摘　　要：BACKGROUND Hypoparathyroidism is a rare disease that may occur due to primary or secondary etiologies.The estimated incidence in the United States is 24–37/100000 personyears.Congestive heart failure associated with hypocalcemia due to hypoparathyroidism is an even rarer presentation.CASE SUMMARY Here,we present a 64-year-old woman with congestive heart failure following hypocalcemia.The patient was transferred to our emergency department with complaints of rapidly progressive dyspnea,shortness of breath and heaviness of the chest for 4 d.She had a history of undergoing thyroidectomy and partial tracheotomy 2 years prior due to a malignant thyroid tumor.Muscle spasms had been present 1 year ago,and cataracts were treated with intraocular lens replacement in both eyes.Most tests were within normal ranges,except serum calcium at 1.33 mmol/L(2.20–2.65 mmol/L),ionized calcium at 0.69 mmol/L(1.15–1.29 mmol/L),and parathyroid hormone at<1.0 pg/mL(12–88 pg/mL).Echocardiography revealed an ejection fraction of 28.48%.Cardiac function was quickly reversed by restoring the serum calcium concentration.Significant improvements were noted with an ejection fraction of up to 48.50%at follow-up.CONCLUSION For patients with potential hypocalcemia,monitoring calcium levels and dealing with hypocalcemia in time to avoid serious complications are important.
