Intravascular Ultrasound Observation of the Mechanism of No-Reflow Phenomenon in Acute Myocardial Infarction

Intravascular Ultrasound Observation of the Mechanism of No-Reflow Phenomenon in Acute Myocardial Infarction

OBJECTIVE To study the mechanism of the no-reflow phenomenon using coronary angiography (CAG) and intravascular ultrasound (IVUS). METHODS A total of 120 patients with acute myocardial infarction (AMI) who successfully underwent indwelling intracoronary stent placement by percutaneous coronary intervention (PCI). All patients underwent pre- and post-PCI CAG and pre-IVUS. No-reflow was defined...

Intravascular ultrasound in the diagnosis of the no-reflow phenomenon after primary angioplasty for myocardial infarction.

A 73 year old man was admitted with haematemesis and was found to have a pangastritis. Three days later he developed central chest pain, and ECG changes indicated an acute anterior myocardial infarction. In view of his recent haematemesis we performed emergency coronary angiography, which showed proximal occlusion of the left anterior descending (LAD) artery (TIMI 0 flow), with normal circumfle...

Hyperglycemia and no-reflow phenomenon in acute myocardial infarction.

Phenomenon in Acute Myocardial Infarction Dr. Iwakura and colleagues in a recent issue of the Journal (1) conclude that, from a retrospective analysis of 146 patients, hyperglycemia might be associated with impaired microvascular function after acute myocardial infarction. The investigators describe an independent relation between elevated blood glucose levels on admission and no-reflow phenome...

No-reflow phenomenon: Achilles' heel of primary coronary angioplasty in acute myocardial infarction.

Association between hyperglycemia and the no-reflow phenomenon in patients with acute myocardial infarction.

OBJECTIVES We investigated the association between hyperglycemia and the no-reflow phenomenon in patients with acute myocardial infarction (AMI). BACKGROUND Hyperglycemia is associated with increased risks of heart failure, cardiogenic shock, and death after AMI, but its underlying mechanism remains unknown. METHODS A total of 146 consecutive patients with a first AMI were studied by intrac...
