Cardiovascular sequelae of hyperthyroidism: A rare case report of thyrotoxic cardiomyopathy

INTRODUCTION: This case report highlights a distinctive presentation of cardiovascular sequelae arising from hyperthyroidism, shedding light on a rarely observed condition within the medical literature. The unique aspects of this case contribute valuable insights to our understanding of the intricate relationship between thyroid dysfunction and cardiac complications. CLINICAL PRESENTATION: The patient exhibited a constellation of symptoms, including palpitations, weight loss, and anxiety, indicative of hyperthyroidism. Notably, a thorough clinical examination revealed critical cardiovascular findings, such as elevated heart rate, arrhythmias, and signs of heart failure, underscoring the significant cardiac implications associated with this disorder. DIAGNOSIS AND INTERVENTIONS: Following a comprehensive diagnostic process, the patient was diagnosed with thyrotoxic cardiomyopathy, a rare manifestation of hyperthyroidism characterized by cardiac muscle dysfunction. Therapeutic interventions encompassed a multidisciplinary approach involving antithyroid medications, beta-blockers, and supportive heart failure management. The intricate connection between thyroid function and cardiac performance necessitated tailored treatment strategies. OUTCOMES: A notable improvement in the patient’s clinical status was observed throughout treatment. Reduction in heart rate, resolution of arrhythmias, and amelioration of heart failure symptoms collectively underscored the efficacy of the chosen interventions. This case report emphasizes the importance of prompt and accurate diagnosis and a comprehensive treatment regimen in achieving positive clinical outcomes in patients with thyrotoxic cardiomyopathy. CONCLUSION: This case is a poignant reminder of the interplay between endocrine and cardiovascular systems. The unique presentation of thyrotoxic cardiomyopathy in the context of hyperthyroidism expands our knowledge of potential cardiovascular sequelae. Clinicians are urged to consider such intricate connections and remain vigilant for atypical cardiac manifestations in patients with thyroid dysfunction. Timely intervention and tailored management strategies are paramount in mitigating the impact of these rare yet clinically significant conditions.
