Figure 6. — There is no correlation between serum ACE2 activity and the severity of diastolic dysfunction.

There was no correlation between serum ACE2 activity (expressed as U/ml serum) and left ventricular diastolic parameters (E/A, n=30, panel (a) and E/e’, n=43, panel (b)) of patients with heart failure with preserved ejection fraction (HFpEF). E/A values were determined in HFpEF patients without atrial fibrillation. E/e’ values were determined in patients with sufficient acoustic window for accurate echocardiographic measurement. The threshold for correlation was defined as r²>0.1 and p<0.05.
