To compare the safety and efficacy of percutaneous coronary intervention (PCI) for acute myocardial infarction performed at a hospital without cardiac surgical capability with PCI performed for acute myocardial infarction at a center with on-site surgery.


We included patients with acute myocardial infarction in whom PCI was performed from March 1, 2000, through May 31, 2002, at a community hospital (Immanuel St Joseph's) without on-site surgery. The procedural success, in-hospital adverse cardiac events, and 6-month follow-up were compared with those of PCI performed for acute myocardial infarction in matched controls from January 1, 2000, through February 28, 2002, at a center with cardiac surgery (Saint Marys Hospital).


One hundred sixty patients (and 160 matched controls) underwent PCI for acute myocardial infarction. The procedural success rate was high and similar for the 2 groups (96% vs 95%; P=.79). In-hospital mortality, Q-wave myocardial infarction, and target vessel revascularization were low and similar for the 2 groups. No patient was referred for emergency coronary artery bypass graft surgery for failed PCI. Six-month survival from all-cause mortality was 96% for the Immanuel St Joseph's group and 94% for the Saint Marys Hospital group (P=.92). Subgroup analysis of patients with primary PCI for ST-segment elevation acute myocardial infarction revealed high procedural success and low and similar rates of major cardiac adverse events in the 2 groups.


This study shows that PCI for acute myocardial infarction can be performed safely and effectively in a community hospital without on-site cardiac surgery.
