People with ‘bad' cholesterol within the recommended limits may still be exposed to the risk of heart attack. An international team of researchers, coordinated by specialists from the University of Chalmers Technology in Sweden, identified two types of particles in the blood that can contribute to inflammation and deterioration of blood vessels, regardless of cholesterol accumulation.
Why heart attacks can still happen even when bad cholesterol is low
Even when bad cholesterol is brought down to healthy levels, some people remain at risk of heart attacks, and scientists may have discovered why. Researchers identified two types of fat-carrying particles that appear to promote inflammation and damage blood vessels through mechanisms beyond cholesterol buildup.
A study by Chalmers University and Harvard shows that particles TRL and Lp(a) maintain inflammation and risk of heart attack even with controlled LDL cholesterol.
A new clue has been discovered to reveal why the risk of a heart attack remains even though LDL cholesterol levels, called so-called bad cholesterol, have been lowered to a normal range. Research shows that not only LDL, which is known to accumulate fat in blood vessels, but also particles and lipoprotein (a) that carry triglycerides are involved in biological processes related to inflammation and vascular changes.
