Description
Background and Aims
Coronary function testing to measure index of microcirculatory resistance (IMR) and coronary flow reserve (CFR) may be performed at the time of invasive coronary angiography to aid the diagnosis of microvascular angina. Intravenous (IV) adenosine infusion is used to induce stable hyperaemia. Logistics and systemic side-effects limit clinical adoption. Iodinated contrast medium (iohexol) is used during standard diagnostic angiography and induces transient, submaximal hyperaemia. We investigated the feasibility and diagnostic value of contrast-derived indices of coronary microvascular function.
Methods and Results
Consecutive patients with suspected angina who underwent clinically-indicated invasive coronary angiography at 2 regional cardiac centres between Jul 2021 and Nov 2022 were included. Coronary function testing was performed using a temperature/pressure diagnostic …
