摘要 目的探讨2型糖尿病患者骨质疏松与冠状动脉钙化的关系。方法根据双能X线骨密度检查结果,将82例老年2型糖尿病患者分成骨质疏松组与非骨质疏松组,分别进行冠状动脉双源CT检查,计算冠状动脉总钙化积分(TCS),同时测定血钙(Ca)、磷(P)、甲状旁腺素(PTH)水平等。结果骨质疏松组与非骨质疏松组比较,血钙[(2.32±0.15)mmol/L对(2.04±0.20)mmol/L]、PTH[(5.64±1.97)pmol/L对(5.01±1.93)pmol/L]、TCS[(374.4±433.5)分对(242.5±224.8)分],差异均有统计学意义(t值分别为5.790、5.331、2.248,P〈0.05)。相关性分析显示,2型糖尿病患者TCS与L2、L3、L4、股骨颈骨密度呈负相关(r值分别为-0.310、-0.246、-0.290、-0.284,P〈0.05),与钙、PTH呈正相关(r值分别为0.324、0.575,P〈0.05)。结论2型糖尿病患者骨质疏松与冠状动脉钙化之间存在一定的相关性,钙磷代谢异常及代偿性PTH水平升高可能起到一定的作用。 Objective To investigate the association of osteoporosis and coronary artery calcification in elderly patients with type 2 diabetes mellitus (T2DM). Methods A total of 82 elderly T2DM patients underwent dual-energy x-ray absorptiometry scanning (DXA) of lumbar spine and femur neck for getting bone mineral density (BMD), and dual-source computed tomography (DSCT) of coronary artery for calculating calcification score and total calcification score (TCS). All subjects were divided into two groups: osteoporosis group and non-osteoporosis group. The levels of serum calcium (Ca), parathyrin (PTH), phosphorus (P), alkaline phosphatase (AKP), triglyceride (TG), total cholesterol (TC), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein- cholesterol (LDL-C) and glycosylated hemoglobin (HbAlc) were detected. Results Compared with non-osteoporosis group, the levels of serum Ca, PTH and TCS were higher [(2.32 ±0.15) mmol/L vs. (2.04±0.20) mmol/L; (5.64± 1.97) pmol/L vs. (5.01± 1.93) pmol/L; (374.4± 433.5) scores vs. (242.5±224.8) scores, t=5.790, 5. 331 and 2. 248, all P〈0.05; inosteoporosis group. Correlation analysis showed TCS was negatively associated with BMD of L2 4 and femur neck, while was positively associated with serum Ca and PTH (r=0. 310, 0. 246, 0. 290, 0. 284 and 0. 324, 0. 575 all P〈0.05). Conclusions Osteoporosis is associated with coronary atherosclerosis. TCS could be considered as an index for judging the relationship between osteoporosis and coronary atherosclerosis.
