Stable Angina (SA) is a common condition in patients with coronary heart disease, with a prevalence of around 2–4% of the general population in western European countries. In patients with cardiovascular disease, angina is a condition that substantially affects quality of life (QoL) [1,2], which is negatively related to the frequency of anginal episodes [3,4]. Despite a number of effective pharmacological treatments and the success of interventional cardiology, SA remains a cause of significant disability and impaired QoL for many patients [5].
