Incidence, timing, predictors and impact of acute heart failure complicating ST-segment elevation myocardial infarction in patients treated by primary percutaneous coronary intervention

摘要

Background: Acute heart failure (AHF) complicating ST-segment elevation myocardial infarction (STEMI) is recognized as an ominous complication. Previous studies mostly reported outcomes of heterogeneous, non-contemporary population. Moreover, few studies assessed the prognosis of AHF according to its timing. This study evaluated incidence, predictors and impact of AHF according to its timing in a homogeneous STEMI patients population treated by primary percutaneous coronary intervention (pPCI).
