SAFER-AF is an investigator-initiated, multicenter, open-label, parallel-group trial comparing catheter ablation versus usual care in patients with atrial fibrillation and intracranial hemorrhage.

Structural heart disease-related ventricular tachycardia (SHD-VT) is associated with substantial morbidity and mortality. Although catheter ablation, ICD therapy, antiarrhythmic drugs, and other treatment strategies are widely used, real-world evidence regarding patient characteristics, management patterns, long-term outcomes, and prognostic factors in China remains limited. This nationwide, multicenter, prospective observational registry aims to establish a comprehensive longitudinal database of patients with SHD-VT. Approximately 1,000 consecutive adult patients with documented sustained ventricular tachycardia, or clinically significant nonsustained ventricular tachycardia requiring treatment, in the presence of structural heart disease will be enrolled and followed prospectively. The study will collect detailed demographic characteristics, medical history, imaging findings, laboratory data, electrophysiological characteristics, treatment strategies, and follow-up outcomes without influencing routine clinical management. The primary effectiveness outcome is a composite of ventricular tachycardia recurrence or appropriate ICD therapy (when applicable), unplanned cardiovascular hospitalization, or all-cause death within 12 months. Long-term follow-up will continue to evaluate clinical outcomes, treatment safety, and prognostic factors. The registry is expected to provide high-quality real-world evidence to improve risk stratification, optimize clinical decision-making, and support future clinical research in patients with SHD-VT.

This prospective observational study aims to investigate the association between risk factors and cognitive function in patients with coronary heart disease (CHD), and to explore the underlying mechanisms involving metabolic parameters and multimodal imaging features. A total of 2,352 participants will be enrolled from Beijing Anzhen Hospital, Capital Medical University, China. Eligible participants are adults (≥18 years) with confirmed CHD who undergo systematic neuropsychological assessment during hospitalization. Comprehensive assessments include cognitive function tests (MMSE, MoCA, BCAT, AD8), metabolic evaluations (fasting glucose, insulin, HbA1c, ceramides), coronary computed tomography angiography (CCTA), cardiac magnetic resonance (CMR), sleep respiratory monitoring, and frailty and psychological assessments.The primary outcome is cognitive impairment. The study will identify potential risk factors and provide insights into early identification and personalized intervention strategies for cognitive decline in CHD patients.This study is led by the National Clinical Research Center for Cardiovascular Diseases and invited to be carried out by several Chinese centers including Beijing Anzhen Hospital.

With the advancement of wearable technology, continuous non-invasive monitoring of vital signs, arrhythmia burden, and physical status has become increasingly feasible. Devices such as smartwatches and electrocardiogram (ECG) straps can provide real-time physiological data, offering new opportunities for remote and proactive disease management. Despite the growing availability of such real-time data, the complex interaction between atrial fibrillation (AF) and heart failure (HF) necessitates highly personalized management. However, there remains a lack of high-quality clinical evidence on how to effectively integrate wearable device data into these personalized strategies for specific patient populations. Moreover, the prognostic impact of wearable device-assisted remote management has not been comprehensively evaluated. Therefore, robust clinical studies are needed to further evaluate whether wearable device-assisted remote monitoring can improve the long-term prognosis of this population after discharge from the cardiac care unit (CCU). In this study (WARM-HF Stage 2), the investigators will conduct a prospective, multicenter, randomized controlled trial to determine whether wearable devices can reduce the composite endpoint of readmission or death in patients with HF.

This multicenter, randomized, controlled trial evaluates a combined embolic protection strategy during carotid artery stenting (CAS). Carotid artery stenosis is a major cause of stroke. While stenting is an effective treatment, the procedure itself carries a risk of dislodging plaque debris, which can travel to the brain and cause new strokes or silent brain infarctions. Currently, a distal filter (protection device) is standardly used to catch debris. However, it may not capture all particles. This study investigates whether adding a Balloon Guide Catheter (BGC)-which temporarily stops blood flow and allows for aspiration-to the standard filter protection is more effective than using the filter alone. Patients with symptomatic (≥50% stenosis) or asymptomatic (≥70% stenosis) carotid artery stenosis who are scheduled for stenting will be randomly assigned to one of two groups: 1. Combined Protection Group: Receiving CAS using a Balloon Guide Catheter combined with a distal filter. 2. Standard Protection Group: Receiving CAS using a distal filter alone. The primary goal is to determine if the combined approach reduces the number of new ischemic lesions detected on brain MRI within 72 hours post-procedure. The study will also assess clinical stroke events over a 90-day follow-up period.

The WISER-AF trial is a multicenter, double-blind, sham-controlled, randomized controlled trial. It aims to evaluate the efficacy and safety of catheter ablation compared to a sham procedure in improving the quality of life (SF-36 score) in very elderly patients (aged ≥80 years) with symptomatic atrial fibrillation over a 6-month follow-up period.

The study is a multicenter, two-arm, open-label, randomized, parallel-controlled trial, which plans to enroll 236 participants diagnosed with TAAA from 4 hospitals in China. All patients receive TAAAR procedure and are randomized to control group (LHB) and experimental group (fCPB) in the ratio of 1:1. After a 1-year follow-up, the validity and safety of the different cardiopulmonary bypass for TAAAR is evaluated via the incidence of major adverse events including surgical mortality, RRT, stroke, and SCI, as well as intraoperative blood product transfusion volume, mechanical ventilation, and early mortality.

Patients with acute decompensated heart failure (HF) have a significantly high risk of death and HF re-hospitalization during the vulnerable phase post discharge. Therefore, early post-discharge management is crucial, and the cornerstone of HF treatment-particularly for HF with reduced ejection fraction (HFrEF)-is guideline-directed medical therapy (GDMT), a comprehensive pharmacotherapeutic strategy supported by robust clinical evidence. Timely titration of GDMT, especially within the first few weeks after discharge, has been shown to improve clinical outcomes, reduce readmissions, and enhance long-term prognosis. However, ensuring optimal follow-up and therapeutic adjustments remains a major challenge in real-world practice. Atrial fibrillation (AF) is a common comorbidity in patients with HF, especially in those with severe HF. The presence of AF significantly complicates the clinical course and worsens the prognosis of HF. Advances in wearable technology have made continuous, non-invasive monitoring of vital signs, arrhythmia burden, and physical status increasingly feasible. Devices such as smartwatches and ECG belts can provide real-time physiological data, offering new opportunities for remote and proactive disease management. Despite the growing availability of such data, the complex interplay between AF and HF demands highly personalized management. Currently, there is a lack of high-quality clinical evidence on how to effectively integrate wearable device data into personalized strategies for this specific patient population. This is an open-label, multi-center, endpoint-blinded, parallel-group randomized clinical trial supported by the American Heart Association. The primary objective is to determine whether wearable device-assisted digital consultations can optimize GDMT in patients with AF complicated by acute decompensated HF. The study plans to enroll 400 participants, who will be randomly assigned to either a wearable device-assisted intervention group or a conventional treatment control group. The primary endpoint is the change in HF GDMT score 3 months after randomization. Apple Inc. provided funding, devices, and technical support for this study. Apple was not a sponsor of the trial and was not involved in its execution, data analysis, interpretation, or manuscript preparation.

Atrial fibrillation (AF) is one of the most common clinical arrhythmias. Catheter ablation is an effective therapeutic strategy; however, recurrence rates remain substantial, ranging from 20% to 45%. Previous studies have established a strong association between obstructive sleep apnea (OSA) and the risk of AF recurrence following ablation. While continuous positive airway pressure (CPAP) is the standard intervention for OSA, and some observational studies suggest it may reduce post-ablation recurrence in patients with comorbid OSA, small randomized controlled trials have failed to confirm a clear benefit, potentially due to poor adherence. This study aims to evaluate the clinical benefit of post-ablation CPAP therapy in AF patients with comorbid OSA. Participants will: * Be randomly assigned to either the CPAP group or the usual care group. * If in the CPAP group, use a CPAP device for 12 months. * Wear an ambulatory ECG recorder for a 7-day period at 3, 6, 9, and 12 months post-operation. * Complete follow-up checkups either at the clinic or over the phone at 1, 3, 6, and 12 months after their procedure.

This prospective cohort study aims to investigate postoperative cognitive dysfunction in patients undergoing off-pump coronary artery bypass grafting. Eligible patients will be enrolled before surgery and followed after surgery. Cognitive function will be assessed using the Montreal Cognitive Assessment before surgery and at predefined postoperative time points. Perioperative clinical information, including preoperative assessment data, intraoperative monitoring parameters, and postoperative clinical data, will be collected. The study will evaluate the occurrence of postoperative cognitive dysfunction and explore its association with perioperative factors.

This study is designed to evaluate the safety and preliminary efficacy of all-trans retinoic acid (ATRA) as an initial treatment for patients with active hemophagocytic lymphohistiocytosis (HLH). HLH is a severe hyperinflammatory syndrome caused by excessive activation of immune cells and uncontrolled cytokine release. Current treatment often requires intensive immunosuppressive or cytotoxic therapy, which may be associated with significant toxicity. ATRA is an orally available agent that has been widely used in other hematologic diseases and has immunomodulatory effects. Preclinical studies suggest that ATRA may help control HLH-related inflammation and improve immune dysregulation. In this study, patients with newly diagnosed or treatment-naïve active HLH will receive ATRA-based initial therapy. The study will assess clinical response, changes in HLH-related inflammatory markers, organ function, viral or disease-related parameters when applicable, and treatment-related adverse events. The goal of this study is to determine whether ATRA can provide a safe and feasible initial therapeutic approach for active HLH and support further clinical development of ATRA-based treatment strategies in this disease.

This is a prospective, non-randomized, multicenter observational registry study designed to systematically evaluate the long-term efficacy and safety of catheter ablation for treating atrial fibrillation (AF) and ventricular tachycardia (VT) in Chinese patients.

Heart failure (HF) refers to impaired cardiac function caused by various heart diseases. Patients commonly present with dyspnea, fatigue, edema and other symptoms, ranking among the leading causes of death from cardiovascular diseases worldwide. According to World Health Organization statistics, more than 26 million people globally suffer from heart failure. The rising prevalence of aging population, hypertension, diabetes and other comorbidities continues to expand the patient population, imposing a heavy burden on families and society. Body mass index (BMI) was traditionally adopted to assess the correlation between obesity and heart failure, yet this method has inherent limitations. The obesity paradox indicates that obese heart failure patients may achieve better recovery outcomes than those with normal weight. Additionally, BMI fails to differentiate the impacts of adipose tissues distributed in distinct anatomical sites. Advances in imaging technology have enabled accurate quantification of regional fat deposits, including epicardial adipose tissue (EAT), subcutaneous adipose tissue (SAT) and intramuscular adipose tissue (IMAT). Domestic and international studies have verified that fat distribution exerts greater influence than total fat volume. Directly adjacent to the myocardium, EAT may secrete inflammatory mediators and induce myocardial injury. SAT produces protective bioactive substances, while its effects vary across heart failure subtypes and remain inconclusive. IMAT is correlated with reduced physical activity and poor clinical prognosis. Nevertheless, most existing researches focus solely on single-site fat tissue or specific heart failure types. Comprehensive combined analysis of cardiac, somatic and muscular adipose tissues, as well as systematic comparison among diverse heart failure subtypes, remains insufficient. This study intends to quantify the three types of adipose tissues simultaneously, combined with cardiac structural and functional examinations, to explore their associations with heart failure. The findings are expected to facilitate precise risk stratification and individualized therapeutic strategy formulation for clinicians.

POTENTIAL-AF is a prospective, multicentre, observational registry study evaluating the real-world effectiveness and safety of bi-polar pulse-field tip-catheter ablation (PFA) for atrial fibrillation (AF) in China. The study will enrol 30,000 adult patients with symptomatic paroxysmal or persistent AF who have failed at least one antiarrhythmic drug (Class I or III) and are planned to undergo PFA using the Jinjiang LEAD-PFA system with PulsedFA catheter at participating centres across China. All procedural decisions, including energy settings, ablation targets, and peri-procedural management, are made by the treating physician per routine clinical practice. The study prospectively collects baseline clinical characteristics, intraoperative ablation parameters, and follow-up outcomes at 3 months, 6 months, 12 months, and every 6 months thereafter, for up to 10 years. The primary endpoint is all-cause mortality at 10 years. Secondary endpoints (observed over 5 years) include ischaemic stroke, haemorrhagic stroke, transient ischaemic attack (TIA), cardiovascular death, cardiovascular hospitalisation, systemic embolism, thromboembolic death, major bleeding, and clinically relevant non-major bleeding (CRNMB). By capturing large-scale, standardised, long-term data across diverse Chinese centres, POTENTIAL-AF aims to describe real-world procedural practice patterns, identify predictors of clinical outcomes, and provide evidence to support the safe and effective application of the Jinjiang bi-polar tip PFA catheter in Chinese AF patients.
