Detection of Coronary Artery Disease by an Erectile Dysfunction Questionnaire

Figure 1

Mean score of IIEF in the non-CAD group and 3 CAD groups. CAD, coronary artery diseases; SVD, single-vessel disease; 2VD, two-vessel disease; 3VD, three-vessel disease. We indicate severity of CAD according to number of involved vessels. Figure shows that as CAD becomes more severe, mean of IIHF decreases, and severity of ED increases.
