Cardiovascular magnetic resonance (CMR) offers a sensitive method for assessing subtle changes in myocardial function. This imaging technique accurately quantifies cardiac structure and function, aiding in early detection of cardiac dysfunction.

Area of Science:

  • Cardiovascular imaging
  • Cardiac mechanics
  • Biomedical engineering

Background:

  • Coronary artery disease-induced heart failure presents significant morbidity and poor prognosis.
  • Understanding myocardial contraction mechanics is crucial for diagnosing and predicting heart disease progression.
  • Current methods lack sensitivity for detecting subtle, early-stage cardiac dysfunction.

Purpose of the Study:

  • To highlight the role of imaging, specifically cardiovascular magnetic resonance (CMR), in studying cardiac morphology, function, and flow.
  • To demonstrate CMR's capability in assessing the interplay between cardiac structure and blood flow.
  • To explore the integration of imaging with biomechanical simulations for subject-specific analysis.

Main Methods:

  • Utilized cardiovascular magnetic resonance (CMR) for high-quality imaging of cardiac structure and function.
