Abstract
In a sample of 306 patients with positive treadmill test results, we found that patients with silent ischemia had a higher systolic blood pressure at onset of ST depression than patients with painful ischemia. We conclude that systolic blood pressure at the time of ischemia influences the experience of angina during exercise in a manner consistent with acute activation of baroreceptors and resulting antinociception.
