The study evaluated the association between cholesterol levels and 30-day death rates in 490 older patients admitted to hospital with ischemic stroke.
The study found that those with the lowest cholesterol levels, under 4.1 mmol/l (158 mg/dL), had a 117% increased risk of death compared with those with the highest cholesterol, over 5.2 mmol/l (201 mg/dL).
Linls to other studies:
Low cholesterol levels lead to a 20.2% increase in death rates in those who have had a stroke
