Arrow Congestive Heart Failure and Chemical Stress Test

Hello Everyone,
I apologize in advance as this may be a bit winded. I am writing in regards to my 65 year old mother. In March of this year she was hospitalized with an exacerbation of COPD. She returned home in April only to return to the hospital for septic shock due to urosepsis. She has a history of left side diastolic heart failure, pulmonary hypertension, anemia, sleep apnea, copd, and a tracheostomy. She is on oxygen 24/7. She also has chronic atrial fib.

She is undergoing some pre-surgical testing before she has a procedure done to remove obstructed kidney stones that were the cause of her sepsis. They are planning on doing a dobutamine echocardiogram and a pulmonary function test next month. Her chest x-ray shows bilateral pleural effusions, which they increased her Lasix to help with this. I am concerned about this stress test because of her heart failure. I know that every procedure has its risks, but I worry because of her weakened state because of the septic shock she recovered from. Are the tests relatively safe? I know her EF is at 35%, but I am concerned about the effects of this procedure. Has anyone had a chemical stress test?

Thanks in advance!

Re: Congestive Heart Failure and Chemical Stress Test

I can't answer anything about CHF but I have had a chemical stress test.
They slowly inject you with a drug which increases the heart rate and if your mother is capable, they may ask her to ride a stationary bicycle at an easy pace for 4 minutes.
