41. Kloner et al . reported that a pathological change in the myocardium was not demonstrated in the stunned myocardium . 42. Further, it is possible to taking this momentum back to Purkinje fibers along the vessels of the myocardium . 43. In mouse, deletion of this homologous gene causes congenital heart disorder known as noncompaction of left ventricular myocardium . 44. Most published surgical methods of HT necessarily divide the Vagus nerve and thus amputate parasympathetic control of the myocardium . 45. Genetic modifications which lend endurance and longevity to stem cells placed in damaged myocardium are being investigated as well. 46. When the myocardium is stretched, the ST2 gene is upregulated, increasing the concentration of circulating soluble ST2. 47. The myocardium thickens and secretes a thick layer of rich extracellular matrix containing hyaluronic acid which separates the endothelium. 48. In vivo inflow within the myocardium is probably best described by influence of the vagus nerve and spinal accessory ganglia. 49. Cardiac output will then increase according to the Frank Starling graph . ( The above is true of healthy myocardium . 50. Recently, the intentional destruction of myocardium by alcohol septal ablation has led to the identification of additional potential markers.
