Relationship between exercise hyperpnea, hemodynamics, and blood gases before and during glyceryl trinitrate infusion in patients with exercise-induced elevation of pulmonary artery wedge pressure.

BACKGROUND The mechanisms underlying the excessive ventilatory response to exercise in patients with cardiac failure are still not fully understood. HYPOTHESIS This study was undertaken to investigate the mechanisms behind exercise hyperpnea in patients with exercise-induced left ventricular dysfunction. METHODS In 18 patients, aged 57-82 years, all… CONTINUE READING
