Patient's wife said that nothing like this has happened in the past. The patient was sitting at the kitchen table at about 5:30 pm and it was about an hour since they ate. The patient all of the sudden didn't feel right, couldn't breathe, was having chest pains, and was white as a ghost, started sweating profusely. The reporter and the patient got in the car and went to the hospital and they did a cardiac work up on him, they gave him nitro paste on his chest and was hospitalized or admitted because of the events. All the symptoms started at the same time. On 26Jun2021, they did an electrocardiogram/EKG which was fine (normal) but the patient's troponin was elevated. They transferred the patient to another hospital. The patient had a stress test on 27Jun2021, which was normal (They took pictures of the patient's heart during the stress test). Reportedly, the patient's blood pressure had never been high but it was high when he got to the hospital. The patient is not back to normal but was not complaining of anything. They put the patient on a heparin drip at the hospital for the troponin levels. The doctors are leaning more toward myocardiopathy and think it was related to the vaccine. The hospitalization duration was of 2 days, i.e., from 26Jun2021 to 27Jun2021. The patient was going to see a cardiologist on Tuesday. The outcome of the events: The doctors are leaning more toward myocardiopathy, blood pressure has never been high but it was high when he got to the hospital and troponin was elevated reported as unknown and the outcome was assessed as resolving for rest of the events.
