Notes:
*
Dd-s denotes the displacement between the end systolic and end diastolic phase; Dr-d denotes the displacement between the random phase and the end diastolic phase; Dr-s denotes the displacement between the random and the end systolic phase. Values are given in mm as mean ± SD (95% CI).
Abbreviations: LCA, left coronary artery; RCA, right coronary artery; LAD, left anterior descending artery; LCxA, left circumflex artery; RMA, right marginal artery; SD, standard deviation; CI, confidence interval.
