What causes increased afterload in the left ventricle due to arterial stiffness during hypertension?

A)Enhanced venous return stimulation
B)Reduced end-diastolic volume increase
C)Increased atrial natriuretic peptide secretion
D)Elevated systemic vascular resistance

💡 Explanation

Arterial stiffness raises blood pressure and increases systemic vascular resistance because the arteries lose their elasticity. Therefore, the left ventricle must work harder to eject blood, leading to increased afterload, rather than changes in venous return or ANP secretion.
