Abstract P367: Temporal Trends in Cardiogenic Shock and Disparities in Use of PCI Among Patients With Cardiogenic Shock by Race/Ethnicity and Gender, Florida 2001-2007

Background: In current ACC/AHA guidelines, early revascularization for cardiogenic shock (CS) complicating acute myocardial infarction (AMI) is a class 1 recommendation in patients aged < 75 years. However, whether the current focus on prompt revascularization during AMI has modified the prevalence of CS is unknown. Therefore, we examined state-wide temporal trends in the prevalence of CS and the use of percutaneous coronary intervention (PCI) by patient age, gender, and race/ethnicity. Methods: Using comprehensive inpatient surveillance for Florida hospitals, we examined all AMI patients (ICD-9-CM 410) discharged between 2001-2007. Data on age, gender, race/ethnicity, AMI type (ST-elevation (STEMI), non-ST-elevation (NSTEMI), and site unspecified), cardiogenic shock (ICD-9-CM 785.50, 785.51) and use of PCI were abstracted for each patient. Temporal trends in the prevalence of CS complicating AMI were examined. Logistic regression analysis was used to examine sociodemographic predictors of the use of PCI ...
