OBJECTIVES: The purpose of this study was to examine treatment and outcomes in patients admitted to the hospital with acute myocardial infarction (AMI) complicated by congestive heart failure (CHF). BACKGROUND: Although cardiogenic shock complicating AMI has been studied extensively, the hospital course of patients presenting with CHF is less well established. METHODS: The Second National Registry of Myocardial Infarction (NRMI-2) was analyzed to determine hospital outcomes for patients with ST-elevation AMI admitted with CHF (Killip classes II or III). RESULTS: Of 190,518 patients with AMI, 36,303 (19.1%) had CHF on admission. Patients presenting with CHF were older (72.6 +/- 12.5 vs. 63.2 +/- 13.5 years), more often female (46.8% vs. 32.1%), had longer time to hospital presentation (2.80 +/- 2.6 vs. 2.50 +/- 2.4 h), and had higher prevalence of anterior/septal AMI (38.8% vs. 33.3%), diabetes (33.1% vs. 19.5%), and hypertension (54.6% vs. 46.1%) (all p < 0.0005). Also, they had longer lengths of stay (8.1 +/- 7.1 vs. 6.8 +/- 5.3 days, p < 0.00005) and greater risk for in-hospital death (21.4% vs. 7.2%; p < 0.0005). Patients with CHF were less likely to receive aspirin (75.7% vs. 89.0%), heparin (74.6% vs. 91.1%), oral beta-blockers (27.0% vs. 41.7%), fibrinolytics (33.4% vs. 58.0%), or primary angioplasty (8.6% vs. 14.6%), and more likely to receive angiotensin-converting enzyme inhibitors (25.4% vs. 13.0%). Congestive heart failure on admission was one of the strongest predictors of in-hospital death (adjusted odds ratio 1.68; 95% confidence interval 1.62, 1.75). CONCLUSIONS: Patients with AMI presenting with CHF are at higher risk for adverse in-hospital outcomes. Despite this, they are less likely to be treated with reperfusion therapy and medications with proven mortality benefit.
