The myocardium is the muscular tissue of the heart, responsible for contracting and pumping blood throughout the body. Research in this area focuses on understanding the structure, function, and regulation of the myocardium, as well as how various diseases and conditions can affect its health and performance. Studies may examine topics such as cardiac physiology, myocardial infarction, heart failure, myocarditis, and cardiomyopathies. Researchers in this field often utilize techniques such as imaging, electrophysiology, molecular biology, and genetics to study the myocardium and develop new treatments for cardiac disorders.
