As people become more aware of cardiovascular disease, more and more people are paying attention to their own health and early screening for cardiovascular disease. Those who have done coronary CTA or coronary angiography may have heard the term, “coronary artery myocardial bridge”, which sounds very high level, so what exactly is a coronary artery myocardial bridge? Let’s take a look at it now. There are three main vessels on the surface of the heart, called coronary arteries, the normal coronary vessels should be attached to the surface of the heart, but some people have a small section of coronary arteries, a small section of the coronary arteries hidden inside the heart muscle called the wall coronary arteries, this phenomenon is commonly known as myocardial bridges. Myocardial bridges are formed congenitally. For patients who have been diagnosed with myocardial bridges, more than 95% of them can be better controlled by taking medication, so there is no need to worry about the vast majority of cases. Patients with myocardial bridges may experience some symptoms, including chest tightness, increased heart rate, especially when the activity is intense, and sometimes chest pain. If the patient already has symptoms, it means that the compression of the coronary artery by the heart muscle is still relatively obvious, and it is best to carry out medication. Also, you should usually try to avoid strenuous activities, drinking strong tea, coffee and alcohol, etc., and avoid doing these things that can make the heart rate increase dramatically. At present, the main role of drugs for the treatment of myocardial bridges is to control the heart rate and reduce the compression of the heart muscle on the blood vessels, such as beta-blockers, long-acting calcium antagonists, especially diltiazem such drugs can relieve the symptoms of myocardial bridges, commonly used are metoprolol (Betaxolol), Bisoprolol (Kangxin, Bosu) and so on. If myocardial bridge patients usually do not have symptoms, you can also temporarily do not take drugs, but betalactam these drugs for a long time to eat patients or have a certain protective effect, so it is recommended that patients who have the conditions of long-term medication, which is safer.
