Abstract Aims Heart failure with reduced ejection fraction (HFrEF) significantly impacts health‐related quality of life (HR‐QoL). Existing HR‐QoL questionnaires can show inconsistencies, potentially misrepresenting patient self‐reports. This study examines the variation in HR‐QoL measurement tools for HFrEF patients, identifying related determinants. Methods and results We retrospectively analysed 134 hospitalized patients with acute decompensated HFrEF at a Taiwanese tertiary centre's Heart Failure Post‐Acute‐Care (HF‐PAC) programme. Participants completed the EuroQol‐5 dimension (EQ‐5D) questionnaire, the EQ‐5D visual analogue scale (VAS), and the Minnesota Living with Heart Failure Questionnaire (MLHFQ). Utility values were obtained from the EQ‐5D questionnaire. Demographic features were depicted using descriptive statistics, while multivariate regression was used to ascertain relationships between HR‐QoL measurements and determinants. Average scores for EQ‐5D, MLHFQ, EQ‐5D utility, and VAS were 6.1 ± 1.6, 21.8 ± 21.3, 81.7 ± 27.0, and 59.5 ± 14.6, respectively. Significant correlations were observed among the three tools. The New York Heart Association functional class showed a notable association with all tool scores. Other associations encompassed EQ‐5D with coronary artery disease, mineralocorticoid receptor antagonists, and the 6 min walk test; EQ‐5D VAS with chronic kidney disease; and MLHFQ with age. Conclusions This study illuminates the variance in HR‐QoL measurement tools for Taiwanese HFrEF patients. Using a range of these tools is beneficial in unveiling diverse determinants and approaching comprehensive patient‐centred care. However, for a more precise HR‐QoL assessment in Taiwanese HFrEF patients, recalibrating the EQ‐5D‐derived utility scores might be necessary, emphasizing the importance of patient‐specific considerations within the HF‐PAC programme.

Abstract Background Ivabradine, a medical treatment for heart failure (HF), reduces heart rate (HR) and prolongs diastolic perfusion time. It is frequently prescribed to patients with HF who have a suboptimal response or intolerance to beta‐blockers. Degenerative mitral regurgitation (MR) is a valvular heart disease often associated with the development of HF and atrial fibrillation (AF). However, studies comparing the effects of ivabradine and beta‐blockers on MR are lacking. Therefore, this study aimed to explore the potential therapeutic effects of ivabradine and carvedilol on MR using a rat model. Methods and results Using a novel echo‐guided mini‐invasive surgery, MR was created in 12‐weeks‐old Sprague–Dawley rats. After 2 weeks, the rats were randomized to receive either ivabradine or carvedilol for 4 weeks. Echocardiography was performed at baseline and at two‐week intervals. Following haemodynamic studies, postmortem tissues were analysed. Notably, the MR‐induced myocardial dysfunction did not improve considerably after treatment with ivabradine or carvedilol. However, in haemodynamic studies, pharmacological therapies, particularly carvedilol, mitigated MR‐induced chamber dilatation (end‐systolic volume and end‐diastolic volume; MR vs. MR + Carvedilol; P

This article, titled "Huge Left Atrial Myxoma Obstructs the Mitral Valve and Causes Massive Pleural Effusion," discusses the case of a 57-year-old woman who experienced progressive exertional dyspnea and orthopnea. Physical examination revealed a low-pitched grade IV diastolic murmur and bilateral basal rales. Lab tests showed elevated levels of N-Terminal Pro-B-Type Natriuretic Peptide and high-sensitivity troponin-I. Imaging tests revealed a large mass in the left atrium obstructing the mitral valve and causing bilateral pleural effusion. Surgical resection successfully resolved the pleural effusion, and the patient remained symptom-free during the six-month follow-up. The article highlights the rarity of this clinical presentation and emphasizes the importance of considering differential diagnoses for transudative pleural effusion, including mitral valve obstruction by myxoma.
