Is Asymptomatic Carotid Artery Stenosis a Hidden Threat?
Published: Apr 22, 2024
Asymptomatic carotid artery stenosis is a condition that often goes unnoticed, yet it may lead to severe health issues like strokes. This article explores what this condition entails and why it matters.
Understanding the Condition
Asymptomatic carotid artery stenosis refers to the narrowing of the carotid arteries without causing symptoms. This condition is often undetected because it doesn't show immediate signs like a stroke or transient ischemic attack. However, identifying it early is crucial as it can indicate a higher risk for future cardiovascular problems.
Who Is at Risk?
The prevalence of this condition increases with age, making older adults more susceptible. Men tend to have a higher incidence compared to women. Risk factors include a history of atherosclerosis or other cardiovascular diseases.
Potential Consequences
The most significant risk associated with carotid artery stenosis is ischemic stroke. Although the annual risk of stroke due to this condition is low, the potential for cardiovascular events makes it a dangerous health concern. It serves as a marker for other serious conditions like heart attacks.
