• Objective: 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. • Patients and Methods: 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). • Results: 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. • Conclusion: This study shows that PCI for acute myocardial infarction can be performed safely and effectively in a community hospital without on-site cardiac surgery.
