My cardiologist recently told me the disease is mostly from Lipo(a) and small dense Ldl, that it took decades from being able to measure LDL and note the correlation to disease to be able to measure there more specific factors, and even more time to nail down the observations. Lipo(a) is genetic, apparently either you have it or not. Small dense ldl is caused apparently (not a biologist) from high triglycerides, one cause of which is high sugar diet.
