Heart failure is a prevalent and life-threatening syndrome characterized by structural and/or functional abnormalities of the heart. As a global burden with high rates of morbidity and mortality, there is growing recognition of the beneficial effects of exercise on physical fitness and cardiovascular health. A substantial body of evidence supports the notion that exercise can play a protective role in the development and progression of heart failure and improve cardiac function through various mechanisms, such as attenuating cardiac fibrosis, reducing inflammation, and regulating mitochondrial metabolism. Further investigation into the role and underlying mechanisms of exercise in heart failure may uncover novel therapeutic targets for the prevention and treatment of heart failure.

Background: Non-response to cardiac resynchronization therapy (CRT) is an important issue in the treatment of heart failure with reduced ejection fraction (HFrEF) and non-left bundle branch block (LBBB). Electrocardiogram-gated myocardial perfusion single-photon emission computed tomography imaging (G-MPI SPECT) is typically used to assess left ventricular (LV) dyssynchrony. This study aimed to determine whether G-MPI parameters are associated with non-responsiveness to CRT.

Left bundle branch pacing (LBBP) is an emerging physiological pacing technique characterized by stable pacing parameters and a narrower QRS duration. This study aims to compare the long-term efficacy and safety of biventricular pacing (BIVP) and LBBP in patients with heart failure with reduced ejection fraction (HFrEF) and complete left bundle branch block (CLBBB). A retrospective analysis was conducted on 35 patients with chronic HFrEF accompanied by CLBBB treated at our center from April 2018 to October 2022.

Angina pectoris (AP), a clinical syndrome characterized by paroxysmal chest pain, is caused by insufficient blood supply to the coronary arteries and sudden temporary myocardial ischemia and hypoxia. Long-term AP typically induces other cardiovascular events, including myocardial infarction and heart failure, posing a serious threat to patient safety. However, AP's complex pathological mechanisms and developmental processes introduce significant challenges in the rapid diagnosis and accurate treatment of its different subtypes, including stable angina pectoris (SAP), unstable angina pectoris (UAP), and variant angina pectoris (VAP).

Background: Sodium glucose transporter 2 inhibitor (SGLT2i) is the latest guideline-directed medical therapy for patients with heart failure, as it has demonstrated favorable cardiovascular outcomes in heart failure (HF) patients with or without diabetes. Furthermore, SGLT2i has effectively improved cognitive function in older adults with diabetes and HF. However, the effects of SGLT2i on cognitive function and brain mitochondrial function in rats with ischemic HF have never been investigated.

Background: Cognitive dysfunction occurs in approximately 40% of individuals diagnosed with heart failure (HF). This study aims to describe perceived cognitive effectiveness among patients with HF and examine associations with performance-based measures of cognitive dysfunction.
Method: Baseline data were used from a 2-group randomized controlled trial testing a cognitive intervention to improve attention among 73 patients with HF.
