Up to 50% of patients who undergo elective coronary angiography for stable chest pain symptoms that are mainly related to exercise and typical enough to suggest the presence of obstructive coronary artery disease (CAD) are found to have normal or near-normal coronary arteries.1 The mechanisms responsible for angina chest pain in these patients are heterogeneous; accordingly, their identification…

Coronary artery spasm (CAS) is an established cause for anginal chest pain, the cardinal symptom of myocardial ischaemia, in patients with angiographically unobstructed coronary arteries. Evidence from large clinical studies has revealed that about 50% of patients undergoing diagnostic coronary angiography for suspected coronary artery disease (CAD) had either normal or near normal coronary…

Erectile dysfunction (ED) is generally defined as the persistent (at least 6 months) inability to achieve and maintain penile erection sufficient to allow satisfactory sexual performance.1 It is a common condition, and recent studies predict a higher prevalence of ED in the future.2 It is estimated that ED has affected more than 150 million men worldwide and this number will reach approximately…

The endothelium, which was initially considered to be a semipermeable barrier separating lumen from vessel wall, is now recognised as a complex endocrine organ responsible for a variety of physiological processes vital for vascular homeostasis. These include the regulation of vascular tone, luminal diameter and blood flow; haemostasis and thrombolysis; platelet and leucocyte vessel-wall…

Myocardial blood flow (MBF) must respond to changes in metabolic conditions and oxygen requests to meet the needs of myocytes, and autoregulation plays a mayor role in the control of coronary circulation.1–3 It has been demonstrated that, as a coronary artery is progressively narrowed, resting flow does not change at first, but maximal flow (achieved by injecting a vasodilator) decreases…
