Hello Thanks for posting here. Usually the arteries of the heart are located on its surface. Sometimes they may pierce the heart muscle and pass through it. Because if this, when the heart contracts, the artery also gets compressed. This is called myocardial bridge. It implies that there is no clot or blockage in the artery but it gets compressed by muscle contractions. So they do not cause any harm to the patient. Since he is 45, your doctor has started him on aspirin and statin. If the lipid profile is normal, Ldl less than 100, and his other arteries show no blocksthen he can be kept off statins. But statins are very beneficial drugs with low side effect profile. So i suggest to continue taking them. regards.
