Objective:To analyze correlations among levels of C-reactive protein(CRP),white blood cell count(WBC),neutrophil to lymphocyte ratio(NLR)and severity of coronary heart disease complicated with pulmonary infection.Methods:A total of 80 patients with coronary heart disease complicated with pulmonary infection admitted to the hospital from June 2021 to June 2023 were selected as the study group,and 70 healthy subjects in the hospital during the same period were selected as the control group.The levels of CRP,WBC and NLR were detected.The clinical pulmonary infection score(CPIS)was used to evaluate the severity of pulmonary infection in these patients with coronary heart disease.The levels of CRP,WBC and NLR were compared between the two groups and among the patients with different severity of pulmonary infection.Spearman correlation analysis was used to analyze the correlations among the CRP,WBC,NLR levels and the severity of coronary heart disease patients with pulmonary infection.Results:The levels of CRP,WBC and NLR in the study group were higher than those in the control group,and the differences were statistically significant(P<0.05).The levels of CRP,WBC and NLR in the patients with severe pulmonary infection were higher than those in the patients with moderate and mild pulmonary infection,those in the patients with moderate pulmonary infection were higher than those in the patients with mild pulmonary infection,and the differences were statistically significant(P<0.05).The levels of CRP,WBC and NLR were positively correlated with the severity of coronary heart disease complicated with pulmonary infection(r>0,P<0.05).Conclusions:The levels of CRP,WBC and NLR are positively correlated with the severity of coronary heart disease complicated with pulmonary infection.
