View article: Coronary artery disease and the risk of life-threatening cardiac events after age 40 in long QT syndrome
Coronary artery disease and the risk of life-threatening cardiac events after age 40 in long QT syndrome Open
Background and aims Long QT syndrome (LQTS) and coronary artery disease (CAD) are both associated with increased risk of ventricular tachyarrhythmia . However, there are limited data on the incremental risk conferred by CAD in adult patien…

Association Between Intensive Care Unit Usage and Long‐Term Medication Adherence, Mortality, and Readmission Among Initially Stable Patients With Non–ST‐Segment–Elevation Myocardial Infarction Open
Background Hospitals in the United States vary in their use of intensive care units ( ICU s) for hemodynamically stable patients with non– ST ‐segment–elevation myocardial infarction ( NSTEMI ). The association between ICU use and long‐ter…

Readmissions After Acute Myocardial Infarction: How Often Do Patients Return to the Discharging Hospital? Open
Background When patients require readmission after a recent myocardial infarction ( MI ), returning to the discharging (index) hospital may be associated with better outcomes as a result of greater continuity in care. However, little evide…

Association of acute myocardial infarction cardiac arrest patient volume and in‐hospital mortality in the United States: Insights from the National Cardiovascular Data Registry Acute Coronary Treatment And Intervention Outcomes Network Registry Open
Background Little is known about how differences in out of hospital cardiac arrest patient volume affect in‐hospital myocardial infarction (MI) mortality. Hypothesis Hospitals accepting cardiac arrest transfers will have increased hospital…
View article: Advanced Practice Provider Versus Physician‐Only Outpatient Follow‐Up After Acute Myocardial Infarction
Advanced Practice Provider Versus Physician‐Only Outpatient Follow‐Up After Acute Myocardial Infarction Open
Background Physician shortages and reimbursement changes have led to greater use of advanced practice providers ( APP s). Prevalence of and outcomes associated with APP care following myocardial infarction are unknown. Methods and Results …
