• W4315780072 abstract "Background: Hypertension is one of leading causes in heart failure with preserved ejection fraction (HFpEF).Left atrial (LA) maximal volume and index (LAVI) had a prognostic value in patients with heart failure and incidence of atrial fibrilation (AF). Recently, LA mechanical function and LA strain have been introduced as alternative methods to assess LA performance more accuratly. Aim: To evaluate the relation between early changes in LA function and strain (PALS) and correlate the association with global left ventricular (LV) function and longitudinal strain (GLS) in patients with HFpEF.and arterial hypertension. Methods: We evaluated 152 subjects in sinus rhythm: 22 normals (31y ± 5), and 70 pts with HFpEF (65y ± 12), 60 pts HFrEF (64 y ± 10). Echocardiography was performed in all patients and follow up after 12 monts and analyzed offline in order to extract the global and segmental strain values of the LV and LA and LA volume and LAVI. Results: The two groups of patients were comparable for most of clinical variables. LV volumes, ejection fraction, stroke volume, and mitral valve effective regurgitant orifice were similar between the two groups. The LA diameter and maximal volume were higher in HFrEF group. The GLS is significantly reduced in HFrEF group. LV GLS is the main parameter for myocardial dysfunction, which changed significantly in the HFrEF (p < 0,001) at 12mFU. Reduced PALS in HFrEF was associated with impairment of all measures of LV systolic and diastolic function and events of atrial fibrilation / 33 % in HFrEF and 12 % in HFpEF/ and the correlation between global longitudinal strain and PALS was highly significant (p < 0.001; r = 0.71). At 12mFU, PALS was significantly associated with lower global longitudinal strain in group with HFrEF (p < 0.001, r = 0.61), LAVI > 28 ml/m2 (p < 0.01,r = 0.57) and slightly decreased in HFpEF /p < 0.5, r = 0.34/. ROC analysis shows the cut of value of 29 % for PALS which correlated with AF events. Conclusions: PALS and GLS are significantly reduced in HFpEF patients and decreased in HFpEF. PALS provides additional,prognostic value beyond LA volume and LAVI. Severe LV myocardial dysfunction and reduced GLS and decreased PALS, even still normal LAVI is a prognostic index for AF." @default.
