A heart attack is a result of the death of heart tissues due to the loss of blood supply. A heart attack is also known as acute myocardial infarction that can be fatal sometimes. It is caused by the sudden occurrence of coronary thrombosis, which obstructs the blood supply to the heart (coronary artery), which leads to necrosis of the heart muscle tissue. When plaques build up in the blood vessel, it is known as atherosclerosis.
This plaque can break up, a blood clot can form and block the arteries leading to the ischemic heart disease, and the heart doesn’t get oxygen. The treatment of a heart attack includes immediate administration of medications that dissolve and prevent blood clots, dilate the blood vessel, and an angioplasty stenting to open the blocked artery.
