The SAQ is a 19‐item, self‐administered questionnaire that has been validated for use in patients with CADs. The questionnaire is divided into several categories, including angina pectoris frequency, physical limitations (PL), angina stability (AS), treatment satisfaction (TS), and QOL. For each of these five categories, the scores range from 0 (most symptomatic) to 100 (least symptomatic).Ischemia in exercise‐induced ECG was defined as a newly developed horizontal or down‐sloping ST‐segment depression of ≥1 mm at 60–80 ms after J point. STD was defined as an additional ST‐segment depression of at least 1 mm below the resting value.
