In what way is a diseased coronary heart artery differ from a healthy one, and what are two ways to treat it?

A diseased coronary heart artery has fatty diposits (atheroma) that narrow the lumen, and block bloodflow. As the coronary arteries primarily serve to nourish the heart, this can weaken it and if it remains untreated, can lead to heart attack. We can treat this disease using stents or medications such as statins, which include aspirin and warfarin.
