Abstract
- Ischaemia with no obstructive coronary artery disease (INOCA) affects up to 50% of patients referred for coronary angiography for suspected angina. Although originally thought to be benign, recent data shows that patients with INOCA have an adverse prognosis. There are challenges in identifying and managing the underlying cause, which is most often attributed to coronary microvascular disease or coronary vasospasm. This review will cover the clinical relevance and prognosis of INOCA as well as the invasive and non-invasive imaging techniques available to identify the underlying aetiology. Upcoming technological advancements will also be discussed.
