There has been an increasing call for employing ultrashort exercise activity questionnaires as a clinical “vital sign”. To-date, this has not been applied to patients undergoing cardiac stress testing. We evaluated 1136 patients who completed a one-item exercise questionnaire before undergoing stress SPECT myocardial perfusion imaging (MPI). This question asked patients to grade how much they exercise during daily life on a 11-point scale (0 = none, 10 = always). Patients were divided into four exercise activity groups based on their response: no, low, moderate, and high exercise activity. The results of this questionnaire were compared with patients’ clinical risk profile, mode of stress testing (exercise vs pharmacologic), and exercise treadmill duration. We noted a stepwise inverse relationship between exercise activity and patients’ frequency of hypertension, diabetes, and obesity (P
