Aortic pain

Area of Science:

• Cardiovascular Medicine
• Thoracic Aortic Syndromes
• Pain Perception

Background:

• Historically, the thoracic aorta was not recognized as a primary pain-producing organ, except in cases of acute aortic dissection.
• Nineteenth-century clinicians and early twentieth-century experimental studies suggested the aorta could be a source of cardiovascular pain.
• Recent advancements in understanding aortic elastic properties and molecular biology have renewed interest in the aorta's broader functions.

Purpose of the Study:

• To review and consider the origins and recognition of thoracic aortic pain.
• To integrate historical perspectives with contemporary cardiovascular medicine concepts regarding aortic pain.
• To highlight the expanding spectrum of aortic conditions associated with pain.

Main Methods:

• Review of historical clinical observations and experimental studies on aortic pain.
• Analysis of contemporary research on thoracic aortic syndromes and aortic vascular biology.
• Integration of findings within the framework of modern cardiovascular medicine.

Main Results:

• The recognition of thoracic aortic pain has evolved significantly from historical views.
• Pain is now associated with a wider range of progressive aortic syndromes, including intramural hematoma, intimal tears, penetrating ulcers, and root dilatation.
• Experimental evidence, such as pain during aortic coarctation angioplasty, supports the aorta's capacity to produce pain.

Conclusions:

• Thoracic aortic pain is a recognized clinical entity associated with diverse aortic pathologies.
• Contemporary understanding integrates historical insights with molecular and physiological data on aortic function.
• Further consideration of aortic pain is crucial for comprehensive cardiovascular disease management.
