Myxedema Coma and the Heart: Would You Miss the Signs?

Myxedema Coma (MC) is a life-threatening medical emergency that occurs as a severe complication of untreated or poorly managed hypothyroidism. Prompt diagnosis is crucial as the condition can rapidly deteriorate and lead to life-threatening complications. Timely treatment of myxedema coma with intravenous levothyroxine is the cornerstone of treatment, along with glucocorticoids to support adrenal function. This condition is associated with cardiovascular manifestations that contribute to its high mortality rate. The heart in hypothyroidism typically shows reversible dysfunction that can be corrected with hormonal supplementation, and in some cases, requires inotropic and aminergic support. This case involves a patient who was admitted to the intensive care unit with suspected MC, and necessitated life-saving hormonal and cardiovascular support to manage the condition.
