Asymptomatic Myocardial Ischemia
Archives of Internal Medicine, 1981In the vast majority of patients, angina pectoris is the cornerstone on which the diagnosis and treatment of coronary heart disease are formulated. There is evidence to suggest that transient myocardial ischemia may occur without angina pectoris; such episodes are generally detected during ECG or hemodynamic monitoring.

The concept that myocardial ischemia can be directly related to enhanced coronary vasomotor tone is now widely accepted. Earlier skepticism has, to a large extent, been neutralized by a steady stream of convincing evidence. Doubts, however, remain as to the real incidence of this phenomenon and its precipitating factors.

Annual Review of Medicine, 1988
Silent myocardial ischemia is increasingly recognized as a common phenomenon in a variety of people with coronary artery disease. The natural history is poorly understood, but available data suggest that silent ischemia adversely affects prognosis in all groups studied.

CONCEPTS OF MYOCARDIAL ISCHEMIA [PDF]
Archives of Internal Medicine, 1949 MYOCARDIAL ischemia occurs whenever there exists a discrepancy between the available oxygen supply and the work requirements of the heart muscle. The balance of these two factors is essential for cardiac function. An arterial blood flow below that customarily available for work performance results in myocardial ischemia.

Does perioperative myocardial ischemia lead to postoperative myocardial infarction? By Stephen Slogoff and Arthur S. Keats. Anesthesiology 1985; 62:107-14. Reprinted with permission. To determine if a relationship exists between perioperative myocardial ischemia (ST segment depression greater than or equal to 0.1 mV) and postoperative myocardial ...

Monitoring for myocardial ischemia
Best Practice & Research Clinical Anaesthesiology, 2005During the last 20 years, studies using continuous perioperative electrocardiogram (ECG) monitoring in patients at high risk for postoperative cardiac complications have revolutionized our understanding of the pathophysiology, circumstances, timing and possible prevention of perioperative ischemia and postoperative cardiac morbidity and mortality.

Mechanisms of myocardial ischemia
The American Journal of Cardiology, 1992Traditionally, myocardial ischemia has been viewed as an imbalance in the supply and demand of myocardial oxygen. Stable angina is usually considered to involve a fixed lesion, whereas unstable angina involves a fixed lesion as well as such components as platelet aggregation, thrombotic processes, and vasospasm.

Mechanisms of myocardial ischemia
The Journal of Cardiovascular Nursing, 1989Myocardial ischemia occurs as a result of an imbalance between tissue oxygen supply and demand. The clinical correlates of the syndrome include classic unstable and Prinzmetal variant angina. Although controversial, it has been postulated that the pathogenesis of unstable angina involves a combination of (1) fixed atherosclerotic coronary artery ...

Myocardial Ischemia Manifestation
Archives of Neurology, 1982To the Editor.— In the article "Bregmatic Headache as a Manifestation of Myocardial Ischemia" (Archives1982;39:130), Drs Lefkowitz and Biller describe an interesting and well-known but uncommon clinical symptom of sudden, severe, "explosive" evanescent cranial pain.
