Heart disease is a broad term for any condition affecting your heart and arteries.  Some forms of heart disease are the main cause of heart attack and stroke.  A heart attack occurs when your heart muscle suddenly becomes injured.  The muscle cells of your heart start dying off, and you're no longer able to pump blood to your body.  If the heart muscle is not able to pump blood to your brain and other vital organs, you can end up with a stroke.  This can cause permanent brain damage or death.

What are some of the causes of heart disease?
user
Causes of heart disease range from lifestyle factors to medical conditions.  Tobacco smoke is a major contributor to heart disease, as are other types of smoking.  The consumption of a large amount of saturated fat (or "red meat" as it's often called) can lead to a higher risk of heart disease.  There's also a higher risk of heart disease in people with high blood pressure.  People with high blood pressure are also more likely to have a stroke or heart attack.  Other lifestyle factors also contribute to heart disease, including obesity, lack of exercise, high blood sugar, or diabetes.
