Coronary flow reserve is the capacity of the coronary circulation to augment the blood flow in response an increase in myocardial metabolic demands and has a powerful prognostic significance in different clinical situations. It might assess with invasive and noninvasive technique. Transthoracic echocardiography Doppler is an emerging diagnostic technique, noninvasive, highly feasible, safe for patient and physician, without radiation, and able to detect macrovascular and microvascular anomalies in the coronary circulation. This review aims to describe the benefit and limits of echocardiographic assessment of coronary flow reserve.
冠状动脉血流储备是指冠状动脉循环增加心肌代谢需求时的血液流量的能力,在不同的临床情况下具有强大的预后意义。它可以通过有创和无创技术进行评估。经胸超声心动图多普勒是一种新兴的诊断技术,具有非侵入性、高度可行性、对患者和医生安全、无辐射、能够检测冠状动脉循环中的大血管和微血管异常等优点。本文旨在描述超声心动图评估冠状动脉血流储备的优势和局限性。
