The PRD (+) group had a higher value of C-reactive protein level (median: 1.80 mg/dL [0.31-3.26] vs 0.20 mg/dL [0.06-0.81], P = 0.013) and creatine kinase-muscle/brain isoenzyme (median: 60 IU/L [28-75] vs 17 IU/L [13-26], P < 0.001) and a lower level of left ventricular ejection fraction (42.7 ± 7.2% vs 48.8 ± 9.4%, P = 0.041) than the PRD (-) group.
