Reversible Cardiomyopathies

A Reversible Cardiomyopathy?

Some traditional cardiomyopathies are well known. For instance peripartum cardiomyopathy. Complete recovery occurs in 50% percentage. Similarly tachycardiomyopathy can be caused by a heavy burden of ventricular ectopics, or by an incessant supraventricular tachycardia, or by repeated episodes of ventricular tachycardia. Ensite or Cartographic mapping and ablation of the arrhythmia can abolish t...

Reversible heart failure: toxins, tachycardiomyopathy and mitochondrial abnormalities.

Heart failure is usually a relentless condition associated with a poor prognosis. Triggered by a physiological insult, maladaptive neurohumoral processes result in an ever-spiralling deterioration of cardiovascular function. However, there are certain underlying conditions which are associated with a temporary reduction in contractile function leading to reversible heart failure. These conditio...

Reversible cardiomyopathy in a patient with juvenile hemochromatosis.

Selenium deficiency, reversible cardiomyopathy and short-term intravenous feeding.

We report the case of a patient with Crohn's disease receiving short-term postoperative parenteral nutrition supplemented with trace elements who nevertheless became selenium deficient with evidence of a cardiomyopathy. This was fully reversible with oral selenium supplementation. Current parenteral feeding regimes may not contain enough selenium for malnourished patients.

Reversible dilated cardiomyopathy caused by idiopathic hypoparathyroidism

Dilated cardiomyopathy (DCM) is usually an idiopathic disease with a poor prognosis. Hypocalcemia is a rare and reversible cause of DCM. Here, we report a 50-year-old female with DCM, induced by idiopathic hypoparathyroidism, that improved after treatment with calcium.
