The population most susceptible to elevated co levels are those with coronary artery disease. Coronary artery disease is typically caused by the build-up of cholesterol-containing deposits in major arteries. The primary study used by the epa to set clean air standards for co was conducted on subjects with moderate to severe coronary artery disease, more than half of whom previously had heart attacks. To establish a baseline, participants engaged in mild exercise on a treadmill while measurements were made of the time it took to develop chest pain and a specific electrocardiogram signal that indicates insufficient oxygen supply to the heart. Subjects repeated this test after resting for about an hour while being exposed to elevated co levels ranging from 42 to 202 parts per million (mean of 117). After exposure, the amount of time spent exercising before the onset of chest pain decreased.2, and the amount of time spent exercising before this specific electrocardiogram signal emerged decreased.1.
