The participants were cardiac patients who underwent CRT or CRT\u2010D device implantation (\n n<\/jats:italic>\n \u2009=\u20093859). The primary outcome was whether CPET was performed after device implantation. Unpaired t\u2010tests and chi\u2010squared tests were used to compare the characteristics of the CPET (+) and CPET (\u2212) groups. Multivariate analysis was used to identify factors associated with CPET performance. CPET was performed in 134 patients (3%). The CPET (\u2212) group was older and had lower Barthel Index (BI) scores at discharge. CPET (+) patients had a higher rate of cardiac rehabilitation. Multivariate analysis revealed that age\u2009<\u200970\u2009years and BI score\u2009\u2265\u200985 at discharge were associated with CPET implementation. In\u2010hospital cardiac rehabilitation is also an important determinant.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The CPET implementation after CRT or CRT\u2010D was low. Emphasizing the importance of CPET may improve these rates. Future studies should explore strategies to increase its use in this patient population.<\/jats:p>\n
