Comparative StudyRisk-standardizing survival for in-hospital cardiac arrest to facilitate hospital comparisons.
The purpose of this study is to develop a method for risk-standardizing hospital survival after cardiac arrest. ⋯ We have derived and validated a model to risk-standardize hospital rates of survival for in-hospital cardiac arrest. Use of this model can support efforts to compare hospitals in resuscitation outcomes as a foundation for quality assessment and improvement.

Comparative StudyPost-mortem cardiac 3-T magnetic resonance imaging: visualization of sudden cardiac death?
This study aimed to investigate post-mortem magnetic resonance imaging (pmMRI) for the assessment of myocardial infarction and hypointensities on post-mortem T2-weighted images as a possible method for visualizing the myocardial origin of arrhythmic sudden cardiac death. ⋯ 3-T pmMRI visualizes chronic, subacute, and acute myocardial infarction in situ. In peracute infarction as a possible cause of sudden cardiac death, it demonstrates affected myocardial areas not visible on autopsy. pmMRI should be considered as a feasible post-mortem investigation technique for the deceased patient if no consent for a clinical autopsy is obtained.

Comparative StudyCoronary microvascular dysfunction and diastolic load correlate with cardiac troponin T release measured by a highly sensitive assay in patients with nonischemic heart failure.
This study investigated factors associated with cardiac troponin T (cTnT) release from failing myocardium. ⋯ cTnT release from failing myocardium correlated with diastolic load and coronary microvascular dysfunction in nonischemic HF patients.

Comparative StudyAssociations between routine coronary computed tomographic angiography and reduced unnecessary hospital admissions, length of stay, recidivism rates, and invasive coronary angiography in the emergency department triage of chest pain.
This study was designed to assess the effects on resource utilization of routine coronary computed tomographic angiography (CCTA) in triaging chest pain patients in the emergency department (ED). ⋯ The routine use of CCTA in ED evaluation of chest pain reduces healthcare resource utilization.
