chance of survival with brain surgery for aneurysm and heart failure?

hello.

a friend was admitted to icu a week ago for a rupture of blood vessel in her brain. she is 61.

while in there, drs found that she had an undetected heart attack a bit ago and one more just as the blood vessel ruptured. this caused half of her heart to become weakened. s

he has two aneurysms. one of which was coiled. theres still a lot of blood in her brain and liquid in her lungs.

she also developed a fever of 105.

today, drs said she had heart failure. her fever is slightly decreasing but her blood pressure fluctuates below what is expected.

what is her chance of survival given these conditions? shes been in for a week and seemed to get a bit better but everything seemed to go wrong today. I know nothing said is 100% because the patient isn't here to examine, but what can I expect?

thank you
