Ischemia at a distance after acute myocardial infarction: a cause of early postinfarction angina.

Long-Term Prognosis of Patients With Early Post-Infarction Angina

“…5,7,12,20 We did not find a higher probability of death and cardiac death in patients with EPA. These findings are similar to those reported by Galjee et al 7 (after a 4 year follow-up period) and Fioretti et al 12 (after a 1 year follow-up period), but different from the findings presented by other authors, who found a higher 1-year mortality in patients with EPA.…”

Early postinfarction ischemia: clinical, angiographic, and prognostic significance.

“…Sixty-nine patients died in hospital, 37 within 24 hr of admission. Among the 32 patients who died after 24 hr, spontaneous ischemia had been present in 16. Coronary arteriography was performed before hospital discharge in 449 survivors; excluded were 23 patients with severe congestive heart failure, 23 with noncardiac contraindications to cardiac catheterization, and 67 who were reluctant to accept early angiography. These 449 patients represent 80% of the survivors and form the study population.…”

Echocardiographic detection of infarct-localized asynergy and remote asynergy during acute myocardial infarction: correlation with the extent of angiographic coronary disease.

“…In experimental infarction in dogs, as little as 20% transmural necrosis can produce the findings of complete akinesis, and additional necrosis results in little worsening of the asynergy. 5 Reperfusion of an ischemic segment results in an even greater disparity between wall motion and histologic necrosis.62 A disparity between wall motion and extent of infarction has also been described using contrast ventriculography and histopathologic examination.7' 63. 6 Even in completed infarctions, echocardiographic findings of akinesis cannot exclude the presence of some viable myocardium.…”
