Question

a patients parents have atherosclerosis. how is her family history most likely to affect her risk of developing abnormal blood pressure?

• it decreases her risk of developing high blood pressure.
• it decreases her risk of developing low blood pressure.
• it increases her risk of developing high blood pressure.
• it increases her risk of developing low blood pressure.

Explanation:

🆕 New Concept Discovered: Cardiovascular Disease Risk Factors
How genetics and arterial health affect blood pressure.

Step 1: Understand atherosclerosis

Atherosclerosis is a condition where fatty deposits, cholesterol, and other substances (collectively called plaque) build up inside the arteries. This buildup causes the arteries to narrow and harden, making them less flexible.

Step 2: Connect arterial hardening to blood pressure

When arteries lose their elasticity and become narrow, the heart has to pump much harder to push blood through them. This increased resistance to blood flow directly raises the pressure of the blood against the arterial walls, leading to high blood pressure (hypertension).

Step 3: Evaluate the impact of family history

Many cardiovascular conditions, including atherosclerosis, have a strong genetic component. Having parents with atherosclerosis increases a person's genetic predisposition to developing plaque buildup in their own arteries. Consequently, this family history increases her risk of developing high blood pressure.

Answer:

It increases her risk of developing high blood pressure.
