2.6 - Cholesterol

A high level of cholesterol in the blood increases the risk of a cardiovascular complication, either an infarction or a cerebral vascular accident.

Cholesterol breaks up into " good " and " bad " cholesterol:

Total cholesterol = " good " cholesterol + " bad " cholesterol.

Good cholesterol is called HDL-cholesterol (HDL for High-Density-Lipoprotein), because it is the heaviest cholesterol and thus the least likely to penetrate into the wall of the artery.

Bad cholesterol is called LDL-cholesterol (LDL for Low-Density-Lipoprotein), because it is composed of small and light particles and thus it can easily penetrate into the wall of the artery.

At present physicians take the LDL-cholesterol rate as the basis to evaluate the cardiovascular risk of their patient and to adapt their medication.

The values of normality of the cholesterol rate are provided in the table below. It must be remembered that the measurement of cholesterol is carried out on an empty stomach, in the morning.

Category of patients
Value of introduction of the dietetic processing
Target value
Value of introduction of the drug therapy value
Target value
Men < 45 years or not post-ménopausal women, without factor of risk
> 2.2 g/l
< 1.6 g/l
Not in first intention
 
Men < 45 years or no menopausal women not, without factor of risk after failure of dietetics (6 months)
 
 
> 2.2 g/l
< 1.6 g/l
Subjects having at least a factor of risk
> 1.6 g/l
< 1.6 g/l
> 1.9 g/l
< 1.6 g/l
Subjects having at least two other factor of risk
> 1.3 g/l
< 1.3 g/l
> 1.6 g/l
< 1.3 g/l
Subjects having a coronary disease
> 1.3 g/l

< 1 g/l

> 1.3 g/l
In spite of the dietetics followed during 3 months.

< 1 g/l

Thresholds of intervention and value targets LDL-cholesterol to be reached.

These values of normality are variable according to the physiological and pathological conditions and also according to the existence of other factors of cardiovascular risk.
