Hypocalcemic cardiomyopathy with heart failure: A rare Case report

Area of Science:

• Cardiology
• Endocrinology
• Internal Medicine

Background:

• Hypocalcemia is an uncommon etiology of reversible dilated cardiomyopathy.
• Refractory heart failure necessitates a thorough investigation for underlying causes, including electrolyte imbalances.

Observation:

• A 55-year-old female presented with refractory heart failure.
• Her condition was attributed to hypocalcemia secondary to primary hypoparathyroidism and vitamin D deficiency.

Findings:

• Correction of hypocalcemia and vitamin D deficiency led to dramatic improvement in cardiac symptoms.
• Left ventricular function and structure recovered following calcium level normalization.

Implications:

• Hypocalcemia should be considered in the differential diagnosis of refractory heart failure.
• Early identification and management of hypocalcemia can prevent irreversible cardiac damage and reduce mortality.
