This is a very basic summary - and doesn't actually discuss deviations from a normal lipid panel, how they interact, or which should be treated.

There are hundreds of summaries to improve understanding available from reputable health care systems, hospitals, etc - and hundreds of studies that provide the next levels.

Anyone with heart disease should do their own research for basic knowledge - and, IMO should not listen to one person or one video, especially if it is as general as this video.

Most commenting on this site should obtain an advanced lipid panel, a CAC scoring, and should prepare their material in a clear manner to speak with their PCP, and, if warranted a cardiologist.
