Key result
ECG criteria identify occlusive NSTE-ACS lesions to enable early PCI and improve outcomes.
Why the study?
The STE and NSTE ACS paradigm may be imperfect, prompting the need to identify NSTE-ACS patients with occlusive or prognostically unfavorable coronary lesions using ECG criteria for timely PCI.
Can specific ECG criteria identify patients with NSTE-ACS who have occlusive coronary lesions requiring early percutaneous coronary intervention?
Can specific ECG criteria identify patients with NSTE-ACS who have occlusive coronary lesions requiring early percutaneous coronary intervention?
Specific ECG criteria may identify a subset of NSTE-ACS patients with occlusive coronary lesions who would benefit from emergent percutaneous coronary intervention.
Since patients with occlusive coronary artery thrombosis benefit more from emergency reperfusion, after the widespread introduction of thrombolytic therapy, the concept of Q-wave and non-Q-wave myocardial infarction was replaced by the concept of ST-segment elevation (STE) and non-STE (NSTE) acute coronary syndrome (ACS). But at present, due to the spread of mechanical reperfusion, this concept does not seem to be fully perfect. The electrocardiographic (ECG) diagnostic method allows, among patients with NSTE-ACS, to identify a group of patients with occlusive and/or prognostically unfavorable hemodynamically significant coronary lesions, as well as to provide them with timely percutaneous coronary intervention as early as possible and to improve outcomes. This article rationales changing approaches to the management of patients with NSTE-ACS and analyzes in detail the currently known ECG criteria for occlusive and/or prognostically unfavorable coronary lesions.

Pereverzeva et al. (2024) conducted a review in Non-ST-segment elevation acute coronary syndrome (NSTE-ACS). Electrocardiographic (ECG) diagnostic criteria was evaluated. Electrocardiographic criteria can identify patients with NSTE-ACS who have occlusive or prognostically unfavorable coronary lesions, enabling early PCI to improve outcomes.
