Comparative Study
Combination evaluation of preoperative risk indices predicts requirement of biventricular assist device.
Patients with biventricular assist device (BiVAD) placement have a poor prognosis, but preoperative risk factors for the necessity of BiVAD have not been fully elucidated. ⋯ The new scoring method, which includes CVP/PCWP ratio, is a novel risk stratification tool for BiVAD therapy.

Clinical Trial
Sleep-disordered breathing is an independent risk factor of aborted sudden cardiac arrest in patients with coronary artery spasm.
Sleep-disordered breathing (SDB) is often associated with sudden cardiac arrest (SCA) during sleep. Coronary artery spasm (CS) also occurs during sleep and is rarely associated with SCA, but the role of SDB in the risk of SCA is unknown in CS patients. This study evaluated the breathing patterns during sleep in CS patients with a prior history of aborted SCA. ⋯ SDB is a significant risk factor for SCA in CS patients and autonomic instability during sleep might be involved in this association.

Randomized Controlled Trial
Effects of remote ischemic preconditioning with postconditioning in patients undergoing off-pump coronary artery bypass surgery--randomized controlled trial.
Myocardial injury is associated with an adverse outcome after off-pump coronary artery bypass graft surgery (OPCAB). The authors conducted a randomized controlled trial to evaluate whether remote ischemic preconditioning (RIPC) with remote ischemic postconditioning (RIPostC) reduces myocardial injury in patients undergoing OPCAB. ⋯ RIPC+RIPostC by lower limb ischemia decreased postoperative myocardial enzyme elevation by almost half postoperatively in patients undergoing OPCAB.

The purpose of this study was to determine whether a low-dose β-blocker, in combination with milrinone, improves cardiac function in acute decompensated heart failure (ADHF) with tachycardia. ⋯ A low-dose β-blocker in combination with milrinone improved cardiac function in ADHF patients with tachycardia; therefore, it may be considered as an adjunct therapy for use when standard therapy with milrinone is not effective at slowing HR.
