Has anyone ever taken a cardiopulmonary stress test? Since I had Covid about 6 months ago, I enough energy to get myself through the work week along with increased shortness of breath and chest tightness (all symptoms of my asthma) Whether or not the symptom increase is in fact related to Covid is not as important to me as improving my symptom control again. I have severe asthma and currently take trelegy, singular and Nucala. After a negative CXR and PFT, the doctor recommended a cardiopulmonary stress test. I have never had this test and I don’t know much about it. Can anyone share their experience and whether or not the test results helped the MD improve the symptom control?
