Key result
The eSTICO method for noninvasive assessment of cardiac output during exercise showed no significant difference compared to open circuit measures at peak exercise (12.39 vs 13.96 L/min, p>0.05).
Why the study?
Assessing cardiovascular hemodynamics during exercise provides clinical insights but remains challenging to acquire in clinical settings.
Does the eSTICO method accurately measure cardiac output during exercise in healthy adults compared to established methods?
Population
14 healthy subjects (12 male, 2 female)
Comparison
eSTICO method vs OpCircCO and VO2CO methods

Does the eSTICO method accurately measure cardiac output during exercise in healthy adults compared to established methods?
Mean Difference: -1.6 (95% CI -6.3–3.5)
Absolute Event Rate: 12.39% vs 13.96%
p-value: p=> 0.05
A novel noninvasive method using systolic timing intervals (eSTICO) provides a feasible and relatively accurate assessment of cardiac output during exercise in healthy adults.
Kim et al. (2023) conducted a cross-sectional in Healthy adults (n=14). eSTICO method vs. Open circuit CO measure (OpCircCO) and oxygen consumption-based CO (VO2CO) was evaluated on Cardiac output at peak exercise (MD -1.6, 95% CI -6.3-3.5, p=> 0.05). The eSTICO method for noninvasive assessment of cardiac output during exercise showed no significant difference compared to open circuit measures at peak exercise (12.39 vs 13.96 L/min, p>0.05).
