My Mother Is 81 Years Old. She Is Having Bowel

My mother is 81 years old. She is having bowel movements with red blood and blood clots. She has CHF and about 4 weeks ago got a stent in the left main. Her kidney and liver numbers are elevated in her blood. An ultrasound of the liver indicates that the heart issues has caused some cirrhosis of the liver. She is weak and aches all over. All her vital signs are good. Her kidney and liver numbers are still slightly elevated in the blood. The creatinine is 2.4.
The clots and blood only were passed this morning and have stopped now
What do you think this is?
