Аtherogenic index
The Atherogenic Index (AI) is a quantitative indicator used to assess atherosclerosis risk. With atherosclerosis, cholesterol and other substances are deposited on arterial walls, narrowing vessel lumen and disrupting blood flow.
Calculation Formula is as following:
AI = (Total cholesterol - HDL) / LDL
To fully assess the risk, other factors shall be taken into account, such as
- Genetic disposition;
- Mode of life:
-improper nutrition (high intake of trans fats, saturated fats), smoking, stress can lead to increased AI
-regular physical activity increases HDL levels and reduces LDL ones, which leads to a decrease in AI).
Other factors:
- Age (AI usually increases with age).
- Sex (in men, AI is usually higher than in women).
- Co-morbidity (diabetes, hypertension, thyroid diseases and other ones can increase AI).
