Myocardial blood flow measured with contrast echocardiography. Myocardial blood flow at rest (A) and after adenosine infusion (B) and cold pressor testing (C) in healthy controls and diabetic patients. Dot plots indicate median ± range. CPT = cold pressor test; MBF = myocardial blood flow. A Wilcoxon signed-rank test was used for within group comparisons of myocardial blood flow results (baseline versus sevoflurane). Changes in myocardial blood flow responses before and during sevoflurane administration were compared between controls and diabetics using a Mann–Whitney U test.
