Write-up: I saw and evaluated the patient. I agree with the findings and the plan of care as documented in the Fellow note. Of note patient is a 17yo male with no significant past medical history who received the second dose of his Pfizer COVID19 vaccine on 5/25/21. This morning he woke up with chest pressure and eventually was seen at an outside hospital ED. EKG was concerning for possible myocarditis and he was transferred further work-up of myocarditis. On arrival, echocardiogram was performed demonstrating grossly normal LV function with some suggestion of apex hypokinesis. EKG was repeated and showed ST elevation in lead I and V1. Troponin was elevated at 1.11. On exam, no murmurs rubs or gallops. No known family history cardiomyopathy. I personally reviewed the echocardiogram. Overall, patient is a 17yo male with what appears to be myocarditis that is temporally associated with the second dose of the MRNA Pfizer COVID19 vaccine. We have seen several of these patients with similar presentations over the past few weeks and most seem to respond well to treatment with IVIG and steroids. We will confer with our Rheumatology and ID colleagues. Plan will be to obtain cardiac MRI in the next 24 hrs. Ibuprofen PRN for pain. Will trend troponin and EKG.

CDC Split Type:

Write-up: Patient received 1st dose Pfizer COVID vaccine at a store/pharmacy on 5/25/21. Presented to ED with chest pain on 5/28. Diagnosed with myocarditis and admitted to the hospital. ED attending note: Patient presents with acute onset of chest discomfort in the sternal area 2 days after the first dose of Covid vaccine. Patient''s not had any fevers. No respiratory symptoms. No difficulty with respirations or any pleuritic chest pain. Denies any cough. No chest wall trauma. No back pain. No palpitations or syncope. No orthostasis. No peripheral edema. On physical exam he was mildly tachycardic in the 80s to low 90s with no murmur and no gallop. No JVD. Clear lungs. No rub. Bedside ultrasound performed by HCP had bilateral lung sliding and normal gross function based on 2 views. No pericardial effusion. EKG had ST changes. Chest x-ray was obtained without any effusions or pulmonary infiltrates. Normal cardiac silhouette. Troponin sent elevated. Cardiology consulted for possible postvaccination myocarditis. Child remained stable. Resting heart rates in the 70s and low 80s. Cardiology came to see the patient. Plan to admit to cardiology service. Presumed diagnosis of myocarditis. Cardiology admitting note: Pt. is an otherwise healthy 14yM who presents with acute onset atraumatic chest pain i/s/o recent covid vaccine, found to have mildly elevated inflammatory markers and troponin with borderline ST changes on EKG most consistent with mild peri/myocarditis at this time given overall well appearance on exam without hemodynamic or respiratory compromise and grossly normal function on POCUS, though plan for formal echo in AM. EKG w/ non-specific ST-T wave changes in precordial leads, no evidence of strain or block. Admitted to the cardiology service for serial troponins, ECHO, and close monitoring. HPI per cardiology consult note: "Patient is a healthy 14 year old with a history of alopecia who presented to the ED with mild chest pain 4 days following his first Covid vaccine (Pfizer). He had no symptoms in the days immediately following vaccine, and played basketball the day following with no symptoms, but after waking up today began having dull mid sternal chest pain. It was a 4/10, worse with lying down, non pleuritic, not sharp, and not radiating pain and not associated with any other symptoms including SOB, numbness, GI pain, cough, or anything else. Has not taken any meds for the pain. Has not exercised today. Felt "warm" this AM, but didn''t check temperature and felt better throughout the day. No palpitations, dizziness. Denies ever having chest pain before and no recent illnesses or sick contacts. No notable fhx of cardiac disease. In the ED, troponin mildly elevated to 0.12 ng/mL and CRP 5 with low ESR and BNP. Bedside point-of-care US reportedly showed no clear effusion with grossly normal function. HR mainly in 70s in ED and normotensive. EKG with borderline nonspecific ST elevation in V3-V6."
