Orthostatic hypotension is an independent risk factor for cardiovascular morbidity and mortality. Arterial stiffness has been shown to be a pathophysiological mechanism linking orthostatic hypotension and increased cardiovascular risk. This study aims to evaluate the relationship between arterial stiffness, orthostatic hypotension and subendocardial viability ratio (SEVR) and moreover to identify the main predictors of orthostatic hypotension, carotid-femoral pulse wave velocity (PWV-cf) and SEVR.

住院老年人心内膜下灌注损伤、动脉僵硬度和体位性低血压之间的关系。

直立性低血压是心血管疾病发病率和死亡率的独立危险因素。动脉僵硬已被证明是一种病理生理机制，将体位性低血压与心血管风险增加联系起来。本研究旨在评估动脉僵硬度、直立性低血压和心内膜下存活率 (SEVR) 之间的关系，并进一步确定直立性低血压、颈动脉-股动脉脉搏波速度 (PWV-cf) 和 SEVR 的主要预测因子。
