47 years old and 2 stents

A little bit concerned and would be grateful for any information or advice
on what to expect. Had heart attack in July. I’m 47 and did not expect
this to happen to me. No one to talk to about it. I had one stint put in
and a 50% blockage in another artery. Two months later that artery blocked
completely even with all the meds and diet it still blocked. The good news
is I have lost 30 pounds the bad news is my HDL is super low and my doctor
says that is a bad thing. THANK YOU,
