Key result
Arm exercise elicited angina pectoris at a smaller work load and lower pulmonary oxygen uptake than leg exercise in patients with coronary artery disease.
Why the study?
Does arm exercise compared to leg exercise alter the circulatory adaptation and onset of angina pectoris in patients with coronary artery disease?
Population
10 patients with signs of coronary artery disease
Comparison
Arm exercise with stepwise increased work loads vs Leg exercise with stepwise increased work loads

Arm exercise may provoke earlier angina in CAD; leaves open tailored testing and rehabilitation protocols pending prospective data.
Cross-Sectional (n=10)
Does arm exercise compared to leg exercise alter the circulatory adaptation and onset of angina pectoris in patients with coronary artery disease?
Arm exercise elicits angina at lower workloads and oxygen uptake than leg exercise due to steeper increases in heart rate and blood pressure, explaining the earlier onset of symptoms during upper extremity exertion in CAD patients.
Wahren et al. (1971) conducted a cross-sectional in Coronary artery disease (n=10). Arm exercise vs. Leg exercise was evaluated on Onset of angina pectoris and circulatory adaptation (pressure-time per minute, work load, oxygen uptake). Arm exercise elicited angina pectoris at a smaller work load and lower pulmonary oxygen uptake than leg exercise in patients with coronary artery disease.
