Medians of the detected fluorescence intensity of endocardial vWF in the left atrial endocardium from the four groups from left to right as shown in Figure 5 were Control group: 30.8 (IQR 28.1–34.2), Subclinical 39.6 (IQR 31.8–59.6), CHF group: 46.0 (IQR 36.6–56.8), and ATE group: 44.7 (IQR 34.9–54.6). The gene discussed is VWF; the disease is congestive heart failure.
