High baPWV accompanied by hypertension increase the risk of cardio-cerebrovascular events, which may be due to: arteriosclerosis is the direct cause of cardio-cerebrovascular events, and the increase of baPWV is the incidence indicator of atherosclerosis. Atherosclerosis causes vascular wall hardening and blood vessel lumen narrowing, which is a risk factor for hypertension. Prolonged high BP increases the arterial hemodynamic load, which decreases arterial compliance and finally develops to arteriosclerosis. High baPWV causes the damage of hypertensive target organs and on the other hand leads to high BP, which is a vicious cycle , which increases the risk of cardio-cerebrovascular events. In addition, our study also found that the effect of baPWV on stroke was more than BP, maybe because arteriosclerosis is systemic disease. About 70% of stroke patients have atherosclerosis , it is easy to have cerebral infarction because of involvement of the cerebral arterial stenosis; the affected blood vessels become vulnerable to rupture and bleed due to stiffness and fragileness.
High baPWV combined with hypertension can increase the risk of cardio-cerebrovascular events, and the predictive value of high baPWV combined with high BP on cardio-cerebrovascular events is better than that of only high baPWV or hypertension.
