title: Midterm outcomes and quality of life following percutaneous coronary intervention in nonagenarians.
abstract: The midterm clinical and functional benefits of percutaneous coronary intervention in patients aged ≥90 years have not been clearly defined. From January 2005 to June 2009, 173 patients aged ≥90 years underwent diagnostic cardiac catheterization, of whom 90 underwent percutaneous coronary intervention. There were 45 men (50%) and 45 women (50%), with a mean age of 92 years (range 90 to 101). Of these, 24 patients (27%) presented with ST-segment elevation myocardial infarction, 31 (34%) with non-ST-segment elevation myocardial infarction, 28 (31%) with unstable angina pectoris, and 2 (2%) with stable angina pectoris; 5 patients (6%) were studied for preoperative risk assessment. A total of 127 lesions were successfully treated using 102 drug-eluting stents and 37 bare-metal stents, with a mean of 1.5 stents per patient. Postprocedural complications included renal insufficiency in 5 patients (5.6%), heart failure in 6 patients (6.7%), and cardiogenic shock in 2 patients (2.2%). Seventy-seven patients (85.6%) experienced no postprocedural complications. In-hospital mortality was 7.8%, and actuarial survival was 61.5 ± 5.2% at 24 months and 31.6 ± 6.1% at 48 months. The SF-36 Health Survey was administered at follow-up, and results demonstrated a quality of life similar to that of the general population corrected for age and gender. In conclusion, this study demonstrates that percutaneous coronary intervention in nonagenarians can be accomplished with low mortality and morbidity and excellent midterm results. Moreover, functional improvement in nonagenarians supports enhanced quality of life comparable to that of the general population.
