In summary, although blood cholesterol levels have not traditionally been considered a risk factor for stroke, careful consideration of the observational data is consistent with cholesterol being an important contributor to ischaemic stroke risk, as might be expected given the very strong relationship between coronary heart disease risk and lipid levels. The observational data also raise the possibility of an increased risk of haemorrhagic stroke with low blood cholesterol levels.
