The coronary angiography and clinical study of myocardial bridge

Objective to investigate the incidece of myocardial bridge through coronary angiography,the clinical features of myocardial bridge,its clinical presentation,treatment,evaluation of efficacy,and prognosis.Methods Uses SPSS statistics software to make the statistical analysis,and counts date using chi-square analysis.Results the incidence of myocardial bridge through coronary angiography was 10.69%,Hypertrophic cardiomyopathy accounted for 10%,the diabetes accounted for 20.96%,hypertension accounted for 29.03%,Both non-hypertension and non-diabetes accounted for 50%,myocardial bridge which accounted in the left coronary artery accounted for major cases,in the right coronary arteryaccounted for small cases,There are 9 cases with atherosderosis stenosis at the same coronary artery.53 cases with atherosclerosis stenosis at the other coronary artery.The length of myocardial bridge was 8-31 mm,.Isolated myocardial bridge 43 cases(69.3%).Conclusion:(1)Myocardial bridge may cause myocardial ischemia symptoms,and nitrates agents may increase the reaction of myocardial bridge;(2)Myocardial bridge can continue to cause the formation of atherosclerosis,serious may even induse severe acute myocardial infarction;(3)Congenital development,left ventricular hypertrophy,hypertention and hypertrophic cardiomyopthy all had clinical correlation with myocardial bridge;(4)There are no significant correlation between blood glucose,blood fat,CRP,ESR,uric acid and myocardial bridge;(5)The first treatment for sympotomatic myocardial bridge is medication and surgery should be considered when medication has a poor result as we known,The stent therapy leads to poor result for long time.
