Heart function research involves studying the structure and function of the heart, as well as the processes and mechanisms by which the heart pumps blood throughout the body. This research area focuses on understanding how the heart works, how it can be affected by various diseases or conditions, and how it can be treated or managed to ensure optimal cardiovascular health. Researchers may study topics such as heart rate, blood pressure, cardiac output, and the role of hormones and neurotransmitters in regulating heart function. This research is crucial for advancing our understanding of cardiovascular health and developing new treatments for heart disease.
