摘要
目的 :研究高血压左室重构对心脏收缩功能的影响。方法 :采用彩色超声心动图对 2 2 6例原发性高血压与 5 1例正常对照组进行心脏结构和心功能的测定。结果 :正常构型组、向心性重构组 :血压 ( BP)轻、中度升高 ,收缩功能正常。向心性肥厚组 :BP最高 ,收缩功能处于亚临床状态 ,心肌收缩性明显受损。离心性肥厚组 :左心室射血分数 ( EF)、短轴缩短率 ( FS)、m FS最低 ,左室收缩功能明显下降。结论 :不同左室构型的高血压心功能改变不同 ,治疗。
Objective: To study the influence of the left ventricular (LV) remodelling caused by essential hypertension on cardiac function. Methods: By means of colour echocardiography to measure the cardiac structure and function of the 226 cases of patients with essential hypertension and 51 cases of control subjects. Results: Normal pattern and concentric remodelling groups: Blood pressure (BP) increase slightly,the systolic function of LV is normal. Concentric hypertrophy group: BP is higher than that of the other three groups, the LV systolic function stays in the subclinical condition, the myocardial contractility damaged seriously. Eccentric hypertrophy group: Ejection fraction (EF)、 endocardial fractional shortening (FS) and midwall fraction shortening (mFS) are the lowest, LV diastolic function fall down obviously. Conclusion: The different changes of the LV function in the four groups lead to the different treatment and prognosis.;
