  1. *: by one-way ANOVA. Different superscript letters between the groups indicate significant difference (at 0.05 level) by Tukey's multiple comparison procedure.
  2. †: Group 1 = normal control; Group 2 = DCM only; Group 3 = DCM plus ADMSC; Group 4 = DCM plus sildenafil; Group 5 = DCM plus combined sildenafil and ADMSC.
  3. FABP = femoral arterial blood pressure; LVEF = left ventricular ejection fraction.
