Name of journal: SN comprehensive clinical medicineAbstract: Increased vaccination rates and better understanding of influenza virus infection and clinical presentation have improved the disease's overall prognosis. However, influenza can cause life-threatening complications such as cardiac tamponade, which has only been documented in case reports. We searched PubMed/Medline and SCOPUS and EMBASE through December 2021 and identified 25 case reports on echocardiographically confirmed cardiac tamponade in our review of influenza-associated cardiac tamponade. Demographics, clinical presentation, investigations, management, and outcomes were analyzed using descriptive statistics. Among 25 cases reports [19 adults (47.6 +/-15.12) and 6 pediatric (10.1 +/- 4.5)], 15 (60%) were females and 10 (40%) were male patients. From flu infection to the occurrence of cardiac tamponade, the average duration was 7+/-8.5 days. Fever (64%), weakness (40%), dyspnea (24%), cough (32%), and chest pain (32%) were the most prevalent symptoms. Hypertension, diabetes, and renal failure were most commonly encountered comorbidities. Sinus tachycardia (11 cases, 44%) and ST-segment elevation (7 cases, 28%) were the most common ECG findings. Fourteen cases (56%) reported complications, the most common being hypotension (24%), cardiac arrest (16%), and acute kidney injury (8%). Mechanical circulatory/respiratory support was required for 14 cases (56%), the most common being intubation (9 cases, 64%). Outcomes included recovery in 88% and death in 3 cases. With improving vaccination rates, pericardial tamponade remains an infrequently encountered complication following influenza virus infection. The complicated cases appear within the first week of diagnosis, of which nearly half suffer from concurrent complications including cardiac arrest or acute kidney injury. Majority of patients recovered with timely diagnoses and therapeutic interventions.
