Coronary ischemia is a medical term for not having enough blood through the coronary arteries. Coronary ischemia is linked to heart disease as well as heart attacks. It is also known as cardiac ischemia.〔Potochny, Evy. "Cardiac Ischemia Symptoms." LiveStrong. Demand Media, 9 Mar. 2010. Web. 6 Nov. 2010.〕 ==Causes== Coronary artery disease (CAD) occurs when fatty substances get stuck to the walls of coronary arteries, which narrows the arteries and constricts blood flow. This causes a lack of oxygen and blood to the heart, which can result in a myocardial infarction (heart attack).〔("Coronary Artery Disease." Adult Health Advisor (July 2009): 1. Consumer Health Complete. Web. 4 Nov. 2010. )〕 CAD leads to constricted arteries, which leads to a lack of blood flowing through the arteries as well as oxygen, a process called atherosclerosis.〔(Ischemic Heart Disease. Ischemic Heart Disease, n.d. Web. 6 Nov. 2010. )〕 Atherosclerosis is the most common cause of coronary ischemia.〔 CAD can be contracted over time. Certain factors play into this, for example, a family history of CAD. Other factors include smoking, high blood pressure, diabetes,obesity, inactive lifestyle and high cholesterol.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Coronary ischemia」の詳細全文を読む スポンサード リンク
