Abstract:
Objective The morphological and data characteristics of premature ventricular contraction(PVC)were obtained through dynamic electrocardiogram(DCG),and its correlation with new-onset major adverse cardiovascular events(MACE)was analyzed.Methods A total of 115 patients with PVC admitted to Huzhou First People's Hospital from January 2022 to January 2024 were retrospectively selected and divided into MACE group(n=31)and non-MACE group(n=84)according to the new-onset MACE.Collect the baseline data of patients,as well as DCG data such as the morphological and data characteristics of PVC.Collect the baseline data of patients,as well as DCG data such as the morphological and data characteristics of PVC.Multivariate Logistic regression was used to analyze the influencing factors of new-onset MACE in patients with PVC.The receiver operating characteristic(ROC)curve was drawn to analyze the predictive value of influencing factors for the risk of new-onset MACE in patients with PVC.Results There were statistically significant differences in gender,disease duration,QRS wave duration,PVC origin,PVC load,and Lown classification between two groups of patients(P＜0.05).Multivariate Logistic regression analysis showed that QRS wave duration(OR=1.070),PVC origin(OR=6.840)and PVC load(OR=2.583)were independent risk factors for new-onset MACE in PVC patients(P＜0.05).The ROC curve showed that the area under the curve for predicting new-onset MACE in PVC patients with QRS wave duration,PVC origin,and PVC load were 0.791,0.750,and 0.917 respectively.The predictive value of PVC load was the highest.Conclusion QRS wave duration,PVC origin and PVC load are related to new-onset MACE in PVC patients,and PVC load has a good predictive effect on the risk of new-onset MACE in PVC patients.
