Preprocedural muscle strength and physical performance and the association with functional decline or mortality in frail older patients after transcatheter aortic valve implementation: a systematic review and meta-analysis

Abstract

Background A significant number of older patients planned for transcatheter aortic valve implantation (TAVI) experience a decline in physical functioning and death, despite a successful procedure. Objective To systematically review the literature on the association of preprocedural muscle strength and physical performance with functional decline or long-term mortality after TAVI. Methods We followed the PRISMA guidelines and pre-registered this review at PROSPERO (CRD42020208032). A systematic search was conducted in MEDLINE and EMBASE from inception to 10 December 2021. Studies reporting on the association of preprocedural muscle strength or physical performance with functional decline or long-term (>6 months) mortality after the TAVI procedure were included. For outcomes reported by three or more studies, a meta-analysis was performed. Results In total, two studies reporting on functional decline and 29 studies reporting on mortality were included. The association with functional decline was inconclusive. For mortality, meta-analysis showed that low handgrip strength (hazard ratio (HR) 1.80 [95% confidence interval (CI): 1.22–2.63]), lower distance on the 6-minute walk test (HR 1.15 [95% CI: 1.09–1.21] per 50 m decrease), low performance on the timed up and go test (>20 s) (HR 2.77 [95% CI: 1.79–4.30]) and slow gait speed (<0.83 m/s) (HR 2.24 [95% CI: 1.32–3.81]) were associated with higher long-term mortality. Conclusions Low muscle strength and physical performance are associated with higher mortality after TAVI, while the association with functional decline stays inconclusive. Future research should focus on interventions to increase muscle strength and physical performance in older cardiac patients.

Can resistance prehabilitation training bring additional benefits in valvular cardiac surgery? protocol for a randomized controlled trial

“…This condition has a pronounced impact on peripheral musculature. Research indicates that lower preoperative muscle density is associated with increased postoperative mortality rates [19][20][21] and a higher likelihood of pulmonary complications [20,[22][23][24]. Additionally, reduced manual grip strength correlates with higher mortality, longer hospital stays, and increased risk of postoperative complications [21,23,24].…”

The Trajectory of Nutritional Status and Physical Activity before and after Transcatheter Aortic Valve Implantation

“…Despite low invasiveness of the transcatheter intervention, it is shown that approximately one in three patients experience physical decline or are deceased within six months after the procedure [ 18 ]. Poor nutritional status and physical inactivity during the preprocedural period are shown as predominant risk factors for negative outcomes [ 19 , 20 , 21 ]. It is suggested that in this patient population, prehabilitation could be effective in improving outcomes [ 11 , 12 ].…”
