Figure 2. Individual values of (A) endothelial (eNOS) and (B) inducible nitric oxide synthase (iNOS) activity in the right atrial appendage of patients in the groups with left ventricular ejection fraction (LVEF) >60% and LVEF <35%, reported as relative cDNA absorbance. The symbols to the right of individual values are the mean ± SEM. N = 10 patients in each group.
