Multicenter Study Comparative Study
Long-term comparison of cryoballoon and radiofrequency ablation of paroxysmal atrial fibrillation: a propensity score matched analysis.
Although radiofrequency (RF) and cryoballoon (CB) based technologies for pulmonary vein isolation (PVI) have both individually been demonstrated to be effective and safe for the treatment of paroxysmal AF, head-to-head comparisons are lacking. The purpose of this study was to compare the outcome of cryoballoon versus radiofrequency ablation in patients with paroxysmal atrial fibrillation undergoing pulmonary vein isolation. ⋯ A propensity score matched comparison between CB-PVI and RF-PVI using a 3D-mapping system for AF ablation showed similar long-term success rates.

Despite the fact that recent evidence from meta-analysis of randomized trials indicates an increase in mortality, perioperative treatment with β-blockers is still widely advocated. We therefore performed a meta-analysis of cohort studies to evaluate the effects of perioperative β-blockers on mortality in patients undergoing non-cardiac surgery in the real world scenarios. ⋯ In the real world scenarios, for patients undergoing non-cardiac surgery, the routine use of β-blockers does not seem to reduce the risk of death. Moreover, those who are taking β-blockers on the day of surgery may have an increased risk of postoperative mortality. However, these results should be interpreted with caution because of the significant heterogeneity across the studies.

Multicenter Study Comparative Study
One-year clinical outcomes of everolimus- versus sirolimus-eluting stents in patients with acute myocardial infarction.
In contrast to many studies comparing everolimus-eluting stent (EES) with paclitaxel-eluting stent (PES), data directly comparing EES with sirolimus-eluting stent (SES) are limited, especially in patients with acute myocardial infarction (AMI). ⋯ The present propensity score matched analysis performed in a large-scale, prospective, multicenter registry suggests that the second-generation drug-eluting stent EES has at least comparable or even better safety and efficacy profiles as compared with SES in the setting of AMI.

Recent guidelines for treating ventricular fibrillation (VF) and ventricular tachycardia (VT) stress class III antiarrhythmic drugs, but some malignant arrhythmias refractory to these agents still occur in clinical practice. The possibility of a new treatment strategy involving lidocaine and amiodarone combination therapy was evaluated. ⋯ This retrospective study suggests that combination therapy with lidocaine and amiodarone can terminate most refractory ventricular arrhythmias. Even in patients with a sufficient LVEF not receiving amiodarone, it is possible that lidocaine can contribute to a favorable outcome.
