Detailed explanation-1: -Myocardial ischemia occurs when blood flow to the heart muscle (myocardium) is obstructed by a partial or complete blockage of a coronary artery by a buildup of plaques (atherosclerosis). If the plaques rupture, you can have a heart attack (myocardial infarction).
Detailed explanation-2: -Coronary heart disease If your coronary arteries become narrow due to a build-up of atheroma, the blood supply to your heart muscle will be restricted. This can cause angina (chest pains). If a coronary artery becomes completely blocked, it can cause a heart attack. This is a medical emergency.
Detailed explanation-3: -Myocardial infarction (MI): It occurs when an area of the heart muscle (myocardium) is damaged or dies after blood supply is blocked. It’s the classic medical term for a heart attack. Coronary thrombosis: It occurs when a clot is formed in one of the arteries that supply blood to the heart muscle.
Detailed explanation-4: -A heart attack, also called a myocardial infarction, happens when a part of the heart muscle doesn’t get enough blood. The more time that passes without treatment to restore blood flow, the greater the damage to the heart muscle. Coronary artery disease (CAD) is the main cause of heart attack.
