Recently diagnosed with CAD - Scared to live

Finally, I have discovered others sharing my struggle.
I'm a 75 year old female with a history of life long high cholesterol, high blood pressure, a very, very long list of drug allergies and drug intolerance. Most of my adult life I ate very responsibly. My cholesterol would not go below 280, stayed around 380, and I continued to gain weight. At 50 years I reached my highest weight gain, 230 lbs.
Im 5'2" tall. I tried everything, and I do mean everything and could not lose weight. I stumbled across Whole Food Plant Based eating on utube. It sounded balanced, reasonable and I convinced my husband to join me. In one year I lost 100lbs, regained stamina and felt better than I had since childhood. My cholesterol levels dropped to 240. Then shockingly I had a major heart attack. The cardiologist found no blockages and very minor damage to the heart.
Months later, I had another cardiac episode with a total blockage to the aorta which was stented. Six years later No blockages some cardiac issues, Afib ablation, heart failure.
Bottom line, nonstop pressure to use Rapatha or other injections for cholesterol. I recently had a blood test which revealed my issues are definitely genetic high cholesterol.
I want to live my remaining years free from complications in my body caused by drugs.
How did those of you commenting find cardiologist who honored your wishes and ceased the strong arm tactics. I watched my father, sister and mother with both stroke and heart attacks. I know what could happen, however my family chose to eat whatever they wanted.
I live a disciplined strict life.
I may be fooling myself but I think my odds are better. They died much younger than me. (My Mom lived until 96 but had dementia for 20 years.)

I Live in a community with a MEDICAL School, most of the Dr.'s here have Med. Residents ...

Don't give up it's very manageable,
I'm a 73yr old male, and I live a very active life with heart disease , a little bit about my history , 9 stents and quadruple bypass surgery. I drank , smoked and had the worst diet in the world for 20 yrs

My doctor told me i had to change one thing everything, i haven't drank or smoked for 18 years, I do not eat any processed foods ,my diet is strictly a heart healthy diet healthy grains / I eat fish 3 times a week , chicken and hardly any red met / a lot of salads / extra virgin olive oil /red wine vinegar, no other dressing/lots of fiber and vegetables and fruit and good nuts every day

I'm in the gym 5 days a week for 1-2 hours at a time depending how i feel, I ride my motorcycle , play golf and runaround with my grandkids like i'm 50 yrs old. I average any where from 10,000 to 15,000 steps a day , lots of cardio 40 minutes a day (30 minutes brisk walking on a tread mill and a stationary bicycle for 15 minutes
and do strength training 3 days a week /dumbells and natural body weight (squats etc.)
Actually I'm in better shape now than when i was fifty with very minimal medication / one heart pill and one cholesterol pill
The quality of my life today compared to me when i was in my fifties is something I never thought was possible, my cardiologist told me there's no reason for me not to live well into my nineties if i stay on the track i'm on

If I can do it so can you , it's not the end of the world,
it could be a new beginning
God Bless

Young doctors need to learn too and just the fact that you’ve got access to them at all is a plus. Mid-level providers are worth their weight in gold and I believe they provide better care than some docs. Mid-level’s only handle a few patients while their bosses have greater responsibility and people under them hence more to manage. Just my opinion. But I’m glad you’re getting the care.
As for A-fib stats show for people under 60 5-9% develop A-fib and over 60 it increases to 10%. It’s considered a common illness of old age.
