[How to do a stress echocardiography?]

Area of Science:

• Cardiology
• Diagnostic Imaging

Background:

• Stress echocardiography (SE) is a key functional imaging tool.
• It evaluates cardiac performance under induced stress conditions.

Purpose of the Study:

• To outline the indications, methods, and limitations of stress echocardiography.
• To highlight its role in diagnosing coronary artery disease (CAD) and assessing structural heart disease.

Main Methods:

• Utilizes dynamic (exercise) or pharmacological (dobutamine, adenosine) stress induction.
• Exercise stress involves treadmills or bicycles; pharmacological stress is used for non-exercising patients or viability assessment.

Main Results:

• SE is primarily indicated for detecting myocardial ischemia in CAD.
• It is also valuable for evaluating valvular disease and hypertrophic obstructive cardiomyopathy.
• Pharmacological stress, particularly dobutamine, aids in assessing myocardial viability.

Conclusions:

• Stress echocardiography is a versatile technique for cardiac assessment.
• Effective use depends on patient suitability, stress modality selection, and interpretation expertise.
• Limitations include acoustic window quality and inter-observer variability.
