This lack of association was present although the examined type 2 DM nephropathy patients showed clinical complications more frequently than HD patients with other renal diseases: higher dialysis related mortality rate [3], higher prevalence of CAD including myocardial infarction [4], lower serum PTH, and lower frequency of parathyroidectomy and treatment with cinacalcet, all of them predictive for higher tendency to adynamic bone disease [7]. Here, PTH is linked to coronary artery disorder.
