Early Recovery of Oxygen Kinetics in Heart Failure: A Systematic Review of Oxygen Kinetics During the First Minute of Recovery afterCardiopulmonary Exercise Testing in Heart Failure

Key Points

This research aims to evaluate the recovery of oxygen kinetics after exercise in heart failure patients.
Systematic review of oxygen kinetics during recovery after cardiopulmonary exercise testing (CPET) in heart failure.
Assessment focused on the VO2/t-slope as a diagnostic and prognostic tool.
Evaluation of functional status and disease progression in heart failure patients.
VO2/t-slope is indicated as a valuable diagnostic and prognostic tool in heart failure.
Findings suggest that VO2/t-slope improves post-exercise, highlighting its clinical relevance.
VO2/t-slope remains independent of CPET duration and intensity, unlike VO2peak.

Abstract

VO2/t-slope is a promising diagnostic and prognostic indicator for HF, complementing VO2peak in maximal and submaximal CPET. Its proportional deterioration in HF and improvement post-exercise highlights its role in assessing functional status and disease progression. Unlike VO2peak, VO2/t-slope remains independent of CPET duration and intensity, making it particularly useful for advanced HF stages and revealing Clinical superiority. These findings support VO2/tslope as a valuable tool for HF diagnosis, classification, prognosis, and follow-up. DOI number: 10.37766/inplasy2024.9.0111, registration number INPLASY: 202490111.
