An synthetic intelligence (AI)-essentially based blueprint for interpreting ECGs performed better than identical outdated approaches in detecting occlusive myocardial infarction (MI), essentially based on a belief presented at ESC Acute CardioVascular Care 2026, the annual congress of the Association for Acute CardioVascular Care (ACVC), a branch of the European Society of Cardiology (ESC).
In sufferers with suspected acute coronary syndrome (ACS), a particular substitute on an ECG, known as an ST elevation, is a hallmark that the patient might perhaps perhaps additionally simply enjoy an occlusion in a coronary artery. This create of coronary heart attack is identified as an ST-elevation myocardial infarction (STEMI) and it requires instant percutaneous coronary intervention to restore the coronary heart’s blood waft. In sufferers who construct no longer enjoy an ST elevation, the motive in the aid of the chest distress might perhaps perhaps additionally simply additionally be much less obvious and further exams are wanted to substantiate if the MI is resulting from an occlusion.
Presenter, Doctor Federico Nani from Central Hospital Bolzano, Italy, defined: “Many patients without an ST elevation have an occlusive MI, but it can be difficult for clinicians to quickly and accurately recognise this, leading to delays in providing emergency treatment. We investigated whether AI-based interpretation of the initial ECG could improve the accuracy of detecting occlusive MIs in the absence of an ST elevation to optimise patient management.”
This single-centre prospective belief incorporated 1,490 sufferers who had symptoms suggestive of ACS but without an ST elevation on the preliminary ECG. The mean age changed into once 63 years and 42 per cent had been female. Clinicians interpreted the preliminary ECG, tested stages of the cardiac biomarker troponin, and performed coronary angiography, when required, to diagnose occlusive MI in step with ESC Guidelines. In parallel, the preliminary ECG changed into once interpreted by a smartphone-essentially based CE-certified AI-ECG algorithm.
AI-essentially based ECG interpretation dominated out occlusive MI in 1,382 sufferers and detected it in 108 sufferers (7per cent). The AI-essentially based blueprint correctly identified obstructive MI in 84per cent of cases. Sensitivity changed into once 77per cent, specificity changed into once 99 per cent, and the unfavorable predictive worth changed into once 98 per cent. There had been 27 false negatives (2per cent) and 17 false positives (1per cent).
Per the identical outdated diagnostic pathway, occlusive MI changed into once dominated out in 1,207 sufferers in step with troponin stages, and 283 sufferers underwent coronary angiography to substantiate or exclude the diagnosis. General, human ECG-interpretation correctly identified occlusive MI in 42per cent of cases.
Doctor Nani concluded: “This simple, accessible AI-based approach demonstrated superior accuracy in identifying and excluding occlusive MI compared with conventional diagnostic pathways in patients without an ST elevation. The results of our single-centre study require further validation, but these findings suggest that AI ECG interpretation is a valuable addition to existing decision-making tools to improve early recognition and timely, effective treatment.”
The vitality of AI to again the administration of cardiovascular disease will be extra explored as the highlight theme of this twelve months’s annual ESC Congress, taking hassle from 28-31 August 2026 in Munich, Germany.
