This study investigated the association of cholesterol levels and the risk of death from heart disease. The study included 4,066 men and women who were followed for five years.
The study found:
(a) Those with the lowest cholesterol levels (less than 4.15 mmol/L [160 mg/dL]) had the highest rate of death from coronary heart disease.
(b) Those with the highest cholesterol levels (more than 6.20 mmol/L [240 mg/dL]) had the lowest rate of death from coronary heart disease.
