Cardiac myocytes are muscle cells found in the heart that are responsible for generating the force needed to pump blood throughout the body. These specialized cells have unique characteristics that allow them to contract rhythmically and efficiently to maintain the heart's function. Research in this area focuses on understanding the cellular and molecular mechanisms underlying the contraction and relaxation of cardiac myocytes, as well as how these processes are regulated in health and disease. Studies in cardiac myocytes aim to improve our understanding of various heart conditions, such as arrhythmias, heart failure, and other cardiovascular diseases, and ultimately develop novel therapeutic strategies to treat these conditions.
