Background The role of race and ethnicity in the outcomes of cardiac arrest (CA) complicating acute myocardial infarction (AMI) is incompletely understood. Methods and Results This was a retrospective cohort study of adult admissions with AMI-CA from the National Inpatient Sample (2012-2017). Self-reported race/ethnicity was classified as White, Black, and others (Hispanic, Asian or Pacific Islander, Native American, Other). Outcomes of interest included in-hospital mortality, coronary angiograp...

AIMS Excimer Laser Coronary Angioplasty with adjunctive contrast (ELCA-con) is described as one potential option to facilitate intra-coronary stent expansion; however, the benefits and risks of this technology remain incompletely understood. We performed a retrospective single center study to evaluate procedural success, risks, and clinical outcomes of ELCA-con assisted percutaneous coronary intervention (PCI) for stent under-expansion. METHODS AND RESULTS Twenty-six consecutive patients underwe...

Background There are limited contemporary data on the use of emergent coronary artery bypass grafting (CABG) in acute myocardial infarction (AMI). Methods and Results Adult (>18 years) AMI admissions were identified using the National Inpatient Sample (2000-2017) and classified by tertiles of admission year. Outcomes of interest included temporal trends of CABG use, age-, sex-, and race-stratified trends in CABG use, in-hospital mortality, hospitalization costs, and hospital length of stay. Of t...

OBJECTIVES The aim of this study was to examine the effect of CYP2C19 genotype on clinical outcomes in patients with coronary artery disease (CAD) who predominantly underwent percutaneous coronary intervention (PCI), comparing those treated with ticagrelor or prasugrel versus clopidogrel. BACKGROUND The effect of CYP2C19 genotype on treatment outcomes with ticagrelor or prasugrel compared with clopidogrel is unclear. METHODS Databases through February 19, 2020, were searched for studies reportin...

AIMS There are limited contemporary data on the use of initial fibrinolysis in ST-segment elevation myocardial infarction cardiogenic shock (STEMI-CS). This study sought to compare the outcomes of STEMI-CS receiving initial fibrinolysis vs. primary percutaneous coronary intervention (PPCI). METHODS Using the National (Nationwide) Inpatient Sample from 2009 to 2017, a comparative effectiveness study of adult (>18 years) STEMI-CS admissions receiving pre-hospital/in-hospital fibrinolysis were comp...

AIMS: There are limited data on the trends and outcomes of mechanical circulatory support (MCS)-assisted early percutaneous coronary intervention (PCI) in acute myocardial infarction with cardiogenic shock (AMI-CS). METHODS AND RESULTS: Using the National Inpatient Sample database from 2005-2014 a retrospective cohort of AMI-CS admissions receiving early PCI (hospital day zero) was identified. MCS use was defined as intra-aortic balloon pump (IABP), percutaneous left ventricular assist device (p...

There are few studies documenting the changing epidemiology and outcomes of shock in cardiac intensive care unit (CICU) patients. We sought to describe the changes in shock epidemiology and outcomes over time in a CICU population. METHODS We included 1859 unique patients admitted to the Mayo Clinic Rochester CICU from 2007 through 2018 with an admission diagnosis of shock. Temporal trends, including mortality, were assessed across 3-year periods. RESULTS Shock comprised 15.1% of CICU admissions ...
