@bluebonnet242 thanks for asking. I'm under the care of my current cardiologist for almost 3 years now. He did the following:

Lipid panel: LDL-c and triglyceride are the ones he looks at most, twice a year;
LP-a (just once is needed), APO-B, and hs-CRP;
Echo cardiocardiogram: Once a year for first two years, now once every 2 years;
CT heart with quantitative eval of coronary calcium: best to do before statin therapy; he said once every 5 years from now on;
PV vascular screening heart scan plus: screening for carotid artery disease, aaa (abdominal aortic aneurysms), and pad (peripheral artery disease);

We discussed the last three tests and I insisted to get them done for a baseline, and am very glad having those info on hand when I was evaluated for the suitability of estrogen therapy.

I had a second opinion from a women's heart specialist who adjusted my LDL-c target to < 55, and HbA1c target to =/< 5.6. She spent an hour evaluating all my labs and tests, my family history, past life style, current diet and exercise regimen. With her opinion, I felt very much at ease.

Hope this is helpful. Honestly, I'm not sure if all the tests and labs that i had are must-do's for hrt evaluation. Each person varies quite a lot in cardiovascular health regardless of age, seeking an individualized evaluation from a cardiologist before the start of estrogen therapy is definitely a good idea.
