Angina pectoris 2023: With and without obstructive coronary artery disease: Epidemiology, diagnosis, prognosis, and treatment.

ABSTRACT

Angina contributes to significant morbidity worldwide. The evaluation of angina is variable and complicated by multiple factors. The diagnosis is often focussed on epicardial disease despite the knowledge that chest pain can be due to cardiac, non-cardiac, macro, and microvascular causes. Standardised diagnostic pathways and novel approaches to angina assessment may offer the opportunity to improve our understanding of angina and apply a personalised approach to treatment.
