An old anterior myocardial infarction (MI) refers to a historical event where the anterior myocardial tissue of the heart has been damaged due to ischemia, which is a lack of blood supply. This damage typically occurs when the left anterior descending coronary artery (LAD), which is a major artery that supplies blood to a large portion of the heart muscle, becomes blocked. The blockage can be due to a blood clot or other factors that restrict blood flow. When this happens, the part of the heart muscle that is no longer receiving adequate blood supply begins to die, resulting in a myocardial infarction. The term "old" in this context indicates that the infarction happened in the past and has since healed, leaving behind scar tissue. This scar tissue can affect the heart's function and electrical conduction system, potentially leading to complications such as heart failure or arrhythmias. read more >>
