Original Article Gil et al Risks scores in acute coronary syndromes Arq Bras Cardiol. 2019; 113(1):20-30 populations which avoid high-risk patients. None of the RS performed well at predicting long-term prognosis. This is understandable given they were intended for the prediction of short-term mortality. The ProACS risk score proved to be an effective risk model, which performed incredibly well in this population, in both STEMI and NSTEMI patients. It is an intuitive risk score that requires only four easily obtainable variables. Its simplicity is rivalled only by the C-ACS, which has significantly underperformed in every aspect. The authors believe that ProACS is an appropriate and simple method to obtain adequate risk stratification regarding short-term prognosis that applies well to the Portuguese population.
