摘要: 背景 托伐普坦在老年慢性心力衰竭(CHF)患者中应用广泛,但不同剂量的托伐普坦对老年CHF患者预后的影响尚不明确。 目的 探讨7.5 mg/d和15.0 mg/d两种常用剂量的托伐普坦对高龄老年CHF患者预后的影响。 方法 回顾性分析2016年2月至2022年2月于中国人民解放军联勤保障部队第九六〇医院保健病房采用托伐普坦药物治疗CHF的高龄(年龄≥80岁)老年患者的临床资料,按照托伐普坦应用剂量分为7.5 mg/d组和15.0 mg/d组。以全因死亡、心血管死亡出现或至随访结束为随访终点。绘制Kaplan-Meier生存曲线,分析两组患者全因死亡与心血管死亡的差异。采用Cox比例风险回归模型分析两种剂量托伐普坦对老年CHF患者全因死亡和心血管死亡的影响。 结果 共纳入高龄老年CHF患者212例,随访374.5(155.5,940.5)d,随访期间共124例(58.5%)患者发生全因死亡,54例(25.5%)患者发生心血管死亡。Kaplan-Meier生存曲线比较显示,托伐普坦15.0 mg/d组全因死亡率和心血管死亡率均高于托伐普坦7.5 mg/d组(P=0.004 3,P=0.001 2)。多因素Cox比例风险回归模型分析显示,在校正了年龄、纽约心脏协会(NYHA)心功能分级、慢性肾脏病(CKD)、糖尿病、高血压、冠心病、利尿剂、白蛋白(ALB)、血清N末端脑钠肽前体(NT-proBNP)与估算肾小球滤过率(eGFR)后,与7.5 mg/d组相比,15.0 mg/d组患者全因死亡和心血管死亡风险分别增加1.03倍〔HR=2.03,95%CI(1.34,2.99)〕和1.51倍〔HR=2.51,95%CI(1.40,4.50)〕。对eGFR、年龄、ALB、NT-proBNP进行分层分析结果显示,托伐普坦15.0 mg/d组全因死亡和心血管死亡的风险仍增加。 结论 在高龄(年龄≥80岁)老年CHF患者中,托伐普坦15.0 mg/d组比托伐普坦7.5 mg/d组全因死亡和心血管死亡风险增加,推荐使用7.5 mg/d托伐普坦。

Abstract:

Background

Tolvaptan is widely used in elderly patients with chronic heart failure (CHF) , but the effect of different doses of tolvaptan on the prognosis of elderly CHF patients is unclear.

Objective

To investigate the effect of two commonly used doses of tolvaptan, 7.5 mg/d and 15.0 mg/d, on the prognosis of elderly patients with CHF.

Methods

This is a retrospective cohort study. This study selected patients (age≥80 years) with CHF treated with tolvaptan in the health care ward of the 960th Hospital of PLA Joint Logistics Support Force of China from February 2016 to February 2022, and analyzed their clinical data. The patients were divided into 7.5 mg/d and 15.0 mg/d groups based on the dose of tolvaptan. The end point of follow-up was the occurrence of all-cause mortality or cardiovascular mortality or until the end of follow-up. This study used Kaplan-Meier method to perform survival curves analysis and used Cox proportional hazards regression models to analyze the effect of two doses of tolvaptan on all-cause mortality and cardiovascular mortality in elderly patients with CHF.

Results

This study enrolled 212 elderly patients with CHF, and the follow-up was 374.5 (155.5, 940.5) days. 124 (58.5%) patients died from all-cause mortality and 54 (25.5%) patients died from cardiovascular mortality during the follow-up. Kaplan-Meier survival curve showed that 15.0 mg/d group had higher rates of all-cause mortality and cardiovascular mortality compared with 7.5 mg/d group (P=0.004 3, P=0.001 2) . Multivariate Cox proportional hazards regression model analysis showed that after adjusting for age, NYHA cardiac functional class, chronic kidney disease, diabetes, hypertension, coronary artery disease, diuretics, albumin (ALB) , serum N-terminal brain natriuretic peptide precursor (NT-proBNP) and estimated glomerular filtration rate (eGFR) , 15.0 mg/d group had a 1.03-fold increased risk of all-cause mortality〔HR=2.03, 95%CI (1.34, 2.99) 〕and 1.51-fold increased risk of cardiovascular mortality〔HR=2.51, 95%CI (1.40, 4.50) 〕compared with 7.5 mg/d group. This study stratified analysis by eGFR, age, ALB, and NT-proBNP, the results showed that tolvaptan 15.0 mg/d group had higher rates of all-cause mortality and cardiovascular mortality.

Conclusion

Tolvaptan 15.0 mg/d group had higher rates of all-cause mortality and cardiovascular mortality compared with tolvaptan 7.5 mg/d in elderly CHF patients (age≥80 years) . We may recommend using low-dose tolvaptan.
