Atrial tachycardia and atrial flutter are common tachyarrhythmias in the heart failure population. They commonly lead to, exacerbate, and increase the morbidity and mortality associated with heart failure and, thereby, warrant urgent and early definitive therapy in the form of catheter ablation. Catheter ablation requires careful patient stabilization and extensive preprocedural planning, particularly with regards to anesthesia, strategy, catheter choice, mapping system, and fluid balance, to increase efficacy and limit adverse effects. Heart failure may limit the success of catheter ablation with higher reported recurrence rates, and in selected patients, a hybrid epicardial-endocardial ablation can be considered.

Cardiomeds, an mHealth App for Self-Management to Support Swiss Patients With Heart Failure: 2-Stage Mixed Methods Usability Study.
JMIR Form Res

Department of Computer Science, University Hospital of Geneva, Geneva, Switzerland.
Background: Mobile health apps have shown promising results in improving self-management of several chronic diseases in patients. We have developed a mobile health app (Cardiomeds) dedicated to patients with heart failure (HF). This app includes an interactive medication list; daily self-monitoring of symptoms, weight, blood pressure, and heart rate; and educational information on HF delivered through various formats.

Little is known about the effects of sodium-glucose co-transporter 2 inhibitors (SGLT2i) on atherosclerosis. We aimed to determine if a 90-day intake of Dapagliflozin could improve atherosclerosis biomarkers (namely endothelial function assessed by flow-mediated dilatation [FMD] and carotid intima-media thickness [CIMT]) in diabetic and non-diabetic acute coronary syndrome (ACS) patients when initiated in the early in-hospital phase. ATH-SGLT2i was a prospective, single-center, observational trial that included 113 SGLT2i naive patients who were admitted for ACS and who were prescribed Dapagliflozin at a fixed dose of 10 mg during their hospital stay for either type 2 diabetes or for heart failure.

Introduction: Data on the prevalence of hypertrophic cardiomyopathy (HCM), characteristics of patients with HCM, and treatment patterns in Japan are limited. This study aimed to estimate the prevalence of HCM and describe the patient characteristics, treatment patterns, and utilization of medical expense subsidies in Japan, using payer claims data from insurers.
Methods: This retrospective study of patients with HCM in Japan utilized payer claims data from insurers (Advanced Elderly Medical Service System [AEMSS], Kokuho, and Kempo) from January 1, 2017, to December 31, 2021.
Time course of hospitalizations in patients with heart failure and chronic obstructive pulmonary disease around sleep-disordered-breathing diagnosis.
Sleep Breath

Department of Internal Medicine II (Cardiology, Pneumology, and Intensive Care), University Medical Centre Regensburg, Regensburg, Germany.
Purpose: In heart failure (HF) and chronic obstructive pulmonary disease (COPD) populations, sleep-disordered breathing (SDB) is associated with impaired health outcomes. We evaluated whether in patients with HF, concomitant HF and COPD or COPD, the number of hospitalizations would be reduced in the year after testing for SDB with and without treatment initiation compared to the year before.
Methods: We performed a multicentre retrospective study of 390 consecutive sleep-clinic patients who had a primary diagnosis of chronic HF, HF and COPD or COPD and a secondary diagnosis of SDB.
Reduced antioxidant high-density lipoprotein function in heart failure with preserved ejection fraction.

Background: Heart failure (HF) is a heterogeneous clinical syndrome affecting a growing global population. Due to the high incidence of cardiovascular risk factors, a large proportion of the Western population is at risk for heart failure. Oxidative stress and inflammation play a crucial role in the pathophysiology of heart failure with preserved ejection fraction (HFpEF).
