Hypocalcemia-associated cardiomyopathy, a rare but serious condition, presents challenges in diagnosis and management. Severe hypocalcemia resulting from hypoparathyroidism can precipitate rare yet reversible cases of dilated cardiomyopathy. This case report reported a 31-year-old woman with heart failure precipitated by hypoparathyroidism following thyroidectomy. Despite conventional heart failure treatments, her condition persisted until correction of hypocalcemia. Treatment involved calcium supplementation and guideline-directed heart failure therapy. Significant improvement was observed then. Hence, monitoring serum calcium levels is imperative when conventional heart failure therapies fail to yield improvement, particularly in patients with a history of thyroidectomy. Sustaining clinical awareness and vigilance concerning hypocalcemia is crucial in managing heart failure, considering its possibility as a reversible cause.
