Chronic myocardial ischemia results from a temporary disbalance between supply of oxygen to myocardium and consumption of oxygen by myocardium. The most frequent cause of ischemic heart disease is atherosclerosis of the coronary arteries. At present, diagnosis of coronary impairment is for practical reasons not possible until myocardial ischemia is detectable. Despite the current pharmacological treatments, data from the recent studies justify stratification of prognosis of patients with chronic ischemic heart disease into subgroups with low, medium and high risk. Mean annual mortality is below 1% in patients with low risk, 1-2% in patients with medium risk and above 2% in patients with high risk. Revascularization procedures might improve prognosis in certain subgroups of patient with chronic ischemic heart disease. Revascularization also decreases the incidence of ischemic episodes and improves the left ventricle function in some subgroups.

The significance of ST-segment changes in an electrocardiogram need not be always as clear-cut as we used to think. Minor problems usually represent only the ST-segment depressions in the presence of typically manifested problems and established coronary artery disease. The same holds true for ST-segment elevations: in addition, they definitively superior to ST-segment depressions. Among other categories, silent ischemia denotes only a part of what is or can be seen. This article deals with other conditions associated with changes in ST segments and variable symptoms with changeable clinical implications.
