Abstract
Background: Non-ST elevation acute coronary syndrome (NSTE-ACS) patients are complex and varied population. Primarily thrombolysis in myocardial infarction (TIMI) risk score was developed to guide therapy and assess the short term (14 days) prognosis of these patients. However, few studies have evaluated the long term prognostic significance of TIMI risk score after revascularization. This study aims at assessing the long term prognostic significance of TIMI risk score, 36 months after revascularization in NSTE-ACS.Methods: This was a retrospective observational cohort study of consecutive NSTE-ACS patients (n=150) treated by percutaneous coronary intervention between January 2017 to June 2017 in a tertiary care center. TIMI risk score was calculated for each patient at admission. The primary endpoint was a composite of MACE (death, repeat target-vessel revascularization, and non-fatal recurrent MI) at the end of 36 months of follow up. Clinical secondary endpoints included the individual components of the primary endpoint, death, nonfatal recurrent MI, and repeat target vessel revascularization.Results: Baseline characteristics for 150 participants were as follows, age 56±9.5 years, 78.7% male, 25% diabetics, 82% hypertensives, and 36% had hypercholesterolemia. The event rates of the primary endpoint and its components after 36 months were 26.6%. Event rates increased significantly as the TIMI risk score increased as determined by regression analysis (p=0.004). The relative risk increased by 66% as the TIMI risk score increased from low risk category (TIMI score 0-2) to high risk (TIMI score 5-6).Conclusions: TIMI risk score can be used for long term prognostication of NSTE-ACS patients after revascularization, and thus can be used by clinicians for therapeutic decision making.
