Medical expenses for Bub Hughes

My best friend Bridgett has been through a lot in the last couple of years. Things once again went sideways last Saturday evening when her husband Bub (Denver) Hughes had a heart attack. His heart function is incredibly low at between 10-14%. Uninsured, his expenses are going to be incredible, and there are some very expensive equipment and medications he will need for several months to give his heart muscle the chance to (hopefully) start functioning again. Please help to whatever extent you can.
