26,861 initially healthy women, aged 45 years or older at the start of the study, were followed for approximately 11 years to determine the association between high density lipoprotein-cholesterol or apolipoprotein A-I levels and cardiovascular disease across a range of low density lipoprotein-cholesterol levels.
The study found:
(a) Those with the lowest high density lipoprotein-cholesterol (HDL-C) had an 119% increased risk of cardiovascular disease compared to those with the highest high density lipoprotein-cholesterol (HDL-C).
(b) Those with the lowest apolipoprotein A-I levels had an 58% increased risk of cardiovascular disease compared to those with the highest apolipoprotein A-I levels.
(c) The above associations associations were found for high density lipoprotein-cholesterol (HDL-C) with coronary events among women with a range of low density lipoprotein-cholesterol levels (LDL-C) values.
The study shows that high levels of high density lipoprotein-cholesterol (HDL-C) are associated with lower rates of cardiovascular disease, no matter what the levels of low density lipoprotein-cholesterol (LDL-C) are.
The best way to raise your high density lipoprotein-cholesterol (HDL-C) levels is to consume a diet rich in saturated fat. See here, here and here.
