BackgroundMany patients with obesity in Taiwan seek Chinese herbal medicines (CHM) from traditional Chinese medicine (TCM) clinics. This study aimed to estimate the risk of major adverse cardiovascular events (MACEs) in adults diagnosed with obesity, with or without CHM.MethodsPatients with obesity aged 18 to 50 years were identified using diagnostic codes from Taiwan's National Health Insurance Research Database between 2008 and 2018. We randomized 67,655 patients with or without CHM using propensity score matching. All patients were followed up from the start of the study until MACEs, death, or the end of 2018. A Cox proportional regression model was used to evaluate the hazard ratios of MACEs in the CHM and non-CHM cohorts.ResultsDuring a median follow-up of 4.2 years, the CHM group had a higher incidence of MACEs than the non-CHM control cohort (9.35 versus 8.27 per 1,000 person-years). The CHM group had a 1.13-fold higher risk of MACEs compared with the non-CHM control (adjusted hazard ratio [aHR] = 1.13; 95% confidence interval [CI]: 1.07-1.19; p <0.001), especially in ischemic stroke (aHR = 1.18; 95% CI: 1.07-1.31; p <0.01), arrhythmia (aHR = 1.26; 95% CI: 1.14-1.38; p <0.001), and young adults aged 18 to 29 years (aHR = 1.22; 95% CI: 1.05-1.43; p <0.001).ConclusionAlthough certain CHMs offer cardiovascular benefits, young and middle-aged obese adults receiving CHM exhibit a higher risk of MACEs than those not receiving CHM. Therefore, TCM practitioners should be cautious when prescribing medications to young patients with obesity, considering their potential cardiovascular risks.Copyright © 2024, the Chinese Medical Association.
