The impact of the SARS-CoV-2 pandemic on in-hospital cardiac arrest: A systematic review and meta-analysis.

Background: There is an emerging concern regarding the indirect effect the Covid-19 pandemic has had on the care provided to patients. New resuscitation guidance including the donning of Personal Protective Equipment before commencing resuscitation efforts, the avoidance of bag-mask ventilation, limiting the number of responders and stopping resuscitation efforts earlier could have led to worse outcomes following in-hospital cardiac arrest (IHCA) when compared to the non-pandemic period. The primary objective was to understand the impact of the pandemic on patient outcomes following IHCA by comparing the pandemic and non-pandemic periods.

Factors predicting mortality in the cardiac ICU during the early phase of targeted temperature management in the treatment of post-cardiac arrest syndrome - The RAPID score.

Introduction: Survival rates after out-of-hospital cardiac arrest (OHCA) remain low, and early prognostication is challenging. While numerous intensive care unit scoring systems exist, their utility in the early hours following hospital admission, specifically in the targeted temperature management (TTM) population, is questionable. Our aim was to create a score system that may accurately estimate outcome within the first 12 h after admission in patients receiving TTM.

Non-invasive myocardial work as an independent predictor of postprocedural NT-proBNP in elderly patients undergoing transcatheter aortic valve replacement.

Aortic stenosis has become the most prevalent valvular disease with increasing life expectancy and the ageing of the population, representing a significant clinical burden for health care providers. Its treatment has been revolutionized by transcatheter aortic valve replacement (TAVR) as a safe and minimally invasive option for elderly patients. Left ventricular (LV) functional measurement is of particular importance before TAVR, however, increased afterload significantly influences the conventional echocardiographic parameters.

A Comparative Investigation of the Pulmonary Vasodilating Effects of Inhaled NO Gas Therapy and Inhalation of a New Drug Formulation Containing a NO Donor Metabolite (SIN-1A).

Numerous research projects focused on the management of acute pulmonary hypertension as Coronavirus Disease 2019 (COVID-19) might lead to hypoxia-induced pulmonary vasoconstriction related to acute respiratory distress syndrome. For that reason, inhalative therapeutic options have been the subject of several clinical trials. In this experimental study, we aimed to examine the hemodynamic impact of the inhalation of the SIN-1A formulation (N-nitroso-N-morpholino-amino-acetonitrile, the unstable active metabolite of molsidomine, stabilized by a cyclodextrin derivative) in a porcine model of acute pulmonary hypertension.

Key influences of VDD (DX) ICD selection: Results from a prospective, national survey.

Background: To preserve the benefit of atrial sensing without the implantation of an additional lead, a single-lead ICD system with a floating atrial dipole (DX ICD) has been developed. The purpose of this nationwide survey was to provide an overview of the current key influences of device selection focusing on DX ICD and to test the applicability of a previously published decision-making flowchart of ICD-type selection.

Methods: An online questionnaire was sent to all implanting centers in Hungary.

Non-invasive assessment of left ventricular contractility by myocardial work index in veno-arterial membrane oxygenation patients: rationale and design of the MIX-ECMO multicentre observational study.

Introduction And Aims: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is an increasingly utilized therapeutic choice in patients with cardiogenic shock, however, high complication rate often counteracts with its beneficial cardiopulmonary effects. The assessment of left ventricular (LV) function in key in the management of this population, however, the most commonly used measures of LV performance are substantially load-dependent. Non-invasive myocardial work is a novel LV functional measure which may overcome this limitation and estimate LV function independent of the significantly altered loading conditions of VA-ECMO therapy.

The investigation of the efficiency of basic life support education among high school students: Protocol, design and implementation of an interventional, prospective longitudinal, individually randomised, parallel 1:1 grouped trial.

Background: Basic life support (BLS) skills are crucial not only for healthcare workers but for all lay people as well. Timely recognition of out-of-hospital cardiac arrest (OHCA) and the initiation of BLS by bystanders before the arrival of healthcare personnel may improve survival. There are several methods of spreading BLS skills and improve BLS skill retention among lay people.

The prevalence of frailty and its effect on the outcome in cardiac resynchronization therapy patients.

Frailty is a complex clinical syndrome associated with aging and comorbidities, which correlates with unfavorable outcomes. However, in heart failure patients, frailty is very common, data is scarce about those, who are eligible for Cardiac Resynchronization Therapy (CRT) implantation. We investigated the incidence of frailty and the association of Frailty Index (FI) with the outcome.

Acute coronary syndrome associated cardiogenic shock in the catheterization laboratory: peripheral veno-arterial extracorporeal membrane oxygenator management and recommendations.

Cardiogenic shock (CS) in acute coronary syndrome (ACS) is a critical disease with high mortality rates requiring complex treatment to maximize patient survival chances. Emergent coronary revascularization along with circulatory support are keys to saving lives. Mechanical circulatory support may be instigated in severe, yet still reversible instances.

Phenogrouping and risk stratification of patients undergoing cardiac resynchronization therapy upgrade using topological data analysis.

Choosing the optimal device during cardiac resynchronization therapy (CRT) upgrade can be challenging. Therefore, we sought to provide a solution for identifying patients in whom upgrading to a CRT-defibrillator (CRT-D) is associated with better long-term survival than upgrading to a CRT-pacemaker (CRT-P). To this end, we first applied topological data analysis to create a patient similarity network using 16 clinical features of 326 patients without prior ventricular arrhythmias who underwent CRT upgrade.

Time-trend treatment effect of cardiac resynchronization therapy with or without defibrillator on mortality: a systematic review and meta-analysis.

Aims: This study aimed to investigate the impact of cardiac resynchronization therapy with a defibrillator (CRT-D) on mortality, comparing it with CRT with a pacemaker (CRT-P). Additionally, the study sought to identify subgroups, evaluate the time trend in treatment effects, and analyze patient characteristics, considering the changing indications over the past decades.

Methods And Results: PubMed, CENTRAL, and Embase up to October 2021 were screened for studies comparing CRT-P and CRT-D, focusing on mortality.

Upgrade of right ventricular pacing to cardiac resynchronization therapy in heart failure: a randomized trial.

Background And Aims: De novo implanted cardiac resynchronization therapy with defibrillator (CRT-D) reduces the risk of morbidity and mortality in patients with left bundle branch block, heart failure and reduced ejection fraction (HFrEF). However, among HFrEF patients with right ventricular pacing (RVP), the efficacy of CRT-D upgrade is uncertain.

Methods: In this multicentre, randomized, controlled trial, 360 symptomatic (New York Heart Association Classes II-IVa) HFrEF patients with a pacemaker or implantable cardioverter defibrillator (ICD), high RVP burden ≥ 20%, and a wide paced QRS complex duration ≥ 150 ms were randomly assigned to receive CRT-D upgrade (n = 215) or ICD (n = 145) in a 3:2 ratio.

Topological data analysis to identify cardiac resynchronization therapy patients exhibiting benefit from an implantable cardioverter-defibrillator.

Background: Current guidelines recommend considering multiple factors while deciding between cardiac resynchronization therapy with a defibrillator (CRT-D) or a pacemaker (CRT-P). Nevertheless, it is still challenging to pinpoint those candidates who will benefit from choosing a CRT-D device in terms of survival.

Objective: We aimed to use topological data analysis (TDA) to identify phenogroups of CRT patients in whom CRT-D is associated with better survival than CRT-P.

Early Application of ECMO after Sudden Cardiac Arrest to Prevent Further Deterioration: A Review and Case Report.

ECMO has become a therapeutic modality for in- and out-of-hospital scenarios and is also suitable as a bridging therapy until further decisions and interventions can be made. Case report: A 27-year-old male patient with mechanical aortic valve prothesis had a sudden cardiac arrest (SCA). ROSC had been achieved after more than 60 min of CPR and eight DC shocks due to ventricular fibrillation (VF).

Remote Management of Patients with Cardiac Implantable Electronic Devices during the COVID-19 Pandemic.

Remote monitoring (RM) is the newest function of cardiac implantable electronic devices (CIEDs). In our observational retrospective analysis, we aimed to assess whether telecardiology could be a safe alternative to routine outpatient examinations during the COVID-19 pandemic. The in- and outpatient visits, the number of acute cardiac decompensation episodes, the RM data from CIEDs, and general condition were examined via questionnaires (KCCQ, EQ-5D-5L).

[The novelties of adult advanced life support and post-resuscitation therapy].

The fourth element of chain-of-survival contains advanced life support and post-resuscitation treatment. Both treatment options influence the outcome of patients suffering cardiac arrest. Advanced life support includes all interventions that require special medical equipment and expertise.

[The role of extracorporeal life support in cardiopulmonary resuscitation].

The frequency of the administration of extracorporeal cardiopulmonary resuscitation is increasing both in the treatment of in-hospital and out-of-hospital cardiac arrest. The latest resuscitation guidelines support the use of mechanical circulatory support devices in the cases of prolonged cardiopulmonary resuscitation in certain selected patient groups. However, only little evidence is available regarding the effectiveness of extracorporeal cardiopulmonary resuscitation, and many open questions remained unanswered regarding the adequate conditions of this modality.

[Rhythm and rate control in the context of resuscitation and periarrest states].

Cardiovascular mortality has declined significantly in recent years, however, sudden cardiac death remains the leading cause of death in a range of different mortality indicators, very often caused by cardiac arrhythmias. The electrophysiological causes of sudden cardiac death include ventricular tachycardia, ventricular fibrillation, asystole and pulseless electrical activity. In addition, other cardiac arrhythmias may also trigger sudden cardiac death, periarrest arrhytmias.

[Impact of the COVID-19 pandemic on basic resuscitation and success rate after sudden cardiac arrest].

Since the onset of the coronavirus disease, infection-related mortality has been tracked worldwide and the number of deaths caused by the virus is counted daily. The coronavirus pandemic has not only transformed our daily life, but reorganized the whole healthcare system. In response to the increased demand for hospital admissions, leaders in different countries have implemented a number of emergency actions.

[Cardiopulmonary resuscitation in special circumstances].

The standard process of basic and advanced life support can be complicated by a number of special circumstances. Over the last decade, the European Resuscitation Council developed an increasingly detailed guideline regarding the diagnosis and therapy of these situations. In our short review, we summarize the most important recommendations for the management of cardiopulmonary resuscitation in special circumstances.

Direct Oral Anticoagulants as the First Choice of Anticoagulation for Patients with Peripheral Artery Disease to Prevent Adverse Vascular Events: A Systematic Review and Meta-Analysis.

The best method of anticoagulation for patients with peripheral artery disease (PAD) is still a topic of interest for physicians. We conducted a meta-analysis to compare the effects of direct oral anticoagulants (DOACs) with those of vitamin-K-antagonist (VKA) anticoagulants in patients with peripheral artery disease. Five databases (Medline (via PubMed), EMBASE, Scopus, Web of Science, and CENTRAL) were searched systematically for studies comparing the effects of the two types of anticoagulants in patients with PAD, with an emphasis on lower-limb outcomes, cardiovascular events, and mortality.
