KLF2-dependent transcriptional regulation safeguards the heart against pathological hypertrophy.

Background: Our previous single-cell RNA sequencing study in the adult human heart revealed that cardiomyocytes from both the atrium and ventricle display high activities of Krüppel-like factor 2 (KLF2) regulons. However, the role of the transcription factor KLF2 in cardiomyocyte biology remains largely unexplored.

Methods And Results: We employed transverse aortic constriction surgery in male C57BL/6 J mice to develop an in vivo model of cardiac hypertrophy, and generated different in vitro cardiac hypertrophy models in neonatal rat ventricular myocytes and human embryonic stem cell-derived cardiomyocytes.

Downregulation of MLF1 safeguards cardiomyocytes against senescence-associated chromatin opening.

Aging-associated cardiac hypertrophy (AACH) increases susceptibility to heart failure in the elderly. Chromatin remodeling contributes to the gene reprogramming in AACH; however, the intrinsic regulations remain elusive. We performed a transcriptome analysis for AACH in comparison with pressure-overload-induced pathological cardiac hypertrophy in mice and identified myeloid leukemia factor 1 (MLF1) as an aging-sensitive factor whose expression was reduced during aging but could be reversed by anti-aging administrations.

Forecasting cardiovascular disease risk and burden in China from 2020 to 2030: a simulation study based on a nationwide cohort.

Background: Cardiovascular disease (CVD) remains a significant public health challenge in China. This study aimed to project the burden of CVD from 2020 to 2030 using a nationwide cohort and to simulate the potential impact of various control measures on morbidity and mortality.

Methods: An agent-based model was employed to simulate annual CVD incidence and mortality from 2021 to 2030.

Turnover intention among healthcare workers in Shenzhen, China: the mediating effect of job satisfaction and work engagement.

Background: To ensure workforce stability in China's healthcare system and maintain high-quality care, it is essential to comprehensively understand the interplay of factors contributing to turnover intention of healthcare workers. This study aims to examine the associations between potential factors and turnover intention in healthcare workers and explore the mediating effect of job satisfaction and work engagement in the association between them.

Methods: In this cross-sectional study, a random sample of 1060 healthcare workers working in 98 public medical institutions were recruited to rate their turnover intention in 2018 in Shenzhen, China.

The impact of right atrial volume on ablation outcomes in patients with pulmonary hypertension and atrial flutter.

Background: Catheter ablation has evolved as a safe treatment for atrial flutter (AFL) in patients with pulmonary hypertension (PH), and the recurrence of AFL may accelerate clinical decompensation. The aim of this study was to determine the recurrence rate and risk factors for recurrent AFL in PH patients after ablation.

Methods: All PH patients who underwent AFL ablation at Fuwai Hospital between May 2015 and December 2020 were followed up.

Empirical superior vena cava electrical isolation guided by quantitative ablation index improves outcomes of radiofrequency catheter ablation for paroxysmal atrial fibrillation.

Background: The value of empirical superior vena cava isolation (SVCI) following pulmonary vein isolation (PVI) to improve the efficacy of radiofrequency catheter ablation (RFCA) for paroxysmal atrial fibrillation (PAF) remains controversial.

Objective: To evaluate the efficacy and safety of quantitative ablation index (AI)-guided empirical SVCI, in addition to PVI, for patients with PAF.

Methods: Patients with symptomatic PAF who underwent RFCA between October 2021 and May 2023 were retrospectively analysed.

Usefulness of estimated glucose disposal rate in detecting heart failure: results from national health and nutrition examination survey 1999-2018.

Background: Estimated glucose disposal rate (eGDR) is a novel, clinically available, and cost-effective surrogate of insulin resistance. The current study aimed to assess the association between eGDR and prevalent heart failure (HF), and further evaluate the value of eGDR in detecting prevalent HF in a general population.

Methods: 25,450 subjects from the National Health and Nutrition Examination Survey 1999-2018 were included.

Learning implementation of a guideline based decision support system to improve hypertension treatment in primary care in China: pragmatic cluster randomised controlled trial.

Objective: To evaluate the effectiveness of a clinical decision support system (CDSS) in improving the use of guideline accordant antihypertensive treatment in primary care settings in China.

Design: Pragmatic, open label, cluster randomised trial.

Setting: 94 primary care practices in four urban regions of China between August 2019 and July 2022: Luoyang (central China), Jining (east China), and Shenzhen (south China, including two regions).

Direct oral anticoagulants in the treatment of chronic thromboembolic pulmonary hypertension patients: A retrospective cohort study.

Introduction: Direct oral anticoagulants (DOACs) are increasingly prescribed for life-long anticoagulation in chronic thromboembolic pulmonary hypertension (CTEPH) patients, despite not being recommended in the guidelines. This study aims to evaluate the efficacy and safety of DOACs in CTEPH patients.

Methods: From May 2013 to December 2022, patients who were first diagnosed with CTEPH in Fuwai Hospital and started long-term anticoagulation treatment with warfarin or DOACs were retrospectively included and followed up until (1) death, (2) transition to other kinds of anticoagulants, or (3) discontinuation of anticoagulation.
