Quality of Life of Chronic Heart Failure Patients During and After COVID-19: Observational Study Using EuroQoL-Visual Analogue Scales

Abstract

Background Chronic diseases affect both the mental and physical health of patients. An acute infection can further deteriorate it. The multi-organ damage and acute respiratory distress caused by coronavirus leads to worsening of the previously stable state of chronic diseases. Material/Methods The aim of our study was to compare the quality of life during pre-acute-post-COVID-19 infection status of chronic heart failure (CHF) patients based on responses on the EuroQoL-visual analogue scales (EQ VAS). Patients suffering from CHF and a COVID-19 infection were included in our study. EuroQoL questionnaires responses were recorded at 3 time-points (Q1 before COVID-19 infection, Q2 during an acute episode of COVID-19, and Q3 at 6 months after COVID infection). The statistical analysis was carried out both in a cross-sectional view for each time-point and longitudinally. The non-parametric Mann-Whitney test for independent series was applied in the case of subgroup comparison, and the Wilcoxon signed ranks test was used in the longitudinal study. Results Based on the responses given by the patients, there was decline in QoL noted in all patients, mainly in females, included in our study during the acute phase of the infection, as compared to their pre-COVID-19 admission for a follow-up for their heart disease (Q1: 78.89 vs Q2: 66.11 in males and Q1: 71.54 vs Q2: 49.6 in females, p=0.015 for Q2). Improvement was noted in the evaluation done after 6 months to the acute episode, although the values failed to attain to that of the initial pre-COVID-19 analysis, with Q3: 71.92 in males and 70.56 in females. Conclusions Understanding these implications can guide healthcare interventions for better management and support, particularly in the context of pre-existing chronic conditions exacerbated by acute infections like COVID-19. The results may prompt further research into the long-term effects of COVID-19 on individuals with chronic diseases, guiding future studies to explore specific interventions or preventive measures. QoL during the acute phase of COVID-19 infection is affected on a larger extent as compared to previous analysis in chronic heart failure patients. Larger studies with a longer time span can indicate the time duration required for CHF patients to attain the pre-COVID-19 QoL status. Developing methods to increase the accuracy of QoL evaluation can further reduce the bias witnessed, especially in previously unhealthy subjects. The study’s findings could inform healthcare providers about the heightened risk and specific challenges faced by chronic heart failure patients during and after a COVID-19 infection. Policymakers can use these findings to develop targeted public health policies aimed at protecting and supporting individuals with chronic conditions during and after infectious outbreaks, ensuring comprehensive healthcare strategies.
