Coronary microvascular vasodilator capacity is substantially associated with coronary pressure waveform and dicrotic notch morphology, with or without concomitant epicardial disease. A prominent dicrotic notch is associated with preserved microvascular vasodilatory capacity and adequate resting microvascular tonus without relative hyperaemic state, cumulatively indicating a better microcirculatory health.
Keywords: Coronary microvascular dysfunction; Dicrotic notch; Pressure waveform.
