To describe a case of Takotsubo cardiomyopathy (TTS) potentially precipitated by hyperthyroidism following SARS-CoV-2 infection and to explore the interrelationship among these conditions.
Approach:
Case Presentation: A 21-year-old male presented with cardiac symptoms two weeks post SARS-CoV-2 infection, with ECG changes and echocardiographic abnormalities indicative of TTS.
Diagnostic Assessment: The patient underwent ECG, echocardiography, and biochemical tests confirming thyrotoxicosis, with coronary angiography ruling out myocardial infarction.
Treatment: The patient was treated with methimazole and beta-blockers, leading to resolution of cardiac dysfunction and normalization of thyroid function.
Key Findings:
The patient developed TTS concurrent with hyperthyroidism after COVID-19 infection.
SARS-CoV-2 may exacerbate autoimmune thyroid dysfunction and induce myocardial stress.
Thyroid evaluation may be warranted in COVID-19 patients presenting with cardiac symptoms.
Interpretation:
The case suggests a potential triad of viral infection, autoimmune thyroid disease, and cardiovascular vulnerability contributing to TTS.
Limitations:
The findings are based on a single case report, limiting generalizability.
The precise mechanisms linking COVID-19, hyperthyroidism, and TTS remain speculative.
Conclusion:
The interplay among COVID-19, hyperthyroidism, and TTS warrants further investigation in larger cohorts.
