Angina pectoris was initially described by Heberden in 1772 and is considered to be the hallmark of ischaemic heart disease. However, with the advent of selective coronary angiography, clinicians were confronted with a conundrum as some patients with unmistakable angina had angiographically normal epicardial coronary arteries. This apparent disparity between the clinical symptoms and the angiographic findings appeared to be resolved when it was demonstrated that affected patients had electrocardiographic and metabolic evidence of ischaemia. Thus, it was hypothesized that the angina experienced by these patients was due to myocardial ischaemia secondary to coronary microvascular dysfunction. This new disorder was referred to as cardiac syndrome X and is typically characterized by exertional angina, electrocardiographic evidence of ischaemia on stress testing, angiographically smooth epicardial coronary arteries, and no other recognized
