Clinical Profile of Post-COVID-19 Patients with Persistent Chest Pain: A Cross-sectional Study

Introduction: Chest pain in post-COVID-19 patients can be due to serious alarming post-COVID-19 sequelae, such as Coronary Artery Disease (CAD), pulmonary embolism, myocarditis, etc. Approximately one-fifth of patients attending clinical Outpatient Department (OPD) following COVID-19 recovery present with persistent chest pain. There is limited knowledge about the clinical profile of patients experiencing persistent post-COVID19 chest pain. Aim: To describe the clinical profile of such patients to fill the knowledge gap and acquire new insights into patients with post-COVID-19 persistent chest pain. Materials and Methods: A cross-sectional study was conducted, enrolling a total of 259 patients with persistent chest pain (i.e., chest pain lasting more than 24 weeks after COVID-19 diagnosis). After detailed history-taking and clinical and laboratory examinations, observed data were collected, compiled, evaluated, and analysed to achieve the study objectives. Results: Out of 259 patients, 133 (51.4%) had cardiac {85 (32.8%)} or pulmonary {48 (18.5%)} abnormalities. Among patients with cardiac abnormalities, CAD, arrhythmia, myocarditis/cardiomyopathy, pericarditis, and PAH were detected in 38 (14.6%), 18 (6.9%), 7 (2.7%), 11 (4.2%), and 11 (4.2%), respectively. Meanwhile, among patients with pulmonary abnormalities, 36 (13.9%) patients had organic residual lesions in the lung parenchyma, 7 (2.7%) had pleuritis, and 28 (10.8%) had pulmonary function abnormalities. The remaining 126 (48.6%) patients experienced chest pain due to non cardiopulmonary aetiologies like gastrointestinal {45 (17.3%)}, musculoskeletal {38 (14.6%)}, psychomotor {35 (13.5%)}, autonomic {8 (3.3%)}, etc. Conclusion: This study found that chest pain in post-COVID-19 patients arises due to multisystemic aetiologies such as cardiac, pulmonary, visceral, autonomic, psychomotor, musculoskeletal, etc. A wide spectrum of serious cardiac abnormalities (such as CAD, arrhythmia, myocarditis, pericarditis, PAH, etc.) contributes to about 1/3rd of cases of persistent chest pain in post-COVID-19 patients.
