[Cardiomyopathy in hypocalcemia]
Insights
Hypoparathyroidism after thyroid surgery can cause hypocalcaemic cardiomyopathy. Prompt calcium and vitamin D3 treatment effectively improved cardiac function in a severe case.
Area of Science:
- Cardiology
- Endocrinology
- Thyroid Surgery
Background:
- Recurrent goiter with tracheal compression necessitated three thyroid operations.
- Post-thyroidectomy hypoparathyroidism can lead to severe hypocalcemia.
Observation:
- A 48-year-old woman presented with severe cardiac failure.
- She had hypocalcaemic cardiomyopathy secondary to hypoparathyroidism.
- No signs of tetany were present, despite severe hypocalcemia.
Findings:
- Treatment with calcium and vitamin D3 normalized serum calcium levels.
- Significant improvement in cardiac status was observed.
- Radiological and echocardiographic findings of cardiac dysfunction resolved.
Implications:
- This case highlights the critical link between mineral metabolism and cardiac function.
- Early diagnosis and management of hypoparathyroidism are crucial for preventing and reversing cardiac complications.
- Treatment with calcium and vitamin D3 can be highly effective in managing hypocalcaemic cardiomyopathy, even in severe presentations.
Abstract:
A 48-year-old woman developed a hypocalcaemic cardiomyopathy, the hypocalcaemia being due to hypoparathyroidism after three previous thyroid operations for goitre with tracheal compression. She had signs of severe cardiac failure, but no tetany. She was put on calcium and vitamin D3 medication which raised calcium concentration. The cardiac status improved, as did the radiological and echocardiographic findings, without the patient having received any diuretics, digitalis or afterload lowering drugs.
