Abstract:Objective To explore the relationship between the levels of serum high-sensitivity C-reactive protein (hs-CRP), cystatin C (Cys C), procalcitonin (PCT) and the prognosis of patients with pneumonia and heart failure. Methods Fifty patients with pneumonia and heart failure who admitted to the Second Affiliated Hospital of Wannan Medical College from March 2018 to June 2019 were included. The patients were followed up for six months and they were divided into good group (38 cases) and bad group (12 cases) according to the prognosis. Serum hs-CRP, Cys C and PCT levels were detected in the two groups, and the subject operating characteristic curve (ROC) was drawn to analyze the predictive value of each indicator for prognosis. The prognostic indicators of the patients were analyzed, including the changes of plasma brain natriuretic peptide (BNP), cardiac troponin I (cTnI) and left ventricular ejection fraction (LVEF). The correlation of hs-CRP, Cys C and PCT with prognostic indicators was analyzed by Pearson correlation. Results The levels of hs-CRP, Cys C and PCT, BNP and cTnI in the good group were lower than those in the bad group, and LVEF was higher than that in the bad group (P < 0.05). The AUC of hs-CRP, Cys C and PCT were 0.784, 0.723 and 0.792, respectively. The AUC of the combination of the three levels was 0.893. Serum hs-CRP, Cys C and PCT were positively correlated with plasma BNP and cTnI content (r = 0.528, 0.607, 0.596; 0.623, 0.604, 0.653, P < 0.05), but negatively correlated with LVEF (r = -0.633, -0.628, -0.639, P < 0.05). Conclusion The levels of hs-CRP, Cys C and PCT in patients with good prognosis of pneumonia and heart failure are significantly lower than those with poor prognosis, and they had certain predictive value for prognosis. The combined predictive effect is the best. The serum hs-CRP, Cys C and PCT levels are positively correlated with plasma BNP and cTnI levels and negatively correlated with LVEF levels.
