A question about blood pressure relating to heart disease

A question about blood pressure relating to heart disease?
If you have congestive heart failure, would that cause your blood pressure to be low, because the heart isn't pumping enough? And if you have a blocked artery(without heart failure), would your blood pressure normally be higher than normal, due to the heart having to work harder?

1 :
Blood pressure in congestive heart failure actually typically increases because of the fluid that builds up in the cardiovascular system ahead of the heart because the heart isn't string enough to pump all of the blood forward. Blood pressure doesn't typically increase if you have a blocked artery unless it is a major artery.
2 :
CHF can increase BP (fluid accumulation), but generally pt's are on medication to keep it low. Lower BP decreases the workload on the heart so this is good for CHF patients. As far as the blocked artery it would really depend on the extent of the blockage and the artery that is involved.
3 :
BP is dependent upon the pumping pressure able to be generated by the heart, fluid/blood level in all the vessels, and pressure in the body's arterties that the heart has to pump the blood thru/against...complicated. That is why treating BP is so multi-faceted...When you refer to a blocked artery, that means a blocked coronary artery. The coronary arteries feed blood to the heart muscle itself, and a blockage there can effect the ability of the heart tissue/muscle to pump effectively. This is opposed to thinking that a blocked artery is out in the body and the heart is having to pump blood out to the body against this resistance
