Uncomfortable chest while walking

Condition in which imbalance between myocardial oxygen supply and demand results in myocardial hypoxia and accumulation of waste metabolites, most often caused by atherosclerotic disease of the coronary arteries (often termed coronary artery disease)

Uncomfortable sensation in the chest and neighboring anatomic structures produced by myocardial ischemia

Chronic pattern of transient angina pectoris, precipitated by physical activity or emotional upset, relieved by rest within a ew minutes

Episodes often associated with temporary depression of the ST segment, but permanent myocardial damage does not result

Typical anginal discomfort, usually at rest, which develops because of coronary artery spasm rather than an increase of myocardial oxygen demand

Episodes often associated with transient shifts of the ST segment, usually ST elevation

Also termed Prinzmetal angina / Vasospastic angina

Asymptomatic episodes o myocardial ischemia

Can be detected by electrocardiogram and other laboratory techniques

Pattern of increased requency and duration of angina episodes produced by less exertion or at rest

High requency o progression to myocardial infarction if untreated

Region of myocardial necrosis usually caused by prolonged cessation of blood supply

Most often results rom acute thrombus at site of coronary atherosclerotic stenosis

may be a first clinical mani estation of ischemic heart disease, or there may be a history of angina pectoris
