摘要

Reactive hyperemia (RH) is a well-established technique for noninvasive assessment of peripheral microvascular function and a powerful predictor of all-cause and cardiovascular morbidity and mortality (3, 52, 53, 68, 83). In its simplest form, RH represents the magnitude of limb reperfusion following a brief period of ischemia induced by arterial occlusion. Over the past two decades, investigators have employed a variety of methods, including brachial artery velocity by Doppler ultrasound (52), tissue reperfusion by near-infrared spectroscopy (NIRS) (62, 74, 76), limb distension by venous occlusion plethysmog-raphy (23, 28), and peripheral artery tonometry (11, 72), to measure RH. Regardless of the tools used to measure RH, the fundamental interpretation common to these studies has been that blunted RH signifies (micro)vascular dysfunction.
