Properly treated unstable angina and non-Q wave myocardial infarction have low hospital mortality, but untreated, mortality is high. Symptoms and labs usually suffice for diagnosis. Abnormal physical findings are rarely helpful and often absent. Careful surveillance and management substantially reduce long-term risks.

Cardiovascular Drugs and Therapy, 1994
The term unstable angina encompasses heterogeneous clinical syndromes. Fissuring of an atherosclerotic coronary artery plaque with superimposed platelet deposition, with or without additional thrombus formation, is invariably responsible for a prolonged episode of angina at rest, increasing frequency of angina at rest, or with minimal exertion of less ...

What's “Unstable” in Unstable Angina?
Psychosomatics, 2004The role of emotional distress (e.g., anger, depression, and anxiety) in anginal chest discomfort (ACD) may have been underestimated. The authors review the empirical studies in this area, which are inconsistent with the standard theory on the ischemia-angina relationship; summarize the substantial evidence indicating a strong and consistent cross ...

Survey of Anesthesiology, 2000
Unstable angina accounts for more than 1 million hospital admissions annually1; 6 to 8 percent of patients with this condition have nonfatal myocardial infarction or die within the first year after diagnosis.2,3 Various definitions of unstable angina have been proposed, but in 1989, Braunwald devised a classification system to ensure uniformity of ...

Australian and New Zealand Journal of Surgery, 1977
A series of 84 patients with unstable angina, treated surgically by grafting procedures between October 1970 and September 1976, have been reviewed. The study indicates that extensive coronary artery disease is common in these patients, and suggests that operation may favourably influence mortality, both immediate and delayed, but does not reduce the ...

Angiography in unstable angina
The American Journal of Cardiology, 1991Within the last decade, it has been appreciated that the acute coronary syndromes of unstable angina, non-Q-wave, and Q-wave myocardial infarction often share a common pathogenesis based on plaque disruption and thrombosis. Such "acute" lesions frequently have a characteristic angiographic appearance with sharp overhanging edges, irregular borders, and

Unstable angina and thrombolysis
Chest, 1990Unstable angina occurs in a heterogeneous population of patients. In the subset of patients with recent rest angina, both angiographic and angioscopic studies have suggested that coronary artery thrombus is often present and serves as a predictor of subsequent adverse clinical events, including recurrent angina, myocardial infarction, the need for ...

The hallmark of unstable angina is its unpredictability. The symptoms, which occur without provocation, sometimes stabilize or resolve but sometimes progress to myocardial infarction or sudden death. This pattern contrasts with that of stable angina.

American Heart Journal, 1976
Unstable angina is a syndrome which comprises a spectrum of symptomatic manifestations of coronary artery disease which lies between stable angina pectoris and acute myocardial infarction. Patients fall into three groups: angina of recent onset (4 weeks), angina of changing pattern, and angina occurring at rest (longer than 15 minutes).

Treatment of both stable and unstable angina depends on initially defining the pathophysiological mechanisms. The goal of treatment is to prevent the development of angina pectoris and possibly also to improve the prognosis. beta-blockade is effective in treating effort-related angina, as are calcium antagonists, which are also effective in treating ...
