Abstract

Background: Dyspnea is the most common symptom associated with the COVID-19 caused by novel coronavirus SARS-CoV-2. The aim of this study was to assess the prevalence of dyspnea, observe co-variables, and find predictors of dyspnea after two months of recovery from COVID-19. Methods: This study was conducted in 327 patients and they were asked if they had experienced dyspnea with the COVID-19. Patients’ responses about dyspnea were categorized as being improved, remained the same, or (worsened) two months post-COVID-19. Software “R” was used in this study for statistical computing. The p-value was set <0.05 for all statistical tests. A repeated k-fold cross-validation was used for measuring the accuracy of logistic regression. Results: Of the total 327 participants in the study, 34% had stated that they were suffering from respiratory symptoms even after two months of COVID-19. The study demonstrated that SpO2 (p value <0.03), D-dimer (p value <0.001), serum ferritin (p value <0.006) and the presence of dyspnea are significantly correlated. The repeated k-fold cross-validation method revealed that the prediction performance was around 65%. Conclusion: These findings can be useful for the physicians treating COVID-19 patients after discharge from hospital.
