Outcomes issues regarding utilization of echocardiography in patients with known or suspected coronary artery disease
1Cardiovascular Division, University of Virginia School of Medicine, Charlottesville 22908, USA.
Insights
This paper discusses key factors for using echocardiography in coronary artery disease patients. It covers test performance, patient factors, and cost-effectiveness to guide appropriate utilization.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Echocardiography is frequently used in patients with known or suspected coronary artery disease.
- Determining the optimal utilization of echocardiography requires careful consideration of multiple factors.
Purpose of the Study:
- To discuss critical outcomes issues that should guide the use of echocardiography in patients with coronary artery disease.
- To explore concepts related to echocardiography utilization rather than providing an exhaustive literature review.
Main Methods:
- This is an opinion paper discussing concepts and issues.
- Key factors examined include training, test performance (sensitivity, specificity, artifacts), pretest probability, incremental value, cost-benefit analysis, and risk stratification justification.
Main Results:
- The paper outlines several critical factors influencing echocardiography utility in coronary artery disease.
- These factors include the need for adequate training and interpretation skills, understanding test performance characteristics, and considering the pretest probability of disease.
Conclusions:
- Appropriate utilization of echocardiography in coronary artery disease depends on a comprehensive evaluation of clinical context, test performance, and resource implications.
- Further investigation is needed in specific areas to refine guidelines for echocardiography use.
Abstract:
In this opinion paper, outcomes issues that should determine the utilization of echocardiography in patients with known or suspected coronary artery disease is discussed. The issues discussed are the level of training and competence in performing and interpreting echocardiographic studies, sensitivity and specificity of the test in various conditions, ability to deal with artifacts, the pretest probability of disease, incremental value of a test in context of what is already known about a patient, cost-benefit analysis, and whether risk stratification is justified when risk management is not possible. Concepts, rather than an exhaustive view of the literature, are discussed and areas that require further investigation are mentioned.
