UNSTABLE ANGINA Coronary angioplasty for early postinfarction unstable angina

Coronary angioplasty was performed in 53 patients in whom unstable angina had reoccurred after 48 hr and within 30 days after sustained myocardial infarction. Single-vessel disease was present in 64% of the patients and multivessel disease in 36%. The preceding myocardial infarction had been small to moderate in size in the majority of the patients. The left ventricular ejection fraction was mo...

Aspirin for unstable angina?

Unstable angina.

Unstable angina has only been recognized as a distinct entity for about 50 years. The term is used to describe a symptom complex that is neither stable angina pectoris nor acute myocardial infarction. There are a number of other terms used to describe essentially the same symptom complex; these include pre-infarction angina, crescendo angina, intermediate coronary syndrome and threatening infar...

Unstable Angina

Identification of a characteristic morphology of a coronary stenosis likely to result in myocardial infarction would facilitate the prospective evaluation of infarct prevention strategies and identification of high-risk patients. We postulated that coronary lesions associated with recent myocardial infarction or unstable angina would have an angiographic morphology suggesting disruption of an a...

Emergency revascularization for unstable angina.

Emergency revascularization for unstable angina (defined according to criteria of the National Cooperative Study Group) was performed in 100 consecutive patients. The mean interval from onset of pain to operation was one day. Nineteen patients had single-vessel narrowing of greater than 70% of lumen diameter, 32 double-vessel obstruction and 49 triple-vessel disease. Fourteen of these patients ...
