【摘要】：目的:探討超聲心動圖定量評價急性心肌梗死后患者雙房的重構情況及形變能力。方法:選取我院確診為急性心肌梗死患者(AMI組)61例及32例經(jīng)心電、冠狀動脈(冠脈)CT或造影檢查排除冠心病的患者(對照組),心臟超聲檢查測得雙房內徑,最大、最小及收縮前容積(VFilaX、Vmin及Vp),計算雙心房被動射血分數(shù)(LAPEF/RAPEF)及主動射血分數(shù)(LAAEF/RAAEF);留取動態(tài)圖像進行二維斑點追蹤脫機分析,獲取雙房備節(jié)段房壁左室收縮期的縱向峰值應變(LS)、應變率(SRs)、左室舒張早期峰值應變率(Sre)與左室舒張晚期峰值應變率(Sra)。并計算其平均峰值應變率(mSRs、mSRe、mSRa)。結果:與對照組比較,AMI組短期內雙房重構無顯著差異,雙房主動射血分數(shù)顯著增高(P0.05),雙房被動射血分數(shù)顯著減低(P0.05);mSRs、mSRe絕對值均減低(均P0.05),mSRa絕對值增高(P0.05)。結論:AMI早期雙房均開始發(fā)生重構,但雙房形變比容積變化更顯著,二維斑點追蹤應變成像能早期、敏感地定量評價AMI后雙房功能的變化。
[Abstract]:Objective: to investigate the quantitative evaluation of biatrial remodeling and deformability in patients with acute myocardial infarction by echocardiography. Methods: 61 patients with AMI and 32 patients with AMI were selected from our hospital. Coronary artery (coronary artery CT or angiographic examination excluded coronary heart disease patients (control group, echocardiography measured the biatrial diameter, the largest, The minimum and pre-systolic volume of VFilaXT Vmin and VPU were calculated to calculate the biatrial passive ejection fraction (LAPEFR) and the active ejection fraction (LAAEFR / RAAEFF). Dynamic images were retained for two dimensional speckle tracing offline analysis. The longitudinal peak strain of left ventricular systolic phase (LSN), strain rate (SRS), left ventricular early diastolic peak strain rate (SreS) and left ventricular late diastolic peak strain rate (SRAA) were obtained. The mean peak strain rate of left ventricular peak strain rate was calculated. Results: the mean peak strain rate was calculated and compared with that of the control group. There was no significant difference in biatrial remodeling between AMI group and AMI group. The bilocular active ejection fraction (AEF) increased significantly (P 0.05), and the bilocular passive ejection fraction (P0.05) decreased significantly (P 0.05%). Conclusion the bilocular remodeling begins in the early stage of AMI, but the bilocular deformation is more significant than the volume change. Two-dimensional speckle tracing strain imaging can sensitively and quantitatively evaluate bilocular function after AMI.
