Coronary angioplasty in patients over 70. An analysis of 115 dilatations
1992
PURPOSE: To verify the validity of transluminal coronary angioplasty (PTCA) in the population over 70 years old. METHODS: Retrospectively, were analysed 115 PTCA performed in 89 elderly patients (70 to 85 years old) from January 1988 to January 1991. Three groups were defined: A) single vessel-77 (86.5%) patients; B) double vessel-9 (10.1%) patients; C) three vessel-3 (3.4%) patients. RESULTS: Of the 89 treated patients, 81.8% in group A, 72.2% in group B and 75% in group C were successfully dilated. The learning curve had showed increase in success rate after the first 250 angioplasties (from 60.6% to 82.5%). Treatment of acute myocardial infarction by direct thrombolysis was made in 7 patients (6 S, 1 I). Major complications included: deaths (4.4%), ventricular fibrillation (1.08%), acute coronary occlusion (6.6%). Emergency coronary artery bypass grafting was required in 4.4% with one death. CONCLUSION: Coronary angioplasty is an effective treatment in elderly patients and may be performed with acceptable success and with low complications.
