Please Pray for my niece Diane - in ER internal bleeding

My niece had been unwell for two weeks and getting progressively worse so she went to her heart doctor who sent her to ER immediately. Diane has had problems with her heart for a long time. I have asked for prayers for Diane before and I am asking for your prayers again. Please pray that the problem in fixable. Her doctor said, "It's a good thing you didn't wait until tomorrow - she is in that much danger.
