Anyone out there w very high CAC and high LP(a) ?

Went for executive physical for no reason other than husband said to go with him. Labs indicted 234 total cholesterol w highish LDL of 138. Doc wanted CT CAC score. Cried when it was 740. Then doc wanted Lipoprotien (a) test. Devastated at 170. Went on 10 mg atorvastatin. Changed lifestyle. After two months LDL is 78. triglycerides 38 My BP always 120/80 or less and passed stress test. It’s devastating to know that LPa is hereditary and causes plaque and clots. I’m 63 and need to lose 20 lbs. but feel very scared. Clinging to hope and faith that I can live long time. If anyone in my boat I’d like to hear from them too.
