Preexisting Conditions:
Allergies: Mild Latex Allergy just a small rash if worn for long periods of time.
Diagnostic Lab Data: X-ray didn''t find and issues. The MRI determined that the cause was Myocarditis.
CDC Split Type:

Write-up: On Wednesday April 14th I got my second vaccination shot. The following day I had a 103 F fever, body aches, chills, migraine, sore muscles, couldn''t walk, excessive thirst. Those effects lasted all day and I felt better on Friday. Saturday night chest pain started along with sore arm getting worse. I took ibuprofen and melatonin to sleep. Woke up Sunday morning and pain came back and gradually got worse until I went into the ER around 9 am. They gave me Morphine to put the chest pain at bay. Then transferred me by ambulance to a different hospital with a cariology department. They treated me as if it was Myocarditis and also got an x-ray of my chest. The next morning I had an MRI and that is what confirmed it to be Myocarditis. I was then discharged with lots of medications to keep the inflammation down.

CDC Split Type:

Write-up: 1 day after the 2nd shot in the Pfizer COVID vaccine series he began to develop substernal pressure like chest pain . Patient was admitted into the hospital for 2 days (4/27-4/29) for this substernal chest pain. A CTPE, EKG, and CXR were ordered that were unrevealing as to the etiology of the chest pain. Troponins were elevated on admission with a slightly decreased delta (515-$g479). An ECHO was ordered that showed a LVEF of 35-40% with moderate global hypokinesis of the left ventricle, right ventricles moderately dilated, and no pericardial effusion. A Cardiac MRI was then ordered to determine etiology that showed subepicardial late gadolinium enhancement of the basal inferior and mid-inferior and inferoseptal wall consistent with acute myocarditis. Additionally, a small pericardial effusion without signs of inflammation, calcification, or cardiac tamponade physiology. Patient was then D/C on 4/29 after the cardiac MRI with no medical therapy with the recommendation to not partake in physical activity for one month. Will have follow up with cardiology clinic in 1 month and will participate in cardiac rehab.
