My Mom denied an HA one night in May a few years ago. She waited until her next scheduled PMD appt in August to tell her doc (and me). We were rushed to the hospital and put in ICU (her not me).
Because of the delay, part of her heart muscle was dead and there was no option for stents. They put her on meds and optimized things as best they could.
She is doing well but gets very short of breath when she walks much or does stairs.
I have no idea what is happening w you. I just worry.
