Arterial Stiffness as an Antecedent in the Pathogenesis of Primary Hypertension
Abstract: Over the past 50 years, it has been postulated that abnormality in resistance vessels play an important and critical role in the pathogenesis of hypertension as these vessels maintain the steady-flow hemodynamic in the circulation. Accordingly, antihypertensive therapies were designed to alter the peripheral vascular resistance or cardiac output, resulting in a reduction in mean arterial pressure. However, in recent years, many studies have emphasized the role of arterial stiffness …
