My boyfriend (50) only has 15% of his heart working. He's been feeling nausea and is light headed, has weird dreams. Is he close to dying?

You need to get him to an ER. If u have Hospice you need to call the nurse. She should be available 24/7.

This is a question and concern to share with his doctors. None of us here can predict what’s occurring or when it might. I hope you have hospice services in place to help guide you both. Wishing you both peace
