Lipoprotein (a) LPA
In recent years, Lp(a) (Lipoprotein (a)) from serum has come into increased focus as an important risk factor for myocardial infarction, probably genetically determined. Lp(a) is not affected by diet, lifestyle or medication. It is therefore a good indicator in young people to predict the long-term risk of cardiovascular disease. Lp(a) is reduced in liver disease and alcoholism.
It is assumed that with a value of Lp(a) greater than 0.3 g/l, without other lipoprotein abnormalities, the risk of myocardial infarction doubles. If also LDL increased the risk is even five times higher.
For estimating the risk of myocardial infarction the determination of cholesterol, HDL cholesterol, LDL cholesterol Apolipoprotein A1
, B and Lipoprotein(a) are important. Determination of triglycerides is especially important to assess nutritional status, the effect of any underlying diseases, such as pancreatitis (inflammation of the pancreas).
