RESUMO
Objective:To investigate the role of serum CX3CR1 in the diagnosis of coronary artery stenosis and in the evaluation of prognosis after percutaneous coronary intervention.Methods:A total of 101 patients with coronary artery stenosis (≥ 50% stenosis) confirmed with coronary angiography (CAG) in Haiyang People's Hospital from January 2018 to May 2019 who were followed up till May 2021 were included in the observation group. Thirty-four healthy individuals who underwent physical examination during the same period were included in the control group. Patients in the observation group were divided into an in-stent restenosis group (ISR group, n = 28) and a non-ISR group ( n = 73). The expression of CX3CR1 was detected. The incidence of adverse cardiac events was calculated. The sensitivity, specificity, and area under the curve (AUC) plotted for the use of CX3CR1 to diagnose coronary artery stenosis and predict adverse cardiac events were evaluated. Results:The expression of CX3CR1 in the observation group was (3.95 ± 1.05) μg/L, which was significantly higher than (2.30 ± 0.65) μg/L in the control group ( t = 2.87, P < 0.05). The receiver operating characteristic curve analysis showed that the AUC, sensitivity, and specificity of the use of CX3CR1 in diagnosing coronary artery stenosis were 0.892, 75.2%, and 88.2%. The incidence of non-fatal myocardial infarction, angina pectoris, heart failure, and cardiac death in the ISR group was significantly higher compared with the non-ISR group ( χ2 = 8.06, 7.17, 8.06, 7.17, all P < 0.05). The receiver operating characteristic curve analysis results showed that the AUC value of CX3CR1 in predicting non-fatal myocardial infarction, angina pectoris, heart failure, and cardiac death were 0.786, 0.895, 0.997, and 0.887, respectively. Conclusion:CX3CR1 is highly expressed in coronary artery stenosis, which can provide a reference for the diagnosis and prognostic evaluation of coronary artery stenosis.
RESUMO
Objective Objective to investigate the changes of D-dimer and hypersensitivity C reactive pro-tein(CRP)in patients with acute exacerbation of chronic obstructive pulmonary disease(AECPOD)and their effects on prognosis.Methods From January 2014 to January 2016,104 cases of AECOPD patients were en-rolled in the study.According to the prognosis,they were divided into death group and survival group.D-di-mer and CRP were detected and the concentration changes were observed.Results There was no significant difference in CRP and D-dimer between the two groups on day 1 after admission(P> 0.05).While On the third day,the fifth day and the end of discharge,the concentrations of CRP and D-dimer in the death group were significantly higher than those in the survival group(P<0.05).Conclusion The continuous elevation of D-dimer and CRP suggests that the prognosis of AECOPD patients is poor,so the concentrations of D-dimer and CRP can reflect the severity of the patient′s condition and is helpful in the prognostic estimation.
