Heart Procedure

My father Carlos Ricardo Diaz suffered a heart attack a couple months ago in March.  We’ve  had nothing but bad news ever since.  My dad has medical insurance, but unfortunately they only pay out $2000 a year.  My dad had an Angiogram done which was over 11,000.  He then had another test done to determine if areas of his heart are even salvageable which was over $7000 .  If open heart surgery is even possible I’m sure this will cost well into the hundred of thousands.  
    Anything that anyone can help with will be greatly appreciated.  My family is not one for asking for help, but his medical bills are stacking up hard and fast.  We of course would not expect to raise enough money to pay for all or even most of his medical bills, but it will at least help him and give him some breathing room while he recovers and can slowly catch up and make payments on his own.  
      Being new to making a page as this I wasn’t sure the amount to put down.  This amount is a number I’m hoping for but of course any amount raised will be a blessing. 
     Thank you in advance for any help you were able to contribute! With much love from our family to yours.  Prayers are always greatly appreciated as well.
