A hyperaemiás és a nonhyperaemiás intrakoronáriás nyomásarányok együttes értékelésének diagnosztikus jelentősége

Abstract

condition in the coronary artery. We explore the possibilities of the combined measurements for detecting myocardial ischemia caused by either epicardial or microvascular components. We also propose an algorithm for the evaluation of the functional relevance of the coronary stenosis starting by the less invasive image based FFR calculations followed by invasive non-hyperemic and hyperemic pressure ratio measurements in case of the interval between 0.75-0.85 of the image based FFR values. In our opinion this complex strategy provides comprehensive evaluation of the pathophysiological state of the coronary disease beyond the morphological features of the stenoses and allows us to choose the most appropriate therapy for the patient.
