Abstract
Background Evidence of diastolic dysfunction (DD) required for the diagnosis of heart failure with preserved ejection fraction (HFpEF) is elusive in atrial fibrillation (AF). Left ventricular (LV) and left atrial (LA) speckle-tracking echocardiography (STE) may provide rhythm independent indications of DD. We aimed to find common LV/LA myocardial mechanics parameters to demonstrate DD, using STE in patients with AF. Methods 176 echocardiographic assessments of patients were studied retrospectively by STE. 109 patients with history of AF were divided in three groups: sinus with normal diastolic function (n = 32, ND), sinus with DD (n = 35, DD) and patients with AF during echocardiography (n = 42). These assessments were compared to 67 normal controls. Demographic, clinical, echocardiographic and myocardial mechanic characteristics were obtained. Results The patients with DD in sinus rhythm and patients with AF were similar in age, mostly women, and had cardiovascular risk factors as well as higher dyspnea prevalence compared to either controls or patients with ND. In the AF group, LV ejection fraction (LVEF) (p = 0.008), global longitudinal strain and LA emptying were lower (p < 0.001), whereas LA volumes were larger (p < 0.001) compared to the other groups. In a multivariable analysis of patients in sinus rhythm, LA minimal volume indexed to body surface area (Vmin-I) was found to be the single significant factor associated with DD (AUC 83%). In all study patients, Vmin-I correlated with dyspnea (AUC 80%) and pulmonary hypertension (AUC 90%). Conclusions Vmin-I may be used to identify DD and assist in the diagnosis of HFpEF in patients with AF.

Abstract
A wide range of ejection fraction (EF) thresholds have been used to categorize patients with heart failure (HF) with "preserved" EF. Our goal was to characterize the clinical and echocardiographic differences among patients with cardiac structural/functional alterations and mid-range EF (mrEF) (EF 40-49%) compared to preserved EF (pEF) (EF ≥ 50%), irrespective of HF. Patients with an EF ≥ 40% and echocardiographic evidence of structural alterations (left atrial enlargement and/or left ventricular hypertrophy) and/or functional alterations (evidence of diastolic dysfunction) were retrospectively selected. Patients with acute coronary syndromes and ≥ moderate left sided valvular diseases were excluded. Patients were divided according to EF to pEF group (n = 578) and mrEF (n = 86). Patients with mrEF were twice as likely to be men, had higher prevalence of hyperlipidemia, diabetes and smoking, compared to patients with pEF. History of coronary artery disease (CAD) was more frequent among mrEF (50% vs. 28%, p < 0.0001, respectively), and highest among the subgroup of patients with HF (83% vs. 35%, p < 0.0001, respectively). Patients with mrEF had increased LV mass index (131 ± 35 vs. 120 ± 26 g/m2, p < 0.001), LV end diastolic diameter (55 ± 5 vs 51 ± 3, p < 0.0001), mitral E to e' ratio (16 ± 7 vs. 14 ± 5, p = 0.001), and left atrial systolic diameter (44 ± 5 mm vs. 42 ± 4 mm, p = 0.01. respectively). Patients with mrEF demonstrated worse structural and functional echocardiographic alterations and were more likely to be men and to have CAD compared to patients with pEF.

Abstract
BACKGROUND Diastolic dysfunction (DDFx) is the major underlying mechanism of heart failure with preserved left ventricular ejection fraction (EF). Yet, the echocardiographic diagnosis of DDFx in patients in sinus rhythm is challenging and up to 25% of studies have discrepant measures making assessment of DDFx indeterminate. We aimed to describe the clinical and echocardiographic characteristics of patients with indeterminate diastolic function compared to patients with definite normal and abnormal diastolic function. METHODS One thousand six hundred seventy-four patients were identified from the echocardiography database in sinus rhythm, EF ≥ 45% without wall-motion abnormalities, valvular, congenital heart diseases, cardiomyopathies or pulmonary disease. Patients were divided according to their lateral mitral E/E' ratio and left atrial systolic diameter: normal diastolic function (DFx) (left atrial systolic diameter [LASd] <40 mm, E/E' < 10), DDFx (LASd ≥ 40 mm, E/E' ≥ 10) and indeterminate DFx (discrepant LASd diameter and E/E' ratio). RESULTS Clinical and echocardiographic characteristics of the 3 groups, DDFx (n = 186), indeterminate diastolic function (IndtDFx) (n = 207), and normal diastolic function (NDFx) (n = 1281) were significantly different. IndtDFx demonstrated intermediate parameter abnormalities, largely overlapping with DDFx. LASd and E/E' were similarly associated with the inability to determine diastolic function. Age, female gender, renal failure, E/E' and pulmonary pressure were found to be independent predictors of heart failure symptoms (RR = 1.02, 1.5, 2.5, 1.1, 1.1, respectively, P < .0001, r = .35). CONCLUSION Clinically and echocardiographically patients with IndtDFx are more closely related to DDfx than to NDFx. Although LAd was abnormal in IndtDFx it was not predictive of heart failure symptoms. Further study is suggested to establish whether LA function rather than its maximal size can provide additional information.
