CRP and congestive heart failure: As reported previously, at baseline, PBR correlated with inflammation markers (fibrinogen: r = 0.58, and C-reactive protein: r = 0.42), platelet count (r = 0.36), and measures of renal/liver function such as estimated glomerular filtration rate (r = −0.34), total bilirubin (r = −0.38), and albumin (r = −0.30) in CHF patients, all p < 0.05 [34].
