【摘要】：目的探討斑點(diǎn)追蹤成像技術(shù)對(duì)于提高高血壓合并冠心病檢出率的作用,以期在高血壓患者中及早發(fā)現(xiàn)合并冠心病的患者,從而采取措施減輕或延緩冠心病的進(jìn)展,為控制心血管疾病的發(fā)生、發(fā)展以及改善預(yù)后提供依據(jù)。資料與方法回顧性分析2013年1月—2015年4月中山大學(xué)第一附屬醫(yī)院及江門市中心醫(yī)院住院患者共166例,其中高血壓組(HT組)42例、冠心病組(CAD組)35例、高血壓合并冠心病組(HT+CAD組)49例及對(duì)照組40例。應(yīng)用常規(guī)測(cè)量方法及斑點(diǎn)追蹤成像技術(shù)分析166例患者的常規(guī)測(cè)值與左心室17節(jié)段的峰值應(yīng)變值。結(jié)果 CAD組及HT+CAD組患者總平均峰值應(yīng)變、峰值應(yīng)變最小值及病變區(qū)域峰值應(yīng)變平均值較HT組及對(duì)照組均減低,差異有統(tǒng)計(jì)學(xué)意義(P0.05)。受試者工作特性(ROC)曲線分析顯示,總平均應(yīng)變、病變節(jié)段峰值應(yīng)變平均值及最小峰值應(yīng)變值均可估測(cè)冠心病的發(fā)生,其曲線下面積分別為0.710、0.761和0.700;根據(jù)ROC截?cái)嘀?當(dāng)患者同時(shí)滿足病變區(qū)域峰值應(yīng)變平均值≥-18%、總平均應(yīng)變值≥-19%、各節(jié)段峰值應(yīng)變的最小值≥-6%時(shí),作為陽(yáng)性診斷冠心病的敏感度為56.3%,特異度為83.5%。結(jié)論斑點(diǎn)追蹤自動(dòng)功能顯像技術(shù)能提供高血壓合并冠心病患者節(jié)段室壁運(yùn)動(dòng)障礙可靠、客觀的數(shù)據(jù),提高其臨床檢出率。
[Abstract]:Objective to investigate the effect of speckle tracking imaging on the detection rate of hypertension complicated with coronary heart disease (CHD) so as to find out the patient with coronary heart disease (CHD) as early as possible and to take measures to reduce or delay the progress of CHD. In order to control the occurrence, development and improve the prognosis of cardiovascular diseases, data and methods A retrospective analysis of 166 hospitalized patients in the first affiliated Hospital of Sun Yat-sen University and Jiangmen Central Hospital from January 2013 to April 2015 was carried out. 42 cases in hypertension group and 35 cases in CAD group in coronary heart disease group. There were 49 cases of HT CAD group and 40 cases of control group in hypertension complicated with coronary heart disease group. Routine measurement method and speckle tracking imaging technique were used to analyze the routine measurement value and the peak strain value of left ventricular 17 segment. Results CAD group and HT group and HT group were used to analyze the peak strain value of left ventricle. Total mean peak strain in CAD group, The minimum value of peak strain and the mean value of peak strain in lesion area were lower than those in HT group and control group, and the difference was statistically significant (P 0.05). The mean value of peak strain and the minimum peak strain of pathological segment can be used to estimate the occurrence of coronary heart disease. The area under the curve is 0.710 ~ 0.761 and 0.700, respectively. When the patient satisfies the mean value of peak strain 鈮，
