Key result
Short-term physical training for 2 weeks after coronary arterial bypass grafting significantly decreased the V•E–V•CO2 slope from 38.9 to 35.1 (p<0.05) and increased peak cardiac output.
Why the study?
Does short-term physical training improve ventilatory response and cardiac output during exercise in patients after CABG?

Absolute Event Rate: 35.1% vs 41.5%
p-value: p=<0.05
Short-term physical training initiated two weeks after CABG significantly improves exercise hyperpnea and increases cardiac output during exercise.
Adachi et al. (2001) conducted an RCT in Post-Coronary Arterial Bypass Grafting (CABG) (n=57). Short-term physical training vs. Sedentary convalescence was evaluated on Minute ventilation-carbon dioxide output (V•E–V•CO2) slope (p=<0.05). Short-term physical training for 2 weeks after coronary arterial bypass grafting significantly decreased the V•E–V•CO2 slope from 38.9 to 35.1 (p<0.05) and increased peak cardiac output.
