myocardium

the muscular tissue of the heart

Myocardium

 

the muscular layer that constitutes most of the heart. It consists of striated muscle tissue made up of a dense aggregation of muscle cells. A functional characteristic of the myocardium is rhythmic, automatic contraction alternating with relaxation, which continues without interruption throughout the life of the organism.

The researchers found that the prevalence of myocardial infarction was 15.3 percent among 22,651 patients.
Four days after admission, we performed myocardial perfusion and fatty acid metabolism assessment with thallium-201 and iodine-123-betamethyl -p-iodophenyl-pentadecanoic acid (I-123-BMIPP).
Currently aspirin is commonly used in clinic, but it is limited in clinical application because of its slow onset and high variability.9 In this study, 132 patients with acute myocardial infarction were taken as research subjects to study the clinical efficacy of aspirin combined with clopidogrel after PCI.
In conclusion, we are confident that cTnI or CKMB with ECG carry equal predictive power to detect clinically significant myocardial injury following CABG according to recommendations that CKMB carries additional association with renal dysfunction which needs to be evaluated further.
Myocardial bridging is a congenital anomaly, where a segment of an epicardial coronary artery is undercover of myocardial fibres for a variable distance and the underlying arterial segment is described as a mural coronary artery or a tunnelled artery.
It has been shown that diabetes can not only aggravate myocardial IRI but also weaken or even eliminate the cardioprotective effects of many interventions including IPC.[5],[6],[7],[8],[9] Much efforts have been made, but the detailed mechanisms that diabetes affects the severity of myocardial IRI and efficacy of cardioprotective interventions are not well elucidated.
For the sake of immediate reperfusion treatment, it is usual practice to differentiate MI with ST elevation in two contiguous leads, as ST elevation myocardial infarction (STEMI), and MI without ST elevation, usually designated as non-ST elevation myocardial infarction (NSTEMI).
Next observations, during which myocardial infarction was diagnosed by the means of ECG, were performed by H.E.B.
Digital photographs were processed in open-source and free imaging software GIMP (GNU Image Manipulation Program, The GIMP team, GIMP 2.8.10, www.gimp.org) in order to create colored 'masks' of certain tissue areas (red for myocardial layer, black for perivascular fat tissue, and green for non-perivascular fat tissue) (Figs.
In myocardial bridging, a coronary artery that runs typically on the epicardium develops a transient intramyocardial course.
Eight weeks after diabetic induction, myocardial IR operation was established as previously [12].
