Ischemic heart disease oxygen demand

O Ischemic heart disease results from an imbalance between myocardial oxygen demand and oxygen supply that is most often due to coronary atherosclerosis. Common clinical manifestations of ischemic heart disease include chronic stable angina and the acute coronary syndromes of unstable angina, non-ST-segment elevation myocardial infarction, and ST-segment elevation myocardial infarction.

Ischemic heart disease (IHD) is also called coronary heart disease (CHD) or coronary artery disease. The term ischemic refers to a decreased supply of oxygenated blood, in this case to the heart muscle. Ischemic heart disease is caused by the narrowing of one or more of the major coronary arteries that supply blood to the heart, most commonly by atherosclerotic plaques. Atherosclerotic plaques may impede coronary blood flow to the extent that cardiac tissue distal to the site of the coronary artery narrowing is deprived of sufficient oxygen in the face of increased oxygen demand. Ischemic heart disease results from... [Pg.64]

Ischemic heart disease (IHD) is caused primarily by coro-nary atherosclerosis, a very common disease in the U.S. population, and results in an imbalance between oxygen supply and demand with resulting ischemia. [Pg.261]
