I also have high cholesterol. A total cholesterol above 240 puts you in the high risk zone. You're right that statin drugs don't prevent heart attacks - directly. What they do is lower your cholesterol so that your arteries stay open. High cholesterol will clog your arteries so that the blood cannot flow through them. This can lead to stroke or heart attack. Please listen to your doctor and take the statin drugs - unless you want to die soon. For more info, check out the American Heart Association website.
