Correlation of Neutrophyl-Lymphocyte Ratio, Vessel Score based on Sullivan Scoring System, and Troponin in Acute Coronary Syndrome Patients

Acute Coronary Syndrome (ACS) is one of the highest causes of death globally, with the number of deaths reaching more than 9 million people in 2016. Therefore, a fast and accurate ACS diagnosis is needed. This study aimed to determine the relationship between the neutrophil-lymphocyte ratio, the number of coronary artery lesions evaluated by angiography, and troponin I in ACS patients Material and Methods: This research is an analytic observational with a retrospective cross-sectional design. Sampling was carried out using a total sampling technique and obtained 87 samples that met the inclusion and exclusion criteria for the 2019-2020 period at Dr. Soetomo Regional General Hospital Surabaya. The correlation between the number of coronary artery lesions and the neutrophil-lymphocyte ratio to troponin I levels were respectively analyzed using chi-square and spearman-rho with SPSS ver. 25. Results: The results showed a moderately significant correlation between the neutrophil-lymphocyte ratio and troponin I levels (p =0.003, rs = 0.319). While the correlation analysis between the number of coronary artery lesions and the vessel score on troponin I showed insignificant results (p = 0.525), which means that the number of coronary artery lesions was not correlated with troponin I. Conclusion: This study concludes a significant correlation with moderate correlation between the neutrophil-lymphocyte ratio and troponin I. However, there is no significant correlation between the number of coronary artery lesions assessed by the Sullivan and troponin I levels.
