使用他汀类药物与冠状动脉疾病女性患者出现房颤的风险下降有关:HERS试验
Objective:
To determine the efficacy of statin treatment in atrial fibrillation (AF) prevention in women.
Design:
Cohort study using data obtained in the Heart and Estrogen/Progestin Replacement Study (HERS).
Setting:
Secondary analysis of a multicentre, randomised controlled clinical trial.
Patients:
2673 Postmenopausal women with coronary disease.
Main outcome measures:
AF prevalence at baseline and incident AF over a mean follow-up of 4.1 years.
Results:
88 Women with AF were identified: 29 at baseline and 59 during follow-up. Women with AF were significantly less likely to be taking a statin at study enrolment than those without AF (22% vs 37%, p="0".003). Baseline statin use was associated with a 65% lower odds of having AF at baseline after controlling for age, race, history of myocardial infarction or revascularisation and history of heart failure (odds ratio 0.35, 95% confidence interval (CI) 0.13 to 0.93, p="0".04). The risk of developing AF during the study among those free from AF at baseline, adjusted for the same covariates, was 55% less for those receiving statin treatment (hazard ratio 0.45, 95% CI 0.26 to 0.78, p="0".004).
Conclusions:
Statin treatment is associated with a lower prevalence and incidence of AF after adjustment for potential confounders in postmenopausal women with coronary disease (Fig 2).
