Does combined interpretation of exercise electrocardiography and cardiopulmonary exercise testing improve the detection of significant coronary artery stenosis in patients undergoing coronary angiography?
Answers are grounded in this paper and cite their sources.
The combined presence of prolonged ST depression and specific oxygen uptake/heart rate changes during CPET may improve the diagnostic accuracy for detecting significant coronary artery stenosis.

Hoshiko et al. (2026) conducted a cohort in Significant coronary artery stenosis (n=127). Combined assessment of exercise-induced ST-segment changes and oxygen uptake/heart rate was evaluated on Significant coronary artery stenosis. Combined assessment of exercise-induced ST-segment changes and oxygen uptake/heart rate was evaluated for detecting significant coronary artery stenosis, which was present in 46.5% of patients.
