Cholesterol Crystals Linked to Cardiovascular Attacks

By R&D Editors | March 27, 2009

A Michigan State University researcher has shown cholesterol crystals can disrupt plaque in a patient’s cardiovascular system, causing a heart attack or stroke.
 
The findings by a team led by George Abela, chief of the cardiology division in MSU’s College of Human Medicine, could shift the way doctors and researchers approach cardiovascular attacks.
 
What Abela and his team found is that as cholesterol builds up along the wall of an artery, it crystallizes from a liquid to a solid state and then expands.
 
‘As the cholesterol crystallizes, two things can happen,’ Abela said. ‘If it’s a big pool of cholesterol, it will expand, causing the cap of the deposit to tear off in the arterial wall. Or the crystals, which are sharp, needle-like structures, poke their way through the cap covering the cholesterol deposit, like nails through wood.’
 
The crystals then work their way into the bloodstream. It is the presence of this material, as well as damage to an artery, that disrupts plaque and puts the body’s natural defense mechanism – clotting – into action, which can lead to dangerous, if not fatal, clots.
 
Abela and his team studied coronary arteries and carotid plaques from patients who died of cardiovascular attacks. When comparing their findings against a control group, they found evidence of cholesterol crystals disrupting plaque.
 
The breakthrough in discovering the crystals’ impact came after Abela and colleagues found a new way to preserve tissue after an autopsy, using a vacuum dry method instead of an alcohol solution. The previous method would dissolve the crystals and prevent researchers and doctors from seeing the impact.
 
Abela also has found that cholesterol crystals released in the bloodstream during a cardiac attack or stroke can damage artery linings much further away from the site of the attack, leaving survivors at even greater risk. The research means health care providers now have another weapon in their arsenal against cardiovascular diseases.
