Insights
Recent noninvasive diagnostic tests for coronary artery disease (CAD) show high accuracy. These methods can reduce the need for invasive coronary angiography (ICA), especially for patients with intermediate pretest probability of CAD.
Area of Science:
- Cardiology
- Diagnostic Imaging
- Medical Technology
Background:
- Coronary artery disease (CAD) is a major global cause of mortality.
- Invasive coronary angiography (ICA) is the gold standard for CAD detection but has limitations.
- Noninvasive diagnostic modalities offer a promising alternative for CAD evaluation.
Purpose of the Study:
- To review recent noninvasive diagnostic tests for CAD.
- To compare the diagnostic accuracy of invasive and noninvasive tests.
- To analyze the clinical implications of noninvasive CAD evaluation.
Main Methods:
- A narrative review was conducted.
- Relevant data were sourced from databases including Google Scholar, PubMed, and Embase.
- Online sources were systematically searched for pertinent information.
Main Results:
- Noninvasive diagnostic modalities demonstrate high accuracy in detecting CAD.
- The selection of noninvasive tests depends on patient characteristics, local resources, and pretest probability.
- Noninvasive testing is particularly suitable for patients with intermediate pretest probability of CAD.
Conclusions:
- Noninvasive diagnostic modalities can potentially reduce the reliance on invasive procedures for CAD.
- These tests provide valuable and reliable information for managing CAD.
- Further optimization of noninvasive tests is needed to fully realize their potential in CAD diagnosis and management.
Background And Aims:
Coronary artery disease (CAD), a leading cause of death globally, is among the most commonly diagnosed manifestations of heart disease. Although invasive coronary angiography (ICA) remains the "gold standard" to detect CAD, it is accompanied by several limitations. This review aims to present recent Noninvasive diagnostic modalities in CAD, report and compare the diagnostic accuracy of different invasive and noninvasive tests in CAD, and analyze both the current and future clinical implications of noninvasive modalities that regularly evaluate CAD in modern cardiology.
Methods:
Given this background and purpose, various, reliable online sources were searched to find relevant data for our narrative review. To this end, several databases were consulted including Google Scholar, PubMed, and Embase.
Results:
The weight of the evidence highlights that the accuracy of several noninvasive diagnostic modalities in CAD is high and the choice of the most suitable noninvasive diagnostic testing mainly depends on local resources, tests' features, and patients' characteristics, which determine the pretest probability of CAD. For patients presenting an intermediate pretest probability of the disease noninvasive testing seems to be appropriate.
Conclusion:
Noninvasive diagnostic modalities could limit the usage of invasive modalities in CAD. Nowadays, noninvasive diagnostic modalities are increasingly being promoted as they provide useful and reliable information about the various aspects of CAD. Undoubtedly, more efforts are needed to optimize noninvasive diagnostic tests to demonstrate their full potential in CAD.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
