I suggest that all cholesterol measures on their own don’t give you enough information.
You need to evaluate every marker you can with respect to your risk of heart attack or coronary disease.
Some key ones follow…
Coronary artery calcium
Unsourced from my notes - Coronary artery calcium (CAC) scans are created by using computed tomography (CT) scans, which are a type of X-ray scan, to detect the presence and quantity of coronary artery calcification (the warning signs of atherosclerosis). A CAC test reveals both the location and quantity of calcium located in three of the main coronary arteries. The scan provides a score which represents your risk. The lower the better! This score will change over time, and is known to increase with age, so it is important to record it regularly (in a manner that balances the downsides of the X-ray radiation — ask your doctor what’s best for you). Atherosclerosis is a disease of ageing, and that means your risk is increasing over time. If you are aged 50 or above and have never had one — work with your doctor to get one performed.
Test your ApoB (“A-PO-B”)
Unsourced from my notes - Stop using your LDL-C as your primary risk assessment tool (The “LDL” value too commonly called the “bad” cholesterol), and start tracking your ApoB. ApoB is a particular type of molecule attached to the types of lipoproteins carried by your LDL (and VLDL) that are the most likely to enter the arterial wall and lead to plaque formation. You need to know how many of these atherogenic particles you have present in a given volume of you blood — this drives your risk. Your ApoB value is influenced by diet and lifestyle and can be controlled with pharmaceutical intervention and possibly through certain forms of supplementation.
Do you have elevated Lpa (”L-P-little-A”)?
Unsourced from my notes - Lipoprotein-a is a particle which carries cholesterol, fats and proteins and is made by your body, and how much of it you make is inherited. Elevated levels of Lpa increase your risk of a heart attack or stroke as they are known to cause atherosclerosis. You certainly need to know if you carry the genetic risk factor, and the earlier the better (i.e. get this test done as early as possible)! Levels of Lpa don’t change much over one’s lifetime, so testing it once is enough in most cases! Know your Lpa status, and better know your risk, and whether or not you should modify your diet, lifestyle and treatment options.
Track your inflammation with C-Reactive Protein (CRP)
Unsourced from my notes - At its roots, atherosclerosis is known to be intimately connected with inflammation. In fact, it is often damage to the arterial wall that attracts the formation of plaque in the first place. This damage occurs over time, and is known to be increasingly likely with high blood pressure and high blood glucose levels. CRP is a very common and relatively low cost blood test that can be easily ordered up by your doctor, and should be tested annually at the very least. High levels of CRP are indicative of increased risk of cardiovascular disease, and once again can be influenced by changes in diet and exercise. If you have the option, go for the high-sensitivity CRP (hsCRP) test if possible!
