Lecture Notes

In Chapter 4 we learned about the healthy function of our heart and our cardiovascular system, and in this lecture we're going to talk about the unhealthy cardiovascular system and the development of cardiovascular disease, and the first thing to know about cardiovascular disease is that it's actually a group of different diseases that affect the heart and the blood vessels, and not a single disease. Cardiovascular disease is a prevalent disease, like we just saw, and it's the leading cause of death in the United States today, and on the next slide we'll see the types of cardiovascular disease that most commonly lead to death.
