【摘要】：目的探讨斑点追踪成像技术对于提高高血压合并冠心病检出率的作用,以期在高血压患者中及早发现合并冠心病的患者,从而采取措施减轻或延缓冠心病的进展,为控制心血管疾病的发生、发展以及改善预后提供依据。资料与方法回顾性分析2013年1月—2015年4月中山大学第一附属医院及江门市中心医院住院患者共166例,其中高血压组(HT组)42例、冠心病组(CAD组)35例、高血压合并冠心病组(HT+CAD组)49例及对照组40例。应用常规测量方法及斑点追踪成像技术分析166例患者的常规测值与左心室17节段的峰值应变值。结果 CAD组及HT+CAD组患者总平均峰值应变、峰值应变最小值及病变区域峰值应变平均值较HT组及对照组均减低,差异有统计学意义(P0.05)。受试者工作特性(ROC)曲线分析显示,总平均应变、病变节段峰值应变平均值及最小峰值应变值均可估测冠心病的发生,其曲线下面积分别为0.710、0.761和0.700;根据ROC截断值,当患者同时满足病变区域峰值应变平均值≥-18%、总平均应变值≥-19%、各节段峰值应变的最小值≥-6%时,作为阳性诊断冠心病的敏感度为56.3%,特异度为83.5%。结论斑点追踪自动功能显像技术能提供高血压合并冠心病患者节段室壁运动障碍可靠、客观的数据,提高其临床检出率。
[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，
