ReviewThe hospital's role in improving survival of patients with out-of-hospital cardiac arrest.
Out-of-hospital cardiac arrest (OHCA) is a major public health problem. Unfortunately, in spite of recurring updated guidelines, survival of patients with OHCA had been unchanged for decades. ⋯ These centers are committed to the treatment of post-cardiac arrest syndrome by providing 24/7 therapeutic mild hypothermia, urgent cardiac catheterization and percutaneous coronary intervention, evidence-based termination of resuscitation protocols that limit premature withdrawal of care, protocol to address organ donation, commitment of cardiocerebral resuscitation training in their community, and a commitment and proven ability of data collection to assure that instituted changes result in improved survival. This newer aspect of hospital practice is an aspect that needs to be embraced by either becoming a Cardiac Receiving Center or partnering with other hospitals that can provide this critically important service.

Predictive value of preoperative electrocardiography for perioperative cardiovascular outcomes in patients undergoing noncardiac, nonvascular surgery.
The utility of routine preoperative electrocardiography (ECG) for assessing perioperative cardiovascular risk in patients undergoing noncardiac, nonvascular surgery (NCNVS) is unclear. ⋯ Prolongation of the QTc interval on the preoperative ECG was related with PCE in patients undergoing NCNVS.

Pretreatment with low-dose β-adrenergic antagonist therapy does not affect severity of Takotsubo cardiomyopathy.
Takotsubo cardiomyopathy is a syndrome of transient left ventricular dysfunction following acute emotional or physical stress without obstructive coronary artery disease. The leading hypothesis for the etiology is stress-induced catecholamine surge. ⋯ Prior therapy with low-dose β-adrenergic antagonists does not affect the severity of presentation and clinical course of Takotsubo cardiomyopathy as measured by common markers of myocardial dysfunction.
