Hypercholesterolemia Why is atherosclerosis bad?
If the artery brought blood to the heart, people can have angina or a heart attack. Myocardial means relating to the heart muscle. Infarction means death of a tissue or organ. So a myocardial infarction or 'heart attack' is when blood flow to part of the heart stops. Then that part of the heart dies. Angina is when the blood flow is 'low' but not 'totally blocked'.
