Stress-Echokardiography - Assessment of myocardial blood flow

The stress test shows whether a circulatory disorder - usually caused by a constriction of the blood vessels - is present.

A stress echocardiography can check if a particular section is still vital or pumping poorly (to differentiate from scar tissue). The stress echocardiography is applied mainly within the framework of ischemia diagnosis. A wide variety of imaging, measurement and analysis techniques are available in stress echocardiography and allow for a highly differentiated assessment of complaints. When test results do not give entirely clear indications is when additional methods in echocardiography can be administered during the examination. Basically, three types of stress tests are used to find answers for different issues.
 
Ischemic cascade
There are three basic processes in stress echocardiography:
  • stress echocardiography with ergometric/bicycle stress
  • stress echocardiography with dobutamine (medicinal / pharmacological stress)
  • stress echocardiography with a widening of blood vessels; vasodilator stress (vasodilation with adenosine)

 

Modern analytical methods help the examiner in the diagnosis.
