The two types of cholesterol that exist are high-density lipoproteins (HDL) and low-density lipoproteins (LDL). HDL is referred to as the “good” cholesterol. It helps remove excess cholesterol from your body. LDL, or the “bad” cholesterol, creates plaques or buildup in arteries. This can lead to blocked arteries which can cause a heart attack or stroke. The brand names of statin drugs are: Crestor; Lescol; Lipitor; Mevacor; Pravachol; and Zocor. Study: Mr. Raymakers and colleagues at the University of British Columbia in Canada analyzed the association of statin drug from health records in their province and mortality.
