Abstract:
Thoracic aortic aneurysms (TAA) often represent the final manifestation of hereditary or degenerative disease processes. TAA are primarily caused by age-related degenerative changes. In this article, the authors highlight the most common pathophysiologic mechanisms responsible for TAA formation and review the paucity of evidence supporting the spectrum of medical therapies for TAA other than renin-angiotensin inhibition. More clinical trials on TAA are required before medical therapies such as beta-blockers, statins, and macrolide antibiotics can be recommended.

Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...
