One case report of repeated chest tightness and palpitation cured after strengthening calcium supplementation / 中华内分泌外科杂志

ABSTRACT

The incidence of parathyroid hyperfunction is high and its clinical manifestations are diverse. Some patients develop chest tightness and palpitations as the main discomfort, which may be caused by the hypocalcemia and hypercalcemia related to negative calcium balance and parathyroid hyperfunction. We report a case of 53 years old male with parathyroid hyperfunction who was diagnosed with osteoporosis before and received conventional regular supplementation of vitamin D and calcium supplements. However, his condition worsened and he developed chest tightness and palpitation. After 1 month of sufficient supplementation of calcium, the symptoms of chest tightness and palpitation disappeared completely. Then we continued to provide the patients enough vitamin D and calcium supplementation actively. After 1 year of follow-up, the patient's condition was stable. His discomfort of chest tightness and palpitation never recurred, and all the bone metabolism indicators returned to normal.
