Description

This is a spontaneous case received from a contactable physician (patient). A male patient of an unspecified age received his second dose intramuscularly at site of arm at 08:30 on 19Jan2021 at single dose for COVID-19 immunization. Medical history included ongoing heart failure, ongoing hypertrophic cardiomyopathy, COVID-19. Concomitant medication included ongoing sacubitril valsartan sodium hydrate (ENTRESTO), ongoing furosemide (FURON), ongoing spironolactone (VEROSPIRON). The patient previously received his first dose of COMIRNATY on 29Dec2020 for COVID-19 immunization and experienced tiredness (lasting for about 4 hours) and pain in arm lasting for two days occurred at the same day. Both tiredness and pain in arm subsided. Due to heart failure he undergone Holter monitoring repeatedly, at the time of the vaccination he had it for 2 weeks already (he was supposed to have it for three weeks in total). Around half past eight he received the vaccination and around half past eleven he started to be tired, weak, wheezy, with hypotension (blood pressure 90/50), heart rate around 100, he had difficulties with breathing, he was hypoxic. All of this subsided, he as well experienced vertigo (probably connected to hypotension). At home he suffered from strong dyspnea for 4 hours. After 4 hours it all spontaneously subsided. At night he experienced a flu-like feeling, muscle pain, weakness, but it went away and the next day he went to work as usually. Hypoxic reaction activated myocardium, on Thursday on 21Jan2021, he collapsed, lost his consciousness, was transferred to the emergency department, from where he was transferred to cardiology intensive care unit where he undergone a surgery. Based on the Holter monitoring results it was discovered, that he suffered from atrial flutter (due to which he collapsed) and ended up with catheter ablation to adjust the heart rhythm. At hospital he was told, that it could be caused by a reaction to the vaccination, which caused the hypoxia, which led to the myocardial reaction. It was a very serious reaction, patient could have died. In the hospital he had borderline levels of COVID antibodies, after the repeated teste he was negative, which can support the statement that it was COVID-related. The outcome of events collapse circulatory, atrial flutter, flu-like symptoms, lost consciousness and muscle pain was recovered in Jan2021. The outcome of events tiredness, wheezy, hypotension, difficulty breathing, hypoxia was recovered on 19Jan2021. The outcome of event weakness generalized was recovered on 20Jan2021.; Sender's Comments: A possible contributory effect of suspect on reported events cannot be excluded.
