Dissolution of angiographically detected intracoronary thrombus for unstable angina pectoris after aspirin therapy

Aspirin for unstable angina?

Pathology of stable and unstable angina pectoris.

The clinical and pathological data from 46 patients who died during or shortly after coronary bypass surgery and one patient who died shortly after angiography were studied. Each patient was placed into one of three clinical categories of angina pectoris. Twelve were classified as having unstable angina pectoris, 20 as stable severe angina, and 15 as stable moderate angina. No significant diffe...

Circulating platelet products in unstable angina pectoris.

In 19 patients with unstable angina pectoris at rest, plasma levels of the platelet-derived proteins beta-thromboglobulin and platelet factor 4 were significantly elevated in blood samples obtained during or within 4 hours after episodes of angina, but were usually normal during quiescent intervals. Plasma levels of the arachidonic acid metabolite thromboxane B2 were less clearly related to ang...

Thallium-201 scintigraphy in unstable angina pectoris.

Thallium-201 scintigraphy was performed during the pain free period in 98 patients with unstable angina. Scintiscans were positive in 39 patients, questionable in 27 patients and normal in 32 patients. Eighty-one patients responded favorably to treatment (group I). Seventeen patients had complicated courses (group II) and despite maximal treatment with propranolol either developed infarction (s...

The role of intracoronary thrombus in unstable angina: angiographic assessment and thrombolytic therapy during ongoing anginal attacks.

Intracoronary thrombus is regarded as a potentially important factor in the etiology of unstable angina, but the incidence of intracoronary thrombus in unstable angina has not been clearly defined. To determine the occurrence of intracoronary thrombus during ongoing angina pectoris, coronary angiography was performed during spontaneous ischemic attacks in 37 patients with prolonged rest angina....
