The superiority of anyone has not yet been established.Īfter enrollment, all patients were evaluated clinically at first presentation. Several international reports have shown positive correlation of GRACE and TIMI risk scores with the severity of coronary artery disease but regarding the comparison of these scores in predicting the severity of coronary artery disease, the available international data is limited. 7 The segments are scored from 0.5 to 5 according to their anatomical importance and is multiplied by the score regarding the maximum degree of obstruction ranging from 1 to 100% and the points of the 14 segments are summed to yield a final score by using the following formula: Gensini Score = Sum of Scores (Score for% of stenosis × Score for vessel/vessels involved). 6 Gensini score calculates the severity of CAD from 14 coronary artery segments. 5 Vessel score describes significant coronary artery disease as ≥70% stenosis in any of the major epicardial coronary arteries or ≥50% stenosis in the left main coronary artery. 4 Vessel score and Gensini score are the two scoring systems which are being widely used in assessment of the severity of coronary artery disease. But estimating the possible severity of CAD by these scores before performing coronary angiography may change the therapeutic decision and the timing or intensity of interventions. Both the scores calculate the patient’s risk of mortality and they are not intended to identify the severity of coronary artery disease. This score has seven variables (Age, Prior CAD, Risk factors, History of Angina episodes in 24 h, History of Aspirin intake, ST segment deviation on ECG and elevated cardiac biomarker) with the scoring from 0 to 7. The TIMI score has been derived from Thrombolysis In Myocardial Infarction (TIMI) IIB trial and has also been published as online TIMI risk score calculator ( ). Creatinine, ST segment deviation on ECG and elevated cardiac biomarker) with the scoring from 2 to 372. This score has eight variables (Age, Heart Rate, Systolic BP, Killip Class of HF, Cardiac arrest at admission, S. The GRACE score has been derived from Global Registry of Acute Coronary Events (GRACE) registry and it has been published as an online risk calculator ( ). 3 These two scoring systems yield the scores from some clinical parameters obtained from patient’s history, physical examination and investigations during admission. The most popular risk scores are the GRACE and TIMI scores. Several risk scores are developed in predicting the outcomes in patients with acute coronary syndrome. Prognosis in patients with non-ST elevation acute coronary syndrome can be assessed by early risk stratification. 1 The incidence of non-ST elevation acute coronary syndrome to ST elevation myocardial infarction is increasing, probably as a result of demographic changes in the population, including progressively increasing numbers of older persons and higher rates of diabetes mellitus. Coronary artery disease (CAD) alone caused 7 million deaths worldwide in 2010 and it is an increase of 35% since 1990. This figure is expected to grow to 23.6 million by the year 2030. Cardiovascular diseases account for more than 17 million deaths globally each year.
