[The Registry for Angioplasty in Infarction (RAI): brief preliminary report on the main indicators and process of acute outcome].
1997
BACKGROUND: Emergency coronary angioplasty can be the treatment of choice in selected patients with acute myocardial infarction in centers with adequate facilities and organization. METHODS: A multicenter observational study in patients with high-risk acute myocardial infarction was conducted to evaluate the quality of emergency angioplasty treatment according to process, acute and long-term outcome, and use of resources. RESULTS: The RAI registry included 345 patients with high-risk acute myocardial infarction who were admitted to six participating centers over a thirteen-month period. Emergency coronary angiography was performed in 261 patients (76%) and was followed by immediate angioplasty in 236 of them (68%). Mean door-to-procedure time was 58 +/- 47 min. Severe left ventricular failure was present at admission in 35 (13%) of the 261 patients with emergency coronary angiography; and 29 of them were in cardiogenic shock (11%). Overall, in-hospital mortality for patients with angioplasty was 7.6%; i.e., 43% and 3.7% for patients with and without shock, respectively. CONCLUSIONS: Despite logistical limitation, in centers with emergency angioplasty programs this treatment can be performed with favorable process and acute outcome characteristics in patients with high-risk myocardial infarction.
