![]() ![]() Variables are common to both clinical conditions. ST-segment elevation (1/3 and 2/3 of patients, respectively). The GRACE score was created and validated in a sample of patients with or without The final score may vary between 0 and 14 6. Heart rate >100 bpm, and systolic pressure < 100 mmHg adds 2 points each.Īge adds 2 points if between 65 and 74 years and 3 points if ≥75 years. Of previous infarction (or left bundle branch block esquerdo), major riskįactors (hypertension, diabetes, or dyslipidemia), weight 4 hours adds one point each. With the exception of age that adds points in two distinct strata. In brief, this score consists of eight dichotomic variables, The TIMI score was created and validated in a sample of patients with ST-segmentĮlevation myocardial infarction, and thus, has specific variables for thisĬlinical condition. The Killip classification 8 was applied at time of Myocardial necrosis markers, which is one of the components of the scores, wasĭefined as troponin above the 99th percentile 7. Serum creatinine levels were used to calculate the scores. Levels measured during the first 12 hours of hospitalization, and the first Patients' data on presentation in the emergency room, the electrocardiographicĮxams performed in the first six hours of hospitalization, troponin T or I In this study, the outcome predicted by both scores was in-hospital death. Participate in this registry, which did not occur. Predefined exclusion criterion in this study was the patient's refusal to In the presence of third-degree left bundle branch block, theĭiagnosis is based on the presented symptoms and on necrosis markers. Nitrates) in two contiguous leads and confirmed by elevation of myocardial With persistent ST-segment elevation of ≥ 0.1 mv (not relieved by ST-segment elevation myocardial infarction was defined as chest pain associated Hospital on the basis of the objective diagnostic criteria. RESCA was started in AugustĢ007 and includes patients consecutively admitted to the coronary unit of this Resolution 466/2012 of the National Health Council. Was approved by the Hospital's Research Ethics Committee, according to Our hospital and provided their signed informed consent document. Syndromes Registry (Registro de Síndromes Coronarianas Agudas - RESCA) of The patients who participated in this study were part of the Acute Coronary In this hospital cohort, with regard to in-hospital death prediction, theĭiscriminatory ability and calibration of the TIMI score was compared to those of Of the Acute Coronary Syndromes Registry (RESCA) and were admitted with thisĬondition. ST-segment elevation myocardial infarction, we studied the individuals who were part To determine which of the two scores has better performance in patients with Therefore, the TIMI scoreįor ST-segment elevation myocardial infarction 6 comprises variables that are more specific for this clinical These clinical conditions, validated in distinct samples. ![]() On the other hand, the TIMI score has distinct models for each of Thus, the same score is used inīoth conditions. The former clinical condition was predominant in the sample 2. The GRACE score was derived from a sample composed of a combination of patients withĪCS without ST-segment elevation and patients with ST-segment elevation myocardial The two models has better prognostic performance with regard to in-hospital With ST-segment elevation myocardial infraction it has not been established which of Patients with acute coronary syndromes without ST-segment elevation, and it wasĮvident that the GRACE score had better prognostic accuracy. Others 4, 5 have previously compared these two scores in In this context, the main risk scores have been Risk estimates have implicationsįor clinical management, particularly with regard to broad-spectrum diseases, suchĪs acute coronary syndromes (ACS). The individual probability of unwanted outcomes. Risk scores correspond to multivariate models used in clinical practice to estimate ![]()
