Question

Hypertension increases ________ causing stroke volume to ________. hypertension increases ________ causing stroke volume to ________. preload; increase preload; decrease afterload; decrease afterload; increase contractility; increase

Answer 1

afterload; decrease

Step-by-step explanation:

• Hypertension increases afterload causing stroke volume to decrease.
• Hypertension refers to high or increased blood pressure. The afterload refers to the arterial pressure into which the stroke volume is ejected by the heart.
• Increased blood pressure or hypertension increases the left ventricular afterload as it must put more effort to eject blood into the aorta.
• This is due to the fact that the aortic valve can not open unless the pressure generated in the left ventricle is higher compared to the elevated blood pressure in the aorta.
