My former cardiologist invented the calcium score and it enabled me to avoid statins despite having (congenital) high cholesterol when the test yielded a calcium score of 0 and, 7 years later, 4. I take calcium supplements in addition to vitamin D3 and vitamin K2. My current cardiologist notes that "the research suggests" that K2 has some protective ability to prevent arterial calcium build-up and Google Scholar searches on the topic yields research studies on the topic.

Calcium is important in preventing osteoporosis so it gets my attention. And while I'm on the subject, 67% of the cases of osteoporosis in the US are women. Simple arithmetic suggests that more than a third of the cases are in men. But I have yet to hear of one older male friend whose primary care physician suggested a DEXA scan which seems very short-sighted. I don't see any reason why men should have to grow stoop-shouldered and osteo-frail as they age so why aren't doctors addressing this?
