Early cardiac research focused on whole-heart functions like pressure and flow. Later studies integrated cellular and molecular mechanisms for a comprehensive understanding of cardiac performance.

Area of Science:

  • Cardiology
  • Biomedical Engineering
  • Systems Biology

Background:

  • Historically, cardiac research concentrated on macroscale parameters like pressures, blood flow, and electrical activity.
  • Early studies utilized engineering science, simulation, and modeling to understand whole-heart function and interactions.
  • Key research areas included 3D imaging, ventricular structure, cardiovascular flow, and electrical propagation.

Purpose of the Study:

  • To shift focus from macroscale cardiac function to the underlying cellular and intracellular control mechanisms.
  • To integrate organ-level studies with genetic, molecular, and cellular characteristics for a deeper understanding.
  • To emphasize the importance of cellular communication and signaling in cardiac performance.

Main Methods:
