Changes in pulse pressure × heart rate, hs-CRP, and arterial stiffness progression in the Chinese general population: a cohort study involving 3978 employees of the Kailuan Company

Journal of Geriatric Cardiology 2019年第9期16卷 710-716页

作者： Hao XUE Jun-Juan LI Jian-Li WANG shuo-hua chen Jing-Sheng GAO Yun-Dai chen Shou-Ling WU Department of Cardiology Chinese People’s Liberation Army General Hospital Beijing China Department of Cardiology Kailuan Hospital Hebei United University Tangshan China

Background Pulse wave velocity(PWV) is a marker of arterial stiffness, which represents sub-clinical atherosclerosis. Pulsatile stress and high-sensitivity C-reactive protein(hs-CRP) are associated with arteriosclerosis. However, there is no prospective data confirming whether changes in pulsatile stress and inflammatory markers affect the progression of arterial stiffness. The aim of this study was to investigate the relationships over time between the effects of changes in pulsatile stress and hs-CRP, and arterial stiffness progression during a 2-year follow-up. Methods We performed a longitudinal study involving 3978 participants. All participants underwent a physical examination in 2010–2011 and 2012–2013, during which we measured participants’ hs-CRP levels, brachial–ankle pulse wave velocity(ba PWV), and pulsatile stress. Results Baseline hs-CRP was correlated with ba PWV(r = 0.18, P = 0.000);however the correlation was weaker than that with systolic blood pressure(r = 0.65), pulsatile stress(r = 0.57), and rate-pressure product(r = 0.58). Multiple linear regression analysis demonstrated that changes in pulsatile stress, mean arterial pressure, and low-density lipoprotein-C(LDL-C) were positively correlated with changes in ba PWV, with correlation coefficients of 0.27, 0.25, and 0.07, respectively, but not with changes in hs-CRP. Moreover, each 100-a U increase in pulsatile stress, 1 mm Hg increase in mean blood pressure, and 1 mmol/L increase in LDL-C was associated with a 3 cm/s, 4.78 cm/s, and 17.37 cm/s increase in ba PWV, respectively. Conclusions Pulsatile stress increases are associated with arterial stiffness progression, but that changes in hs-CRP had no effect on arterial stiffness progression. Hs-CRP may simply be a marker of inflammation in arterial stiffness and has no association with arterial stiffness progression.
