What is the relationship between LDL cholesterol levels and atherosclerosis?

I - LDL cholesterol is responsible for the formation of atherosclerotic plaques.
II - The higher the LDL cholesterol levels, the greater the risk of developing atherosclerosis and coronary artery disease.
III - HDL cholesterol has a protective effect against atherosclerosis and coronary artery disease.
a) Only I is correct.
b) Only II is correct.
c) Only III is correct.
d) I and II are correct.
e) II and III are correct.

Ed · Answer

A alternativa correta é a letra "d) I e II estão corretas".

A relação entre os níveis de colesterol LDL e a aterosclerose é que o colesterol LDL é responsável pela formação de placas ateroscleróticas nas artérias. Quanto mais alto o nível de colesterol LDL, maior o risco de desenvolver aterosclerose e doença arterial coronariana. Portanto, as afirmações I e II estão corretas. Já a afirmação III está incorreta, pois o HDL colesterol não tem um efeito protetor contra a aterosclerose e doença arterial coronariana, mas sim um efeito benéfico na remoção do colesterol LDL das artérias.
