasty (PTCA) was examined in a group of 91 octogenarians during 133 consecutive procedures and compared to the younger part of our PTCA population (3,443 procedures) during an 8-year study period.  Most octogenarians presented with refractory or unstable angina pectoris and multivessel involvement, but had normal left ventricular function.  The angiographic success rate was 84%. Technical failure was observed in 12% of cases and complications in 14%. Two early procedure related deaths were observed.  Restenosis was estimated at 24%.  The proportion surviving and the proportion without cardiac event estimated by the Kaplan-Meier method at 2 years were 0.89 and 0.60, respectively.  In comparison to the younger population, the immediate angiographic success was lower as a result of a higher incidence of technical failure (P less than 0.05).  Otherwise, no difference in terms of restenosis or overall related complication rate was noted (P greater than 0.1).  It is concluded that PTCA is an efficient and safe therapeutic option for octogenarians with severe or refractory angina pectoris.  Technical failure is more frequently observed than in younger patients and explains a lower immediate angiographic success. Nevertheless, at 2-years follow-up, a large majority of patients are alive and asymptomatic.
