Clinical narrative: From hospital discharge summary:  "45 y.o. right-hand-dominant male who presents with few hours of improving left arm heaviness/left hand cramping in the setting of getting his second Pfizer COVID-19 vaccination in his right arm 3 days ago and 3 weeks of mildly increased exercise/intermittent fasting. The patient reports getting his first Pfizer COVID-19 vaccination on April 7, 2021. Reports some mild symptoms afterwards. Around that same time, the patient reports having a checkup with his primary care doctor that was notable for a cholesterol elevation to 200. This prompted him to try and lose weight including intermittent fasting and increase in exercise, especially for exercises and cardio.  The patient reports approximately 20 pound weight loss over the past 3 weeks. 3 days ago, the patient reports getting his second Pfizer COVID-19 vaccination in his right arm.  Reports fever (maximum 103 Fahrenheit) and mild headache the subsequent 2 days after the vaccine.  Last night, the patient went to sleep on his left side at around 8 PM.  He woke up at 4 AM with significant left arm heaviness and left hand cramping.  He tried to massage his hand with some slight improvement of the symptoms but otherwise the symptoms persisted.  Hence, this morning, he called his PCP, who told him to come into the ER for further evaluation. Here, the patient reports improving left arm heaviness/left hand cramping.  He also does report family history of heart attack and an uncle at a similar age and massive heart attack of his grandfather in their 60s. He denies fever, anorexia, unexpected weight change, headache, blurry vision, sinus pressure, cough, hemoptysis, orthopnea, PND, SOB, DOE, chest pain, pleurisy, changes in taste/smell, N/V/D, abdominal pain, flank pain, urinary sxs, genital sxs, black stools, incontinence, absence of flatus, calf pain, leg swelling, numbness/tingling, streaking redness/rash/skin changes, easy bruising. Also, deny history of HTN, DM, smoking, prior MI, prior PCI, prior CABG, prior TIA/CVA, or history of PAD. Further, denies recent trauma/fall, history of cancer, blood thinner use, recent drug use, recent travel, sick contacts, family history of connective tissue disease/congenital aortic anomaly, or family history of similar sxs. --- Hospital Course by Problem  # Troponinemia (Likely myopericarditis)  The patient has a family history notable for MI and CABG in relatives aged 50-70 on his mother's side. The patient notes that most of these family members were heavy smokers and drinkers, which he is not (never-smoker, rare EtOH, never illicit drugs). His symptoms are notable for L arm heaviness/cramping that began around 8pm on 4/30/21 at 9/10 severity and subsequently was 3-4/10 severity on presentation to ED and is 0-1/10 severity at time of admission to the floor; he has no associated numbness, weakness, coolness, or pallor. His symptoms are non-exertional. He denies CP, SOB, lightheadedness, nausea, jaw pain, abdominal pain, fatigue. He noes that he recently got the second COVID shot in the R arm, and had a post-vaccine course notable for Tmax 103 ~3d ago and 101 as recently as yesterday. His EKG was notable for ST-elevation in II/III/aVF and his troponins were elevated 305 -- > 298 -- > 328. Of note, his CRP was elevated at 69. The patients symptoms and findings could certainly be compatible with atypical ACS and, given the low risk of bleeding associated with heparin, he was treated conservatively upon admission with heparin infusion, metoprolol tartrate 6.25mg q6h, atorvastatin 80mg (he received ASA 325mg in the ED). However, given his recent covid vaccination and elevated CRP and reported fevers, this could also be compatible with myocarditis or other inflammatory etiology.  TTE on 5/3 demonstrated preserved EF 55% with no WMA. Given reassuring TTE, a cMRI was ordered to assess for myocarditis vs scar tissue from recent ischemic event. Cardiac MRI on 5/5 was notable for finding consistent with myopericarditis (see below). Aspirin and atorvastatin was stopped on discharge. Patient was discharged with metoprolol 25 mg daily."
