Figure 3. Relationship between AF prevalence and LVEF-associated left atrial (LA) size/volume in the clinic.

Figure 3.

LA size/volume serves as a surrogate for atrial structural remodeling in clinical setting. In the absence of HF (hypertensive patients), LA size/volume is commonly normal or near normal and is associated with a low prevalence of AF. The mean LA size/volume is much greater in the setting of HF, but is relatively smaller in HFpEF when compared with HFrEF patients. AF prevalence increases dramatically in patients with HF, more so in patients with preserved LVEF vs. reduced LVEF (HFpEF vs. HFrEF, respectively). Please see Table 1 and 2 for the numerical data.
