Clinical Significance of Joint Detection of BNP, cTnI and T_3 for Senile Heart Failure

Objective To investigate the B-type natriuretic peptide(BNP), serum cardiac troponin(cTnI) and triiodothyronine(T3) combined detection of heart failure in the elderly(HF), and evaluate the clinical value of diagnosing severity etc. Methods 92 patients diagnosed as HF patients and 61 control group blood BNP, cTnI, T3 level. Evaluated the sensitivity and specificity of each index, and analyzed the diagnostic value of combined detection of 3 indicators. Results There were significant differences between serum BNP, cTnI, T3 levels in different HF function classification group(P0.05). The combined detection of 3 indicators of early HF sensitivity in patients is significantly higher than single detection(P0.05). Conclusion The combined detection of serum BNP, cTnI and T3 for HF early diagnosis, severity judgment reference has important clinical significance.
