Predictive value of the ear-crease sign in coronary artery disease
Insights
The ear-crease sign can help predict coronary artery disease in symptomatic patients. However, its value is limited in asymptomatic individuals, though it may indicate early aging and disease risk.
Area of Science:
- Cardiology
- Dermatology
- Preventive Medicine
Background:
- The ear-crease sign, a physical finding, has been anecdotally linked to cardiovascular health.
- Its diagnostic utility in predicting coronary artery disease (CAD) requires rigorous evaluation.
Purpose of the Study:
- To assess the sensitivity, specificity, and predictive value of the ear-crease sign for detecting coronary artery disease.
- To investigate the association of the ear-crease sign with CAD extent, risk factors, and patient demographics.
Main Methods:
- A study involving 340 consecutive patients undergoing coronary arteriography.
- Analysis of the ear-crease sign's correlation with diagnosed coronary artery disease and its characteristics.
Main Results:
- The ear-crease sign showed a sensitivity of 59.5% and specificity of 81.9% for CAD in this population.
- The sign was independently associated with obstructive CAD and more extensive disease in symptomatic patients.
- No significant correlation was found with most risk factors, except corneal arcus.
Conclusions:
- The ear-crease sign has moderate predictive value for coronary artery disease, particularly in symptomatic individuals.
- It may identify a subset of patients at risk for early aging and premature CAD, suggesting a role for early intervention.
Abstract:
The value of the ear-crease sign in predicting the presence of coronary artery disease was studied in 340 consecutive patients who underwent coronary arteriography. In this selected population, 75.6% of whom had coronary artery disease, the sensitivity of the sign was 59.5%, the specificity 81.9% and the positive predictive value 91.1%. The sign was associated with increasing age but was also independently associated with obstructive coronary artery disease. No significant correlation was found between the sign and the presence of risk factors or other signs of such disease, except for corneal arcus. In symptomatic patients the sign suggested the presence of more extensive coronary artery disease. In an asymptomatic population with a low prevalence of coronary artery disease it appears to be of limited value in predicting obstructive coronary artery disease. However, it may identify a subset of patients prone to early ageing and to the early development of coronary artery disease, whose prognosis might be improved by early preventive measures.

Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Imaging Studies for Cardiovascular System III: X-Ray
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...
