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.

Assessment of apical radial pulse

Apical-Radial (A-R) Pulse Assessment
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

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
