Diabetic patients with chronic coronary syndrome
Coronary microvascular dysfunction (CMD) is a common condition which often correlates with adverse cardiovascular events in those with diabetes mellitus. A recently developed method of assessing coronary microvascular dysfunction, coronary angiography-derived index of microcirculatory resistance (caIMR), is wire- and hyperaemic agent free. In this study the prognostic impact of caIMR was evaluated on clinical outcomes (with the main endpoint being major adverse cardiac events) of patients with diabetes mellitus and chronic coronary syndrome. caIMR predictions can allow for a risk classification strategy for the management of diabetic patients, allowing clinicians to understanding their clinical outcomes.
This review by Zhang W et al. aimed to evaluate the coronary angiography-derived index of microcirculatory resistance as a method for assessing coronary microvascular dysfunction in relation to diabetic patients.
Further research is needed as there is little data for this technique, especially when using patients who have not undergone revascularisation. This research will allow for a better understanding of the potential of this method.
