Carr Z, Agarkov D, Li J, Charchaflieh J, Brenes-Bastos A, Freund J, Zafar J, Schonberger R, Heerdt P. Implementation of Brief Submaximal Cardiopulmonary Testing in a High-Volume Presurgical Evaluation Clinic: Feasibility Cohort Study. JMIR Perioperative Medicine 2025, 8: e65805. PMID: 39773953, PMCID: PMC11888076, DOI: 10.2196/65805.Peer-Reviewed Original ResearchThis study investigates the feasibility of implementing brief submaximal cardiopulmonary testing in high-volume presurgical clinics, showing it efficiently identifies lower functional capacity compared to traditional surveys in under 20 minutes.
