Abstract

BACKGROUND: The thrombolysis-in-myocardial-infarction risk score (TRS) is a validated risk-assessment tool based on randomized clinical trials. Its applicability to an unselected group of patients seen in general clinical practice may be limited as renal dysfunction was an exclusion criteria in the original trials upon which the TRS was determined. MATERIALS AND METHODS: Consecutive patients with non-ST elevation acute coronary syndrome were stratified based on renal function. Normal renal function was defined as a creatinine clearance (CrCl) of more than 60 ml/min, moderate renal dysfunction was defined as a CrCl of at least 30 ml/min but 60 ml/min or less, and severe renal dysfunction was defined as a CrCl of less than 30 ml/min. A TRS was calculated using the original seven criteria (TRS-7) which did not consider renal function. A second TRS was calculated using the original seven criteria plus the addition of renal dysfunction if the CrCl was 60 ml/min or less (TRS-8≤60). A third TRS was calculated using the original seven criteria plus renal dysfunction if the CrCl was less than 30 ml/min (TRS-80.05). At a calculated TRS of 6 or 7, the TRS-8
