The Predictive Value of 12 Lead Dynamic Electrocardiogram on the Prognosis of Patients with Myocardial Infarction
Objective:To explore and analyze the predictive value of 12 lead dynamic electrocardiogram on the prognosis of patients with myocardial infarction.Methods:From January 2022 to December 2022,110 patients with myocardial infarction who were hospitalized in the cardiovascular department of Qingyang People's Hospital in Gansu Province were selected as the study subjects.All patients underwent 12 lead dynamic electrocardiogram examination and recorded heart rate variability(HRV)indicators.The general data of the patients were investigated,the recurrence of prognosis was followed up and the correlation of prediction was analyzed.Results:110 patients were followed up until March 1,2023,with an average follow-up time of(6.50±0.41)months.There were 20 cases of recurrence(recurrence group),and the recurrence rate was 18.18%.There was no statistically significant difference in gender,smoking history,alcohol consumption history,age,and body mass index between the recurrence group and the non recurrence group(P>0.05).There was no statistically significant difference in high-density lipoprotein cholesterol,total cholesterol,triglycerides,low-density lipoprotein cholesterol,and fasting blood glucose between the recurrence group and the non recurrence group(P>0.05).The PNN50,RMSSD,SDNNI,SDANNI,and SDNN values of the recurrence group were lower than those of the non recurrence group(P<0.05).Spearman correlation analysis showed a negative correlation between prognosis recurrence and 12 lead dynamic electrocardiogram indicators such as PNN50,RMSSD,SDNNI,SDANNI,and SDNN(P<0.05).Conclusion:Recurrence after myocardial infarction is relatively common,and recurrent patients often show reduced heart rate variability on 12 lead dynamic electrocardiogram.12 lead dynamic electrocardiogram has good value in predicting recurrence in patients with myocardial infarction.
