Key result
Stress echocardiography yields superior specificity and comparable sensitivity versus other high-sensitivity tests for female CAD.
Why the study?
Strong comparative data on stress echocardiography for detecting coronary artery disease in women are lacking despite known sex differences in diagnostic test responses.
Does stress echocardiography accurately detect coronary artery disease in women with chest pain?
Does stress echocardiography accurately detect coronary artery disease in women with chest pain?
Stress echocardiography, particularly pharmacological stress echocardiography, is recommended as a first-line diagnostic tool for detecting coronary artery disease in women with chest pain due to its high specificity.
May inform noninvasive testing choices in women; leaves open need for prospective randomized validation.
1) Coronary artery disease in women differs from men in several ways, including their response to many diagnostic tests.2) Strong comparative data on stress echocardiography for detecting coronary artery disease in women are lacking, but existing data consistently show sensitivity comparable with other high-sensitivity tests and superior specificity, increasing its diagnostic accuracy.3) Pharmacological stress echocardiography appears to provide superior specificity to exercise stress echocardiography due to difficulties in test execution with the latter that increase the number of false positive results.4) Current evidence suggests that stress echocardiography should be the first-line diagnostic tool for detecting coronary artery disease in women with chest pain, but other noninvasive imaging tests may be valuable in some patient subgroups.

John R McKeogh (2007) conducted a review in Coronary artery disease. Stress echocardiography vs. Other high-sensitivity tests was evaluated on Diagnostic accuracy (sensitivity and specificity) for detecting coronary artery disease. Stress echocardiography provides comparable sensitivity and superior specificity compared to other high-sensitivity tests for detecting coronary artery disease in women.
