Key result
A high neutrophil to lymphocyte ratio was independently associated with severe coronary artery disease (OR 3.308) in patients undergoing elective coronary angiography.

Does high neutrophil to lymphocyte ratio predict the severity of coronary artery disease in patients undergoing elective coronary angiography?
Odds Ratio: 3.308 (95% CI 1.645–6.653)
p-value: p=0.001
High neutrophil to lymphocyte ratio is independently associated with angiographically severe coronary artery disease, suggesting its potential utility as a simple predictive biomarker.
Das et al. (2023) conducted a cross-sectional in Coronary artery disease (n=160). High neutrophil to lymphocyte ratio (NLR) vs. Low neutrophil to lymphocyte ratio was evaluated on Severe coronary artery disease (Gensini score ≥30) (OR 3.308, 95% CI 1.645-6.653, p=0.001). A high neutrophil to lymphocyte ratio was independently associated with severe coronary artery disease (OR 3.308) in patients undergoing elective coronary angiography.
