Context: The epidemic of heart failure (HF) in France has not been fully investigated and data on both the systolic and diastolic forms are limited.
Objectives: To determine the prevalence, aetiology and treatments of both forms in French patients over 65 with HF (NYHA grade II-IV).
Participants: Cross-sectional study of 446 patients with HF recruited by 273 randomly selected cardiologists in France, with echocardiography and ECG available for central reading.
Main Measurements: Prevalence of diastolic (DHF) and systolic (SHF) HF using the left ventricular ejection fraction (LVEF).
Results: DHF, with a mean LVEF of 57.6+/-8.0%, was reported for 245 (54.9%) patients and SHF, with a mean LVEF of 33.33+/-8.0% was reported for 201 (45.1%) patients. Men were more prone to suffer SHF than DHF whereas for women the reverse was true. As compared to SHF, DHF endsystolic and enddiastolic volumes were smaller, the thickness/radius ratio was greater, with a longer E-wave deceleration time and a shorter peak filling rate. Aetiology and treatments were similar in both types of HF, except for ACE inhibitors and aldosterone antagonists, which were more frequently prescribed in SHF.
Conclusion: This observational study provides further knowledge of SHF and DHF in outpatients.

This study investigates the effect of sacubitril/valsartan (Sac/Val) in patients diagnosed with nonvalvular atrial fibrillation (AF) without systolic heart failure (SHF).Nonvalvular AF patients without SHF admitted to the People's Hospital of Bortala Mongol Autonomous Prefecture from December 2020 to December 2021 were enrolled and randomly divided into Sac/Val treatment group (group T) and valsartan treatment group (group C, control). For subgroup analysis, patients were divided into subgroups with and without diastolic heart failure (DHF).

Background: We sought to evaluate respiratory complications in heart failure patients undergoing left atrial appendage occlusion (LAAO) for stroke prevention in atrial fibrillation.
Methods: Adult admissions (>18 years) undergoing LAAO during 2016-2020 were identified from the National Inpatient Sample. Heart failure (HF) was stratified into systolic (SHF) and diastolic heart failure (DHF) and were compared to those without HF.

Heart failure (HF) is prevalent among patients with aortic stenosis and presents a poor prognosis. In order to better portray outcomes for HF patients undergoing transcatheter aortic valve replacement (TAVR), we evaluated clinical outcomes in patients with systolic vs diastolic heart failure who underwent TAVR in a large nationwide database. We searched the National Inpatient Sample (NIS) for hospitalized adult patients who underwent TAVR with coexisting history of systolic (SHF) or diastolic heart failure (DHF) as a secondary diagnosis using the ICD-10 codes.

Background And Aim: Heart failure in children differs substantially from the adult population. Clinical characteristics of pediatric diastolic heart failure has rarely been reported. In this study, we aimed to summary the causes, clinical features, lab tests, and treatment effect of pediatric diastolic heart failure.
