Background The long-term complications in the cardiovascular (CV) system that the acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may cause are not fully understood. The aim of the study was to assess the impact of a coronavirus disease of 2019 (COVID-19) pandemic on echocardiographic (ECHO) and electrocardiographic (ECG) parameters. Methods This was single-center prospective cohort study. The study population consisted of 2 groups: the group before the COVID-19 pandemic (713 probands tested from 18. March 2018 to 17. March 2020) compared to the group during the COVID-19 pandemic (425 probands tested from 14. July 2020 to 02. March 2022). The comprehensive assessment was performed including laboratory parameters, ECHO and ECG. Results The studied populations did not differ by sex, age, body mass index and systolic blood pressure (BPs), while diastolic BP (BPd) was significantly lower in the group during the COVID-19 pandemic (p
