Abstract:
Objective:To investigate the predictive value of serum cholinesterase(CHE)and soluble growth stimula-tion gene 2 protein(sST2)for short-term death in patients with myocardial infarction and heart failure.Methods:A total of 100 patients with myocardial infarction and heart failure admitted in Nanjing Benq Hospital between March 2021 and March 2023 were screened.After 6-month follow-up,patients were grouped according to pres-ence of death.Multivariate Cox regression was used to analyze the factors associated with death during 6-month follow-up in patients with myocardial infarction and heart failure.The predictive value of CHE,sST2 and their combined detection for short-term death in patients with myocardial infarction and heart failure was analyzed by receiver operating characteristic(ROC)curve.Kaplan-Meier survival curve was used to compare short-term sur-vival rate between myocardial infarction and heart failure patients with different CHE and sST2 levels.Results:During 6-month follow-up,46 cases died.Compared to those in survival group,patients in death group had sig-nificant higher heart rate(HR)[(82.20±8.09)beats/min vs.(71.54±6.97)beats/min],mean arterial pressure(MAP)[(126.58±5.38)mmHg vs.(104.79±4.94)mmHg]and sST2[(76.48±4.82)ng/ml vs.(40.62±4.96)ng/ml],and significant lower CHE[(3.47±0.26)IU/L vs.(5.07±0.80)IU/L](P＜0.001 all).Multivariate Cox regression showed that HR(HR 1.046,95％CI 1.002～1.092,P=0.040),MAP(HR 1.988,95％CI 1.298～2.455,P＜0.001),and sST2(HR 1.068,95％CI 1.014～1.125,P=0.013)were independent risk factors for short-term death in patients with myocardial infarction and heart failure,while CHE was its independent protec-tive factor(HR=0.252,95％CI 0.145～0.561,P=0.023).ROC curve analysis indicated that the area under the curve(AUC)of CHE,sST2 and their combination for diagnosing short-term death in patients with myocardial in-farction and heart failure was 0.609(95％0.504～0.707),0.630(95％0.525～0.726)and 0.939(95％0.871～0.977)respectively,and the diagnostic efficacy of combined detection was significantly higher than CHE and sST2 alone(Z=5.814,5.524,P＜0.001 all).Kaplan-Meier survival curve showed that the survival rate of patients with low CHE level was significantly lower than that of patients with high CHE level,and the survival rate of pa-tients with high sST2 level was significantly lower than that of patients with low sST2 level(Log-rank x2=2.415,2.354,P＜0.001 all).Conclusion:CHE and sST2 were independent influencing factors for death during 6-month follow-up in patients with myocardial infarction and heart failure;their combined detection had good predictive value for short-term death in these patients.
