In this prospective randomized study, resting and exercise hemodynamics were determined in the nonmedicated state before ("entry") and 1 year after coronary bypass surgery in 38 patients, and at entry and 1 year in 40 patients treated medically. The surgical group showed a significant decrease in mean pulmonary arterial wedge pressure during exercise (entry 23.5 +/- 6.1 [standard error of the mean] mm Hg, 1 year 18.9 +/- 1.0, P less than 0.02); an increase in cardiac index during exercise… CONTINUE READING
