For patients with hypertension who have normal filling pressures following right cardiac catheterization, can hypertension still be attributed to volume overload?

I do not think of chronic hypertension as a disease of volume overload. Loop diuretics are indeed very poor antihypertensive agents. I agree that cardiac loading conditions are dynamic, but in a patient with normal filling pressures and hypertension, I would think of inappropriately increased periph...

Yes. Diastolic pressures are dynamic and fluctuate quickly with the dynamic changes in daily blood pressure and salt load especially in patients with diastolic dysfunction myocardial mechanics.
