Prayers for my dad

Coming here for ones that believe in prayer. My dad started having a fast heart rate about 3 months or so ago and his doctor hooked him to a 24 hour heart monitor and sent him to a heart doctor for a heart ultrasound. Today he got the results, he has a-fib and a weak heart. They put him on 3 different meds and told him to stay away from fatty foods, salty foods and he's going to have dye ran in his heart to check for blockages. They said his heart is so bad he could have a stroke. Needless to say my mom, myself and my brothers are worried sick. It's not his time to go anytime soon, he's only 54 years old. Ughhhh..just please please pray they caught it early and he will be okay.

UPDATE: His doctor called him back and said he's has Congestive heart failure and really bad blood flow. 😢
