摘要

Coronary blood flow velocity was measured during handgrip exercise using breath-hold velocity encoded cine magnetic resonance imaging. Peak diastolic coronary flow velocity in the left anterior descending artery was 20.6 ± 9.3 cm/s (mean ± SD) at baseline and increased significantly to 31.1 ± 16.4 cm/s after exercise (50.7 ± 31.3%increase, p <0.01).
