Abstract

Heart failure (HF) complicating acute myocardial infarction (AMI) is common and is associated with poor clinical outcome. Limited data exist regarding the incidence and in-hospital mortality of AMI with HF (AMI-HF). We retrospectively analyzed 1,427 consecutive patients with AMI in the five major university hospitals in Korea at two time points, 1998 (n=608) and 2008 (n=819). Two hundred twenty eight patients (37.5%) in 1998 and 324 patients (39.5%) in 2008 of AMI patients complicated with HF (P=0.429). AMI-HF patients in 2008 were older, had more hypertension, previous AMI, and lower systolic blood pressure than those in 1998. Regarding treatments, AMI-HF patients in 2008 received more revascularization procedures, more evidence based medical treatment and adjuvant therapy, such as mechanical ventilators, intra-aortic balloon pulsation compared to those in 1998. However, overall in-hospital mortality rates (6.4% vs 11.1%, P=0.071) of AMI-HF patients were unchanged and still high even after propensity score matching analysis, irrespective of types of AMI and revascularization methods. In conclusion, more evidence-based medical and advanced procedural managements were applied for patients with AMI-HF in 2008 than in 1998. However the incidence and in-hospital mortality of AMI-HF patients were not significantly changed between the two time points.
