1、非慢性腎臟病人群血清鈣磷水平與冠狀動(dòng)脈鈣化和狹窄的相關(guān)性研究熊斌王建靈李丹王杰蘇立[通信作者]蘇立,電話:13996215033,郵箱:sulicq@163.com(400016重慶,重慶醫(yī)科大學(xué)附屬第二醫(yī)院心血管內(nèi)科)[摘要]目的研究非慢性腎臟病人群血清鈣磷水平與冠狀動(dòng)脈鈣化和狹窄的相關(guān)性其臨床意義。方法回顧性分析2013年1月至2014年6月重慶醫(yī)科大學(xué)附屬第二醫(yī)院881名行冠狀動(dòng)脈血管成像的住院患者臨床資料,分析血鈣(Ca)、磷(P)及鈣磷乘積(CPP)與冠脈鈣化和冠脈狹窄的相關(guān)性。結(jié)果40
2、3名患者存在冠脈鈣化,占46%;至少有1支血管狹窄≥50%共163名,占19%。有冠脈鈣化和無冠脈鈣化組的平均血Ca水平分別是8.95mg/dL和9.02mg/dL(P=0.013),血P水平分別是3.53mg/dL和3.47mg/dL(P=0.082),CPP分別是31.7mg2/dL2和31.3mg2/dL2(P=0.323)。冠脈狹窄≥50%和狹窄<50%兩組的血Ca、P和CPP均無顯著差異。以Agatston積分100分為界點(diǎn)預(yù)測(cè)冠脈狹窄≥50%的敏感性和特異性分別是65%和93%。多因素
3、分析發(fā)現(xiàn),隨著血Ca水平的升高,血Ca水平與冠脈鈣化(CACS>100)的相關(guān)性逐漸增強(qiáng)并且有顯著統(tǒng)計(jì)學(xué)意義,與~8.6mg/dL組相比,Ca:8.7~8.9mg/dL(OR:1.68,P=0.045);Ca:9.0~9.3mg/dL(OR:1.69,P=0.047);Ca:9.4~mg/dL(OR:1.89,P=0.048),但P和CPP與冠脈鈣化(CACS>100)未見顯著相關(guān)性;血Ca、P及CPP各水平與冠脈狹窄≥50%未見顯著相關(guān)性。結(jié)論隨著血Ca水平升高,其與冠脈鈣化相關(guān)性顯著并且逐漸增
