血脂

關(guān)系A(chǔ)CS與血脂狀態(tài)有報道ACS患者應(yīng)激狀態(tài)下，血脂濃度有較大波動。AMI發(fā)生24h后，TC、LDL-C、HDL-C、apoA1和apoB均有明顯下降，TG卻增加。4～5d后變化最為明顯，2～3個月后可回到基線狀態(tài)。此時LDL和HDL顆粒性質(zhì)發(fā)生了變化。作者認為，對于ACS患者，無論基線血脂濃度如何，都需要積極地應(yīng)用他汀類藥物進行強化降脂治療。趙水平.中華心血管病雜志,2013,41(7):

542-543結(jié)果結(jié)論：TC、TG、LDL-C、ApoB水平升高和HDL-C、ApoA1水平降低可能是ACS發(fā)病的危險因素，血脂6項指標聯(lián)合檢測有助于預(yù)測ACS的發(fā)生并監(jiān)控病情的變化。丁玲新等.海南醫(yī)學院學報,2011,11:1476-1478ACS與血脂狀態(tài)另一篇報道：經(jīng)冠脈造影診斷為CHD的367例患者，其中男性261例，女性106例，年齡29～89(59.5±11.0)歲。268例ACS患者，99例非ACS患者作為對照，對兩組患者的Lp(a)、HDL-C、ApoAl、TC、TG、LDL-C以及ApoB水平進行觀察。結(jié)果ACS與血脂狀態(tài)另一項研究納入333例ACS患者，男性232例（69.7%），女性101例（30.3%），年齡62±10.63歲。其中UA257例（77.2%），NSTEMI50例，STEMI26例（7.8%），在發(fā)病期對患者血漿血脂濃度進行檢測。結(jié)果結(jié)論1.在ACS患者中，血脂異常較為常見2.大于50%是HDL-C＜1.0mmol/L孫斌.鄭州大學,2010年,學位論文ACS降脂治療臨床益處Effects
