Sympathetic stimulation with parasympathetic withdrawal mimics the hemodynamic changes of maximal exercise in man

Summary:To assess neurohumoral and hemodynamic responses to exercise in patients with exertional angina, we measured plasma norepinephrine (NE) concentrations in 23 patients with exertional angina (with no heart failure) and compared the results with their coronary artenographic findings. The 23 patients were divided into two groups:14 cases with multiple vessel disease (MVD) and 9 cases with one-vessel disease. At resting state there were no significant differences between the two groups in levels of NE. At maximal exercise there were no significant differences between the groups in increases of heart rate, blood pressure, and rate-pressure product, but exercise-induced increase of plasma NE (%) was significantly larger in MVD (131.6f95.4%) (meanfSD) than inone-vessel disease (69.0f45.3%) (p
