Blunted flow response at angina onset in CAD; hypothesis-generating for ischemia thresholds, should not yet change practice.
How does progressive elevation of heart rate by atrial pacing affect coronary hemodynamics in patients with coronary artery disease compared to those with normal coronary arteries?
Patients with coronary artery disease can exhibit normal coronary blood flow and resistance responses to increased metabolic demand up until the point of coronary insufficiency and angina.
Yoshida et al. (1971) studied this question.
