No mention of ME (CFS) a very common and extremely disabling disease incorporating cardiomyopathy. Running treadmill tests on ME patients is very detrimental to them as post exertional malaise is a hallmark of the disease. Cardiologist should be aware of the exercise contraindication.Also ME patients have reduced ejection, low blood volume, orthostatic intolerance, and increased cardiac disease mortality. When ME patients die of heart disease, it is, on average, at an age 25 years younger than that of the whole population of people who die of heart disease.
