Abstract
To observe the changes of neutrophil gelatinase associated apolipoprotein (neutrophil gelatinase associated lipocalin), lipoprotein associated phospholipase A2 and inflammatory cytokine hypersensitive C-reactive protein in patients with coronary heart disease and to explore the correlation between serum lipoproteinassociated phospholipase A2, neutrophil gelatinase associated lipocalin, hypersensitive C-reactive protein and the degree of coronary artery disease in patients with coronary heart disease. 200 inpatients in cardiovascular department of our hospital were divided into coronary heart disease group (n=153) and control group (n=47) according to coronary angiography. The serum levels of lipoprotein-associated phospholipase A2, neutrophil gelatinase associated lipocalin and hypersensitive C-reactive protein were measured. According to the Gensini score, the patients in the CHD group were divided into mild, moderate, severe and extremely severe groups. The changes of serum lipoprotein associated phospholipase A2, neutrophil gelatinase associated lipocalin and hypersensitive C-reactive protein was analyzed. At the same time, the relationship between the levels of serum lipoprotein associated phospholipase A2, neutrophil gelatinase associated lipocalin, hypersensitive C-reactive protein and the degree of coronary artery disease was discussed from the three aspects of coronary artery stenosis and Gensini score and the value of combined detection in the diagnosis of coronary heart disease. The serum levels of lipoprotein associated phospholipase A2 lipoprotein associated phospholipase A2 , neutrophil gelatinase-associated lipocalin, hypersensitive C-reactive protein and Gensini score in the coronary heart disease group were significantly higher than those in the control group (p<0.01). The serum levels of lipoprotein-associated phospholipase A2, neutrophil gelatinase associated lipocalin and hypersensitive C-reactive protein in extremely severe coronary artery disease group were significantly higher than those in moderate to severe disease group, mild disease group and control group (p<0.05) and those in severe disease group were significantly higher than those in mild and moderate disease group and control group (p<0.05). The area under the curve of combined detection of lipoprotein-associated phospholipase A2, neutrophil gelatinase associated lipocalin and hypersensitive C-reactive protein in the diagnosis of coronary heart disease reached 0.859. The serum levels of lipoprotein associated phospholipase A2, neutrophil gelatinase associated lipocalin and hypersensitive C-reactive protein are significantly increased in patients with coronary heart disease and are closely related to the severity of coronary artery disease, which can be used to evaluate the severity of coronary artery disease. The diagnostic rate of combined detection of serum lipoprotein associated phospholipase A2, neutrophil gelatinase associated lipocalin and hypersensitive C-reactive protein for coronary heart disease can reach 0.859, which can provide important clinical guidance value.
