Brief Summary

This study is a prospective, randomized controlled, basket trial. Patients diagnosed with Post-Acute Sequelae of SARS-CoV-2 Infection who meet the inclusion and exclusion criteria are recruited and divided into three symptom clusters: Inflammatory Cardiac involvement symptoms cluster, cough symptoms cluster and fatigue symptoms cluster. Each symptom cluster is randomly divided into an experimental group and a control group, Patients who do not accept treatment can be included in the observational cohort. Subjects in the experimental group receive immunomodulatory interventions plus conventional treatment, while subjects in the control group receive conventional treatment only. Subjects in each symptom cluster undergo clinical medical record data collection, laboratory tests, and imaging examinations at specified time points, as well as records of adverse events.
