If you have a clotting disorder
you need to take medicine from your cardiologist! Are you overweight? Losing fat and doing cardio VERY regularly would also be very important. Eating a lower fat diet with lean mean, lots of veggies and fruit also VERY important of course, along with a glass of red wine now and then.
I know people who are big believers in Chelation Therapy
. It's a big thing these days, and people swear by it for clearing up arteries, but I don't know that much about it myself. Best luck.
