Technology developed, determines early signs of heart attack
- Most heart attacks are caused by a build-up of plaque, a fatty deposit inside the artery, which interrupts the flow of blood.
- The technology uses algorithms to examine the fat surrounding coronary arteries as it shows up on computed tomography (CT) heart scans.
- Identifying inflammation in the arteries of the heart,will be enable one to tell which arteries will cause heart attacks.
A new method of analyzing images from CT scans can predict which patients are at risk of a heart attack years before it occurs, researchers say.
The technology, developed by teams at Oxford University and institutions in Germany and the United States, uses algorithms to examine the fat surrounding coronary arteries as it shows up on computed tomography (CT) heart scans.
The fat that gets altered when an artery becomes inflamed, serves as an early warning for what one of the researchers believes could be up to 30 percent of heart attacks.
“If you are able to identify inflammation in the arteries of the heart, then you will be able to tell which arteries will cause heart attacks,” Oxford Professor of Cardiovascular Medicine, Charalambos Antoniades, told Reuters.
“With the new technology that we have, we can achieve this by analyzing simple CT scans.”
Most heart attacks are caused by a build-up of plaque, a fatty deposit inside the artery, which interrupts the flow of blood.
Currently, CT scans tell a doctor when an artery has already become narrowed by plaque.
“We can say that your arteries are inflamed and a narrowing will be developed five years down the line. So maybe you can start preventive measures to avoid this formation of the plaques,” Antoniades said.
Heart disease and stroke are the two biggest causes of death worldwide.
“Although we have not estimated the exact number of heart attacks that we can prevent, we could potentially identify at least 20 or 30 percent of the people before they have one,” Antoniades said.
An Oxford University spin-off company is now developing a service to analyze CT scans from across the globe in around 24 hours.
The research was published in late August in medical journal The Lancet.
