Speckle tracking stress echocardiography: A valuable diagnostic technique or a burden for everyday practice?

Area of Science:

• Cardiology
• Medical Imaging
• Diagnostic Techniques

Background:

• Early diagnosis of coronary artery disease (CAD) is crucial for reducing cardiac mortality.
• Current guidelines recommend functional imaging over electrocardiogram for detecting myocardial ischemia and assessing myocardial viability (MV).
• Stress echocardiography is accessible but has limitations in diagnosing subtle CAD, small lesions, or microvascular angina.

Purpose of the Study:

• To review the potential benefits of combining speckle tracking imaging with stress echocardiography.
• To evaluate the suitability of this combined approach for early myocardial ischemia detection and MV assessment in various clinical scenarios.
• To assess its potential role in managing chronic coronary syndromes (CCS).

Main Methods:

• Review of existing evidence on the integration of speckle tracking imaging and stress echocardiography.
• Analysis of diagnostic accuracy and clinical utility in different patient populations and CAD presentations.
• Comparison with current standard diagnostic approaches for CAD.

Main Results:

• Speckle tracking imaging integrated with stress echocardiography demonstrates promising results in enhancing diagnostic accuracy.
• This combination may offer a more sensitive approach for detecting subtle myocardial ischemia and evaluating MV.
• Despite promising findings, its use is not yet included in current CCS guidelines.

Conclusions:

• Combining speckle tracking imaging with stress echocardiography holds significant potential for improving early CAD detection and MV assessment.
• Further research and clinical validation are needed to establish its role in routine practice and guideline recommendations.
• This integrated technique could offer a valuable, sensitive, and accessible tool for cardiologists.
