1、生長(zhǎng)分化因子15程度與急性冠脈綜合征患者心功能分級(jí)的相關(guān)性2900字 目的:對(duì)生長(zhǎng)分化因子-15程度growth differentiation factor-15,GDF-15?c急性冠脈綜合征acute coronary syndrome,ACS患者心功能分級(jí)的臨床意義進(jìn)展研究。方法:58例ACS患者按紐約心臟病協(xié)會(huì)NYHA的心功能分級(jí)方法分為NYHA 級(jí)組21例、NYHA 級(jí)組22例、NYHA 級(jí)組10例、NYHA 級(jí)組5例四個(gè)亞組。25例行冠脈造影排除冠心病的NYHA 級(jí)患者為對(duì)照組。檢測(cè)各組B型利鈉肽B-type natnuretic peptide,BNP等生化指標(biāo),運(yùn)用ELISA

2、法測(cè)定GDF-15程度。結(jié)果:與對(duì)照組相比,ACS患者各亞組的GDF-15、BNP程度顯著高P0.01,且各組GDF-15、BNP程度隨著心力衰竭嚴(yán)重程度的升高而上升P0.05,GDF-15、BNP程度均與心衰程度呈正相關(guān)r=0.681、0.653,P0.001。且GDF-15、BNP兩者間亦呈現(xiàn)正相關(guān)性r=0.726,P0.001。結(jié)論:ACS患者的GDF-15程度升高顯著,與BNP呈正相關(guān),可對(duì)ACS患者的心功能進(jìn)展較有價(jià)值的危險(xiǎn)分層,利于斷定ACS患者心力衰竭程度。 畢業(yè) 生長(zhǎng)分化因子-15; 急性冠脈綜合征; B型利鈉肽doi:10.14033/j ki.cfmr.2022.23.01

13、竭、心肌肥厚、冠心病等多種心血管疾病相關(guān)15-17,是ACS預(yù)后的預(yù)測(cè)因子,可能有助于評(píng)估ACS患者的預(yù)后,并有助于制定最正確治療策略18-19。長(zhǎng)期的研究已經(jīng)提示GDF-15具備心血管保護(hù)作用,因此本文通過(guò)分析GDF-15程度與ACS患者心功能分級(jí)的意義,希望進(jìn)一步提醒GDF-15的表達(dá)程度與ACS患者心功能級(jí)別的相關(guān)性。假如能證實(shí)GDF-15有類似BNP的預(yù)示心力衰竭程度的作用,且可作為特異性相對(duì)較高的預(yù)測(cè)因子敏感反響心功能情況,以此來(lái)制定針對(duì)性的有效措施干預(yù),以減少ACS急性心血管事件的發(fā)生。本研究顯示,ACS患者各心功能分級(jí)亞組的血清GDF-15、BNP程度較對(duì)照組均顯著高。且隨著心衰

14、嚴(yán)重程度的升高,ACS患者NYHA 級(jí)組、級(jí)組、級(jí)組、級(jí)組中血清GDF-15、BNP程度亦逐漸上升,且GDF-15程度與心衰程度、GDF-15程度與BNP程度間均呈正相關(guān)。故本研究提示,GDF-15可以作為類似于BNP預(yù)示心力衰竭嚴(yán)重程度的獨(dú)立預(yù)測(cè)因子,與BNP結(jié)合、并根據(jù)NYHA分級(jí)可以識(shí)別ACS的高危患者。這對(duì)于ACS患者心功能分級(jí)的評(píng)估和進(jìn)一步治療具有臨床意義,但由于GDF-15的檢測(cè)目前尚停留在根底研究階段,其在心血管疾病方面的詳細(xì)分子機(jī)制尚不明確,因此進(jìn)一步在臨床診療中完全應(yīng)用,證據(jù)尚欠缺,有待研究者的?M一步研究來(lái)證實(shí)。參考文獻(xiàn)1 Kempf T,Eden M,Strelau J,
