Journal: JAMA cardiology PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41160038 Summary: The ARREST-AF Randomized Clinical Trial is an open-label, multicenter, randomized clinical trial with 12-month follow-up designed to determine the impact of risk factor and weight management on atrial fibrillation ablation rhythm outcomes. This study specifically addresses the need for randomized clinical trial evidence to support observational reports of reduced arrhythmia recurrence after atrial fibrillation ablation with aggressive lifestyle modification. By investigating this relationship, the ARREST-AF trial aims to establish whether lifestyle interventions can significantly improve the long-term success of atrial fibrillation ablation. This will provide crucial data for enhancing treatment strategies for patients with atrial fibrillation. Article 2: Cardiovascular disease-specific and all-cause mortality across socioeconomic status and lifestyles among patients with established cardiovascular disease in communities of China: data from a national population-based cohort. Journal: Heart (British Cardiac Society) PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40081938 Summary: This national population-based cohort study, conducted across 31 provinces in mainland China, investigated cardiovascular disease-specific and all-cause mortality among patients with established cardiovascular disease. Researchers included participants aged 35 to 75 years with self-reported diagnoses, collecting detailed information on socioeconomic status and lifestyle. The study aims to provide crucial evidence regarding socioeconomic status-related health inequality in cardiovascular disease patients who require both lifestyle changes and medical care, particularly in developing countries. This research will establish a clearer understanding of health disparities to inform targeted public health interventions. Article 3: Prevalence, spectrum and aetiology of valvular heart disease based on community echocardiographic screening transition from different altitudes in Yunnan, China. Journal: Heart (British Cardiac Society) PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40032496 Summary: This study investigated the prevalence, spectrum, and etiology of valvular heart disease across different altitudes in Yunnan Province, China, utilizing two sequential community-based echocardiography screening programs.
