Question

Which hemodynamic goals are most important in patients with aortic stenosis?

1) Adequate preload
2) Decreased afterload
3) Decreased contractility
4) Lower heart rate
5) Lower pulmonary hypertension
6) Maintaining mean arterial pressure

Answer 1

The most important hemodynamic goals in patients with aortic stenosis are adequate preload, decreased afterload, and maintaining mean arterial pressure.

Step-by-step explanation:

In patients with aortic stenosis, the most important hemodynamic goals are:

1. Adequate preload: This refers to the stretch on the ventricles prior to contraction. It is important to ensure that the ventricles have enough blood volume to pump effectively.
2. Decreased afterload: Afterload refers to the force the ventricles must generate to pump blood against the resistance in the vessels. In aortic stenosis, there is increased resistance, so efforts should be made to reduce afterload.
3. Maintaining mean arterial pressure: It is important to maintain an adequate mean arterial pressure to ensure proper blood flow and organ perfusion.
