One of these systems is Thrombolysis In Myocardial Infarction (TIMI) scoring model that helps divide the patients into 2 groups of low risk (score 0-1) and high risk (score > 1) regarding adverse 30-day outcome.Ī study on 279 patients visiting ED showed that TIMI score is a valid tool for assessing 30-day mortality risk ( 8). Various clinical decision rules and scoring systems have been developed for this purpose ( 6, 7).Īn ideal model in this regard, should have high sensitivity and be able to predict the outcome accurately, using readily available clinical information. In cases that electrocardiogram (ECG), as the most available and rapid diagnostic tool, is not helpful in decision making (cases of unstable angina and Non-ST elevation MI), screening high risk patients for adverse outcomes would be very helpful. It seems that rapid diagnosis, and choosing the best treatment in the initial stages are of great importance in improving the outcome of CAD patients. It is predicted that until 2020, the number of CAD related deaths will exceed that of infectious diseases ( 5). About half of all deaths in developed countries and 25% of those in developing ones occur due to CAD ( 4). Although during the past decades, with development of preventive measures and improvement of diagnostic and therapeutic approaches, CAD related deaths have decreased by more than 40%, CAD still remains the largest killer of the US population ( 2, 3). ![]() ![]() Coronary artery disease (CAD) is a major health problem worldwide ( 1).
