A MULTIVARIATE ANALYSIS OF MYOCARDIAL BRIDGING WITH NO FIXED OBSTRUCTION

Abstract

One of the main diagnosis in the case of Coronary Artery Disease (CAD) is the myocardial bridging. This myocardial bridging can be either typical or atypical angina pectoris. Moreover, it can occasionally manifest as Acute Myocardial Infarction (AMI) or sudden death. Among the common public, this condition of myocardial bridging is relatively common and it is a benign pathology and the
patients at low risk for CADcan be affected by this. But when it is symptomatic, it can appear to be stable or unstable angina, ventricular and supraventricular arrhythmias, sudden death and AMI; however, AMI and sudden death are rare. This condition is
rarely diagnosed because a few patients present the symptoms and there are unavailability and constrained utilization of the diagnostic techniques. Hence, the treatment methods and pathophysiological mechanisms are not completely revealed. It is reported that there is a majordiscrepancy in the prevalence of myocardial bridging between the conventional angiography (average 5%, range 0.5% to 16%)10,11 and the autopsy findings (average 33%, range 15% to 85%)12. Therefore, the detection of myocardial bridging is important as it is related to the cardiomyopathy and ischemic heart disease.
