 note = {Clinical efficacy of percutaneous transluminal coronary angioplasty (PTCA) in elderly patients and evaluation of its safety has not been established. We attempted to perform PTCA in 67 patients aged 70 years or older (mean age 75 years) out of 302 patients between September 1983 and March 1988. A successful dilatation was achieved in 46/79 cases (58.2%) of elderly patients in comparison with 235/338 cases (69.5%) in patients younger than 70 years. There was no significant difference of the success rate. Mortalities were 3.0% in elderlies and 3.4% in youngers, but these rates decreased 0% and 0.9% of elective PTCA to angina pectoris. PTCA requires shorter hospitalization time and allows more rapid return to social activities. These data suggest that PTCA can be performed relatively safe and efficacious in selected geriatric patients.},
