Clinical narrative: Heart attack / she had a MI / diagnosed as a NSTEMI; This is a spontaneous report from a contactable healthcare professional (patient). This 52-year-old female patient received the first single dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE) in left arm, on 07Jan2021, for COVID-19 vaccination. Medical history included autoimmune thyroiditis (Hashimoto's thyroiditis) from 1998 and vitiligo from 1988. She was overweight. She had really no other risk factors. Concomitant medications were not reported. On 08Jan2021 the patient experienced heart attack and she had a MI, then a cardiac catherization that was normal and a normal echo as well. She said it was diagnosed as a NSTEMI and not a large MI, the smaller version. These events required hospitalization from 08Jan2021 to 12Jan2021. MI occurred after she finished clinic and she was not standing or doing anything, just sitting and she had chest pain. Her office was right next to the ER, so she received treatment within an hour and they were able to help her. She said that her hospital couldn't do a cardiac cath, so on 11Jan2021 they moved her to an hospital which was another treatment facility. When she had her MI they gave her acetylsalicylic acid (ASPIRIN) and sublingual nitroglycerin. They tested her troponin and did an EKG which was abnormal on an unspecified date in Jan2021. On 08Jan2021 troponin was increased. When they treated her with nitroglycerin and Aspirin, two hours later her EKG was normal and her troponin came down overnight on 09Jan2021, which was when they said for sure that she had a heart attack. The patient said it was very scary to have a heart attack, but thankfully there was not a lot of damage done and she was able to get treatment quickly. She did not think the event was disabling since they did not see much damage to her heart muscle, it was a near miss kind of thing. She said it was life changing in that she will now be on medication forever, she will be on at least a baby Aspirin and probably something like a statin for the rest of her life. She was recovering, it was unknown what the lasting effects may be, she felt normal but tired from her hospital stay. Heart attack resolved on 08Jan2021.  Information on the lot/batch number has been requested.; Sender's Comments: Based on temporal association, the causal relationship between BNT162B2 and the event acute myocardial infarction cannot be excluded. The contributory role of the patient age and background of obesity cannot be excluded as well.
