Insights
Single culprit artery occlusion may lead to more electrocardiogram (ECG) misinterpretations in ST-segment elevation myocardial infarction (STEMI) patients during automated analysis. This finding impacts diagnostic accuracy in emergency care.
Area of Science:
- Cardiology
- Medical Diagnostics
- Artificial Intelligence in Medicine
Background:
- Automated electrocardiogram (ECG) interpretation aids in diagnosing ST-segment elevation myocardial infarction (STEMI).
- The accuracy of automated ECG interpretation can be influenced by various patient-specific factors.
- Understanding these factors is crucial for improving diagnostic algorithms.
Purpose of the Study:
- To investigate the relationship between the culprit artery and the diagnostic accuracy of automated ECG interpretation in STEMI patients.
- To determine if specific culprit artery occlusions are associated with higher rates of ECG misinterpretation.
Main Methods:
- A retrospective cohort study of adult STEMI patients from January 2017 to December 2020.
- Analysis of the association between culprit artery occlusion and ECG misinterpretation using chi-square or Fisher exact tests.
- Evaluation of automated ECG interpretation accuracy.
Main Results:
- The overall rate of automated ECG misinterpretation in STEMI patients was 26.5%.
- Single culprit artery occlusion was significantly associated with increased ECG misinterpretation compared to multiple occlusions (31.3% vs. 12.9%, P=0.045).
- No significant correlation was found between ST segment changes in specific leads and ECG misinterpretation.
Conclusions:
- Single culprit artery occlusion may increase the likelihood of automated ECG misinterpretation in STEMI.
- These findings suggest that the number of occluded culprit arteries is a factor affecting the reliability of automated STEMI diagnosis.
- Further research may refine algorithms to account for culprit artery characteristics.
Objective:
This study aimed to analyze the association between the culprit artery and the diagnostic accuracy of automatic electrocardiogram (ECG) interpretation in patients with ST-segment elevation myocardial infarction (STEMI).
Methods:
This single-centered, retrospective cohort study included adult patients with STEMI who visited the emergency department between January 2017 and December 2020. The primary endpoint was the association between the culprit artery occlusion and the misinterpretation of ECG, evaluated by the chi-square test or Fisher exact test.
Results:
The rate of misinterpretation of the automated ECG for patients with STEMI was 26.5% (31/117 patients). There was no significant correlation between the ST segment change in the four involved leads (anteroseptal, lateral, inferior, and aVR) and the misinterpretation of ECG (all P > 0.05). Single culprit artery occlusion significantly affected the misinterpretation of ECG compared with multiple culprit artery occlusion (single vs. multiple, 27/86 [31.3%] vs. 4/31 [12.9%], P = 0.045). There was no association between culprit artery and the misinterpretation of ECG (P = 0.132).
Conclusion:
Single culprit artery occlusion might increase misinterpretation of ECG compared with multiple culprit artery occlusions in the automatic interpretation of STEMI.
