systolic

The National Institutes of Health study, known as the systolic blood pressure intervention trial ( Sprint), followed 9300 people who were over the age of 50.

美国国立卫生研究院（National Institutes of Health，简称NIH）的这项名为“收缩压干预试验”（Sprint）的研究，追踪了9300名50岁以上的研究对象。

Methods 432 subjects with heart failure due to systolic dysfunction ( EF < 0.45) were enrolled between April 1996 and January 2001 in the GRACE study ( Genetic Risk Assessment of Cardiac Events), a single center study at the University of Pittsburgh Medical Center.

方法432例患者来源于美国匹兹堡大学医疗中心的心血管事件基因危险性评价研究组，均有收缩功能障碍性心力衰竭〔射血分数（EF）

Regression analysis implied that impairment of BHI was significantly related to the severities of LA, increased age and elevated mean systolic blood pressure ( P0.01).

BHI与LA的严重程度、年龄的增长以及平均收缩压的升高显着相关（P0.01）。
