Risk-adjusted in-hospital mortality models for congestive heart failure and acute myocardial infarction: Value of clinical laboratory data and race/ethnicity.
This study examined the impact of key laboratory and race/ethnicity data on the prediction of in-hospital mortality for congestive heart failure (CHF) and acute myocardial infarction (AMI). It found that adding a simple three-level summary measure based on the number of abnormal laboratory data observed to hospital administrative claims data significantly improved the model prediction for inpatient mortality.

Effect of race on outcomes (stroke and death) in patients >65 years with atrial fibrillation.
The researchers sought to determine whether there are any racial differences in the outcomes of death and stroke in patients with newly diagnosed AF in patients >65 years. They found that the risks of death and stroke are higher in blacks and Hispanics compared with whites. The increased risk was eliminated or significantly reduced after adjusting for preexisting co-morbidities.

Can adding laboratory values improve risk-adjustment mortality models using clinical percutaneous cardiac intervention registry data?
The authors predicted in-hospital/30-day mortality with and without appended laboratory data using New York's percutaneous coronary intervention registry data from 2008-2010. They found that adding laboratory data did not significantly improve the risk-adjustment mortality models' performance and did not dramatically change the quality assessment of hospitals.

Cumulative incidence of death and rehospitalization among the elderly in the first year after NSTEMI.
The researchers evaluated mortality and cause-specific rehospitalization rates in elderly non-ST-segment elevation myocardial infarction survivors with ischemic heart disease. They found that rehospitalization rates do not rise substantially with advancing age, and rehospitalization is often for noncardiac diagnoses.

Effect of present-on-admission (POA) reporting accuracy on hospital performance assessments using risk-adjusted mortality.
This study evaluated how the accuracy of present-on-admission (POA) reporting affects hospital 30-day acute myocardial infarction (AMI) mortality assessments. It finds that the use of POA indicators in administrative data significantly alters risk-adjusted hospital assessments that do not incorporate a method for distinguishing between comorbidities and complications.

Impact of gait speed and instrumental activities of daily living on all-cause mortality in adults >/=65 years with heart failure.
This study investigated the impact of gait speed and IADL, separately and combined, on all-cause mortality in adults with incident heart failure who are >65 years. It found that the combined presence of slower gait speed and Instrumental Activities of Daily Living (IADL) impairment was associated with a greater risk of mortality and suggested an additive relation between gait speed and IADL.

Perfect storm: concurrent stress and depressive symptoms increase risk of myocardial infarction or death.
A recently offered psychosocial perfect storm conceptual model hypothesizes amplified risk will occur in those with concurrent stress and depressive symptoms. The authors tested this hypothesis in a large sample of US adults with coronary heart disease. They found that those with low stress and high depressive symptoms or high stress and low depressive symptoms were not at increased risk, while participants with concurrent high stress and high depressive symptoms had increased risk for myocardial infarction or death relative to those with low stress and low depressive symptoms. They concluded that their results provide initial support for a psychosocial perfect storm conceptual model.

Association of left ventricular systolic function and vasopressor support with survival following pediatric out-of-hospital cardiac arrest.
This study characterizes the association of hospital discharge survival with left ventricular systolic function evaluated by transthoracic echocardiography and vasoactive infusion support following return of spontaneous circulation after pediatric out-of-hospital cardiac arrest. It found that in patients receiving transthoracic echocardiography within the first 24 hours, decreased left ventricular systolic function and vasopressor use were common.
