The work aimed to evaluate the clinical, laboratory, and echocardiographic character- istics, and the treatment of patients hospitalized for heart failure (HF) at the Cardiology Clinic of University Hospital Nitra in the period from 1.7. until 30.9.2023. Method: A retrospective analysis of patients hospitalized due to HF at the Cardiology Clinic of University Hospital Nitra from July 1, 2023, to September 30, 2023. Results: The most frequent cause of hospitalization was a decompensation event of chronic HF (78%). The most common cause of HF was ischemic etiology (less than 40% of patients). In terms of comorbidities, the most common was arterial hypertension (AH) (97.6% of patients hospital- ized for HF had AH in the pre-disease). The heart failure phenotype with preserved ejection fraction (HFpEF) predominated (81 patients). The average EF was 44.67%. The most common valvular disease was severe tricuspid regurgitation in 51 patients (29%), followed by severe mitral regurgitation in 43 patients (24%). The mean entry NTproBNP value was 10,299 pg/ml. In total, RAAS inhibitors were included in the medication of 93% of patients. 92% of patients were treated with BB, 72% with SGLT2 inhibitors, 48% with MRA. ACEIs significantly shortened the time required for i.v. diuretic administration (p=0.008). Conclusion: From the retrospective analysis of the data of patients hospitalized for HF, patients with an ischemic cause and with a decompensatory HF event dominate. The most frequent comorbidity is AH, the HFpEF phenotype being the most frequent. We have documented a fair representation of basic groups of pharmaceuticals with confirmed prognostic significance.
