Researchers at the University of Athens, Greece, report that they have, for the first time, measured temperatures inside patients' coronary arteries and linked elevated temperatures with a risk of myocardial infarction (MI).
The study included 90 patients whose coronary arteries were examined with a tiny thermometer attached to the tip of a catheter. Half were atherosclerosis-free and served as controls. Of the remaining half, 15 had stable angina, 15 had unstable angina, and 15 had suffered an MI within hours of the examination.
