Medical Costs and Economic Impact of Hyperkalemia in a Cohort of Heart Failure Patients with Reduced Ejection Fraction.

: Hyperkalemia is a common electrolyte disorder in patients with heart failure and reduced ejection fraction (HFrEF). Renin-angiotensin-aldosterone system inhibitors (RAASi) have been shown to improve survival and decrease hospitalization rates, although they may increase the serum potassium levels. Hyperkalemia has significant clinical and economic implications, and is associated with increased healthcare resource utilization.

Pacing system analyzers to guide conduction system pacing implantation procedures: A comparison study of intracardiac and surface signals with an electrophysiology recording system.

Background: Left bundle branch area pacing (LBBAP) needs confirmation of left conduction system capture assessed by testing of different electrical parameters. Guidelines recommend the use of an electrophysiology recording system (EP-RS) to guide conduction system pacing procedures. However, some experienced centers perform LBBAP procedures without an EP-RS.

Spanish catheter ablation registry. 23rd official report of the Heart Rhythm Association of the Spanish Society of Cardiology (2023).

Introduction And Objectives: We report the results of the 2023 Spanish catheter ablation registry.

Methods: Procedural data were collected and incorporated into the REDCap platform by all participating centers through a specific form.

Results: There were 104 participating centers in 2023 compared with 103 in 2022.

Health-Related Quality of Life and Satisfaction in Atrial Fibrillation Patients on Anticoagulant Therapy: Differences between Vitamin K Antagonists and Direct Oral Anticoagulants; Results from the Multicentre REGUEIFA Registry.

: Oral anticoagulation (OAC) is pivotal in the clinical management of atrial fibrillation (AF) patients. Vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs) prevent thromboembolic events, but information about the quality of life (QoL) and patient satisfaction in relation with the anticoagulant treatment is limited. : REGUEIFA is a prospective, observational, and multicentre study that included patients with AF treated by cardiologists.

Impact of Hyperkalemia in Heart Failure and Reduced Ejection Fraction: A Retrospective Study.

(1) Background: Hyperkalemia is a common finding in patients with heart failure and reduced ejection fraction (HFrEF), though its prognostic significance is controversial. There is no consensus on optimal potassium levels in these patients. The primary endpoint of this study was to determine the 5-year incidence of hyperkalemia in a cohort of patients with HFrEF.

[Increase of serum cyclophilin C levels in the follow-up of coronary artery disease: A biomarker and possible clinical predictor].

Objective: This study is aimed at investigating the changes in serum CypC levels and their relationship with cardiovascular events at 12 months of follow-up in coronary artery disease (CAD) patients.

Methods: The study included a total of 125 subjects (40 patients with acute CAD, 40 patients with chronic CAD, and 45 control volunteers) and we analyzed plasma CypC levels from baseline to 6 and 12 months for a better understanding of its behavior in atherosclerosis.

Results: Serum CypC levels were shown to be gradually increased in CAD patients (30.

Differences in the Clinical Profile and Management of Atrial Fibrillation According to Gender. Results of the REgistro GallEgo Intercéntrico de Fibrilación Auricular (REGUEIFA) Trial.

To analyze the clinical profile and therapeutic strategy in atrial fibrillation (AF) according to gender in a contemporaneous patient cohort a prospective, multicenter observational study was performed on consecutive patients diagnosed with AF and assessed by cardiology units in the region of Galicia (Spain). A total of 1007 patients were included, of which 32.3% were women.

Syncope triggered by atrial flutter in a patient with a pacemaker: cross-stimulation-a case report.

Background: Syncope in a patient with a pacemaker is a serious event requiring urgent action to ascertain its cause. Around 5% of cases are due to a pacemaker system malfunction.

Case Summary: An 82-year-old man underwent dual-chamber permanent pacemaker implantation due to intermittent high-degree atrioventricular block (AVB) in sinus rhythm.

Structural and functional inverse cardiac remodeling after cavotricuspid isthmus ablation in patients with typical atrial flutter.

Introduction And Objectives: The purpose of the present study is to determine the structural and functional cardiac changes that occur in patients at 1-year follow-up after ablation of typical atrial flutter.

Methods: We enrolled 95 consecutive patients referred for cavotricuspid isthmus ablation. Echocardiography was performed at ≤6h post-procedure and 1-year follow-up.

GRACE risk score predicts contrast-induced nephropathy in patients with acute coronary syndrome and normal renal function.

We evaluated the incidence, clinical predictors, and outcomes of contrast-induced nephropathy (CIN) after coronary angiography in patients with myocardial infarction and normal kidney function. We studied 202 consecutive patients with glomerular filtration rate >60 mL/min/1.73 m(2).
