Lecture Notes

Coronary heart disease is another type of cardiovascular disease, and as you saw in the pie graph it's the greatest killer of all the cardiovascular diseases. About one in two men and one out of every three women will develop coronary heart disease at some point in their life. It's most commonly the result of atherosclerosis like we just talked about, or the narrowing of the two coronary arteries, the arteries that supply blood to your heart, and when you have narrowing of these arteries, the oxygen-rich blood cannot reach the heart where it's needed to maintain normal function. When that happens it can result in heart attack, angina, heart failure, and we'll talk about these in the next few slides.
