A portion of the heart’s blood vessels encased in flesh is mostly suggestive of myocardial bridges. The blood vessels that supply blood flow to the heart are called coronary arteries, which normally travel in the connective tissue beneath the epicardium. When a segment of a coronary artery travels within the myocardium, the bundle of myocardial fibers is called a myocardial bridge, and the coronary artery that travels under the bridge is called a mural coronary artery. In clinical practice, when the mural coronary arteries are severely compressed during the systolic phase of each cardiac cycle, distal myocardial ischemia occurs, resulting in symptoms such as angina pectoris and arrhythmia. Currently, the treatment of this disease is usually based on beta-receptor antagonists such as metoprolol and avoidance of positive inotropic drugs such as isosorbide nitrate. If you suffer from myocardial bridge, it is recommended that you visit a regular hospital to avoid delays.
