The patient prolonged hospitalization for coronary artery dissection (start date: 07Mar2022). The patient underwent the following laboratory tests and procedures: Mammogram: Positive, notes: went to do a mammogram it came out that they thought something was wrong with my left breast. Therapeutic measures were taken as a result of coronary artery dissection, myocardial infarction. Clinical course:Patient stated, she wanted to report an issue with the Pfizer Vaccine (Clarified as Pfizer Covid-19 vaccine).She got the Pfizer, the initial one's in her left arm and then got the booster in her left arm. So, then when she went to do a mammogram it came out that they thought something was wrong with her left breast so she had to do like an invasive or non-invasive like extra check on her breast to make sure that she didn't have cancer or whatever. So then when she got the booster on the upper part of her shoulder like right below her shoulder and after that it occurred she had a strange pain on her left arm so, she was dealing with pain since she got that booster and the booster was valid April 20th or something of 2021 well then last in March she got admitted to the hospital and had a coronary artery dissection and is 45 years old so, she ended up like blood filled up her entire chest cavity and she almost died and to her all of this is effect of that Pfizer vaccine. When paraphrased the above concern she stated,It was her arm, she was dealing with that pain in her left arm for almost a year, it was a dozen months that she was having that pain in her left arm and it was extreme pain and then from March she felt like real heaviness in her chest, she got rushed to the heart hospital and they were like wanted her to sign off for her life and she had a coronary artery dissection, one of the valve was completely opened up and blood went down into her chest cavity and it dissected her heart. Now that she had that dissection, that pain in her left arm had finally gone away from Pfizer and she got Moderna (Unspecified vaccine) because they said that it was the higher protection if you got Pfizer and you got Moderna so she get Pfizer in her left she got the third booster, Moderna in my right and had no problems with it but everything on her left side since she had got the Pfizer Vaccine I got problems on left side of her upper body. So, she was dealing with pain and then on 07Mar she guess she was feeling from a while but on 07Mar her chest cavity completely filled and they thought she was having a heart attack but turned out it was dissection in her heart. Now she don't know what it is doing to women, she had problems with her left breast now and then she had problem with her left arm and then had a coronary artery dissection. She did not had any of these problems until she got the Pfizer vaccine.The Moderna she did on 05Jan2022 and that one was done at the (pharmacy name withheld) that one she did in her left arm, like your Pfizer she did all in her right sorry she did the Moderna in her right and both the Pfizer one on the left side of her arm. No, she got both of the Pfizer in the left and then when she got Moderna she did the right. Patient got hospitalized on 07Mar2022 and was discharged on March 9th or 10th.The reason why she had got so many vaccine is she has Lupus. So she have an auto immune disease. It was diagnosed Back in 2018 she think.She takes Methotrexate frequency once a week. There were side effects to the methotrexate. Then she take Tramadol that one she can take every 6 hours as needed because she can't take Ibuprofen, she can't take Prednisone; dosage 2mg.Patient stated she has Asthma and that one is Breo Ellipta. she is immunocompromised because of her Lupus. She is Bipolar and then also have Asthma or not Asthma but she had Pneumonia, double Pneumonia in her left lung so compromised that lung so for the Asthma or for whatever it is she takes Breo Ellipta.Now she is having to take medications for the heart problem too. so, she is on 4 new meds because of the dissection. It is the baby Aspirin it is 81 mg and it is a chewable table once in a day. Lipitor that one is 10 mg and that one's at bed time one tablet, orally. Plavix that one's 75 mg, it's a tablet and I take it once a day. Actually There is 2 more this one's brand name is withheld, that's 30 mg and she take that once in a day and then the last one for the heart is Nitroglycerine tablet brand name is withheld and that one is 0.4 mg and that one she take when she is starting to have chest pain and that one is sublingual, she put it under her tongue. These were all are from the 07Mar hospitalization.Patient has to go back to the heart hospital and they are going to have to re test her heart in 3 months to check and make sure that dissection is closed. They going to have to do echocardiogram on her and other thing.  The information on the batch/lot number for BNT162b2 has been requested and will be submitted if and when received.
