The aim of this study was to assess the feasibility, safety and efficacy of primary angioplasty in acute myocardial infarction in a cardiology centre of a small urban community without on-site cardiac surgery. During 1995, 50 patients underwent angioplasty for MI in the first 12 hours. The average age was 66.7 +/- 12.6 years. Eighty six per cent of patients had at least one poor prognostic criteria (32% over 75 years of age, 70% anterior wall infarcts, 30% with heart rates > 100 min on admission). The angiographic result was successful in 45 patients (90%). The time between onset of pain and reopening the vessel was 240 +/- 116 min and between admission to the catheter laboratory and reopening 31 +/- 8 min. A coronary stent was implanted in 24 cases (48%) and intra-aortic balloon pumping was necessary in 14 cases (28%). Ischaemia recurred during the hospital phase in 7 cases (14%), 4 of which (8%) were caused by rethrombosis of the dilated artery: in 3 cases, the ischaemia was in another zone. No emergency coronary bypass surgery was required. The hospital mortality was 10%, always in patients over 80 years of age. The average duration of the hospital stay was 5.8 +/- 2.6 days with 15.7 +/- 7.3 days of convalescence. The average global cost was 61850 +/- 20686 F. These results were comparable to previously reported figures and confirm that primary angioplasty in acute infarction is possible and effective with an acceptable risk in a small urban community without on-site cardiac surgery.
