From frailty to function after cardiac surgery: a call for nurse-led holistic innovation

This invited commentary refers to ‘Frailty changes after cardiac surgery: better or worse?’, by C.-H. Teng et al., https://doi.org/10.1093/eurjcn/zvaf089. The research by Teng et al.,1 ‘Frailty changes after cardiac surgery: better or worse?’, provides valuable insights into the dynamic relationship between cardiac surgery and frailty trajectories. As the global burden of cardiovascular disease grows alongside ageing populations, with cardiac intervention volumes remaining persistently high,2 understanding post-operative frailty trajectories becomes increasingly critical for clinical decision-making. This secondary analysis of 273 patients undergoing various cardiac procedures demonstrates that 92.5% of patients maintained or improved their frailty status at 6 months post-operatively when assessed using the Fried frailty phenotype. Most remarkably, 79.4% of patients classified as frail at baseline showed measurable improvement. The study’s longitudinal design represents a critical methodological advancement beyond the cross-sectional approaches that continue to dominate frailty research.3 They employed the validated Fried frailty phenotype, which assesses five physical domains: unintentional weight loss, exhaustion, weakness, slowness, and low physical activity.4 This ensures methodological consistency with established frameworks while enabling meaningful comparisons. The inclusion of a ‘worst-case scenario’ analysis, where deaths and losses to follow-up were conservatively classified as frailty worsening, strengthens the findings by accounting for potential attrition bias.
