左心声学造影对缺血性心脏病患者冠状动脉微循环障碍的评估OA
Diagnostic value of left ventricular echocardiography in coronary microcirculation disturbance in patients with ischemic heart disease
目的:评估左心声学造影在缺血性心脏病患者冠状动脉微循环障碍中的应用价值,通过分析左心声学造影相关检测参数,为缺血性心脏病患者冠状动脉微循环障碍的临床评估提供参考依据.方法:选取 2023 年 1 月—2024 年 9 月在我院治疗的 80 例缺血性心脏病患者为研究组.对患者一般资料进行比较,结合左心声学造影结果,将研究对象分为缺血性心脏病合并冠状动脉微循环障碍组(障碍组)与缺血性心脏病不合并冠状动脉微循环障碍组(正常组).选取同期在我院进行心脏功能检查的 80 例正常人作为健康对照组.通过左心声学造影、三维超声检查等方法检测患者心功能指标、心脏超声三维空间参数、左心室收缩及舒张功能、左心室整体纵向应变(LVGLS)、心肌血流量(MBF).结果:障碍组患者全心房应变(GAS)、整体纵向应变(GLS)、左心室射血分数(LVEF)、左心室每搏输出量(LVSV)、MBF、LVGLS 水平低于正常组(P<0.05),高血压患病率高于正常组(P<0.05).结论:左心声学造影可以通过对缺血性心脏病患者高血压发生情况、心脏三维空间检查、左心室收缩及舒张功能、MBF 等进行评估,为冠状动脉微循环障碍的临床评估提供可靠支撑.
Objective:To evaluate the application value of left ventricular echocardiography(LVECG)in coronary micro-circulation disorders in patients with ischemic heart disease,and to provide reference for the clinical evaluation of coronary microcirculatory dysfunction in patients with ischemic heart disease by analyzing the relevant parameters detected by LVECG.Methods:A total of 80 patients with ischemic heart disease who were treated in our hospital from January 2023 to September 2024 were selected as the study group.Based on a comparison of the patients'general characteristics and LVECG results,the subjects were divided into two groups:the ischemic heart disease with coronary microcirculatory impair-ment group(impairment group)and the ischemic heart disease without coronary microcirculatory impairment group(normal group).Concurrently,80 healthy individuals who underwent cardiac function tests in our hospital during the same period were selected as the healthy control group.Cardiac function indicators,three-dimensional spatial parameters of cardiac ultra-sound,left ventricular systolic and diastolic functions,left venticular global longitudinal strain(LVGLS),and myocardial blood flow(MBF)were observed and measured using LVECG and three-dimensional ultrasound examinations.Results:The levels of global atrial strain(GAS),global longitudinal strain(GLS),left ventricular ejection fraction(LVEF),left ventricular stroke volume(LVSV),MBF,and LVGLS in the disorder group were lower than those in the normal group(P<0.05),and the prevalence of hypertension was higher than that in the normal group(P<0.05).Conclusion:LVECG can provide reliable support for the clinical assessment of coronary microcirculatory disorders by evaluating the occurrence of hypertension,three-dimensional spa-tial examination of the heart,left ventricular systolic and diastolic functions,and MBF in patients with ischemic heart disease.
