Which therapy is not recommended for patients with stable myocarditis?

In patients with stable myocarditis, the use of mechanical circulatory support is not recommended. Mechanical circulatory support devices, such as left ventricular assist devices (LVADs), are typically reserved for patients who are experiencing severe heart failure or cardiogenic shock rather than those who are stable. Stable myocarditis often involves inflammatory processes that may improve with appropriate medical therapy rather than invasive interventions.

On the other hand, therapies like intravenous immunoglobulin, loop diuretics, and corticosteroids may have a role in managing myocarditis under certain conditions. Intravenous immunoglobulin can help modulate immune responses, loop diuretics can alleviate symptoms of fluid overload, and corticosteroids may reduce inflammation. However, the decision to use these therapies must be individualized based on the patient's specific clinical situation and the underlying cause of myocarditis.

Thus, opting for supportive but less invasive measures is more appropriate for patients with stable myocarditis compared to mechanical circulatory support.
