My grandmother is 95 with CHF, atrial fibrillation and now pneumonia. She is in the hospital receiving care since she was having heavy palpitations, again. They discovered the pneumonia. She lives on her own, still drives without a license, is a stubborn woman, and has been able to manage on her own for the past three years since her 95 year old husband passed. Her doctor tells her she's amazing. Many of us believe she puts herself under a lot of stress by doing too much, entertaining others, constant housework... and this leads to exhaustion. Does the activity actually help her or hurt her? She just had a 2-day visit with family, a grandson, and a few dogs, which resulted in two days of obsessive house cleaning after they left, and now she's in the hospital five days later. Any suggestions? And what likely is her prognosis now that she's in hospital with CHF and pneumonia at 95 with heavy palpitations? Many thanks for your thoughts.
