China Atrial Fibrillation With Complex Metabolic Disorder Cohort Study (CAME Cohort)
China Atrial Fibrillation With Complex Metabolic Disorders Cohort Study (CAME Cohort)
Source: ClinicalTrials.gov · Last updated 30 Dec 2025
Brief summary (registry, in English)
The number of atrial fibrillation (AF) patients in China is approximately 32.76 million, with a prevalence rate of 2.3%. AF is associated with severe outcomes such as stroke and heart failure. Metabolic disorders (e.g., obesity, diabetes mellitus, dyslipidemia) are closely linked to the onset and prognosis of AF. However, the epidemiological characteristics and disease burden of AF combined with metabolic disorders in China remain unclear. Additionally, the impact of complex multi-dimensional metabolic disorders on AF prognosis requires further investigation, and current clinical guidelines lack targeted management recommendations for this population.
