Given the serious health risks associated with elevated Lp(a) levels, doctors are calling for the test to be covered by Medicare
Many cardiologists in Australia are calling for more testing for a marker of “bad cholesterol” known as Lp(a), which can cause sudden heart attacks in younger people and could be elevated in more than 5 million Australians. Despite this, many cardiologists are still not aware when to test for Lp(a) and there is currently no Medicare rebate for the test, which can cost patients up to $40.
Lp(a) is a lipoprotein that is similar in structure to LDL cholesterol, but it has an additional protein called apolipoprotein(a) attached to it. Elevated levels of Lp(a) in the blood have been linked to an increased risk of heart disease and stroke. Lp(a) is considered an independent risk factor for cardiovascular disease, and is thought to be primarily influenced by genetics, rather than lifestyle factors like diet and exercise.
Lp(a) can cause blood clots, which can lead to heart attacks or strokes, as well as contributing to plaque buildup in the arteries, which can further increase the risk of cardiovascular disease. Elevated Lp(a) levels may also be associated with an increased risk of aortic stenosis and aortic aneurysms.
Currently, Lp(a) testing is not routinely included in standard cholesterol screening tests. However, doctors may order this test if a patient has a family history of heart disease or if they have already been diagnosed with heart disease.
There are several ways to lower elevated levels of Lp(a) in the blood. Lifestyle changes such as eating a healthy diet low in saturated and trans fats, engaging in regular physical activity, and maintaining a healthy weight can all help to lower Lp(a) levels. Medications such as statins can also lower Lp(a) levels by reducing the production of LDL cholesterol. Niacin, a B vitamin, may also lower Lp(a) levels. Additionally, supplements such as Nattokinase, derived from a traditional Japanese fermented soy food, may also help to lower Lp(a) levels. Genetic testing may also be recommended if a patient has a genetic condition that causes high Lp(a) levels.
It’s important to consult with a healthcare professional before making changes to your diet or starting any new medication regimen. Given the serious health risks associated with elevated Lp(a) levels, doctors are calling for the test to be covered by Medicare for those at risk, particularly as it only needs to be done once in a person’s life.
