Abstract:
Objective To study the susceptible factors of atherosclerotic stenosis before the coronary artery myocardial bridges.Methods The data from 88 myocardial bridge cases which received coronary angiography were statistically analyzed.Sixty-seven cages which suffered from atherosclerofic stenesis in proximal of the myocardial bridges were recruited into group A,and the other 21 cases which suffered no atherosclerotic stenosis or from atherosclerotic stenosis in distal of the myocardial bridges were mcmited into group B.Difference of the age,gender,length of myocardial bridge,systolic blood pressure (SBP),diastolic blood pressure (DBP),pulse pressure (PP),the oppression degree of myocardial bridge (Nobel classification),fasting plasma glucose (FPG),and blood fat,and so on,in two groups,were observed and statistically analyzed.Results The difference of the Nobel classification,SBP and PP in two groups showed a statistical significance (P＜0.05).While the difference of the age,gender,length of myocardial bridge,DBP,FPG,total cholesterol,low-density hpoprotein in two groups showed no statistical significance (P＞0.05).A further regression analysis suggested that Nobel classification and PP had a correlation with the comphcation of stonosis before the myocardial bridge (r=3.0569,0.9740,P＜0.05).Conclusions High blood pressure cases are liable to suffer from myocardial bridge.Myocardial bridges themselves trend to promote or accelerate the atherosclerotic stenosis of the coronary arteries before.them.The oppression degree of myocardial bridge and PP has a correlation with the complication of stenosis before the myocardial bridge,while has no correlations with age,gender,bloodfat,SBP,DBP,FPG,length of myocardial bridge,and so on.
