Scan predicts heart attack risk
Scientists at the University of Edinburgh have developed a new tool for scanning the human heart for dangerous plaques. They believe that scanning the heart with this tool may make it easier to identify people who are at high risk of a heart attack.
In analyzing 40 patients who had recently had a heart attack, scientists combined using a “radioactive tracer” with high resolution images of the heart and blood vessels. Using this method, they were able to create a detailed picture of the heart with the dangerous plaques highlighted.
Findings showed that the scanning tool highlighted the plaque which caused heart attacks in almost 93 percent of the patients.
The study, published in the medical journal Lancet, is significant because it's the first time a scan has been able to locate danger zones in the heart. The scientists acknowledged that more studies are needed before they will be able to determine whether detecting dangerous plaques before a heart attack will doctors to save lives.
