Background: Congestive heart failure (CHF) with reduced ejection fraction (HFrEF) or with preserved ejection fraction (HFpEF) is a common diagnosis in patients hospitalized in the department of internal medicine. Recently, the therapeutic regimens were updated, as the sodium-glucose cotransporter-2 (SGLT2) inhibitors became an integral part of the therapeutic regimen for either HFrEF or HFpEF.

Objectives: To define the demographic and clinical characteristics of CHF patients hospitalized in the department of medicine.

Methods: We conducted a retrospective cohort study that included all patients hospitalized in the departments of medicine at the Rabin Medical Center, Israel, between 2016 and 2019. Demographic and clinical background, in-hospital procedures, discharge regimens, and outcome parameters were evaluated according to HFrEF/HFpEF.

Results: The cohort included 4458 patients. The majority (97%) presented with a preexisting diagnosis, whereas HF was an active condition in only half of them. The rates of HFrEF/HFpEF were equal. In most cases, the trigger of the exacerbation could not be determined; however, infection was the most common cause. There were basic differences in the demography, clinical aspects, and therapeutic regimens at discharge between HFrEF and HFpEF. Both conditions were associated with high in hospital mortality (8%) and re-admissions rates (30 days [20%], 90 days [35%]) without any difference between them.

Conclusions: HFrEF/HFpEF patients differed by demographics and co-morbidities. They were equally represented among patients admitted to medical wards and had similar prognosis. For both diagnoses, hospitalization should be considered for updating therapeutic regimens, especially with SGLT2 inhibitors.

Background: The diagnosis of atrial fibrillation (AFIB) related cardiomyopathy relies on ruling out other causes for heart failure and on recovery of left ventricular (LV) function following return to sinus rhythm (SR). The pathophysiology underlying this pathology is multifactorial and not as completely known as the factors associated with functional recovery following the restoration of SR.

Objectives: To identify clinical and echocardiographic factors associated with LV systolic function improvement following electrical cardioversion (CV) or after catheter ablation in patients with reduced ejection fraction (EF) related to AFIB and normal LV function at baseline.

Methods: The study included patients with preserved EF at baseline while in SR whose LVEF had reduced while in AFIB and improved LVEF following CV. We compared patients who had improved LVEF to normal baseline to those who did not.

Results: Eighty-six patients with AFIB had evidence of reduced LV systolic function and improved EF following return to SR. Fifty-five (64%) returned their EF to baseline. Patients with a history of ischemic heart disease (IHD), worse LV function, and larger LV size during AFIB were less likely to return to normal LV function. Multivariant analysis revealed that younger patients with slower ventricular response, a history of IHD, larger LV size, and more significant deterioration of LVEF during AFIB were less likely to recover their EF to baseline values.

Conclusions: Patients with worse LV function and larger left ventricle during AFIB are less likely to return their baseline LV function following the restoration of sinus rhythm.
