Tachycardia-Induced Cardiomyopathy Following Prolonged Ritodrine Infusion During Pregnancy: A Case Report.
Cureus

Department of Obstetrics and Gynecology, Sakakibara Heart Institute, Fuchu, JPN.
Preterm birth remains a leading cause of neurodevelopmental disability in offspring, prompting various preventive measures. However, controversies persist surrounding these approaches, particularly regarding beta-mimetic drugs. In Japan, it remains a concerning reality that ritodrine infusion continues to be used for long-term tocolysis in preterm labor, despite the warning issued by the US Food and Drug Administration.

Universidade Federal de São João Del-Rei, Praça Frei Orlando, 170, São João Del Rei, Minas Gerais, Brazil. Electronic address:
The low durability of bioprosthetic heart valves (BHV), between 10-15 years, is associated with the development of leaflets flutter. Despite increasing calcification and structural damage of the BHV, leaflets flutter is an understudied condition. Therefore, the objective of this study is compare the oscillation characteristics of BHV leaflets obtained by the finite element method (FEM) technique and by the fluid-structural interaction (FSI) technique.

Digit Health
January 2025
Department of Internal Medicine, Seoul National University Hospital, Seoul, Republic of Korea.
Objective: Although the evaluation of left ventricular ejection fraction (LVEF) in patients with atrial fibrillation (AF) or atrial flutter (AFL) is crucial for appropriate medical management, the prediction of reduced LVEF (<50%) with AF/AFL electrocardiograms (ECGs) lacks evidence. This study aimed to investigate deep-learning approaches to predict reduced LVEF (<50%) in patients with AF/AFL ECGs and easily obtainable clinical information.
Methods: Patients with 12-lead ECGs of AF/AFL and echocardiography were divided into those with LVEF <50% and ≥50%.
Guideline-directed medical therapy rates in heart failure patients with reduced ejection fraction in a diverse cohort.
ESC Heart Fail
January 2025
Mid-Atlantic Permanente Research Institute, Mid-Atlantic Permanente Medical Group, Washington, DC, USA.
Aims: Guideline-directed medical therapy (GDMT) is recommended for all patients with heart failure with reduced ejection fraction (HFrEF). Despite this, little data exist describing GDMT use in diverse, real-world populations including the use of vasodilators, prescribed primarily to Black populations. We sought, among a diverse population of HFrEF patients, to determine (1) GDMT use rates and target dosing by medication class and (2) predictors of GDMT use and target dosing by medication class.

JACC Adv
January 2025
Department of Cardiology, Houston Methodist DeBakey Heart & Vascular Center, Houston, Texas, USA.
Background: Limited data exist on the long-term impact of beta-blocker therapy after percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (CAD) and preserved left ventricular ejection fraction (LVEF).
Objectives: The aim of the study was to evaluate the effects of early beta-blocker initiation vs no initiation following PCI in patients with stable CAD and preserved LVEF.
Methods: This retrospective cohort study employed target trial emulation and incident user design, utilizing the TriNetx database (2009-2024).
