  • With the array of approaches that are currently being tested and the questions that they raise, it becomes increasingly clear that the regeneration of adult myocardium will require the integration of numerous factors that govern cardiac tissue biology in normal and pathological conditions. (hindawi.com)
  • Moreover, a regenerated tissue band, which would integrate functionally with the surviving myocardium, was observed only in few cases [ 2 ]. (hindawi.com)
  • Potentiation of myocardial salvage by tissue type plasminogen activator in combination with a thromboxane synthetase inhibitor in ischemic cat myocardium. (ahajournals.org)
  • velocity
  • For assessing subclinical myocardial function, the myocardial reflectivity (integrated backscatter intensity) of the ventricular septum (IBI-sp) and posterior wall (IBI-pw), and the systolic (Sa) and diastolic (Ea) velocity at the mitral annulus were obtained. (ahajournals.org)
  • Therefore, the aim of this study was to determine the roles of echocardiographic measures of right ventricular (RV) function, namely, Doppler tissue imaging-derived RV index of myocardial performance (RIMP), RV basal free wall systolic excursion velocity (RV S'), and tricuspid annular plane systolic excursion, in differentiating ABS from obstructive LAD disease.

  • M-mode TDI parameters were recorded from a short-axis view for measurement of endocardial and epicardial systolic velocities and subsequent myocardial velocity gradient (MVG) within the posterior wall. (vin.com)

  • We compared two quantitative software packages, quantitative gated SPECT (QGS) and Emory cardiac toolbox (ECTb), with tissue Doppler imaging (TDI) as the conventional method for the evaluation of left ventricular mechanical dyssynchrony. (biomedsearch.com)
  • LVEF
  • The left ventricle ejection fraction (LVEF), shortening fraction (SF), and the UTC indices: corrected coefficient of integrated backscatter (IBS) (tissue IBS intensity/ phantom IBS intensity) (CC-IBS) and the cyclic variation magnitude of this intensity curve (MCV) were measured.

  • In conclusion: UTC was able to early identify the DXR myocardial lesion when compared to LVEF, showing good accuracy to detect the initial collagen deposition in this experimental animal model. (springermedizin.de)
  • apoptosis
  • The choice of cell population for myocardial regeneration should be based on the knowledge of stem cell biology and the mechanisms that regulate and control cardiac progenitor proliferation, apoptosis, and differentiation in the normal and pathological conditions [ 3 ]. (hindawi.com)
  • Circulation
  • Nanosecond pulse electric fields applied to the cardiac tissue are considered to be a possible tool for treatment of arrhythmias or to improve blood circulation inside the myocardial tissue. (rjor.ro)

  • subcutaneous
  • 14 Subcutaneous adipose tissue is considered the best choice for the study of long-term fatty acid intake, mainly because of the slow turnover 15,16 and its lack of response to acute disease. (ahajournals.org)
  • Regeneration
  • A desirable candidate cell for cardiac tissue engineering and regeneration would be autologous, capable of differentiation into all the cardiac cell types and of functional integration, and resistant to malignant transformation. (hindawi.com)
  • correlation
  • However, arrhythmogenic mechanism of such substrate is not well defined, because its investigation requires quantitative, complete and detailed knowledge on the correlation of local abnormality in phenomenal electrical function and inherent tissue property during normal sinus rhythm.
