What is Radionuclide ejection fraction: Comparison of response to treadmill and bicycle exercise about?

Most exercise radionuclide studies utilise the supine bicycle ergometer during imaging, although exercise on a treadmill results in greater cardiovascular stress. Twenty-three patients were studied to compare the radionuclide left ventricular ejection fraction (LVEF) estimated immediately following treadmill exercise with that obtained at peak supine bicycle exercise in patients with coronary artery disease (CAD) and patients with normal coronary arteries. In 14 patients with CAD the rest LVEF was 47 +/- 7% (mean +/- SD) by first pass and 49 +/- 10% by equilibrium blood pool techniques. Immediately following maximum treadmill exercise, 13 of the 14 patients with coronary artery disease showed either no change or a decrease in LVEF, the LVEF was 49 +/- 7% (P = NS) and 47 +/- 8% (P = NS) by first pass and equilibrium determinations respectively. In comparison the LVEF during peak supine bicycle exercise decreased significantly to 42 +/- 12% (P less than 0.01). In nine patients with angiographically normal coronary arteries the rest LVEF was 51 +/- 4% by first pass and 54 +/- 6% by equilibrium, increasing to 67 +/- 7% (P less than 0.01) and 64 +/- 7% (P less than 0.01) respectively fo
