Cardiomyocyte function refers to the function of the cells that make up the heart muscle, known as cardiomyocytes. These cells are responsible for the contraction and relaxation of the heart, which allows it to pump blood throughout the body. Research in this area focuses on understanding the mechanisms underlying the normal function of cardiomyocytes, as well as how dysfunction in these cells can lead to heart diseases such as heart failure and arrhythmias. This research may involve studying the electrical and mechanical properties of cardiomyocytes, as well as the signaling pathways that regulate their function. Ultimately, this research aims to develop new treatments for cardiovascular diseases by targeting specific pathways or mechanisms that are disrupted in diseased cardiomyocytes.
