Spectrum of global left ventricular responses to supine exercise

摘要: Left ventricular function was evaluated with rest and supine bicycle exercise-multigated blood pool scans in 53 patients who had previously undergone coronary angiography for evaluation of a chest pain syndrome. There were 21 normal ( 50% narrowing 1 or more major arteries). Thirty-two (60%) receiving propranolol at the time study. The patient group significant increase mean ejection fraction (EF) during exercise (+0.08 ± 0.09), while CAD no (0 0.11; p 2 ) but demonstrated change (1 12 ml/m ;
