摘要

tafamidis是一种口服转甲状腺素稳定剂,可提高转甲状腺素淀粉样变性心肌病(atr - cm)患者的生存率,但只有有限的实际数据描述了治疗开始后心脏生物标志物的一系列变化。本研究的主要目的是表征他非他汀治疗的atr - cm患者多个心脏生物标志物域的纵向变化,描述这些参数在常规临床实践中如何随时间演变。我们还报告了未经治疗的患者的相同结果,以反映现代现实世界队列中的自然病史。方法对145例atr - cm患者进行基线和1年随访时的临床、生化和心脏影像学参数的连续评估。结果中位年龄为80岁(范围:73 ~ 86岁),80例(55%)患者接受了他法非迪治疗。在基线时,与未治疗组相比,治疗组更年轻,疾病进展更少。在1年随访中,他法马地治疗与n端前b型利钠肽(NTproBNP)水平、肌钙蛋白-t水平和纽约心脏协会功能等级的稳定相关,而未治疗组表现出恶化(所有比较P <; 0.05)。他法非底的治疗状态与国家淀粉样变性中心或梅奥诊所的疾病分期无显著相关性。结论:sntprobnp水平、肌钙蛋白-t水平和纽约心脏协会功能分级在他非他汀治疗atr - cm患者的真实队列中保持稳定超过1年。这些结果可能有助于为临床实践中的治疗监测策略提供信息。

Longitudinal Changes in Multiple Cardiac Biomarkers in Transthyretin Amyloidosis Cardiomyopathy Patients Treated Vs Untreated with Tafamidis

Background

Tafamidis is an oral transthyretin stabilizer that improves survival in transthyretin amyloidosis cardiomyopathy (ATTR-CM), but only limited real-world data describe serial cardiac biomarker changes following treatment initiation. The primary objective of this study was to characterize longitudinal changes across multiple cardiac biomarker domains in tafamidis-treated ATTR-CM patients, to describe how these parameters evolve over time in routine clinical practice. We also report the same outcomes in untreated patients to reflect the natural disease history in a modern real-world cohort.

Methods

Clinical, biochemical, and cardiac imaging parameters were serially assessed at baseline and 1-year follow-up for 145 ATTR-CM patients, both those treated and those untreated with tafamidis.

Results

The median age was 80 years (range: 73-86), and 80 patients (55%) received tafamidis. At baseline, the treated group was younger and exhibited less advanced disease, relative to the untreated group. Treatment with tafamadis was associated with stabilization in N-terminal pro-B-type natriuretic peptide (NTproBNP) level, troponin-T level, and New York Heart Association functional class at 1-year follow-up, whereas the untreated group demonstrated worsening (all comparisons P < 0.05). Tafamidis treatment status was not significantly associated with National Amyloidosis Center or Mayo Clinic disease stage.

Conclusions

NTproBNP level, troponin-T level, and New York Heart Association functional class remain stable over 1 year in a real-world cohort of tafamidis-treated ATTR-CM patients. These results may help inform therapeutic monitoring strategies in clinical practice.
