Just had a STEMI (ST elevation myocardial infarction) (HCC). Any advice?

It can be managed with meds and lifestyle changes. The best way to learn and to self manage is to ask the doctor for you to receive cardiac rehab classes. Insurance covers it up to a certain time after the event. You should attend all classes and not skip. The outcomes of the classes help in quality of the rest of your life us well documented

What everyone else said, plus take extra precautions not to get Covid. People with cardiac issues are at high risk for sad outcomes.

Yes, a forum basically for Caregivers caring for LOs is not who you should be asking these questions. Sounds like you are reading from a report. You need to sit down with your doctor and ask to tell you what it all means in layman terms. Tell him you want to hear the bad with the good. You may need to make some big lifestyle changes.

I think you are very lucky to have survived. People your age don't always. My daughter's friend just lost her 43 yr old sister to a heart attack.

I think unless you are running into a cardiologist on site here, you are likely to get little input from these details of your heart attack. Your EF (for others, this is the "ejection fraction" of the heart having to do with cardiac output) IS low. You are very young. You mention self neglect. Does that mean "overweight" by any chance? As a cardiac RN what I found from my own minimal home-grown research on my patients was that cholesterol numbers DIDN'T much matter, but that family history DID. That is to say, when I asked my young patients with an MI if they had a family history, (a father with early MI, say) they almost invariably said "yes" to that.
You have the diagnosis. Your cardiologist will follow you, and he or she is the best one to tell you what you can do to help yourself regain health now. I hope you are with Kaiser or another that has a good program for cardiac rehab. Some people turn their lives around, and I have seen people with quadruple bypass surgery do so, and live healthy and live long.
I want to wish you the best of luck in that. You may find you take great joy in a new healthy lifestyle. It is a goal and a mission, and we are at our best when we have mission and goal. Again, the very, very best of luck.

A STEMI is basically a type of heart attack. ANY heart attck is serious. Hence that old term "serious as a heart attack'.

You need to talk to a Dr and get the facts in language you understand. Not all heart attacks are the same. Your prognosis and care will be different from someone who had a 'different' heart attack.

If you never go to drs then how did you figure out your own health issues?

My 'guess' is that this is pretty bad and you'll need medical care. If you choose to not do so, well, the outlook is probably fairly dim.

If your doctor's name is "google' you really need to change drs.

Good Luck.

In layman’s terms, you had a heart attack, part of your heart muscle died, and your heart is pumping out 15 percent of the blood in your lower heart chamber as opposed to the normal 50-60 percent.

We are mostly all just people like you and couldn't possibly answer your question. Make the doctor stop and explain what this means, and ask them what specific terms and info you can look up on line.
