Abstract：【Objective】To explore the clinical value of microvolt T wave alternation(MTWA) in predicting major adverse cardiovascular events(MACE) in patients with chronic heart failure.【Methods】A total of 100 patients with CHF admitted to Baoji Hospital affiliated to Xi'an Medical College from December 2019 to December 2021 were selected and divided into MACE group(n=28) and non-MACE group(n=72) according to whether they had MACE. All patients underwent ambulatory electrocardiogram examination,and the risk factors for MACE in patients with CHF were analyzed using univariate and multivariate logistic regression analysis. The receiver operating characteristic(ROC) curve was used to evaluate the value of MTWA in predicting MACE in patients with chronic heart failure. 【Results】The age ≥65 years old,BMI ≥25 kg/m2,history of arrhythmia,smoking history,NYHA classification Ⅳ,history of hypertension,overwork history,and the proportion of V1 lead maximum MTWA(MTWAmax),maximum heart rate(MTWApeakhr),and average MTWA(MTWAoverall) in the MACE group were higher than those in the non-MACE group(P<0.05). ROC curve analysis showed that MTWAmax,MTWApeakhr,and MTWAoverall had higher values for predicting MACE in patients with CHF,with areas under the curve of 0.903,0.686,and 0.825,respectively(P<0.05). Logistic regression analysis showed that age ≥65 years old,history of arrhythmia,smoking history,NYHA classification Ⅳ,history of hypertension,overwork history,MTWAmax≥24.706,MTWApeakhr≥1.586,and MTWAoverall≥1.489 were all risk factors for MACE in patients with CHF(P<0.05). 【Conclusion】The application value of ambulatory electrocardiogram MTWA in predicting MACE in patients with chronic heart failure is high,and it is worthy of clinical reference.
