Mild to moderate aortic stenosis is considered a relative contraindication to stress testing because patients with this condition may experience an increased risk of complications during exercise. In aortic stenosis, the left ventricle must work harder to pump blood through a narrowed aortic valve, and while these patients may still undergo stress testing under certain circumstances, caution is necessary. The exercise could potentially lead to symptomatic events such as angina, syncope, or even more serious complications due to the increased cardiovascular demand.

In contrast, acute myocardial infarction represents an absolute contraindication where the risks overwhelmingly outweigh any potential benefit of the stress test. Patients who are acutely ill or have severe systemic conditions like significant anemia or unstable conditions also fall into a category where stress testing is not advised, but they are often classified as absolute contraindications because of the immediate risks involved. Known left main coronary artery disease is another scenario typically regarded as an absolute contraindication due to the severe risk of acute coronary events occurring during stress. Therefore, while mild to moderate aortic stenosis does pose risks, it does not present the same level of immediate danger as the other conditions listed, making it a relative contraindication.
