Noun1.cardiac muscle - the muscle tissue of the heartcardiac muscle - the muscle tissue of the heart; adapted to continued rhythmic contraction
muscular tissue, muscle - animal tissue consisting predominantly of contractile cells
ticker, heart, pump - the hollow muscular organ located behind the sternum and between the lungs; its rhythmic contractions move the blood through the body; "he stood still, his heart thumping wildly"
cardiac pacemaker, SA node, sinoatrial node, pacemaker - a specialized bit of heart tissue that controls the heartbeat
papillary muscle - any of several muscles associated with the atrioventricular valves; "the papillary muscles contract during systole to prevent regurgitation of blood into the atria"
atrioventricular bundle, atrioventricular trunk, bundle of His, truncus atrioventricularis - a bundle of modified heart muscle that transmits the cardiac impulse from the atrioventricular node to the ventricles causing them to contract
atrioventricular node - a node of specialized heart muscle located in the septal wall of the right atrium; receives impulses from the sinoatrial node and transmits them to atrioventricular bundle
myocardium - the middle muscular layer of the heart wall
Purkinje fiber - a specialized cardiac muscle fiber that is part of the Purkinje network
Purkinje network, Purkinje's system, Purkinje's tissue - a network of Purkinje fibers that carry the cardiac impulse from the atrioventricular node to the ventricles of the heart and causes them to contract

In the present study, we hypothesized that TLR stimulation by a DAMP such as HSP60 induced an inflammatory response and cardiomyocyte hypertrophy, and that these outcomes were abrogated after treatment with a small interfering RNA (siRNA) against CaMKII delta B (CaMKII[delta]B).
One obvious question is whether this is cardiomyocyte specific or if it could be useful in making neurons of pancreatic islet cells where defects can lead to diabetes.
In the second phase, we believe the microRNAs help with cardiomyocyte proliferation," said Wang.
Cardiomyocyte plating and maintenance media were obtained from Cellular Dynamics International (CDI, Madison, WI).
This combination resulted in a more than 50-fold increase in the efficiency of cardiac reprogramming compared to GMT alone and produced iCMs with mature cardiomyocyte marker expression, robust calcium oscillation, and spontaneous beating [18].
Interestingly, the Hippo pathway participates in diverse physiological and pathological processes in the heart spanning heart development, apoptosis, hypertrophy, autophagy, angiogenesis, and cardiomyocyte regeneration [7].
Non-cardiomyocyte cells like fibroblasts, endothelial cells, smooth muscle cell and immune cells and lack of evidence of cytokinesis due to rigid sarcomeric membrane seem to be confounder how good the regeneration rate could be estimated.13 Interestingly, various methods using a transgenic mouse model with beta-galactosidase, 14C labeling of cardiomyocyte nuclei and multi-isotope imaging mass spectrometry showed a renewal rate not more than 1-2% per year.6,8,9 However, to what extent these rates might increase after injury is not clear.
Myocardium was stained with Masson's trichrome (Figures 2(a) and 2(b) and H&E (Figure 2(c)) to identify cardiac fibrosis and cardiomyocyte morphology, respectively, after CLP.
The oxidative stress outburst in the first minutes of myocardial reperfusion causes myocardial injury and cardiomyocyte death through several different mechanisms which provide therapeutic targets at the onset of myocardial reperfusion [4].
Many experimental and clinical studies reveal that the expression of miR is highly altered in various cardiovascular problems and their alterations are linked with modulation of activity and expression of key components of cardiomyocyte growth, survival, and death.
