Circulating magnesium as a potential risk stratification tool for sudden cardiac death: a systematic review.

Background: Sudden cardiac death (SCD) is one of the main causes of cardiovascular mortality and accounts for 15-20% of deaths worldwide. The current stratification strategy using depressed left ventricular ejection fraction is insufficient to stratify the risk of SCD, especially in the general population. In recent years, there has been increasing evidence showing the antiarrhythmic properties of magnesium.

Outcome in early vs late intubation among COVID-19 patients with acute respiratory distress syndrome: an updated systematic review and meta-analysis.

Timing of endotracheal intubation in COVID-19 patients with acute respiratory distress syndrome (ARDS) remains controversial regarding its risk and benefit in patient outcomes. Our study aims to elucidate early versus late intubation outcomes among COVID-19 patients with ARDS. A protocol of this study is registered at the international prospective register of systematic reviews (PROSPERO) (CRD42021230272).

Evaluation of subclinical ventricular systolic dysfunction assessed using global longitudinal strain in liver cirrhosis: A systematic review, meta-analysis, and meta-regression.

Global longitudinal strain (GLS) can identify subclinical myocardial dysfunction in patients with cirrhosis. This systematic review aims to provide evidence of a possible difference in GLS values between patients with cirrhosis and patients without cirrhosis. Studies from inception to August 11, 2021, were screened and included based on the inclusion criteria.

The Outcome of Ventricular Arrhythmias Associated With Mitral Valve Prolapse After Catheter Ablation: A Systematic Review and Meta-Analysis.

The presence of mitral valve prolapse (MVP) varies from asymptomatic to life-threatening arrhythmias. Catheter ablation (CA) is widely used to treat ventricular arrhythmias (VAs) associated with MVP. Despite having high procedural success, outcome data after CA is limited, especially in a long-term setting.

Current evidence for the risk of PR prolongation, QRS widening, QT prolongation, from lopinavir, ritonavir, atazanavir, and saquinavir: A systematic review.

Background: Lopinavir, ritonavir, atazanavir, and saquinavir had been reportedly used or suggested for coronavirus disease 2019 (COVID-19) treatment. They may cause electrocardiography changes. We aim to evaluate risk of PR prolongation, QRS widening, and QT prolongation from lopinavir, ritonavir, atazanavir, and saquinavir.

Current evidence of survival benefit between chest-compression only versus standard cardiopulmonary resuscitation in out-of-hospital cardiac arrest : Updated systematic review and meta-analysis of randomized controlled trials with trial sequential analysis.

Background: Evidence to support a better cardiopulmonary resuscitation method between standard vs. continuous chest compression (STD-CPR vs. CCC-CPR) is lacking.

[Patient selection for the implantation of a left atrial appendage occluder in primary and secondary prevention of cardioembolic stroke in atrial fibrillation].

The implantation of a left atrial appendage (LAA) occluder has evolved into an established non-pharmacological alternative to oral anticoagulation (OAC) in the prevention of cardioembolic stroke in patients with atrial fibrillation. While 2 randomized trials investigated the LAA occluder as an alternative treatment in patients who can also undergo OAC, current guidelines recommend the LAA occluder rather as a second line therapy if permanent OAC is not possible due to contraindications. This is in line with current practice where an LAA occluder is usually only implanted if OAC is contraindicated or stopped due to bleeding.

[Implantation of Watchman™ occluder of the left atrial appendage. Tips and tricks].

The implantation of an occluder system for the left atrial appendage (LAA) represents an interesting alternative for patients with atrial fibrillation and a CHA2DS2-VASc-Score ≥ 2 who cannot take permanent anticoagulation for various reasons. As in other left cardiac interventions, there are potentially dangerous possibilities for complications that can limit the advantages of this therapy. This overview summarizes practical tips and tricks at the implantation of a Watchman™ occluder which may help to minimize the complication rate.

Cardiac arrest and ventricular tachycardia in Japanese-type apical hypertrophic cardiomyopathy.

Apical hypertrophic cardiomyopathy (HCM) is a specific variant of HCM. This disease has been first described in Japan where the prevalence is much higher than in the western world. The prognosis of apical HCM with regard to sudden cardiac death is believed to be better than that of common HCM.
