Recovery of regional myocardial function and myocardial oedema following reperfused acute myocardial infarction

Recovery of regional myocardial function and myocardial oedema following reperfused acute myocardial infarction

We investigated the relationship between myocardial oedema and recovery of regional myocardial function in patients with acute reperfused myocardial infarction (MI). Early after acute MI, oedema in the peri-infarct zone, as delineated by T2 weighted (T2w) cardiovascular magnetic resonance (CMR) imaging, demonstrated significantly reduced strain as compared to remote myocardium. The recovery of ...

Rapid Diagnosis of Acute Myocardial Infarction

To improve the specificity of biochemical markers of myocardial infarction (MI) a method to measure cardiac troponin-I (CTn-I) was developed. CTn-I is a protein unique to cardiac muscle and is released after MI. Consecutive 150 patients admitted to the coronary care unit was studied. Value of CTn-I was determined in all samples. CTn-I concentration in the MI patients group was increased com...

Myocardial Hemorrhage After Acute Reperfused ST-Segment–Elevation Myocardial Infarction

Quantification of Regional Myocardial Function following Acute Myocardial Infarction by Ultrasonic Strain Rate and Strain Imaging

Objectives: The rapid diagnosis and early risk stratification of patients presenting with acute myocardial infarction (AMI) is important. In experimental setting ultrasonic strain rate (SR) and strain (S) have been shown to identify changes in deformation predictive of ischemia. We sought to evaluate and compare regional myocardial function at “the risk zone” (ARZ) supplied by the culprit coron...

Recovery of Regional Myocardial Function After Coronary Angioplast in Acute Myocardial Infarction

Background The objective of the study was to determine the coronary vasodilatory reserve in reperfused myocardium in patients with acute myocardial infarction and its relation to regional myocardial function. Methods and Results The study population consisted of 22 patients with acute myocardial infarction who underwent successful coronary angioplasty. The vasodilatory reserve in the reperfused...
