In addition, more frequent analyses of serum PTH, but not serum calcium, were reported to result in increased detection of PHPT in a Swedish population (n = 11,000, 1992–2000).(10) This emphasis on PTH measurement is supported by the Parathyroid Epidemiology and Audit Research Study from Scotland, in which intact PTH rather than serum calcium measurement predicted all‐cause mortality and cardiovascular disease.(11) The incidence of PHPT has risen across different European countries. The gene discussed is PTH; the disease is cardiovascular disorder.
