The classification of unstable angina has, until now, been based on simple clinical descriptors, such as whether the ischaemic pain is on exertion and accelerating, or whether it occurs at rest,1 and whether or not ischaemia persists despite vigorous anti-ischaemic Nov 11, 2000 · Pathophysiology of unstable angina. Thrombus has also been observed in the coronary arteries at coronary angioscopy in patients undergoing cardiac surgery for unstable angina pectoris. 1 Braunwald E. " Background: Autopsy studies have shown that unstable angina and infarction are related to plaque instability and involve events such as fissure or rupture of the fibrous cap, thrombosis and inflammation. Braunwald's classification was applied at admission: The outcomes of interest during hospitalization were coronary angiographic findings, short- term prognoses, and the treatment selected. Stable angina, often referred to as angina of effort, and its principal cause, reduction of the lumen of epicardial coronary arteries, have been recognized for >2 centuries. Unstable angina belongs to the spectrum of clinical presentations referred to collectively as acute coronary syndromes (ACSs), which range from ST-segment elevation myocardial infarction (STEMI) to non-STEMI (NSTEMI). The classification has been validated clinically ( 7 ), has been shown to correlate with coronary angiographic findings ( 8 ), and has now been updated to include troponin levels ( Table Jul 1, 2022 · The term "unstable angina pectoris" has been used since 1971. According to the revised MI definitions, patients with ischemic symptoms but with only a minor rise and fall in any biomar … Unstable Angina and Non-ST-Elevation Myocardial Infarction Eugene Braunwald, MD Abstract—Unstable angina/non-ST-elevation myocardial infarction (UA/NSTEMI) is a common but heterogeneous disorder with patients exhibiting widely varying risks. The Braunwald classification (5) appeared to be an appropriate instrument for identifying groups of patients with different levels of risk at 6 months (6 Jun 4, 2016 · The unstable angina classification developed by Braunwald is based on the severity of symptoms, their clinical context, and the intensity of medical treatment. 6 Recent onset of angina (within 48 h), secondary angina and post-myocardial infarction UNSTABLE ANGINA Both pathologic13•14 and angiographic&-9 • 1:>-~ 9 studies have suggested the presence of coronary artery throm-bus in patients with unstable angina. "Correlation of Braunwald's clinical classification of unstable angina pectoris with angiographic extent of disease, lesion morphology and intra-luminal thrombus". This system was then Home | AHA/ASA Journals Jan 10, 2000 · Table 1.
