Myocardial ischaemia and viability: the pivotal role of echocardiography

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Echocardiography is crucial for diagnosing and managing coronary artery disease (CAD).
• It aids in emergency department chest pain evaluation, offering non-invasive hemodynamic and functional assessment.
• Stress echocardiography is increasingly favored for its cost-effectiveness and lack of ionizing radiation.

Purpose of the Study:

• To highlight the role of echocardiography in diagnosing and managing patients with suspected or known coronary artery disease.
• To emphasize stress echocardiography as a preferred imaging modality.
• To discuss advancements improving stress echocardiography's capabilities.

Main Methods:

• Utilizes echocardiography for non-invasive assessment of cardiac function.
• Employs stress protocols to evaluate patients with known or suspected CAD.
• Incorporates advanced imaging techniques like ultrasound contrast agents and deformation imaging.

Main Results:

• Stress echocardiography provides comprehensive hemodynamic and functional assessment.
• It is effective for risk stratification and assessing myocardial viability.
• New techniques enhance image quality and quantification, overcoming previous limitations.

Conclusions:

• Echocardiography, particularly stress echocardiography, is a vital tool for CAD assessment.
• Advancements in ultrasound contrast and deformation imaging have significantly improved its diagnostic utility.
• Stress echocardiography offers a safe, cost-effective, and radiation-free alternative for cardiac evaluation.
