Figure 1 Comparisons of Coronary Vasomotor Responses to ACh in AMI Patients and Control Subjects
Comparisons of vasomotor responses to acetylcholine (ACh) in acute myocardial infarction (AMI) patients treated with a sirolimus-eluting stent (SES) (n = 13) or bare-metal stent (BMS) (n = 16) and control subjects (n = 12). (A) Percent change in epicardial diameter of the left anterior descending coronary artery (LAD) from baseline in response to ACh. (B) Percent change in epicardial diameter of the left circumflex artery (LCx), a reference artery, from baseline in response to ACh. (C) Percent change in coronary blood flow (CBF) of the LAD from baseline in response to ACh.
