Cholesterol alone is completely harmless
Contrary to popular belief that LDL cholesterol alone is a high risk factor for vascular disease, it is now known that at least one other factor is necessary.
Only whon the same time the lipoprotein (a) in the blood is elevated, there is a danger that vessels will become clogged and the risk of heart attack, arteriosclerosis, dementia, vascular occlusion of the extremities and stroke will increase. Lipoprotein (a) is a substance that enables the transport of fats in the blood. It has a very similar construction to LDL cholesterol.
Comparative values of people with high LDL cholesterol levels of about 400 were already collected in 1990.
The results show that elevated cholesterol alone could not cause vascular changes. Only when lipoprotein (a) was also elevated (by more than 30) did a risk arise for people.
