A prospective study was carried out in 499 patients admitted to a coronary care unit (CCU) in order to evaluate the incidence of clinically significant electrolyte disturbances. Low serum potassium values (less than 3.6 mmol l) occurred in 7% of the CCU patients and low serum magnesium values (less than 0.70 mmol l-1) in 6%. Few patients had low values of both these ions (1.9%). In 49 patients the contents of these electrolytes in muscle biopsies were similar to the values of control subjects and were unrelated to treatment with diuretics. Serum calcium was determined in 444 of the patients and was above the reference range in 11 (2.5%). If we consider their concomitant parathyroid hormone (PTH) values, primary hyperparathyroidism was likely to occur in at least seven patients (1.5%). Patients with acute myocardial infarction (AMI) had mean PTH and electrolyte values similar to those of individuals without this disease. In conclusion, the present study indicates that clinically important disturbances of magnesium, potassium or calcium homeostasis are rare among unselected patients admitted to a CCU.

Typical symptoms of acute myocardial infarction led to admission of a 66-year-old female. Creatine kinase (CK) was 720 U/l on admission and together with CK-MB of 108 U/l fitted the clinical picture. The ECG showed complete left bundle branch block. The patient died a few hours later in cardiac failure. Massive hypercalcaemia of 6.2 mmol/l and hyperphosphataemia of 1.6 mmol/l suggested acute primary hyperparathyroidism already clinically which later could be verified by a parathormone level of more than 100 000 ng/l ("C-terminal assay"). At necropsy chief cell adenoma of the epithelial bodies was found, typical changes of primary hyperparathyroidism in the skeleton and kidneys, and disseminated calcifications and fresh necroses of cardiac muscle. The coronaries were normal. This is the first clinical report of fatal acute primary hyperparathyroidism due to hypercalcaemia-induced myocardial necroses.

The authors present the case of a 78-year-old female patient who was admitted on account of acute pancreatitis complicated by acute myocardial infarction. The authors detected in the patient a serum repeatedly high calcium levels and high levels of intact parathormone. Scintigraphic examination revealed marked foci in the middle of the neck at the level of the inferior pole of the thyroid gland. These examinations confirmed the diagnosis of primary hyperparathyroidism. In view of the patient a serious condition, conservative treatment of hypercalcaemia and acute pancreatitis and myocardial infarction was started. The patient was released into domiciliary care after 40 days in hospital in a state of cardiopulmonary compensation, with cystic transformation of the pancreas and without signs of acute pancreatitis.
