Emergency coronary angioplasty for acute myocardial infarction. Results from a community hospital.

Emergency coronary angioplasty was performed in 127 patients presenting to a community hospital with acute myocardial infarction. Reperfusion and successful dilatation were performed in 117 patients (92%) at 3.3 +/- 1.8 hours from the onset of pain. Eleven patients (8.6%) died, ten patients (7.9%) developed reocclusion, and ten patients (7.9%) required coronary bypass surgery during the initial hospitalization. Late restenosis occurred in 36% (27/76) of patients restudied or 27% (27/100) of patients at risk for restenosis. Ejection fraction improved in patients with patent vs occluded vessels (8.4% +/- 8.2% vs -4.1% +/- 6.0%) and improved most in anterior vs inferior vs posterolateral infarcts (11.0% +/- 8.4% vs 6.8% +/- 6.4% vs 2.6% +/- 7.5%). Posthospitalization follow-up in all patients (mean, 13.4 months) revealed only one late death. Of the patients followed up, 83% had no angina, and 17% of patients had mild angina. Our experience demonstrates that coronary angioplasty for acute myocardial infarction can be performed in the community hospital by an experienced cardiovascular laboratory team with a high success rate, a low reocclusion rate, an improvement in ejection fraction, and an excellent long-term prognosis. The community hospital setting allows early access to patients and creates the potential for early reperfusion and myocardial salvage.
