Purpose:Heart failure with preserved EF (HFpEF) is characterized by phenotypicheterogeneity. Loss of atrial function is of relevance in HFpEF, and interatrialdyssynchrony (IAD) appears to be one of its aspects. The prevalence of IAD hasnot been compared between patients with HF and various categories of LVEF.Methods:Data from 51 patients (24 HFpEF, 6 HFmrEF, 21 HFrEF) diagnosed with HFper current guidelines were analyzed retrospectively. IAD was measured from echoDoppler traces as the difference between the time of transmitral and transtricuspidA wave onsets.Results:IAD>60 ms was present in 8 HFpEF pts. (33.3%), 1 HFrEF (4.8%) and1 HFmrEF patient (16.7%) (p=0.039). Compared to pts. with LVEF<50%, thosewith HFpEF were older, had higher SBP, heart rate, LVEF, LVmass, smaller LVIDdand lower sPAP ; there was no difference in incidence of diabetes, NYHA class, NT-proBNP or eGFR , E/e’ or atrial volumes. Higher IAD was associated with a higherproportion of HFpEF, lower heart rate, and higher LVEF (Table 1).Conclusion:IAD is more prevalent in HFpEF compared to patients with LVEF<50%and does not appear associated with standard clinical parameters, NT-proBNP, LVmass, E/e′or atrial size.
