Levels of so-called "good" cholesterol -- the kind that removes artery-clogging fat from the blood -- might be as important to the risk of stroke as the "bad" kind, researchers said Monday.
Researchers found that men who already had heart disease had up to twice the risk of suffering a stroke if their levels of "good" cholesterol were low, even if their "bad" cholesterol levels were normal.
The report, in the American Heart Association's journal Stroke, said their findings indicated that many men at risk of stroke were not getting the right treatment or advice.
High-density lipoprotein, or HDL, the so-called "good" cholesterol, carries fat away from the arteries, stopping it from being deposited on artery walls. Low-density lipoprotein, or LDL, does the opposite.
