A number of _____ are known to directly affect blood cholesterol levels and the risk of heart disease.

Question

Quizplus · Accepted Answer

Genetic disorders and variations in gene types are known to have a direct impact on blood cholesterol levels and the risk of heart disease. Examples include familial hypercholesterolemia, which is an inherited condition that leads to high levels of LDL (bad) cholesterol, and certain variations in genes such as APOE and PCSK9, which also affect cholesterol metabolism.

None of the other options listed have a direct impact on blood cholesterol levels and the risk of heart disease. Psychological factors, such as stress and depression, can indirectly affect heart disease risk through their impact on lifestyle behaviors like diet and exercise. Environmental factors, such as pollution and exposure to toxins, can also contribute to heart disease risk, but again, not through their direct impact on blood cholesterol levels. Childhood illnesses and autoimmune diseases may have indirect impacts on heart disease risk, but they are not directly related to blood cholesterol levels.
