bad-genes, Thank goodness you went in for a appointment BEFORE you had a major event happen.
Obviously you should follow all your doctor's advice regarding the meds and tests.
Having said that, if I were in your shoes I would also make a rapid and radical change in my diet.
You might Google (bill Clinton heart diet) and see what the ex-president has done to make his odds better.
Now, he did have a bypass, but even after that he didn't make all the dietary changes he could, until his bypass started re-blocking.
That was his final warning and with that he finally made huge changes in his diet. He gave up his prior mild change routine and went full-on with the new diet.
I won't tell you to follow doctor x or diet z, but begin reading about all the changes Bill Clinton finally made and the doctors he follows regarding dietary advice. You may want to do what he finally found necessary.
Do some extensive reading. He got the best advice he could and now credits his ongoing health in part to those changes.
The changes will be huge for a person eating a normal American diet, but they give you a additional way to improve your odds of living longer without a serious event and/or the need for bypass.
Your doctors won't insist you do this, but at the same time I can't imagine they won't tell you it would help.
Remember, even a radical dietary change is no substitute for following all your doctor's other advice.
We're talking about very serious matters and though changing one's diet in a dramatic way is difficult at first, I can only say that were I in your situation, with your family history, I'd begin the changes tomorrow.
I wish you well.
