ABSTRACT
Objective To investigate the significance of combined detection of homocysteine(Hcy) and ischemia modified albu‐min(IMA) in serum to the diagnosis of acute myocardial infarction(AMI) .Methods The serum levels of Hcy and IMA were detec‐ted in 80 patients with acute myocardial infarction ,60 patients with angina pectoris and 40 healthy subjects(control group) ,and the results were statistically analyzed .Results The concentration of Hcy and IMA in AMI patients was significantly higher than which in the control group ,the difference is statistically significant(P<0 .05);the sensitivity of the Hcy+ IMA combined diagnosis was higher than that of the single project .Hcy and IMA was positively related(P<0 .05) .Conclusion The combined detection of Hcy and IMA levels in patients with acute myocardial infarction has a good effect on early diagnosis and monitoring ,and it is worth popularizing .
ABSTRACT
Objective To investigate the correlation between serum lipoprotein associated phospholipase A2 (Lp‐PLA2) level and severity of coronary artery stenosis in the patients with coronary heart disease(CHD) and its clinical significance .Methods A total of 243 cases of CHD and suspected CHD were divided into the high‐risk group(at least 1 coronary artery vessel stenosis >50% ,n=102) and low‐risk group(single coronary artery vessel stenosis≤50% ,n=141) according to the coronary angiography re‐sults .The clinical data were collected and Lp‐PLA2 level was detected by ELISA .Results The serum Lp‐PLA2 level in the high‐risk group was significantly higher than that in the low‐risk group ,and the difference was statistically significant(P<0 .01) ,the sensitivity of Lp‐PLA2 for judging the high‐risk patients with CHD was 86 .3% ,the specificity was 96 .6% ,and the overall diagno‐sis accuracy was 98 .0% .Conclusion Lp‐PLA2 can better assess the risk of CHD patients and the serum Lp‐PLA2 level can reflect the severity of coronary artery lesion .
