Cardiac function is a research area that focuses on understanding how the heart functions in terms of pumping blood throughout the body. This field examines the mechanical, electrical, and metabolic processes that regulate the heart's ability to contract and relax effectively. Researchers in this area study various aspects of cardiac function, including heart rate, stroke volume, cardiac output, and heart muscle contractility. Understanding cardiac function is essential for diagnosing and treating various cardiovascular diseases, such as heart failure, arrhythmias, and coronary artery disease. It also plays a crucial role in developing new therapies and interventions to improve heart health and overall cardiovascular function.
