The COVID-19 pandemic has brought a series of challenges for cardiac patients, given their higher risk of severe illness. It was essential to provide continuous cardiac care with adherence to virus protection measures to safeguard the health of these patients along with proper categorization. The aim of the study was to compare hospitalizations of patients with chronic heart failure during the COVID-19 pandemic and the previous year (2019). Subjects and methods: The subjects were a group of patients regardless of gender and age with chronic heart failure who were hospitalized during the COVID-19 pandemic from 08.04.2020 to 08.06.2020 at the Rijeka Clinical Hospital Center at the Clinic for Heart and Blood Vessel Diseases, and patients with chronic heart failure who were hospitalized a year earlier in 2019 from 08.04.2019 to 08.06.2019 at the Rijeka Clinical Hospital Center at the Clinic for Heart and Blood Vessel Diseases. The frequency of admitted patients with chronic heart failure was analyzed along with data on the age and gender of patients and the condition upon admission, i.e., data on critical factors according to patient categorization. Results: There was no statistically significant difference between male and female patients during the pandemic. The same results were obtained for the average age of patients and days of hospitalization. Hyperlipoproteinemia was significantly more prevalent in patients admitted during the pandemic, as was the average number of patient comorbidities during the pandemic. Patient categorization during the pandemic was higher in category III than the expected II. Conclusion: It can be concluded that a statistically significant difference was found in the application of pharmacotherapy in the use of statins, there is a statistically significant difference in the patient's condition upon admission according to patient categorization: during the pandemic more patients were categorized in category III compared to the NYHA parameter and according to the NT-proBNP value, while there is no statistically significant difference in the outcome of patient hospitalization during the COVID-19 pandemic and patients a year earlier (2019).
