Box Plots demonstrating the relationship between the ultra-high sensitivity troponin I (u hscTnI) levels (log transformed) and (A) Normal and limited coronary blood flow response to intra-coronary acetylcholine (normal response defined as an increase in coronary blood flow in response to acetylcholine by ≥50%), (B) Normal and limited microvascular dilation to intra-coronary adenosine (normal coronary flow reserve ≥2.32), (C) Normal and limited coronary dilation in response to intra-coronary acetylcholine (normal response defined as an increase in coronary artery diameter in response to acetylcholine by ≥0%), (D) Normal and limited coronary artery dilation in response to intra-coronary nitroglycerin (normal response defined as an increase in coronary artery diameter in response to nitroglycerin by ≥20%).
