Question

Which of the following is a primary risk factor for the development of aortic dissection?

• A. Hypertension
• B. Diabetes mellitus
• C. Hyperlipidemia
• D. Smoking

Hint:

Hypertension is the leading cause of aortic dissection because it causes increased stress on the aortic walls, leading to potential tears.

Answer 1

The Correct Option is A

Step 1: Understanding aortic dissection.
Aortic dissection is a serious condition in which a tear occurs in the aortic wall, often leading to catastrophic consequences. Hypertension is the leading risk factor.
Step 2: Analyzing the options.
(1) Hypertension: Hypertension (high blood pressure) is the most significant risk factor for aortic dissection, as it puts excessive strain on the aorta.
(2) Diabetes mellitus: While diabetes can contribute to vascular diseases, it is not a primary risk factor for aortic dissection.
(3) Hyperlipidemia: Hyperlipidemia is a risk factor for atherosclerosis but not specifically for aortic dissection.
(4) Smoking: Smoking is a general risk factor for cardiovascular diseases but is not a leading cause of aortic dissection.
Step 3: Conclusion.
The primary risk factor for the development of aortic dissection is (1) Hypertension.
