Comparative Study Observational Study
Predictors of survival and favorable functional outcomes after an out-of-hospital cardiac arrest in patients systematically brought to a dedicated heart attack center (from the Harefield Cardiac Arrest Study).
Despite advances in cardiopulmonary resuscitation (CPR), survival remains low after out-of-hospital cardiac arrest (OOHCA). Acute coronary ischemia is the predominating precipitant, and prompt delivery of patients to dedicated facilities may improve outcomes. Since 2011, all patients experiencing OOHCA in London, where a cardiac etiology is suspected, are systematically brought to heart attack centers (HACs). ⋯ Consistent predictors of increased mortality were the presence of cardiogenic shock, advanced airway use, increased duration of resuscitation, and absence of therapeutic hypothermia. A streamlined delivery of patients experiencing OOHCA to dedicated facilities is associated with improved functional status and survival. Our study supports the standardization of care for such patients with the widespread adoption of HACs.

Multicenter Study Comparative Study
Relation of atrial fibrillation and right-sided cardiac thrombus to outcomes in patients with acute pulmonary embolism.
Atrial fibrillation (AF) can induce a hypercoagulable state in both the left and right atria. Thrombus in the right side of the heart (RHT) may lead to acute pulmonary embolism (APE). The aim of the study was to determine the prevalence of RHT and AF and to assess their impact on outcomes in patients with APE. ⋯ In multivariate analysis, RHT (p = 0.03) was an independent predictor of death. In conclusion, AF is a frequent co-morbidity in patients with APE, and the presence of RHT is not uncommon. Among patients with APE, the presence of RHT increases the mortality approximately threefold regardless of the presence of known AF.

The American Heart Association (AHA) and the American College of Cardiology (ACC) have recently updated their joint guidelines for the management of patients with non-ST-elevation acute coronary syndromes (NSTE-ACS, including unstable angina [UA] and non-ST-elevation myocardial infarction [NSTEMI]). These guidelines replace the 2007 guidelines and the focused updates from 2011 and 2012 and now combine UA and NSTEMI into a new classification, NSTE-ACS, and updating the terminology around noninvasive management to ischemia-guided strategy. ⋯ Also, where appropriate, similarities and differences between the current recommendations of the AHA/ACC and those of the European Society of Cardiology (ESC) are highlighted. For example, the AHA/ACC recommends the P2Y12 inhibitor ticagrelor over clopidogrel in all patients with NSTE-ACS and clopidogrel, prasugrel, or ticagrelor for patients in whom percutaneous coronary intervention is planned, whereas the ESC guidelines specifically recommend individual P2Y12 inhibitors for particular patient subgroups.

Current guidelines recommend shorter door-to-balloon times (DBTs) (<90 minutes) for patients with ST-elevation myocardial infarction (STEMI). Clinical factors, including patient or hospital characteristics, associated with prolonged DBT have been identified, but angiographic variables such as culprit lesion location have not been thoroughly investigated. We aimed to evaluate the effect of culprit artery location on DBT of patients with STEMI who underwent percutaneous coronary intervention (PCI). ⋯ Multivariate logistic regression analysis revealed that the LC location was an independent predictor for DBT >90 minutes (odds ratio, 1.45; 95% confidence interval, 1.04 to 2.01; p = 0.028). In conclusion, LC location was an independent predictor of longer DBT. The difficulties in diagnosing LC-related STEMI need further evaluation.

Patients admitted to today's cardiac intensive care units (CICUs) have increasingly complex medical conditions; consequently, palliative care is becoming an integral component of their care. Although there is a robust body of literature emanating from other intensive care unit settings, there has been less discussion about the role of palliative care in the CICU. This study examined all admissions to the Mount Sinai Hospital CICU from January 1 through December 31, 2012. ⋯ There was no difference in CICU length of stay or days to mortality from the time of CICU admission between the 2 groups. In conclusion, our study demonstrates the effect of palliative care and end-of-life decision making in the CICU. As such, we advocate for increased palliative care education and training among clinicians who are involved in cardiac critical care.
