260x260px There is no specific known cause for<unk>  but rather a multitude of risk factors that act together. It is believed that the lack of blood flow caused by a<unk>  disease and enhanced pain perception are two of the factors that may cause it. The<unk>  dysfunctions refer to the abnormalities in the very small blood vessels of the heart. The narrowing of these vessels may lead to lack of oxygen in specific areas of the cardiac muscle causing chest pain. Several studies have shown that patients living with<unk>  may have an enhanced pain perception, and usually feel more intense chest pain than individuals without<unk> . The risk factors include abdominal obesity, meaning excessive fat tissue in and around the abdomen, atherogenic dyslipidemia which is a blood fat disorder, and elevated blood pressure. Other risk factors are insulin resistance or intolerance to glucose, prothrombotic state or proinflammatory state. Older people are more at risk to develop this condition, and there is some evidence that suggests that there are genetic mutations that predispose to the syndrome. Women are more prone to this condition than men, as well as those who have a history of heart disease in the family.
