The ratio of ApoB to ApoA1 summarises cardiovascular risk in a single number. The lower the ratio, the better the balance between harmful and protective lipoproteins.
The ratio is one of the strongest single predictors of heart attack risk. It is used in international risk models (AMORIS, INTERHEART) and is not sensitive to fasting state.
What does low ApoB to ApoA1 ratio mean?
A low ratio is favourable.
What does high ApoB to ApoA1 ratio mean?
A high ratio raises cardiovascular risk and should prompt lifestyle change or medical assessment.
