Data are means ± standard deviations; numbers in parentheses are ranges. The AHA 17 segments model of left ventricular were assigned to 3 major coronary arteries territories: LAD (segments 1, 2, 7, 8, 13, 14, and 17), RCA (segments 3, 4, 9, 10, and 15), LCX (segments 5, 6, 11, 12, and 16); four myocardial regions: anterior (Segments 1, 7, 13, 17), septum (Segments 2, 3, 8, 9, and 14), inferior (segments 4, 10, and 15), and lateral (segments 5, 6, 11, 12, and 16); and basal (segment 1–6), middle (segment 7–12), and apical (segment 13–16) for the analysis. MBF, myocardial blood flow; LAD, left anterior descending coronary artery; LCX, left circumflex coronary artery; RCA, right coronary artery.

P-values were derived from one-way ANOVA.
