Abstract

Background: Recent improvement in the care of patients with myocardial infarction should lead to better outcome. The goal of this study was to evaluate the incidence of all cause cardiogenic shock (CS) and CS occurring in the setting of ST elevation myocardial infarction (STEMI) in the United States. Method: The Nationwide Inpatient Sample (NIS) database was utilized to calculate the age-adjusted incident rate of CS from 1996 to 2006 based on ICD-9 coding in the setting of STEMI. Furthermore, we evaluated this trend based on race and gender. Results: A total population of 52,784,917 patients was available between 1996 and 2006. We found that the incidence of all cause CS has not changed over time. However, in the setting of STEMI, CS has been declining slowly over the last 10. years. The age-adjusted rate for CS was 4.3 per 100,000 in 1996 which remained steady with an incidence of 3.1 per 100.000 in 2006 (p < 0.01). This decline was persistent across different race or gender. However, African Americans and female gender had persistently lower rate of CS. Conclusion: Advancement in the treatment of acute STEMI has led to gradual reduction in the incidence of STEMI related cardiogenic shock irrespective of ethnicities or gender suggesting improving outcome of patients presenting with STEMI in recent years.
