Abstract:
Objective:To investigate the diagnostic value of electrocardiographic ST-segment changes for myocardial injury related to percutaneous coronary intervention.Methods:We included 60 patients who received percutaneous coronary intervention in Haining People's Hospital from January 2020 to February 2021 in this study. We detected serum troponin I level before and after treatment and recorded electrocardiographic ST-segment changes. Taking serum troponin I level as a reference, we divided these patients into myocardial injury and non-myocardial injury groups and analyzed the influential factors of myocardial injury.Results:Balloon inflation time and stent length were (85.6 ± 56.2) minutes and (25.2 ± 15.2) mm in the myocardial injury group, and they were (48.5 ± 39.2) minutes and (17.2 ± 8.2) mm in the non-myocardial injury group. There were no significant differences in balloon inflation time and stent length between the two groups ( t = -3.01, -2.42, both P < 0.05). The proportion of patients with electrocardiographic ST-segment changes was significantly higher in the myocardial injury group than in the non-myocardial injury group [(80.77% (21/26) vs. 5.88% (2/34), χ2= 34.95, P < 0.001). Multivariable logistic regression analysis results showed that electrocardiographic ST-segment changes were an influential factor of myocardial injury ( r = 69.25, P < 0.05). Conclusion:Electrocardiographic ST-segment changes are an independent influential factor of myocardial injury related to percutaneous coronary intervention. It can effectively judge the possibility of developing a myocardial injury and increase the safety of percutaneous coronary intervention.
