Association between statin use and the risk of atrial fibrillation in community-dwelling older people in Shanghai, China: a propensity score-matched study

For older people, taking statins did not reduce risk of new on-set AF. Independent predictors of AF onset including age, SBP, BMI, HbA1c and Scr. This is a retrospective cohort study, making it difficult to completely control for all confounding factors, and the short follow-up period may have resulted in insufficient statistical power to detect a meaningful effect of statins on atrial fibrillation. Future studies may use randomized controlled studies to explore the effects of different types and doses of statins on new-onset atrial fibrillation in older adults.
