Researchers from Michigan State University have revealed that damage caused during cardiac arrest can be more severe than previously thought.
They found that cholesterol crystals released in the bloodstream during a cardiac attack or stroke can wreck artery linings much further away from the site of the attack, thus putting the patients at greater risk than previously thought.
Heart Attack - Overview
Heart attack is the death of the heart muscle due to loss of blood supply. Heart disease is the leading cause of death in the United States. Other names for heart attack include acute myocardial infarction, coronary thrombosis, and coronary occlusion.

"Cholesterol has been shown to expand when crystallizing and then be released into the circulation following a cardiac event," said Abela.
"We found that the flow of sharp-ended crystals in arteries damage the lining of arteries and decrease the ability of arteries to dilate properly at intervals far away from the site of the attack.
"These findings have important clinical implications. We found the original injury was being transmitted downstream.
"We may need to expand the testing that we have patients undergo to make sure more damage is not being done during a cardiac attack or stroke," he added.

Heart attack can cause symptoms such as Chest pain or discomfort, Shortness of breath and pain in neck, back, arm, or shoulder and is due to blockage of blood supply to the heart muscles
