摘要
目的 探究高血压性心脏病(HHD)患者心室病变的超声心动图显像特征及发生心功能异常的危险因素。方法 选取2021年7月至2023年12月收治的68例HHD患者为观察组,并依据左室舒张功能情况将观察组分为左室舒张功能正常组和左室舒张功能减低组,另选取同期入院体检的68名健康者为对照组。研究对象均接受超声心动图检查,比较超声心动图检查结果,分析HHD患者左室舒张功能的影响因素。结果观察组的左房前后径、室间隔厚度、左室后壁厚度、升主动脉内径、主动脉窦内径、左室舒张末期前后径大于对照组,左室射血分数低于对照组(P<0.05)。观察组的左房增大、室间隔增厚、左室后壁增厚、升主动脉增宽、主动脉窦部增宽、左室增大及左室舒张功能减低发生率高于对照组(P<0.05)。左室舒张功能减低组的左房前后径、室间隔厚度、左室后壁厚度、升主动脉内径、主动脉窦内径、左室舒张末期前后径大于左室舒张功能正常组(P<0.05)。二元Logistic回归分析结果显示,高血压分级3级、收缩压、非高密度脂蛋白胆固醇(non-HDL-C)是HHD患者左室舒张功能减低的危险因素,高密度脂蛋白胆固醇(HDL-C)是其保护因素(P<0.05)。结论 超声心动图在HHD早期心脏结构及舒张功能异常的评估中具有重要价值,高血压分级、收缩压、non-HDL-C、HDL-C是HHD患者左室舒张功能减低的影响因素。
Objective To investigate the echocardiographic imaging features of ventricular lesions in patients with hypertensive heart disease(HHD)and risk factors for abnormal cardiac function.Methods A total of 68 patients with HHD admitted from July 2021 to December 2023 were selected as observation group,and the observation group was divided into normal left ventricular diastolic function group and reduced left ventricular diastolic function group according to the left ventricular diastolic function.In addition,68 healthy people who were admitted in the hospital for physical examination during the same period were selected as control group.The subjects were examined by echocardiography.The results of echocardiography were compared and the influencing factors of left ventricular diastolic function in patients with HHD were analyzed.Results The left atrial anteroposterior diameter,interventricular septal thickness,left ventricular posterior wall thickness,ascending aortic diameter,aortic sinus diameter,left ventricular end-diastolic anteroposterior diameter of the observation group were larger than those of the control group,and the left ventricular ejection fraction was lower than that of the control group(P<0.05).The incidences of left atrial enlargement,ventricular septal thickening,left ventricular posterior wall thickening,ascending aorta widening,aortic sinus widening,left ventricular enlargement and left ventricular diastolic function reduction in the observation group were higher than those in the control group(P<0.05).The left atrial anteroposterior diameter,interventricular septal thickness,left ventricular posterior wall thickness,ascending aortic diameter,aortic sinus diameter and left ventricular end-diastolic anteroposterior diameter in the reduced left ventricular diastolic function group were larger than those in the normal left ventricular diastolic function group(P<0.05).Binary Logistic regression analysis results showed that hypertension grade 3,systolic blood pressure and non-high-density lipoprotein cholesterol(non-HDL-C)were risk factors for left ventricular diastolic dysfunction in HHD patients,and high-density lipoprotein cholesterol(HDL-C)was a protective factor(P<0.05).Conclusion Echocardiography has important value in the evaluation of early cardiac structure and diastolic dysfunction in HHD.Hypertension grade,systolic blood pressure,non-HDL-C and HDL-C are the influencing factors of left ventricular diastolic dysfunction in HHD patients.
