How do we get heart disease?

I am doing a project in school about heart disease and i need to get answers on these questions: how do you get it? how do you prevent it?And how do you get rid of it?

for some its heredity for others is how they eat

Eating pizza
Eating hamber
Going to McDonald
You can get it from bad diet, high cholesterol, worry can cause heart disease. These are just a few of the reasons.
By eating anything that taste good
By eating Lots of fats and Oils...it blocks the Heart from pumping the Blood through the Body so it caues Heart attack too
The first four answers did not mention smoking, the greatest cause of heart attacks in the UK. Diet, high cholesterol and fatty products all contribute.
you get heart disease by foods high in fat and a lot of it is hereditary. you prevent it by low fat diets. you treat it with medications to lower your cholesterol.
