A similar myth is that fatty foods lead to clogged arteries. I won't bother to go fetch links but let's just say my room mate was drunk and literally screaming this at me at 2AM once, over and over like a child, and the only way to talk him down was to promise I'd go research it at reputable websites and bring him "the proof". Yes you can refute this myth at such as CDC, Mayo Clinic, etc.
If anything, most arteries problems are caused by high sodium. Salts osmose water out out cells, causing "hardening", leading to arterial damage, attracting clotting factor, which builds up and is compounded with some forms of cholesterol in some people (but can still be bad enough on its own), which leads to clogged (clotted) arteries. Then you run into this terrible catch-22 with vitamin K where K is needed to repair the arterial damage but K also goes into producing clotting factor. So the doctors tell you to cut K completely out of your diet, eat liver-killing blood thinners, and shift the problem to yet another part of your body while also synthesizing a condition of hemophilia.
If anything, people worried about clots should cut any high intake of salt out (but not entirely out), not fat out of their diet. Blood pressure completely aside.
And something else fun to learn is that there is a gut flora that produces something called TMAO that can compound and/or cause any artery problems you might have. The great news? The gut flora produces TMAO from l-carnitine. So take your doctor seriously if they recommend cutting red meat intake entirely.
