Cardiologist shares 8 dangerous cholesterol myths that could be harming your heart health: ‘Risk starts early…'

Cholesterol myths can put your heart at risk. Cardiologist Dmitry Yaranov busts 8 common misconceptions and shares what you really need to know.

When it comes to cholesterol, misinformation spreads faster than facts. Many people think cutting out all fats is the solution, or that cholesterol is only a problem if you’re overweight. In reality, these myths can be dangerous, leading to poor lifestyle choices and untreated health risks. Dmitry Yaranov, cardiologist, shares in his August 17 Instagram post 8 common cholesterol myths and explains what you really need to know.

1. Only high-risk people need testing

Lp(a) can be dangerously high even in healthy, young people. Everyone should get tested at least once.

2. Lp(a) is just LDL cholesterol

They share a similar shell, but Lp(a) carries extra proteins that make it far more atherogenic.

3. Diet and exercise can lower it

Lp(a) is almost entirely genetic. Lifestyle helps overall heart health, but barely affects these levels.

4. All tests are the same

Labs use different methods and units, so numbers aren’t always comparable. Context matters.

5. It’s not a proven risk factor

High Lp(a) directly causes plaque buildup and aortic valve disease.

6. Levels change often

They’re stable for life after childhood. If it’s high once, it stays high.

7. There’s nothing you can do

While options are limited now, powerful new drugs are in late-stage trials. Stay informed.

8. Only matters later in life

Risk starts early, as elevated Lp(a) can accelerate heart disease decades before symptoms appear.
