Abstract
Association between CD69 and EGR1 levels and coronary heart disease (CHD) patients without reflow after percutaneous coronary intervention (PCI) was investigated. Data of 156 patients undergoing PCI from September 2014 to December 2016 in People's Hospital of Hunan Province were analyzed, and they were divided into 72 cases in reflow group (group A) and 84 cases in no-reflow group (group B) according to the patient's postoperative blood flow. Another 70 volunteers undergoing normal physical examination in the same period were selected as control group (group C). The venous blood was extracted from patients before operation, at 5 min, 2 h and 6 months after operation, the serum CD69 and EGR1 levels were detected with flow cytometry and RT-qPCR methods, and association between CD69 and EGR1 levels and postoperative blood flow recovery was analyzed. CD69 expression before and 2 h after operation in group A was significant (P<0.05), and a difference in patients at 6 months after operation between group A, B and group C (P<0.05). The CD69 expression in group A was significantly lower than that in group B (P<0.05), but in group B was significantly higher than that in group C (P<0.05). The EGR1 expression in group A was significantly higher than that in group B (P<0.05), but in group B was significantly lower than that in group C (P<0.05). Multivariate logistic regression analysis revealed that CD69 (OR=6.424, P=0.025) and EGR1 (OR=3.684, P=0.013) were independent risk factors for patients without reflow after undergoing PCI. After undergoing PCI in CHD patients, if there was an increase in CD69 level and a significant decrease in EGR1 level in the early postoperative period, the patient may be suspected of having no-reflow and checked in time to improve the patient's therapeutic effect.
