  1. Data are presented as mean ± standard deviation or n (%).
  2. BSA, body surface area; GLS, global longitudinal strain; LAD, left anterior descending artery; LVEDD, left ventricular end-diastolic dimension; LVEF, left ventricular ejection fraction; LVESD, left ventricular end-systolic dimension; LVMI, left ventricular mass index.
  3. *P derived from the analysis of variance or the Kruskal–Wallis test, †P < 0.05 versus no stenosis, ‡P < 0.01 versus no stenosis.
