Background and Aims Higher levels of stress impact the prevalence metabolic syndrome (MetS) coronary heart disease. The association between MetS, impaired pulmonary function low level physical activity is still pending assessment in subjects exposed to stress. study aimed examine whether higher might be related MetS plaque presence, as well affect function. Design Methods embraced 235 police officers (mean age 40.97 years) from south Poland. anthropometrics biochemical variables were...

To analyze and compare the effectiveness safety of transvenous lead extraction (TLE) implantable cardioverter-defibrillator (ICD) leads with a dwell time >10 years (Group A) vs. younger B) using mechanical systems.Between October 2011 July 2022, we performed TLE in 318 patients. Forty-six (14.4%) extracted ICD 46 (14.5%) patients that had been implanted for years. The median all was 5.9 Cardiovascular electronic device-related infection an indication 31.8% Complete removal complete...

Abstract Aims A novel therapy offering cardiac resynchronization (CRT) with an additional lead placed in His bundle has been reported a few case reports and series as improving the hemodynamical clinical condition of patients permanent atrial fibrillation (AF) whom other therapeutic methods have not successful. Methods Fourteen consecutive AF, heart failure (HF), branch block (BBB) QRS complex width >130 ms, impaired left ventricular ejection fraction (LVEF) underwent implantation...

Introduction: Heart perforation is a rare complication of pacemaker (PM)/im plantable cardioverter-defibrillator (ICD) implantation.Material and methods: In our clinic in 2005-2010, 6 patients with heart were hospitalized (3 women, 3 men), mean age 58.6 ±20.8 years (17 to 73 years).The indication PM/ICD implantation was tachy-brady syndrome cases, second-degree atrioventricular block, advanced losses consciousness, vaso-vagal type II B asystole lasting 12 s recurrent non-sustained...

IntroductIon Atrial fibrillation (AF) is the most common cardiac arrhythmia.AF associated with a prothrombotic state reflected by elevated thrombin generation markers, including F1 + 2 prothrombin fragments, or D-dimer. 1,2 It has also been shown that increased levels of plasminogen activator inhibitor 1 (PAI-1) occur in patients AF. 3 Other hypercoagulability markers detected permanent AF involved plasma fibrinogen, von Willebrand factor, and soluble P-selectin. 4 well known an risk stroke...

We investigated whether growth differentiation factor-15 (GDF-15), also known as macrophage inhibitory cytokine-1 (MIC-1), levels are associated with a prothrombotic state in atrial fibrillation (AF) compared to N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin I (cTnI-hs). In 103 patients AF assessed off anticoagulation (age: 71.0 [65.0–76.0] years; CHA2DS2-VASc score: 4.6 ± 1.7), we measured endogenous thrombin potential (ETP), plasma fibrin clot...

Background: Pacing leads remain the weakest link in pacemaker systems despite advances manufacturing technology. Aim: The aim of study was to assess long-term pacing lead performance an unselected real-life cohort following primary DDD system implantation. Methods: A single-centre retrospective analysis patients who underwent implantation between October 1984 and December 2014 were followed-up until August 2016 conducted. inclusion criterion at least one follow-up visit after post-implant...

Venous stenosis and occlusion in the presence of endocardial leads constitute one complications permanent cardiac pacing either by pacemaker, implantable cardioverter-defibrillator or resynchronization therapy.The aim this study was to assess incidence occlusions determine risk factors patients with a prospective single-center study.Two hundred eighty consecutive aged 25-95 years (male 68.8%) were included. A contrast venography examination ipsilateral access vein performed. The whole...

It is unclear whether chronic kidney disease (CKD) increases thromboembolism in atrial fibrillation (AF). We conducted a retrospective cross-sectional analysis of 502 non-anticoagulated AF patients (median age, 66 (60-73) years, median CHA2DS2-VASc score, 3.0 (2.0-4.0)) with an estimated glomerular filtration rate (eGFR) ≥ 15 mL/min/1.73 m2. Endogenous thrombin potential (ETP), clot permeability (Ks), and lysis time (CLT), among others, were determined. Patients stage 4 CKD (n = 87; 17.3%)...

Lead-dependent infective endocarditis (LDIE) is a life-threatening complication of permanent transvenous cardiac pacing. According to the 2015 European Society Cardiology (ECS) guidelines, diagnosis LDIE based on modified Duke criteria (MDC), while single-photon emission computed tomography with conventional (SPECT-CT) radioisotope-labeled leukocytes serves as an additional tool in difficult cases. The major challenge differentiate between true vegetation and thrombus.The aim study was...

Background: Implantable cardioverter-defibrillator (ICD) therapy is current the main approach to prevent sudden cardiac death. It was demonstrated that patients with ICD are characterised by worse quality of life (QOL) and exercise capacity prone depressive symptoms. Thus, comprehensive rehabilitation indicated in recipients. Aim: To evaluate safety benefits early after implantation. Methods: The study group consisted 45 (28 males, mean age 62.2 years) whom a program initiated at 6 weeks...
