About 100 adult patients hospitalized for HF in the Department of Cardiology will be included in the study, including: the study group with HFrEF, HFmrEF and HFpEF. Selected prognostic factors will be analyzed, among others: demographic data of the patient, physical examination, symptoms, etiology and history of HF, co-morbidities, results of selected laboratory tests, selected electrocardiographic and echocardiographic data, patient's cooperation with the doctor, treatment applied, parameters in the spiroergometric study and distance in 6MWT and subjective assessment of quality of life according to the KCCQ questionnaire. One year after inclusion in the study, a telephone interview will be conducted with patients. These will be questions about death, cardiovascular adverse events, hospitalization for heart failure and re-evaluation of the quality of life according to the KCCQ questionnaire.
The subject of the study is the factors of unfavorable prognosis in heart failure. We would like to identify independent variables associated with a bad prognosis of patients hospitalized for heart failure with a reduced vs. a mid range and preserved left ventricular ejection fraction based on specific predictive models. It is planned to create multifactorial models that can be used to predict prognosis for individual patients.
