Abstract

Background: Electrophysiological (EP) complications are common following acute myocardial infarction (AMI) with direct impact on clinical outcomes and healthcare cost utilization.
Objective: We aimed to determine the temporal trends of EP complications and associated in-hospital mortality in patients with AMI for the years 2002-2013.
Methods: We queried nationwide inpatient sample from Healthcare Cost and Utilization Project of Agency for Healthcare Research and Quality for the years 2002-2013 using ICD-9 code. Multivariate hierarchical logistic regression models were used to determine predictors of in-hospital mortality. The primary outcome rates of EP complications and mortality in AMI patients.
Results: A total of 431,648 patients were admitted with AMI who experienced EP complications. Tachyarrhythmias were more common than bradyarrhythmias, with atrial fibrillation (16.25%) being the most common followed by ventricular tachycardia (6.03%). Third degree heart block was the most common bradyarrhythmias (1.24%). Left bundle branch block was the most conduction abnormality followed by right bundle branch block. A steady decline in in-hospital mortality was observed in AMI patients. Predictors of mortality were age>50, female gender, cardiac arrest, atrial fibrillation, complete heart block, ST-segment myocardial infarction and need for temporary pacemaker placement.
Conclusion: Although electrophysiological complications following AMI remains unchanged, a steady decline in in-hospital mortality was observed in AMI patients for the years 2002-2013.
