Abstract

Abstract: Funding Acknowledgements: Type of funding sources: None. Background: Vaccination against Covid-19 has been proved an effective protective measure against the pandemic. It has been noticed that a number of patients visited the emergency department (ED) complaining of chest pain following their vaccination. Purpose: To record the patients that visited the ED of our hospital referring chest pain following their vaccination with BNT162b2 vaccine, the clinical and laboratory parameters as well as their final diagnosis. Methods: We recorded the patients that visited the ED of our hospital (secondary hospital) referring "chest pain after the vaccine", for a period of 6 months. We included patients that had received the first or the second dose of the vaccine 1-30 days prior their visit. We recorded basic demographic characteristics, ECG findings the laboratory test results as well as the possible diagnosis made in the ED. Results: 207 patients visited the ED complaining of "chest pain after having the Covid-19 vaccine", 96 male and 111 female, with mean age 47±8.2 years. 7 patients(3.38%) had elevated high sensitivity troponin and were diagnosed with myocarditis ( 2 female patients aged 5 and 62 years and 5 males aged 18-24 years. In 5/7 ST elevations were recorded in the 12-lead ECG, in 4/7 the transthoracic echocardiogram(TTE) revealed mildly impaired left ventricular function. Myocarditis was confirmed via cardiac MRI in all patients. Virology tests were negative for the common viruses.6/7 visited the ED 2-5 days after the second dose, whereas 1/7 10 days after the first dose). 2 patients(0.96%) were diagnosed with pericarditis (Both of them had received the second dose 5-7 days prior their visit, presented with pericardial rub and diffuse ST elevations in the ECG, as well as elevated CRP and moderate pericardial effusion). For the remaining 198 patients (95.65%) we did not record any abnormal findings in the ECG or the chest X ray and the chest pain was regarded non cardiac. Interestingly enough, 107 patients (51.69%) found to have a mild to moderate increase in the D-Dimer levels (mean 1.1±0.6 mg/l).Pulmonary embolism and aortic dissection was excluded to all of them based on our hospital's protocol. Conclusion: The vast majority (95.65%) of patients complaining of post Covid-19 vaccine chest pain had normal ECG and laboratory findings, suggesting a non cardiac origin.There were diagnosed some cases with myocarditis or pericarditis, a well described possible side effect of the BNT162b2 vaccine. Moreover, 51.69% of these patients were found to have elevated D-Dimer levels but we did not record any clinical significance.
