摘      要:Background The role of early revascularization among patients with acute myocardial infarction complicated by cardiogenic shock remains controversial. Angioplasty registries, while suggesting a benefit, are subject to selection bias, and clinical trials have been underpowered to detect early benefits. If an invasive strategy is beneficial in this population, patients admitted to hospitals with onsite coronary revascularization might be expected to have a better prognosis. We sought to determine whether access to cardiovascular resources at the admitting hospital influenced the prognosis of patients with acute myocardial infarction complicated by cardiogenic shock. Methods By use of the Cooperative Cardiovascular Project database (a retrospective medical record review of Medicare patients discharged with acute myocardial infarction), we identified patients aged greater than or equal to65 years whose myocardial infarction was complicated by cardiogenic shock. Results Of the 601 patients with cardiogenic shock, 287 (47.8%) were admitted to hospitals without revascularization services and 3 14 (52.2%) were admitted to hospitals with coronary angioplasty and coronary artery bypass surgery facilities. Clinical characteristics were similar across the subgroups. Patients admitted to hospitals with revascularization services were more likely to undergo coronary revascularization during the index hospitalization and during the first month after acute myocardial infarction. After adjustment for demographic, clinical, hospital, and treatment strategies, the presence of onsite revascularization services was not associated with a significantly lower 30-day (odds ratio 0.83, 95% CI 0.47, 1.45) or 1-year mortality (odds ratio 0.91, 95% CI 0.49, 1.72). Conclusions In a community-based cohort, patients with acute myocardial infarction complicated by cardiogenic shock did not have significantly different adjusted 30-day and 1-year mortality, irrespective of the revascularization capab
