- W1984367079 abstract "This study evaluated the ability of exercise Doppler echocardiography to identify hemodynamic changes due to cardiac medication. Twenty young healthy volunteers (mean age 30 years) underwent continuous wave Doppler examination from the suprasternal notch at rest, during each stage of a standard exercise protocol and immediately after exercise. On completion of the control test, each subject received either 60 to 80 mg of propranolol or 120 mg of verapamil orally, and the same exercise protocol was repeated after 90 min. During the control test, values for modal velocity, acceleration and flow velocity integral all increased significantly from baseline (p less than 0.0002 for each). When exercise was repeated after propranolol administration, values for all Doppler measurements were significantly altered. Modal velocity at baseline was significantly lower after propranolol when compared with control (0.53 +/- 0.11 versus 0.63 +/- 0.17 m/s; p less than 0.0001). Similarly, modal velocity at maximal exercise was significantly lower after propranolol (1.11 +/- 0.2 versus 1.25 +/- 0.21 m/s; p less than 0.0001). The effect of propranolol on acceleration was even greater, with blunting of baseline (11.4 +/- 2 versus 15.4 +/- 5 m/s per s; p less than 0.0005) and exertional (33.4 +/- 10 versus 56.3 +/- 15 m/s per s; p less than 0.0001) acceleration. The flow velocity integral during exercise was greater after propranolol (14.1 +/- 3.1 versus 10.1 +/- 3.2 cm; p less than 0.0005) than during the control test. Verapamil failed to influence any Doppler-measured index of aortic blood flow.(ABSTRACT TRUNCATED AT 250 WORDS)" @default.
