Treating Low Blood Pressure in Elderly Congestive Heart Failure Patient
by westes, May 22, 2009
My 85 year old father has congestive heart failure and occasionally he gets very low blood pressure, around 85 over 55.    Needless to say when this happens he feels very weak and has problems moving around.

His cardiologist feels that this is part of his disease as it enters its end stage, and he feels there is nothing we can do to treat this safely.   What I don't understand is why other times his blood pressure is a more normal 105 / 70.  At that pressure he is fairly functional.

What causes the blood pressure to fluxtuate so much?   When the pressure is low, should we think about possibly giving him some extra liquids, just to get his blood volume higher?   Should we be trying to force him to exercise (with someone there to hold him obviously)?  Is there really nothing we can do during these low blood pressure episodes to try to bring up the pressure safely?

Blood pressure is a complex interaction between cardiac output and peripheral vascular tone. It varies from minute to minute and hour to hour, and it is probably related to neurovascular tone more so than cardiac output. The low numbers of blood pressure are usually not significant unless he feels the effects of this, which are usually not fatigue, etc, but more likely to be dizziness, lightheadedness or passing out. If these occur he may need a decrease in the medications doses or decrease in the frequency of the medication.
Unless he is on a diuretic,  or has poor oral intake in a hot setting then volume depletion is usually not a cause and volume repletion will probably not help.

Another question related to this condition.     My father's weight fluctuates from 113 lbs to 130 lbs.   At 130 lbs he has severe congestive heart failure symptoms and typically needs to be on an aggressive managed diuretic.   When he gets out of the hospital after such an episode - with all of the water removed - his weight is only 113 lbs.

Based on that range, what would be a reasonable target weight for such a person?   We could simply aim for a mid point, but I'm wondering if there are general guidelines to use for establishing a target.
