HDL cholesterol removes excess fat and other types of cholesterol from the arterial system. Hemorrhagic stroke occurs when a blood vessel in the brain breaks open and is different than the more common thrombotic stroke caused by an abnormal blood clot. This study showed that the risk of thrombotic stoke was twice as likely in those with cholesterol levels over 280 compared to those at 230. The report concluded that optimal cholesterol level for overall stroke prevention was around 200. Some overzealous Foundation members have been pushing their cholesterol levels way below 180.
Triglycerides combine a fatty acid and glycerol.
Elevated triglyceride levels predispose a person to atherosclerosis and abnormal platelet aggregation. Nutrients that may lower elevated triglyceride levels include high doses of fish oil, garlic, and niacin. The high cost and inconvenience of regular blood testing prevents many people from being tested as often as they should be. Another problem with blood testing is that different labs often produce varying readings from the same blood specimen, making the results of regular testing difficult to interpret. The Life Extension Foundation receives blood- test results for evaluation from members who sometimes use different laboratories every time they are tested.
