【摘要】：目的評(píng)估超聲冠狀動(dòng)脈血流成像技術(shù)(CFI)診斷冠狀動(dòng)脈慢血流現(xiàn)象(CSFP)的可行性。方法對(duì)擬診冠心病于我院行冠狀動(dòng)脈造影檢查,明確冠狀動(dòng)脈無(wú)明顯狹窄且冠狀動(dòng)脈慢血流的患者38例,冠狀動(dòng)脈無(wú)慢血流的患者41例。應(yīng)用校正的TIMI血流計(jì)數(shù)(CTFC)及CFI分別測(cè)量冠狀動(dòng)脈血流參數(shù),對(duì)二者的相關(guān)性及CFI診斷CSFP的可行性進(jìn)行分析。結(jié)果 CSFP組及對(duì)照組冠狀動(dòng)脈左前降支超聲血流參數(shù)(PDV、MDV、PDP、MDP)分別與冠狀動(dòng)脈造影CTFC呈負(fù)相關(guān)。對(duì)照組VT與冠狀動(dòng)脈造影CTFC亦呈負(fù)相關(guān)。ROC曲線分析冠狀動(dòng)脈左前降支超聲血流參數(shù)曲線下面積均0.7。結(jié)論 CFI能夠有效、無(wú)創(chuàng)的反映CSFP患者冠狀動(dòng)脈血流的變化,對(duì)CSFP診斷有一定價(jià)值。
[Abstract]:Objective to evaluate the feasibility of echocardiographic coronary artery flow imaging (CFI) in the diagnosis of coronary slow flow (CSFP). Methods Coronary angiography was performed in our hospital. There were 38 patients who had no obvious stenosis of coronary artery and slow flow of coronary artery. Coronary blood flow parameters were measured by corrected TIMI flow count and CFI in 41 patients with no slow flow in coronary artery. Results the ultrasonic blood flow parameters of left anterior descending coronary artery in CSFP group and control group were analyzed. MDP). There was a negative correlation between coronary arteriography (CTFC) and coronary angiography (CTFC) in the control group. The area under the left anterior descending coronary artery flow parameter curve was 0. 7. ... conclusions. CFI can be effective. Non-invasive reflection of coronary blood flow in patients with CSFP is valuable for the diagnosis of CSFP.
