The acetylcholinesterase inhibitor donepezil hydrochloride improves cognitive function in patients with Alzheimer's disease and vascular dementia. Given acetylcholine's important actions on the heart, we undertook a retrospective cohort investigation to assess whether donepezil usage affects cardiovascular mortality. In patients treated with donepezil, hazard ratios for total and cardiovascular mortality were 0.68 (P = 0.045, 95% confidence interval 0.46-0.99) and 0.54 (P = 0.042, 95% confidence interval 0.30-0.98), respectively. The apparent survival benefit in donepezil-treated patients should not be overinterpreted. Prospective clinical trials are warranted.
盐酸多奈哌齐是一种乙酰胆碱酯酶抑制剂,可改善阿尔茨海默病和血管性痴呆患者的认知功能。鉴于乙酰胆碱对心脏的重要作用,我们进行了一项回顾性队列研究,以评估多奈哌齐的使用是否会影响心血管死亡率。在接受多奈哌齐治疗的患者中,全因死亡率和心血管死亡率的风险比分别为 0.68(P=0.045,95%置信区间 0.46-0.99)和 0.54(P=0.042,95%置信区间 0.30-0.98)。多奈哌齐治疗组患者的明显生存获益不应被过度解读。需要进行前瞻性临床试验。
