【摘要】：目的:探討急性ST段抬高型心肌梗死(STEMI)患者經(jīng)皮冠狀動(dòng)脈介入治療(PCI)前后心率校正的T波峰末間期(Tpec)變化過(guò)程及其與惡性室性心律失常(MVA)的關(guān)系。方法:納入接受PCI的STEMI患者494例,分別在PCI前、PCI后(1 h、6 h、12 h、24 h、48 h)、出院時(shí)記錄Tpec。根據(jù)患者PCI后Tpec是否降至100 ms分為Tpec≥100 ms組(n=73)和Tpec100 ms組(n=421),比較兩組患者的MVA發(fā)生率。根據(jù)患者PCI后是否發(fā)生MVA又分為MVA組(n=94)和無(wú)MVA組(n=400),分析PCI前后Tpec變化過(guò)程與MVA發(fā)生的關(guān)系。采用Logistic多因素回歸分析發(fā)生MVA的危險(xiǎn)因素。結(jié)果:STEMI患者PCI后,Tpec≥100 ms組較Tpec100 ms組的MVA發(fā)生率明顯增高(34.2%vs 9.3%,P0.05)。發(fā)生MVA的STEMI患者PCI后Tpec降低緩慢且呈波動(dòng)趨勢(shì),而無(wú)MVA的患者在術(shù)后6 h即降至100 ms以下,呈逐漸下降趨勢(shì)(P0.05)。PCI后Tpec持續(xù)高于100 ms是發(fā)生MVA的獨(dú)立危險(xiǎn)因素(比值比=4.79,95%可信區(qū)間:2.28~10.08,P0.05)。結(jié)論:STEMI患者PCI后Tpec持續(xù)降低緩慢(≥100 ms)是發(fā)生MVA的危險(xiǎn)因素,對(duì)于STEMI患者的危險(xiǎn)分層具有一定參考價(jià)值。
[Abstract]:Objective: to investigate the changes of heart rate corrected T wave interval (Tpeca) in patients with acute ST-segment elevation myocardial infarction (STEMI) before and after percutaneous coronary intervention (PCI) and its relationship with malignant ventricular arrhythmia (MVA). Methods: a total of 494 patients with PCI were enrolled in the study. The patients were treated with STEMI before and after PCI for 1 h, 6 h, 12 h, 24 h and 48 h, respectively, and then recorded at the time of discharge. According to whether the Tpec decreased to 100ms after PCI, the patients were divided into Tpec 鈮，
