Pulsatile arterial hemodynamics in cardiovascular diseases indicate that the aortic blood pressure curve may be represented by 2 different phenotypes: one in patients 64 years old and younger and the other in subjects older than 65 years. The 2 blood pressure curves may have exactly the same mean arterial pressure (ie, the same cross-sectional area under the curve) but quite different shapes. In older subjects, systolic blood pressure and pulse pressure are higher, whereas diastolic blood pressure is lower than in younger subjects.
心血管疾病中的搏动性动脉血流动力学表明,主动脉血压曲线可能呈现两种不同的表型:一种见于64岁及以下的患者,另一种见于65岁以上的受试者。这两种血压曲线可能具有完全相同的平均动脉压(即曲线下的横截面积相同),但形状却大不相同。在老年受试者中,收缩压和脉压较高,而舒张压低于年轻受试者。
