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

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.

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 ...

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).

Unstable angina is a common condition that presents a challenge to physicians because of its complex pathophysiology, and because of the high incidence of associated death and myocardial infarction. This article summarizes key strategies that can be employed in managing unstable angina and describes their interaction with the mechanisms that underpin ...

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 ...

Pharmacotherapy of Unstable Angina
The Journal of Clinical Pharmacology, 1992All patients with unstable angina should be admitted to a coronary or an intensive care unit. There should be an attempt to classify the patient according to the proposed Braunwald nomenclature. If the patient has a secondary cause for unstable angina (e.g., tachyarrhythmia, heart failure, fever, thyrotoxicosis, severe hypertension, hypoxia, unusual ...

MAJOR presentations of coronary artery disease include sudden death, myocardial infarction, stable angina, unstable angina, and miscellaneous syndromes such as arrhythmias and left ventricular failure. While the prevalence of unstable angina is relatively low compared with other coronary disease syndromes, the potential for prevention of infarction and

Pathophysiology of Unstable Angina
Cardiology Clinics, 1991This article discusses the heterogeneous clinical spectrum of atherosclerotic coronary artery disease. The clinical manifestations and pathophysiology of unstable angina as well as atherosclerotic coronary stenosis, mechanisms of plaque fissure, factors that contribute to coronary artery obstruction, and mechanisms of platelet aggregation and ...

Thrombolysis in refractory unstable angina
The American Journal of Cardiology, 1991Multiple drug therapy, including nitrates, beta blockers, calcium antagonists, aspirin, and heparin, has been advocated as effective in the treatment of unstable angina, a syndrome with a multifactorial pathogenesis. Recently, plaque rupture and thrombosis have been demonstrated as the most important pathogenetic mechanisms.
