CRP and atherosclerosis: The NLR, as a marker of inflammation, may play an important role in the pathogenesis of atherosclerosis.26 In addition, the NLR is an important predictor of mortality in patients with acute coronary syndrome, and both C-reactive protein and NLR levels have positive correlations with the no-reflow phenomenon in STEMI patients treated with primary PCI.27 Kaya et al.28 reported that a higher NLR in patients with STEMI treated via primary PCI was associated with increased mortality and major cardiac events.
