New heart scan technology can help predict heart attack risk

Myocardial infarction is a healthy killer for humans. British researchers have developed a new heart-scanning technology that uses radiotracers and high-resolution images to detect fatty plaques in the cardiovascular system, so as to identify high-risk factors that can cause MI.

Researchers at the University of Edinburgh in the United Kingdom reported on the 11th in the British medical journal Lancet that they found that fatty plaques in the heart arteries ruptured to form blood clots and block blood vessels, which is the main cause of myocardial infarction. Finding these plaques early can help prevent heart attack. In the new study, researchers injected two radioactive tracers into the blood of some patients with heart disease, and then used positron emission tomography to display high-resolution images of intracardiac fat plaques in order to determine the patient's myocardial infarction. risks of.

This new technology accurately identifies fat plaques in the cardiovascular system and judges the risk of rupture. According to reports, a total of 40 heart disease patients participated in the trial, and the accuracy of this new technique for judging myocardial infarction was as high as about 93%. Researchers believe that it is necessary to conduct larger clinical trials to confirm their effectiveness.

Mark Devik, a cardiologist at the University of Edinburgh who led the study, said that although not all fat plaques can cause myocardial infarction, early detection of these plaques and finding out that the risk of rupture is higher will help doctors judge patients. Risk of myocardial infarction and thus take appropriate precautions.
