The Systemic Immune-Inflammation Index May Predict the Coronary Slow Flow Better Than High-Sensitivity C-Reactive Protein in Patients Undergoing Elective Coronary Angiography

Table 4

Spearman’s rho correlation analysis between the mean TFC and inflammation-based indicators.

Indicator	Mean TFC
	r value	value
PLR	0.484	<0.001
NLR	0.600	<0.001
hsCRP	0.671	<0.001
SII	0.725	<0.001

hsCRP, high sensitivity C-reactive protein; NLR, neutrophil-to-lymphocyte ratio; PLR, platelet-to-lymphocyte ratio; SII, systemic immune-inflammation index; TFC, TIMI frame count.
