Contemporary Management and Prognostic Factors of Arrhythmia Recurrence in Patients with High-Energy Discharge of Cardiac Implantable Electronic Devices.

: Understanding the underlying causes of implantable cardioverter-defibrillator (ICD) discharges is vital for effective management. This study aimed to evaluate the characteristics of patients admitted following ICD discharge, focusing on myocardial ischemia as a potential exacerbating factor and potential risk factors for VT recurrence. : This retrospective, single-center study included 81 patients with high energy discharge from cardiac implantable electronic device admitted urgently to the cardiology department from 2015 to 2022.

Wide Spectrum of Bradyarrhythmias and Supraventricular Tachyarrhythmias in Sportsmen: Run Forrest, Run?!

The intricate relationship between sports participation and cardiac arrhythmias is a key focus of cardiovascular research. Physical activity, integral to preventing atherosclerotic cardiovascular disease, induces structural, functional, and electrical changes in the heart, potentially triggering arrhythmias, particularly atrial fibrillation (AF). Despite the cardiovascular benefits, the optimal exercise amount remains unclear, revealing a J-shaped association between AF and exercise.

Evaluation of the pharmacotherapeutic impact on contractility recovery in patients with newly diagnosed, acute onset dilated cardiomyopathy.

In patients with acute onset dilated cardiomyopathy (DCM) an improvement of left ventricular ejection fraction (LVEF) can occur as an effect of complex therapy. The aim of the study was to evaluate a pharmacotherapeutic impact on LVEF recovery in newly diagnosed DCM heart failure (HF) patients. A total of 2436 patients hospitalized due to acute decompensated HF were retrospectively analyzed.

Heart Failure with Improved Ejection Fraction: Insight into the Variable Nature of Left Ventricular Systolic Function.

The progress of contemporary cardiovascular therapy has led to improved survival in patients with myocardial disease. However, the development of heart failure (HF) represents a common clinical challenge, regardless of the underlying myocardial pathology, due to the severely impaired quality of life and increased mortality comparable with malignant neoplasms. Left ventricular ejection fraction (LVEF) is the main index of systolic function and a key predictor of mortality among HF patients, hence its improvement represents the main indicator of response to instituted therapy.

Cardiac implantable electronic devices procedures and their recipients characteristic during COVID-19 pandemic: 3.8 million population analysis.

Background: Coronavirus disease 2019 (COVID-19) pandemic disorganised healthcare systems and has caused a reduction in the number of hospitalizations and procedures. Cardiac implantable electronic device (CIED) procedure rates and clinical characteristics of their recipients were compared in corresponding weeks of 2019 and 2020 were analyzed.

Methods: The database of the National Health Fund (NHF) in Poland was retrospectively analyzed.

The usefulness of telemedicine devices in patients with severe heart failure with an implanted cardiac resynchronization therapy system during two years of observation.

Background: Heart failure (HF) remains a disease with a poor prognosis. Telemonitoring is a medical service aimed at remote monitoring of patients.

Aim: The study aimed to identify the clinical relevance of non-invasive telemonitoring devices in HF patients.

Transient out-of-range impedance in "hybrid" implantable cardioverter-defibrilator system: A case series.

A retrospective analysis of 60 patients with hybrid implantable cardioverter-defibrilator (ICD) systems: Boston Scientific device paired with non-Boston leads. In 10 (17%) patients transient, out-of-range peaks of ventricular pace impedance trend were observed. Probable cause is header-lead interaction incompatibility.

Left ventricular global longitudinal strain in predicting CRT response: one more J-shaped curve in medicine.

The aim of the study was: (1) to verify the hypothesis that left ventricular global longitudinal strain (LVGLS) may be of additive prognostic value in prediction CRT response and (2) to obtain such a LVGLS value that in the best optimal way enables to characterize potential CRT responders. Forty-nine HF patients (age 66.5 ± 10 years, LVEF 24.

Regional Strain Pattern Index-A Novel Technique to Predict CRT Response.

Background: Cardiac resynchronization therapy (CRT) improves outcome in patients with heart failure (HF) however approximately 30% of patients still remain non-responsive. We propose a novel index-Regional Strain Pattern Index (RSPI)-to prospectively evaluate response to CRT.

Methods: Echocardiography was performed in 49 patients with HF (66.

Risk factors and prognostic role of an electrical storm in patients after myocardial infarction with an implanted ICD for secondary prevention.

Introduction: The aim of our study was to determine the risk factors for electrical storm (ES) and to assess the impact of ES on the long-term prognosis in patients after myocardial infarction (MI) with an implantable cardioverter-defibrillator (ICD) for secondary prevention of sudden cardiac death (SCD).

Material And Methods: We retrospectively analyzed 416 patients with coronary artery disease after MI who had an implanted ICD for secondary prevention of SCD. Fifty (12%) patients had one or more incidents of an electrical storm - the ES (+) group.

A study to evaluate the prevalence and determinants of stress coping strategies in heart failure patients in Poland (CAPS-LOCK-HF sub-study).

Background And Aim: We aimed to evaluate the prevalence and determinants of different stress coping strategies in Polish patients suffering from heart failure with reduced ejection fraction (HFREF).

Methods: This manuscript is a sub-study of the CAPS-LOCK-HF multicentre psychological status assessment of patients with HFREF. Patients with > six-month history of HFREF and clinical stability for ≥ three months and left ventricular ejection fraction (LVEF) < 45% were enrolled in the study.

Differences of psychological features in patients with heart failure with regard to gender and aetiology - Results of a CAPS-LOCK-HF (Complex Assessment of Psychological Status Located in Heart Failure) study.

Objective: Objective of the study was to assess the psychological state of HF patients with reduced ejection fraction (HFrEF) with regard to gender and aetiology.

Methods: 758 patients with HFrEF (mean age - 64±11years, men - 79%, NYHA class III-IV - 40%, ischemic aetiology - 61%) in a prospective Polish multicenter Caps-Lock-HF study. Scores on five different self-report inventories: CISS, MHLC, GSES, BDI and modified Mini-MAC were compared between the sexes taking into account the aetiology of HFrEF.

Heart rate turbulence in postinfarction patients with history of malignant ventricular arrhythmias.

Unlabelled: In the study, there has been retrospectively analyzed heart rate turbulence in postinfarction patients. The cohort of 158 patients consisted of 94 patients with documented ventricular tachycardia and/or ventricular fibrillation (VT/VF) and 64 patients without history of VT/VF. Turbulence onset and slope were calculated from Holter recordings, and left ventricle ejection fraction (LVEF) ≤35% was regarded as severe left ventricle dysfunction.
