Relationship between thyroid hormone sensitivity and risk of arrhythmia in patients with coronary heart disease
Objective To analyze the relationship between thyroid hormone sensitivity and the risk of arrhythmia in patients with coronary heart disease(CHD).Methods From January 2023 to September 2023,385 CHD patients were selected and divided into an arrhythmia group of 121 cases and a non arrhythmia group of 264 cases based on the occurrence of arrhythmia.The thyroid hormone sensitivity of the two groups was compared,and the correlation between thyroid hormone sensitivity and arrhythmia risk was analyzed,as well as its predictive value for arrhythmia risk.Results Compared with the non arrhythmia group,the thyroid feedback quantile index(TFQI),parameter thyroid feedback quantile index(PTFQI),thyroid stimulating hormone resistance index(TT4RI),and thyroid stimulating hormone index(TSHI)were than those lower in the arrhythmia group(P<0.05),while the free triiodothyronine/free thyroid hormone(FT3/FT4)were higher than those in the arrhythmia group(P<0.05).According to Spearman analysis,TFQI,PTFQI,TT4RI,TSHI were negatively correlated with arrhythmia(P<0.05),while FT3/FT4 was positively correlated with arrhythmia(P<0.05).Binary logistic regression analysis showed that high TT4RI and high TSHI were protective factors for arrhythmia in CHD patients(P<0.05),while FT3/FT4 was a risk factor for arrhythmia in CHD patients(P<0.05).Combined=TFQI+(-1.563-2.384)*PTFQI+(-0.152/-2.384)*TT4RI+(-2.027/-2.384)*TSHI+(9.820/-2.384)*FI3/FT4.receiver operating curve(ROC)curve analysis showed that TFQI,PTFQI,TT4RI,TSHI,FT3/FT4,and the AUC for predicting arrhythmia in CHD patients were 0.681,0.681,0.748,0.695,0.744,and 0.862,respectively.The sensitivity and specificity corresponding to the optimal critical val-ues were:TFQI was 66.1%,70.5%,PTFQI was 68.5%,68.2%,TT4RI was 100.0%,50.0%,TSHI was 90.1%,44.7%,FT3/FT4 was 49.6%,100.0%,and combined was 66.1%,94.3%.Conclusion The sensitivity of CHD thyroid hormones to TFQI,PTFQI,TT4RI,TSHI,FT3/FT4 is closely related to the risk of arrhythmia,and the combination has high predictive value for the risk of arrhythmia in CHD patients.
