Summary: In patients with non-ischaemic dilated cardiomyopathy (NICM) and normalised left ventricular ejection fraction (LVEF), an impaired absolute global longitudinal strain (aGLS) at the time of LVEF recovery is common and associated with worse outcomes.

Summary: This study investigated the safety of spironolactone withdrawal in dilated cardiomyopathy patients with improved ejection fraction. Results showed that most patients experienced relapse after spironolactone withdrawal, with continued use of the drug maintaining improvements in cardiac structure parameters.

Summary: The aim of this study was to determine the prognostic impact of coronary artery disease (CAD) on heart failure with reduced ejection fraction (HFrEF) mortality and readmissions. A total of 583 patients with left ventricular ejection fraction <40% were included in the study, among which 266 had CAD and 137 had idiopathic dilated cardiomyopathy (DCM). The study found that one-year mortality and readmissions were similar between patients with CAD and idiopathic DCM, but patients with idiopathic DCM were more likely to receive a heart transplant.

Summary: In a study on peripartum cardiomyopathy (PPCM), it was found that women typically have normal left ventricular ejection fraction and size during gestation before developing PPCM, but there is a trend towards abnormal global longitudinal and circumferential strain. This indicates that strain imaging could potentially serve as a screening method for high-risk PPCM populations.

Summary: HFpEF is a prevalent form of heart failure with various cardiac and non-cardiac manifestations, diagnosis of which relies on multiple measurements. Despite increasing understanding of its pathophysiology, specific treatment for HFpEF patients remains elusive.

Summary: This study aimed to assess the trajectories of left ventricular ejection fraction (LVEF) in non-ischaemic dilated cardiomyopathy (NICM) with improved ejection fraction (impEF) and their correlation with outcomes. The results showed that approximately 40% of impEF patients had recurrent decline in LVEF, which was associated with an increased risk of adverse cardiac outcomes.

Summary: This study aimed to confirm the effect of augmented reality (AR) glasses on echocardiographic interpretation in patients with heart failure (HF). The results showed that the use of AR glasses improved the consistency of left ventricular ejection fraction (LVEF) measurements, especially for less experienced physicians.

Summary: The study found that microRNA profiles can categorize DCM patients based on their EF, enabling the identification of high-risk individuals. A three-microRNA signature combined with clinical variables was identified as a potential novel prognostic biomarker with high clinical value for categorizing idiopathic DCM.

Summary: This study investigates the characteristics and prognosis of heart failure with preserved ejection fraction (HFpEF) in patients with hypertrophic cardiomyopathy (HCM). The results show that HFpEF patients have greater disease severity and higher mortality than non-HF patients, indicating the need for more aggressive treatment in HF management.

Summary: This paper provides an in-depth review of the relationship between HFpEF and NAFLD, proposing three NAFLD-related HFpEF phenotypes and discussing diagnostic challenges and treatment options. The authors suggest that NAFLD-related HFpEF should be recognized as a distinct HFpEF phenotype.

Summary: The study evaluated the acute effect of outflow tract PVC ablation on electrocardiographic repolarisation markers in 180 patients. The results showed a significant decrease in Tp-e and Tp-e/QT values after PVC ablation, suggesting that frequent outflow tract PVCs increase transmural dispersion of repolarisation which can be attenuated by catheter ablation in the acute phase. Further prospective studies are needed to evaluate the long-term effects of PVC ablation on myocardial repolarisation.

Summary: The study evaluated the success rate of transvenous extraction of chronically implanted leads via the femoral approach using a gooseneck snare with radiofrequency ablation catheter. Results showed that using this approach may be an alternative to simple manual traction with a high success rate, especially when the indwelling time of the leads is long.

Summary: This study identified 24-hour PVC burden as the sole predictor for adequate intraprocedural PVC frequency during idiopathic PVC ablation. The 24-hour rhythm recordings before the procedure play a crucial role in successful mapping and ablation of idiopathic PVCs.

Summary: This case report discusses a patient with acute ischemic heart failure who developed bidirectional ventricular tachycardia and electrical storm, typically induced by hypokalemia. The patient was on invasive mechanical ventilator support, and hypokalemia was related to acute respiratory alkalosis, leading to refractory hypokalemia despite intravenous potassium replacement.

Summary: This study aimed to investigate the predictive factors for the effective antiarrhythmic effect of beta-blockers on premature ventricular complexes (PVC). The study found that the positive response to beta-blockers was associated with a positive correlation between hourly heart rate and PVC number, as well as the QRS width of PVC.

Summary: The study aimed to demonstrate clinical characteristics, predictors of procedural success and long term recurrence of atrial tachyarrhythmia patients undergoing catheter ablation. Analyzing a consecutive cohort of 299 patients, age, left atrium diameter, valvular or congenital heart disease surgery were found to be independent predictors for acute procedural success, recurrence and post-procedural atrial fibrillation in these patients.

Summary: The study observed a relationship between scattered radiation during EP procedures and certain factors, with fluoroscopy time and cumulative air kerma being significantly lower in diagnostic EP studies. Predictors of total air kerma in EP studies performed by trainees included body surface area, fluoroscopy time, not using electro-anatomic mapping, unsuccessful ablation, and atrial flutter ablation.
