Quote from a May 2019 article, American Heart Association:
LDL cholesterol – the so-called "bad" cholesterol – is known to narrow arteries, which can lead to heart attacks and strokes. It's also now suspected of contributing to venous thromboembolism, new research suggests.
Quote from an NIH article:
Most adults should have a cholesterol test every 4 to 6 years. That’s because nearly 78 million American adults have high levels of the type of cholesterol that’s linked to heart disease and stroke.
Cholesterol is a waxy, fat-like substance that your body needs to function properly. It travels through your bloodstream to reach the cells that need it. Your cells use cholesterol for many important functions, like making hormones and digesting fatty foods.
But too much cholesterol in your blood can cause waxy buildup called plaques in blood vessels. “These plaques can eventually become inflamed and rupture, leading to a clot,” explains cholesterol expert Dr. Ronald Krauss at UCSF Benioff Children’s Hospital Oakland.
Of course, that one is dated February 2019 -- is 3 months old too "outdated" for you?
