目的:探讨肌钙蛋白Ⅰ在扩张性心肌病患者中与心衰的关系。方法:在确诊的扩张型心肌病患者中,测定按纽约心脏协会(NYHA)在不同心功能分级时血清肌钙蛋白Ⅰ(cTn-Ⅰ)水平,分析肌钙蛋白Ⅰ(cTn-Ⅰ)与心衰的关系。结果:肌钙蛋白Ⅰ(cTn-Ⅰ)水平在不同心功能组有明显差异,分级越高,肌钙蛋白Ⅰ(cTn-Ⅰ)水平越高。结论:扩张型心肌病患者cTn-Ⅰ水平随心衰程度加重而增高,是心功能下降的反应指标。
Objective: To investigate the relationship between troponin I and heart failure in patients with dilated cardiomyopathy. Methods: The levels of serum cardiac troponin Ⅰ (cTn-Ⅰ) were measured in patients with New York Heart Association (NYHA) at different cardiac function levels in patients diagnosed with dilated cardiomyopathy. The levels of cardiac troponin Ⅰ (cTn-Ⅰ) Bad relationship. Results: The level of cTn-Ⅰ was significantly different in different cardiac function groups. The higher the level of cTn-Ⅰ, the higher the level of cTn-Ⅰ. Conclusion: The level of cTn-Ⅰ in patients with dilated cardiomyopathy increases with the severity of heart failure, which is a response indicator of decreased cardiac function.
