ABSTRACT
This is a prospective clinical study, in which we applied the modern risk stratification strategies, such as the TIMI risk score of. acute coronary syndrome, [Thrombolysis in myocardial infarction], associated with unstable angina and non-ST segment elevation. For this purpose, 188 Yemeni patients were followed up in Al-Gamhuria Teaching Hospital in Aden for 4 years from January 2004 to January 2008. According to the TIMI risk score of ACS, the investigated patients were divided into 3 subgroups: high, intermediate and low risk patients. Coronary angiography, performed in all patients, proved that the correlation between the coronary findings and the clinical risk status was reflecting the benefit of using clinical predictors for early diagnosis. We concluded that the application of the more detailed TIMI risk score was proved to be an effective tool not only for early prognosis, but also for designing therapeutic strategies in patients presented with symptoms of UA/NSTEML
