Predictive value of ambulatory electrocardiographic monitoring for prognosis assessment in patients with acute myocardial infarction after percutaneous coronary intervention LI Aizhen（Department of Electrocardiogram，Mingxi County General Hospital， Sanming Fujian 3652OO，China）

[Abstract]ObjectiveTo investigate the eficacy of ambulatory electrocardiographic monitoring in evaluating the prognosis of patientswith acute myocardial infarction（AMI） treated by percutaneous coronary intervention （PCI）.MethodsClinical data of 8O AMI patients treated byPCI were retrospectively analyzed.The incidence of adverse cardiovascular and cerebrovascular events was observed during a 1-year folow-up period.Based on the follow-up outcomes， patients were divided into a good prognosis group （ n=57 ） and a poor prognosis group （ n= （204号 23）.Electrocardiogram （ECG）parameters of both groups were recorded，while their prognosis predictive value was assessed ResultsIn the good prognosis group，adverse cardiovascular and cerebrovascular events occurred in 5 cases including 3 cases with repeated revascularizations，1 case with malignant arrhythmia，and 1 case with hypertension.In the poor prognosis group，adverse events included8 cases of recurrent myocardial infarction， 5cases of repeated revascularization，7cases of heart failure，and 3 cases of cardiogenic shock.No statistically significant difference in QT dispersion was observed between the two groups （ P>0.05 ）.However，statistically significant diferences were noted in the following parameters：standard deviation of all normal-to-normal（NN） intervals（SDNN），ratio of low-frequency to high-frequency power （LF/HF），turbulence slope，and turbulence

onset （all P<0.01 ）. ROC curve analysis revealed that the combined detection of these parameters yielded an AUC value of O.969，surpassing the prognosis predictive value of any single parameter. ConclusionAmbulatory electrocardiographic monitoring demonstrates significant predictive value for the prognosis of AMI patients treated by PCI. It makes accurate assessment of their risk for adverse events.
