Gait Speed improves EuroSCORE II prediction


Traditionally cardiac surgery risk scores have worse performance in elderly patients. Frailty evaluation may improve EuroSCORE II accuracy in predicting morbimortality


Test the value of gait speed, a clinical marker for frailty, to improve the prediction of mortality and major morbidity in elderly patients undergoing cardiac surgery


A multicenter prospective cohort of patients undergoing coronary artery bypass and/or valve replacement or repair from 12 tertiary care hospitals in São Paulo State/Brazil. Patients were eligible if they were at least 60 years of age. Frailty was defined as slow gait speed, a time taken to walk 5 m of ≥ 6 s. The primary end point was a composite of in-hospital post-operative mortality or major morbidity


The cohort consisted of 241 patients with a mean age of 67,4 ± 8.2 years. One hundred and two patients (42.3%) were classified as slow walkers before cardiac surgery. Slow gait speed patients were more likely to be female (50.9% vs. 19.4%, p = 0.0001), insulin-dependence diabetic (23.5% vs. 13.6%, p = 0.05), had worse EuroSCORE II (3.9% × 1.8%, p = 0.001). Frail patients had more prolonged length of stay (27.5% vs 7.9%, p = 0.001) and more morbimortality (32.4% vs 15.1%, p = 0.002). Slow gait speed was an independent predictor of the composite end point after adjusting for the EuroSCORE II (odds ratio: 2.36; 95% confidence interval: 1.17 to 4.76) and increased EuroSCORE II accuracy from 67% to 71.9% in prediction of morbimortality


Impaired Gait speed patients have more morbimortality. 5-meter gait speed test is an effective way to identify elderly patients at higher risk and is a simple way to improve EuroSCORE II performance
