Emergency department weekend presentation and mortality in patients with acute myocardial infarction.
The purpose of this research was to determine if weekend and holiday presentation is associated with increased mortality in EDs among patients with acute myocardial infarction (AMI) in New Jersey. It found that weekend/holiday presentation to the ED for AMI was associated with increased mortality. The effect may be related to the limited availability of resources on weekend/holidays compared to weekdays.

Baseline, time-updated, and cumulative HIV care metrics for predicting acute myocardial infarction and all-cause mortality.
The researchers studied prediction rates of myocardial infarction in those with HIV. They found that the Veterans Aging Cohort Study (VACS) Index provided better acute myocardial infarction and mortality prediction than CD4 count and HIV-1 RNA, concluding that current health determines risk more accurately than prior history.

Racial and ethnic differences in heart failure readmissions and mortality in a large municipal healthcare system.
This study sought to determine whether racial and ethnic differences exist among patients with similar access to care. It examined outcomes after heart failure hospitalization within a large municipal health system and determined that racial and ethnic differences in outcomes were present.

In-hospital measurement of left ventricular ejection fraction and one-year outcomes in acute coronary syndromes: results from the IMMEDIATE Trial.
The relationships between reduced left ventricular ejection fraction (LVEF) measured during index acute coronary syndrome (ACS) hospitalization and mortality and heart failure (HF) within 1 year are not well-defined. The researchers performed a retrospective analysis of 445 patients who had LVEF measured by left ventriculography or echocardiogram during hospitalization. They found that among patients with ACS, lower in-hospital LVEF is associated with increased 1-year mortality or hospitalization for HF.

Association between hospital performance on patient safety and 30-day mortality and unplanned readmission for Medicare fee-for-service patients with acute myocardial infarction.
The researchers studied the relationship between hospital performance on adverse event rates and hospital performance on 30-day mortality and unplanned readmission rates for Medicare fee-for-service patients hospitalized for acute myocardial infarction (AMI). They found that for Medicare fee-for-service patients discharged with AMI, hospitals with poorer patient safety performance were also more likely to have poorer performance on 30-day all-cause mortality and on unplanned readmissions.

National trends in heart failure hospitalization after acute myocardial infarction for Medicare beneficiaries: 1998-2010.
This study used a complete national sample of 2 789 943 AMI hospitalizations of Medicare fee-for-service beneficiaries from 1998 through 2010, we evaluated annual changes in the incidence of subsequent heart failure (HF) hospitalization and mortality using Poisson and survival analysis models. It found that HF hospitalization after AMI decreased from 1998 to 2010, which may indicate improvements in the management of AMI.

Geographic variation in trends and disparities in acute myocardial infarction hospitalization and mortality by income levels, 1999-2013.
The researchers sought to determine whether trends in US county-level, risk-standardized acute myocardial infarction (AMI) hospitalization and mortality rates varied by county-based median income level. They concluded that hospitalization and mortality rates of AMI declined among counties of all income levels, although hospitalization rates among low-income counties lag behind those of the higher income groups.

Association of HbA1c with hospitalization and mortality among patients with heart failure and diabetes.
Comorbid diabetes is common in heart failure and associated with increased hospitalization and mortality. Nonetheless, the association between glycemic control and outcomes among patients with heart failure and diabetes remains poorly characterized, particularly among low income and minority patients. This study found that among a cohort of primarily minority and low income patients with heart failure and diabetes, an increased risk of hospitalization was observed.

Incidence and in-hospital mortality of acute kidney injury (AKI) and dialysis-requiring AKI (AKI-D) after cardiac catheterization in the National Inpatient Sample.
This study examined cardiac catheterization or percutaneous coronary intervention (PCI) hospital discharges from the nationally representative National Inpatient Sample to determine annual population incidence rates for AKI and AKI-D in the United States from 2001 to 2011. It found that the incidence of AKI among cardiac catheterization and PCI patients has increased sharply in the United States; however, mortality has significantly declined.

Blood transfusion and 30-day mortality in patients with coronary artery disease and anemia following noncardiac surgery.
The researchers evaluated the association between postoperative blood transfusion and mortality in patients with coronary artery disease and postoperative MI following noncardiac surgery. Their findings support a restrictive postoperative transfusion strategy in patients with stable coronary artery disease following noncardiac surgery.

Comparative effectiveness of implantable cardioverter defibrillators for primary prevention in women.
The researchers examined clinical practice data to compare survival rates among women with heart failure with or without a primary prevention implantable cardioverter defibrillator (ICD). Theyn found that among patients with heart failure with reduced left ventricular ejection fraction, a primary prevention ICD was associated with a significant survival advantage among women and among men.
