To clarify the role of coronary spasm or dynamic coronary obstruction in the development of acute myocardial infarction (AMI) with spontaneous recanalization (SR), symptoms in 296 patients with AMI admitted within 24 h after the onset of chest pain w

Increases in regional myocardial blood flow (Qm) developing soon after myocardial infarction may minimize myocardial necrosis. To test this hypothesis, Qm in the area surrounding an acutely occluded coronary artery was determined successively over 4

A thin myocardial layer adjacent to the epicardium (epicardial rim) often survives after transmural myocardial infarction. Regional myocardial blood flow (Qm) at this rim may be high enough to maintain myocardial viability during coronary occlusion.

The sum of ST-segment elevation (sigma ST on V2-4) was measured to evaluate ST-segment re-elevation during early convalescence in 57 patients with acute myocardial infarction. Following rapid ST-segment elevation resolution during the first 12 h, sig

The clinical features of acute myocardial infarction patients in whom abnormal Q wave disappeared were analyzed. Of 201 patients, 40 (20%) (Group A) showed disappearance of Q wave in serial electrocardiograms. Regional ejection fraction of the infarc

In order to study the effects of residual stenosis on myocardial salvage, we created 99% coronary stenosis with or without contrast washout delay at reperfusion in six groups of dogs. In Group A (n=8), the artery was occluded for 1h before being full

We studied whether basic fibroblast growth factor (bFGF) might increase regional Myocardial blood flow (Qm) at the infarcted myocardium. In eight dogs, bFGF 300 μg was injected into the myocardium supplied by the left anterior descending coronary ar

In our single-heart model, half permanently occluded and half reperfused, reperfusion 12 hours after coronary artery occlusion salvaged myocardium in dogs. This finding may be one of the reasons why late reperfusion is beneficial in patients with acu

Hyperemia, which occurs immediately after coronary reperfusion, injures the myocardium. Mild coronary stenosis may mitigate this hyperemia and thus may augment myocardial salvage. To test this hypothesis, left anterior descending coronary arteries of

We studied the importance of reflow after reperfusion for myocardial salvage. In 19 open-chest dogs, the left anterior descending coronary artery was occluded for 3h and then reperfused. Non-radioactive colored microspheres were injected into the lef
