Abstract

Objective: To investigate the predictive value of coronary artery electrocardiogram in evaluating PCI-related myocardial injury among athletes with coronary heart disease.

Method: This study included 100 athlete patients with coronary heart disease treated at our hospital from January 2020 to October 2021. Participants were categorized into an observation group and a control group based on the presence of PCI-related myocardial injury. We recorded clinical data, relevant specific indicators, and changes in coronary artery electrocardiograms, analyzing predictive value using Receiver Operating Characteristic (ROC) curves. Logistic regression was utilized to identify risk factors influencing myocardial injury, and cardiac events were monitored post-procedure.

Results: No significant differences were noted in general data such as age and BMI between groups (P > 0.05). The observation group exhibited longer balloon dilation times, greater stent lengths, and a higher number of stent implants than the control group (P < 0.05). Additionally, levels of cardiac troponin T (cTnT) and creatine kinase-MB (CK-MB) were elevated, with more frequent ST segment elevation and Q wave abnormalities in the observation group (P < 0.05). AUCs for balloon dilation time, stent length, stent number, cTnT, and CK-MB were 0.749, 0.764, 0.775, 0.823, and 0.687, respectively. Identified risk factors for PCI-related myocardial injury included balloon dilation time, stent length, stent number, ST segment elevation, Q wave abnormalities, cTnT, and CK-MB (P < 0.05). Three adverse cardiac events occurred in the observation group compared to none in the control group; however, this difference was not statistically significant (P > 0.05).

Conclusion: Factors such as balloon dilation time, stent length, stent number, ST segment elevation, Q wave abnormalities, cTnT, and CK-MB significantly influence PCI-related myocardial injury in athletes. Coronary artery electrocardiograms can accurately predict these injuries, highlighting the importance of this diagnostic tool in managing athlete patients undergoing PCI
