Widespread myocardial inflammation and infarct-related artery patency.
BACKGROUND Diffuse coronary vascular inflammation is associated with acute coronary syndromes. However, it is unknown whether inflammation also occurs within the myocardium. Therefore, this study was aimed at assessing the presence of activated cells in unaffected remote myocardium of patients with acute myocardial infarction (AMI), in comparison to the peri-infarct region from the same cases, ...
متن کاملMonocytes: protagonists of infarct inflammation and repair after myocardial infarction.
Myocardial infarction (MI) is the most frequent cause of heart failure, which is an incapacitating disease with high prevalence and broad socioeconomic impact. In 2008 in the United States, 5.7 million people suffered from heart failure, and more than 287 000 people died.1 Timely revascularization of ischemic myocardium reduces acute infarct mortality, and current standard therapy with blockers...
متن کاملMyocardial Infarct Quantification
Radionuclide techniques for sizing acute myocardial infarction have been hampered by the intrinsic limitations of the scintillation camera. Emission computed tomography can overcome these limitations. Single photon emission computed tomograms of the distribution of technetium-99m pyrophosphate in acute anterior and posterior infarcts were obtained in 16 dogs after death. Tomograms were also obt...
متن کاملEnzymatic profile of myocardial infarct.
T he causal relationship between the rise in activity of certain enzymes in the serum and the occurrence of damage to the myocardium has been established without question. Experiments and histochemical investigations have shown that infarcted heart muscle is rapidly depleted of various enzymes, and that these enzymes appear in an active form in the blood that drains from the infarcted myocardiu...
متن کاملRelationship Between Myocardial Infarct Size
We compared myocardial infarct size produced by permanent occlusion of the middle left anterior descending (LAD) or circumflex (LCx) coronary artery in the anesthetized dog. The dogs were killed 3-10 days later, and the occluded coronary bed was visualized by postmortem arteriography. The outlines of the infarct and occluded bed were marked on tracings of weighed left ventricular (LV) rings and...
