Overview

Epidemiological studies have shown that high concentrations of HDL (over 60 mg/dL) have protective value against cardiovascular diseases such as ischemic stroke and myocardial infarction. Low concentrations of HDL (below 40 mg/dL for men, below 50 mg/dL for women) are a positive risk factor for these atherosclerotic diseases.

Data from the landmark Framingham Heart Study showed that for a given level of LDL, the risk of heart disease increases 10-fold as the HDL varies from high to low. Conversely, for a fixed level of HDL, the risk increases 3-fold as LDL varies from low to high.

Epidemiology and Demographics

Epidemiological data showed the significant association of low HDL level, as an independent factor, with the development of CHD. And that for each 1% decrease in HDL level, there is increase in the risk of CHD development by 2-3%.[1]

A large epidemiological has been set out to determine the prevalence of low HDL 11 European countries. The study population includ 8545 patients receiving treatment for dyslipidaemia, Low HDL-cholesterol was present in 33% of men and 40% of women, with very low HDL-cholesterol present in 14% (both genders combined).[2]
