应用二维超声心动图Simpson法,在尚无临床心衰征象、静息左室射血分数正常的49例高血压病患者中,检测出伴有左室肥厚的28例病人在踏车极量运动时左心收缩功能的反应低于无左室肥厚组(21例)及年龄配对的血压正常对照组(23例)。提示伴有左室肥厚的高血压病患者收缩期储备功能已受损。
Application of two-dimensional echocardiography Simpson method, in the absence of clinical signs of heart failure, resting left ventricular ejection fraction of 49 cases of hypertensive patients, detected with left ventricular hypertrophy in 28 patients in treadmill extreme Left ventricular systolic function was lower in patients with exercise than in left ventricular hypertrophy (n = 21) and age-matched normotensive controls (n = 23). Tip hypertensive patients with left ventricular hypertrophy systolic reserve function has been impaired.
