Long-term clinical and biochemical residue after COVID-19 recovery

Background The long-term health consequences of coronavirus disease 2019 (COVID-19) are still unclear. The majority of previous trials addressed the post-COVID-19 symptoms through comprehensive medical questionnaires for relatively short periods after recovery. We tried to detect the potential pathological clinical signs and biochemical residue which persist for more than 3 months after the negative real-time polymerase chain reaction (RT-PCR) test of SARS-CoV-2. Results Among 120 COVID-19 survivors of mean age 38.29 and 55.6% male proportion, systolic blood pressure was significantly elevated ( P =0.001). Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), D-dimer showed higher values in COVID-19 survivors ( P
