| Summary: | OBJECTIVE:To assess the relationship between coronary heart disease (CHD) and menopausal symptoms in middle-aged women in Taiwan. PATIENTS AND METHODS:The present study identified 14,340 symptomatic menopausal women without a history of CHD from the Taiwan National Health Insurance Research Database from January 1, 2000, to December 31, 2013. A total of 14,340 age- and Charlson-comorbidity-index-score-matched asymptomatic women were used as controls. Possible comorbidity-attributable risks of CHD were surveyed to assess whether the symptomatic menopausal cohort had a higher incidence of CHD. RESULTS:The incidence of CHD was higher in the symptomatic menopausal cohort than in the control cohort (17.18 vs. 12.05 per 1000 person-years). After adjustment in multivariate Cox analysis, the risk of CHD was significantly higher in the symptomatic menopausal cohort (adjusted hazard ratio = 1.344, 95% confidence interval [CI] = 1.262-1.43, P < 0.001) than in the control cohort. In the symptomatic menopausal cohort, the risk of CHD was significantly higher in all subgroups, except for the hormone therapy (HT) subgroup. Patients undergoing HT had a nonsignificantly higher risk of CHD, regardless of the presence or absence of menopausal symptoms. CONCLUSION:This large-scale longitudinal retrospective cohort study revealed that menopausal symptoms are an independent risk factor for CHD. Moreover, our findings indicate that HT has a nonsignificant effect on the risk of CHD.
