Aortic dissection remains a difficult diagnosis to make. This article is a nice review.  The pathology behind this involves an intimal flap in the aortic wall. Death occurs due to aortic rupture or obstruction of branching artery. 

Risk factors: male 2:1 female, Marfan Syndrome, HTN, aortic aneurysm, cocaine and methamphetamine use, pregnancy

Pain is variable however tearing, ripping migrating, maximum at onset, and sharp are all associated with Aortic Dissection. Think about Dissection with atypical CP with ECG changes as well as in stroke like presentations along with chest pain. 

Gold standard for diagnosis is CT angiogram. Decision rules with the use of D-Dimer have been proposed however there is still not sufficient evidence to use these. ACEP guidelines currently give use of decision rules a long with DDImer a level C recommendation.
