With the aging of the world's population, a large proportion of patients seen in cardiovascular practice are older adults, but many patients also exhibit signs of physical frailty. Cardiovascular disease and frailty are interdependent and have the same physiological underpinning that predisposes to the progression of both disease processes. Frailty can be defined as a phenomenon of increased vulnerability to stressors due to decreased physiological reserves in older patients and thus leads to poor clinical outcomes after cardiovascular insults. There are various pathophysiologic mechanisms for the development of frailty: cognitive decline, physical inactivity, poor nutrition, and lack of social supports; these risk factors provide opportunity for various types of interventions that aim to prevent, improve, or reverse the development of frailty syndrome in the context of cardiovascular disease. There is no compelling study demonstrating a successful intervention to improve a global measure of frailty. Emerging data from patients admitted with heart failure indicate that interventions associated with positive outcomes on frailty and physical function are multidimensional and include tailored cardiac rehabilitation. Contemporary cardiovascular practice should actively identify patients with physical frailty who could benefit from frailty interventions and aim to deliver these therapies in a patient-centered model to optimize quality of life, particularly after cardiovascular interventions.
随着世界人口老龄化,心血管疾病患者中有很大一部分是老年人,但许多患者也表现出身体虚弱的迹象。心血管疾病和虚弱是相互关联的,它们有着相同的生理基础,使这两种疾病都容易进展。虚弱可以定义为由于老年患者生理储备减少而导致对压力源的易感性增加的现象,因此会导致心血管损伤后的临床预后不良。虚弱的发展有多种病理生理机制:认知能力下降、身体活动减少、营养状况不佳和缺乏社会支持;这些危险因素为各种旨在预防、改善或逆转心血管疾病背景下虚弱综合征发展的干预措施提供了机会。目前没有令人信服的研究证明干预措施可以成功改善整体虚弱程度。来自心力衰竭住院患者的新数据表明,与虚弱和身体功能方面的积极结果相关的干预措施是多方面的,包括个性化的心脏康复。当代心血管疾病实践应积极识别身体虚弱的患者,这些患者可能从虚弱干预中获益,并以患者为中心的模式提供这些治疗,以优化生活质量,尤其是在心血管干预之后。
