Correlation of TIMI score with severity of coronary artery disease in acute coronary syndrome

Abstract

Background: ACS presents as wide range of clinical ailments that requires prompt treatment to avoid unforeseen circumstances. As noninvasive strategy, TIMI risk assessment is a widely accepted tool for risk stratification of ACS patient to initiate timely management. Purpose of the present study is to determine the association of TIMI score in predicting the severity of coronary artery disease in ACS. Methodology: A cross-sectional study was conducted in specialized tertiary care cardiac hospital on 255 patients from January 2021 to June 2021. For all patients, TIMI score calculated based on all the seven variables. Confidentiality of the participants was maintained. Ethical approval was obtained from review board of concerned hospital. Data was analyzed on SPSS version 23.0. One way ANOVA was used to compare categorical variables. Chi square test used to reveal difference in proportion to three TIMI groups. Results: Finding show that ST segment deviation was evident in 51.5% patients. Out of 37 patients in group-III with ST segment changes, 91.8% were found of having significant CAD. Results show that in group-III, 54.1% had significant three vessel CAD compared to 17.6% group-II & 7.5% group-I patients. Also, p-value of <0.001 depict significant association between TIMI score and severity of CAD. Conclusion: A significant association from this study gives a notion that TIMI score is valuable tool in clinical setting to make urgent decision regarding the management of CAD. Also, it was concluded from current study that patients with higher TIMI score had additional risk of three vessel CAD and left main vessel CAD in patients with ACS.
