ST-segment depression in non-ST elevation acute coronary syndromes: Quantitative analysis may not provide incremental prognostic value beyond comprehensive risk stratification

Greater ST↓ is associated with other adverse prognosticators across the broad spectrum of non-ST-elevation ACS. Although the presence of any ST↓ is an independent predictor of 1-year mortality, its quantitative assessment is not as important as its mere presence when studied on the background of comprehensive clinical and biomarker evaluation in a nonclinical trial-based ACS population.
