Therapeutic measures were taken as a result of cardiac failure, myocardial injury. Clinical course: When asked about her concomitant medications, patient mentioned that she doesn't change her medications. Since turning 60-years-old, she was reacting to changes in her drugs. The patient worked in nursing in mental hospitals. She was a technician and never was a Registered Nurse or Licensed Vocational Nurse. The patient used to be 5ft 6in but she lost 3 discs and it was estimated she lost an inch in height. This was prior to the COVID-19 vaccine booster. It was a work injury that took her off work. The patient mentioned she has had a hard time finding anyone to listen to her. It's understandable of people being afraid of the shot. She's at the "end of her life" and has heart damage. The patient stated she had a very grave reaction to COVID-19 vaccine booster shot. On an attempt to clarify with patient what she meant by "grave reaction", she stated she has heart damage. She got the booster shot the second week in Jul2022 and was given at her apartment because she is wheelchair bound. Got the booster shot because she was due for the booster and thought it was the Moderna. She was hesitant, but let the nurse give her the Pfizer COVID-19 Vaccine booster. Two hours after booster, she was in the emergency room. States Pfizer can get ahold of the hospital for that information. At this time, they didn't talk to her about the heart damage. The patient's mother wouldn't let any of her kids take shots so patient is still endangered to smallpox. Her doctor explained how dangerous it was to not have shots so patient had all she could get. When she was brought in on the stretcher, the nurse put an IV in her, did her blood pressure and asked if patient had a rapid heart rate. Patient never had a rapid heart rate, but her heart rate was 119 beats per minute. She was sent home and knew it was wrong. She was not admitted to the hospital. Sent home, she was just very weak, could hardly pick up her feet. Subsequently, it just really confused her. She was so weak and couldn't do anything. She was going without a home health worker. With someone like her, she qualifies for 200 hours of a home health worker but can't find people that will work. She was trying to get through the door on the laundry room in her apartment. Was fighting with this door because she was too utterly weak to hold the door and pull her laundry wagon. She then broke a bone in her leg and ended up in the hospital again. This time, she got a really rapid heartbeat. This was Nov2022. Then clarifies she broke a bone in her ankle not her leg.  Stated it's hard to remember when as she gets old. It's such a mess and she can't read her own writing. States maybe it was Oct2022 when she broke her ankle. Patient then corrects herself again stating she did not break her ankle, she broke her tibia, 8in above her ankle.  She was not admitted to the hospital after breaking her tibia. She was sent home. Knew she was going to die if she didn't do something because she was getting weaker and weaker. Patient called physician who couldn't see her for a week but scheduled her for an appointment with a cardiologist for 10Jan2023. She let it go for a day but then thought she is going to die if she doesn't get to someone about her heart not working. She called physician office and said she has to be seen. The physician did an EKG and sent her to the hospital. A bunch of tests were done, but patient was unsure if she was admitted to the hospital or if she was sent home. By this time, she was really sick. She missed an appointment but doesn't specify which appointment. She is confused about this and the dates. States she was admitted to the hospital on 25Nov2022. She was trying to deal with heart failure and a broken bone in leg. She thinks she was admitted to the hospital on 18Nov2022 to 25Nov2022 and has been out since. She was just very weak, could hardly pick up her feet/she was getting weaker and weaker. She was diagnosed with heart failure. Had so much happen to her, her brain can hardly take it in. She has had a total of 5 COVID-19 Vaccines, doses 1-4 are all manufactured by Moderna and dose 5 was manufactured by Pfizer. Reiterates her Pfizer COVID-19 Vaccine booster shot was in Jul2022, but she cannot provide the exact date. Then clarifies on her vaccination record card, this dose was given on 11Oct2022, not Jul2022. Reiterates she reacted two hours after receiving the Pfizer booster shot and was in the emergency room. It was very devastating; she was having so much trouble with her breathing. The patient wants to be sure the government or someone is making an effort to respond to people who are fearful of the shots. If she had young kids who knew someone like a reaction she had, she wouldn't let them get the shots.
