Summary
Three women presented with tetany and congestive cardiac failure due to hypocalcemia. Treatment with calcium and vitamin D analogs proved effective for managing this rare cardiac condition.
Area of Science:
- Cardiology
- Endocrinology
- Biochemistry
Background:
- Presents three women with tetany and congestive cardiac failure (CCF).
- Absence of prior cardiac disease or alcohol abuse noted.
- One patient had a history of cataract removal and epilepsy.
Observation:
- All patients exhibited prolonged Q-T intervals on ECG and cardiomyopathy on echocardiograms.
- Biochemical findings included hypocalcemia, hyperphosphatemia, and normal serum urea.
- Inappropriately low parathyroid hormone levels were observed in all cases.
Findings:
- Tetany and CCF responded to intravenous calcium and magnesium infusions.
- Diuretics and digoxin were used in some cases.
- Long-term management with 1-alpha-hydroxyvitamin D3 and calcium supplements resulted in sustained recovery.
Implications:
- Highlights a rare presentation of hypocalcemia mimicking primary cardiac conditions.
- Emphasizes the importance of biochemical evaluation in unexplained cardiomyopathy and tetany.
- Suggests effective therapeutic strategies involving calcium and vitamin D supplementation for similar cases.
