Statins are used in patients with angina, even those who have a "normal" cholesterol level, because they make the fatty plaques stable and less likely to rupture. They are also useful in patients with unstable angina for the same reason. Statins in big doses slow the progression, and in some patients reverse, coronary heart disease. The target LDL-cholesterol level in patients with angina or unstable angina or previous heart attack is less than 2.0 mmol/l.
Statins also reduce the inflammation in arteries.
