they did a catheter which ruled out a heart attack & they said it was broken heart syndrome instead; didn't feel anything when they gave her the shot but that arm hurt real bad for 3 or 4 days; This spontaneous case was reported by a consumer and describes the occurrence of STRESS CARDIOMYOPATHY (they did a catheter which ruled out a heart attack & they said it was broken heart syndrome instead) in an 86-year-old female patient who received mRNA-1273 (Moderna COVID-19 Vaccine) (batch no. 002B21A) for COVID-19 vaccination. The occurrence of additional non-serious events is detailed below.     No Medical History information was reported.   On 27-Feb-2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On 27-Mar-2021, received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to 1 dosage form. In March 2021, the patient experienced VACCINATION SITE PAIN (didn't feel anything when they gave her the shot but that arm hurt real bad for 3 or 4 days). In April 2021, the patient experienced STRESS CARDIOMYOPATHY (they did a catheter which ruled out a heart attack & they said it was broken heart syndrome instead) (seriousness criterion medically significant). At the time of the report, STRESS CARDIOMYOPATHY (they did a catheter which ruled out a heart attack & they said it was broken heart syndrome instead) outcome was unknown and VACCINATION SITE PAIN (didn't feel anything when they gave her the shot but that arm hurt real bad for 3 or 4 days) had resolved.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): In April 2021, Angiocardiogram: inconclusive (Inconclusive) Inconclusive. In April 2021, Electrocardiogram: abnormal (abnormal) Suspected heart attack.     For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments.   No concomitant medications provided. The patient reported she had a heart problem 3 weeks after her 2nd shot. She felt bad all that day, then vomited all of a sudden, felt real weak, & had chest pains. They did an EKG & said it was a heart attack.  Then they did a catheter which ruled out a heart attack & they said it was broken heart syndrome instead.  She said it was not myocarditis or pericarditis. No treatment medications provided.  Company comment: This spontaneous case concerns a 86-year-old female patient with no medical history reported, who experienced the unexpected serious (medically significant) event of Stress cardiomyopathy after mRNA- 1273 vaccine. The event occurred approximately 3 weeks after the second dose of mRNA- 1273 vaccine. Clinical manifestations included chest pain, asthenia and vomiting. Electrocardiogram showed myocardial ischemic-like changes. However, coronary angiograph was normal, thus Stress cardiomyopathy was diagnosed. Laboratory results and echocardiogram were not reported. Very limited information is available regarding clinical course and treatment received. The benefit-risk relationship of mRNA- 1273 vaccine is not affected by this report.; Sender's Comments: This spontaneous case concerns a 86-year-old female patient with no medical history reported, who experienced the unexpected serious (medically significant) event of Stress cardiomyopathy after mRNA- 1273 vaccine.
