摘要 目的观察慢性肾脏病(chronic kidney disease,CKD)4-5期患者钙磷代谢紊乱与心瓣膜钙化及心血管事件发生的关系。方法入选2008年1月至2010年3月在大连医科大学附属第二医院肾内科住院的CKD4~5期患者130例,所有患者均行超声心动检查,根据超声心动结果分为A组:心瓣膜有钙化组;B组:心瓣膜无钙化组,检测2组患者血钙、磷,钙磷乘积、甲状旁腺激素(PTH)水平,并评价上述指标与心瓣膜钙化及心血管事件的关系。结果 2组患者血脂、血压、血肌酐无统计学差异[胆固醇(4.46±2.12)mmol/l比(5.54±2.36)mmol/L;三酰甘油(3.20±1.35)mmol/L比(2.78±1.35)mmol/L;收缩压(151.25±15.56)mmHg比(147.88±12.21)mmHg;舒张压(90.88±12.94)mmHg比(93.13±10.33)mmHg;血肌酐(886.13±485.01)umol/l比(625.13±213.02)umol/l,P均>0.05],CKD患病时间A组长于B组(35.13±12.87)月比(29.25±12.76)月,P<0.05],2组比较有统计学意义。A组患者血钙、磷、血钙磷乘积、PTH水平均高于B组[血钙(2.42±0.64)mmol/L比(1.80±0.49)mmol/L;血磷(2.35±0.36)mmol/l比(1.68±0.38)mmol/l;血钙磷乘积(5.47±1.43)比(4.04±0.46);PTH(650.52±259.90)pg/nl比(374.28±125.24)pg/nl,P均<0.05],2组比较差异有统计学意义。A组患者中发生慢性心力衰竭的患病率高于B组(46.6%比27.8%,P<0.05),但2组患冠心病、心源性猝死的比例差异无统计学意义(心绞痛8.6%比8.3%;心肌梗死1.7%比1.4%;心源性猝死1.7%比1.4%,P均>0.05)。结论 CKD患者患病时间越长,血钙磷代谢紊乱越重,心瓣膜钙化发生率越高,心血管事件的发病率越高。
