To assess the frequency of persisting symptoms after SARS-CoV-2 infection and assessment of the effects of COVID-19 pandemic on selected parameters of self-reported health status and well-being half a year after the disease. The study population consisted of 3 groups: post-COVID-19 group I—172 patients; group II—172 patients with chronic disease, who have not suffered from COVID-19; group III—81 patients from a population study cohort—Bialystok PLUS. A standardized interview questionnaire was used to collect data in the three groups using the CATI (computer assisted telephone interviewing) technique. Interviews were conducted between October 2020 and January 2021, thus during the second wave of the pandemic in Poland. The subjective state of health in comparison with the state of health before the COVID-19 pandemic deteriorated in COVID-19 convalescents. Patients, who suffered from symptomatic COVID-19 were more prone to nervousness, anxiousness, tension than patients with oligosymptomatic course of the disease. Moreover, anxiety, fear and irritability were more frequent in Group I and II in comparison to Group III, whereas Group I and II did not differ significantly. The decrease in physical activity observed in COVID-19 patients mirrored the changes in general population. The most frequent persistent symptoms after COVID-19 are: general malaise, cough, smell and taste disorder, dyspnea. COVID-19 convalescents who experienced symptomatic disease are more prone to development of nervousness, anxiousness, tension and anxiety than patients with oligosymptomatic course of the disease. Females and younger patients who suffered from COVID-19 are more prone to development of mental distress than healthy population. No significant differences between COVID-19 convalescents and healthy population was observed as far as the attitude towards physical activity is concerned.

The outbreak of the COVID-19 pandemic caused the healthcare system to drastically reduce in-person visits and suddenly switch to telemedicine services to provide clinical care to patients. The implementation of teleconsultation in medical facilities was a novelty for most Polish patients. In Poland, the main telehealth services were provided in the form of telephone consultations. The aim of this study is to determine patients’ perceptions of telemedicine in the context of their experiences with the healthcare system during the COVID-19 pandemic. In this study, we presented how the evaluation of telemedicine services from the perspective of patients in Poland changed in the context of the ongoing pandemic. We conducted two surveys (year by year) on a representative quota sample of the Polish population (N = 623). This ensured that our observations took into account the evolution of views on telemedicine over time. We confirmed the well-known relationship that innovations introduced in the healthcare sector require a longer period of adaptation. We also identified significant concerns that limit the positive perception of telemedicine and compared them with experiences described in other countries.

The COVID-19 pandemic shook up societies, leaving a stigma on the health and well-being of many individuals. How big this stigma was depended on individual factors, which researchers are now trying to relate. One aspect affecting well-being during the pandemic may have been religiosity. In our longitudinal study of a representative sample of Poles, we took two measurements, in March 2021 and April 2022, obtaining a sample of N=622 repeated respondents out of 1000. We categorized participating individuals as religious, fuzzy or secular and, partly using retrospective questions, we compared their levels of well-being (WHO-5 index, Q-LES-Q-SF) before the outbreak as well as one and two years after the outbreak of the COVID-19 pandemic. We found that in the general population, despite a decline in well-being one year after the pandemic outbreak (2021), there was an improvement in the following year (2022), with religiosity proving to have a positive impact on well-being. The religious category achieved higher well-being values than the secular, especially in March 2021, when the effects of the pandemic were strongly felt in society in the form of lockdowns and the highest number of deaths.

Background The exploration for the impact of surviving a coronavirus disease of 2019 (COVID-19) on the cardiovascular system and cause-and-effect relationships is still a challenge for researchers. Purpose The aim of the study was to evaluate the parameters of right and left atrial deformation using strain imaging in echocardiography (ECHO) among undergoing COVID-19, their relationship to the survival of this disease, and to investigate whether there is a relationship between these parameters and laboratory, anthropometric and echocardiographic markers. Methods The study consisted of 134 patients of the study group - subjects examined 6-9 months after hospitalisation due to COVID-19 infection, and 134 control subjects - participants of the Bialystok PLUS project, examined before the pandemic (the assumed start date of the pandemic in Poland is 18 March 2020). The groups were matched for age and gender. In all subjects, an extensive medical history was taken, anthropometric measurements, a comprehensive panel of laboratory tests, blood pressure, pulse wave velocity (PWV) were measured. ECHO was performed including assessment of right (RA) and left atrial (LA) strain parameters. Results Individuals after COVID-19 had significantly lower RA strain parameters, such as: global longitudinal strain (40.5±13.8% vs. control group 47.2±13.4%, p<0.000) and global circumferential strain (26.9±16.5% vs. 32.8±16.5%, p=0.014), while no differences were found for LA strain. Significantly lower values of parameters characterising LV diastolic function, i.e. E/A (p=0.003) and septal e' velocity (p=0.012), were also observed in COVID survivors. Troponin (hs-TnT) (p<0.000) and CRP protein (hs-CRP) (p=0.011) levels were significantly higher in the survivors group, while total cholesterol (p=0.001) and LDL fractions (p<0.000) were significantly lower. Subjects after COVID-19 also had significantly higher neck, waist, hip circumferences (p=0.013; p=0.045, p=0.001 respectively) and body mass index (BMI) (p=0.045). The groups did not differ in metabolic markers (fasting glucose, glycated haemoglobin, HOMA-IR index). A multivariate linear regression analysis was conducted to assess which parameters might be related to the RA strain parameters. The results were shown in the table 1. Conclusions COVID-19 infection results in worsening of right atrial strain parameters. This phenomenon requires deeper analysis.

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<0.001). In the group during COVID-19 the dimensions of all cardiac chambers, i.e., left atrial dimension (p<0.001), left atrial volume index (LAVI) (p<0.001), right atrial volume (p<0.001), left ventricular dimension (p=0.013), right ventricular dimension (p=0.046) and aortic root dimension (p=0.001) were larger compared to the pre-pandemic population. The ECG showed longer P-wave (p=0.022), PQ segment (<0.001) and QRS complex durations (p=0.042) in the pandemic population compared to the pre-pandemic population. In contrast, there was no significant statistical difference between the analyzed groups in terms of left ventricular hypertrophy (LVH) assessed by ECHO or ECG criteria. In addition, N-terminal pro-brain natriuretic peptide (NT-proBNP) concentrations was significantly higher in the population during COVID-19 (p=0.011). Conclusion SARS-CoV-2 has had an impact on the cardiovascular system by increasing the size of all heart chambers and the root of the aorta which may have deleterious effects in the future. Careful monitoring of long-term effects is needed.
