Cardiac muscle cell fatigue. There are two types of cells within the heart: the cardiomyocytes and the cardiac pacemaker cells. Cardiomyocytes make up the atria (the chambers in which blood enters the heart) and the ventricles (the chambers where blood is collected and pumped out of the heart). These cells must be able to shorten and lengthen their fibers and the fibers must be flexible enough to stretch. These functions are critical to the proper form during the beating of the heart. Cardiac pacemaker cells carry the impulses that are responsible for the beating of the heart. They are distributed throughout the heart
Cardiac neural crest cells observed when GATA6 was inactivated within vascular smooth muscle cells. GATA6 in combination with Wnt (Wnt2-GATA6) plays a role in the development of the posterior pole of the heart (the inflow tract). There is interest amongst researchers as to whether CNCCs can be used to repair human heart tissue. Heart attacks in humans are common and their rate of mortality is high. There are emergency treatments that hospitals can administer, such as angioplasty or surgery, but after that patients will likely be on medication for the long term and are more susceptible to heart attacks in the future.
