Area of Science:

  • Cardiology
  • Medical Imaging

Background:

  • Stress echocardiography has transitioned from research to clinical practice for coronary artery disease (CAD) diagnosis.
  • It is recognized for its safety, versatility, and clinical accuracy.

Purpose of the Study:

  • To evaluate the role and applications of stress echocardiography in managing coronary artery disease.
  • To compare stress echocardiography with radionuclide perfusion imaging.

Main Methods:

  • Stress echocardiography involves assessing cardiac function under stress.
  • Validation against radionuclide perfusion imaging was performed.
  • Low-dose dobutamine regimens are used for assessing contractile reserve and viability in patients with impaired left ventricular function and ischemic heart disease (IHD).

Main Results:

  • Stress echocardiography is clinically accurate and validated against radionuclide perfusion imaging.
  • Echocardiography offers cost and convenience advantages, though perfusion imaging may have higher sensitivity in single-vessel disease.
  • There is a learning curve associated with stress echocardiography acquisition and interpretation.

Conclusions:

  • Stress echocardiography is a valuable, cost-effective adjunct to exercise ECG for CAD management.
  • Its role is expanding, particularly with advancements in echocardiography technology.
  • Local availability and demand influence the choice between stress echocardiography and perfusion imaging.
