question: My 88 year old grandmother is in active congestive heart failure . Her B-type peptide blood test results went from 300 last week to 800 this week. Extreme difficulty breathing and fatigure. Her liver tests remain stable as do her kidney tests. She has been moved from hospital to skilled nursing facility. On average, understanding each patient is different, what is the life expectation for a patient at this stage? At an 800 level peptide, is it days? weeks? months?
