每搏输出量(SV，M型超声心动图)与脉压(PP)的比率被认为是总动脉顺应性的估计，并已被证明与正常成年人的身体尺寸、年龄和心率有关。用SV/体表面积(SVI)和SV/PP与先前建立的方程(%SV/PP)预测的比值，对294例高血压患者(98例女性)的SV/PP进行了估算。在基线时，50例在接下来的10年中有心血管事件的患者表现出更高的脉压和更低的SV/PP、SVI/PP和%SV/PP(均P
Ratio of stroke volume (SV, M-mode echocardiography) to pulse pressure (PP has been proposed as an estimate of total arterial compliance and has been shown to be related to body size, age, and heart rate in normal adults. SV/PP was estimated in 294 hypertensive patients (98 women) as a raw value by use of SV/body surface area (SVi) and by the ratio of SV/PP to the value predicted by a previously developed equation (%SV/PP). At baseline, the 50 patients who had cardiovascular events over the following 10 years exhibited higher PP and lower SV/PP, SVi/PP, and %SV/PP (all P
