How can we treat coronary heart disease? (OCR 21st century Biology)

Well, what is coronary heart disease?Coronary arteries are blood vessels that supply the heart muscle with food and oxygen With these nutrient, these muscle cells can respire and release energy for muscle contraction These arteries can become blocked overtime by fatty deposits like cholesterolMuscle cells deprived of nutrients and die How do we treat it?
