inappropriate changes in the plasma lipoproteins. A change of diet and drugs
may help this condition. The blood pressure may be excessively high in some
individuals. This can be dangerous and lead to heart failure and stroke. Here
again, drugs may be used to alleviate the condition. Heart failure needs to
be treated promptly otherwise permanent disability or death may occur. The
peripheral blood vessels can also become diseased. For example, the veins
returning blood to the heart may develop faulty valves leading to varicose
veins.
