Tóm tắt

OBJECTIVE: To investigate the relationship between cardiopulmonary exercise test (CPET) parameters and the occurrence of atrial fibrillation (AF) in patients with hypertrophic cardiomyopathy (HCM). METHODS: A retrospective study was conducted on 160 HCM patients hospitalized at Quanzhou First Hospital Affiliated to Fujian Medical University from June 2020 to December 2023. Patients were divided into AF (n=62) and non-AF (n=98) groups. Univariate analysis and logistic regression were used to compare demographic and CPET parameters between groups. A nomogram model was developed to predict AF risk. RESULTS: AF prevalence was 38.75%. Peak Oxygen Uptake per kilogram (Peak VO CONCLUSION: CPET parameters, combined with clinical indicators, can effectively predict AF risk in HCM patients. The nomogram model provides a valuable tool for clinical risk assessment.
