Dear Zarak, Hypertension, in particular diastolic hypertension, is widely seen among patients with aortic aneurysm, and with it comes a greater risk for rupture. Clinicians who manage patients with TAAs must be cognizant of the risk factors for TAA rupture. The risk of abdominal aortic aneurysms (AAAs) increases dramatically in the presence of the following factors: age older than 60 years, smoking, hypertension and Caucasian ethnicity. The risk of abdominal aortic aneurysms (AAAs) increases dramatically in the presence of the following factors: age older than 60 years, smoking, hypertension and Caucasian ethnicity. An abdominal aortic aneurysm (AAA) is a focal dilation () 50 percent greater than the normal diameter of the aorta. ... of AAA and include large aneurysm diameter, rapid expansion, smoking, hypertension, elevated peak wall stress, a history of cardiac or renal transplant, decreased forced expiratory volume increase the chances.

Dear Dr Zarak

Chronic arterial hypertension has been widely accepted as the most common acquired condition that leads to dissection of the aorta from high shear stress. Nearly 75% of patients with AAD have a history of hypertension

Thank you for sharing your answer.

kindly suggest me that is it smoking or Hypertension that affects Abdominal Aortic Aneurysm the more.

Hi Muhammad,,, abdominal aortic aneurysm and hypertension are much more correlated. Thoracic aortic aneurysm are much more commonly associated with genetic, familial and atherosclerotic origin. However 70percent of thoracic aortic aneurysm are associated with hypertension. Hypertension is also a important contributing factor in pathogenesis of aortic dissection in this condition. So controlling hypertension in patients of thoracic aortic aneurysm may have great benifits in reducing the incidence of complications.. Following link might help you.. Thanks

Thank you 😊

Hi Muhammad,,, hypertension and smoking are both positively correlated with abdominal aortic aneurysm. Important risk factors for abdominal aortic aneurysm are male sex, smoking, low HDL, atherosclerosis etc. Hypertensive probably does not initiate the abdominal aneurysm. It is the weakening of vessels wall caused by the various risk factors that initiates the formation of aneurysm and hypertension exacerbate it's progression. However all factors may be interrelated and that's why treating hypertension may be beneficial in both thoracic and abdominal aortic aneurysm.. Thanks

Thank you sir

Undoubtedly systemic hypertension is a major risk factor for both Thoracic and abdominal aortic aneurysms. In the absence of hypertension or cystic median necrosis related to Marfan or other connective tissue disorders, Aortic aneurysms and dissection especially of the Thoracic aorta are uncommon. However, smoking is an equally important etiological factor for abdominal aortic aneurysms. In some studies, smoking is found to have stronger correlation with Abdominal aortic aneurysm than hypertension.
