Complications

Complications depend on the underlying NTI and other organ systems involved. A study by Rothberger et al, for example, suggested that in patients with acute heart failure, low T3 levels due to euthyroid sick syndrome may be a risk factor for poorer hospital outcomes. The study found that in patients hospitalized with acute heart failure, those with low free T3 levels tended to have greater lengths of stay, higher rates of admission to the intensive care unit, and greater requirement for invasive mechanical ventilation. [29]

Patient Education

Patients can be assured that this is a transient phenomenon and that normalization of findings on thyroid function tests is expected with the patient's recovery from NTI. [30]
