Cold-water fish like sardines will do it. But if you have cardiovascular disease, it would be better to completely change your diet to one that will reverse the disease. If that's your problem, check out "The Cardiovascular Cure" by John P Cooke, PhD.. Another good book is, "The Spectrum", by Dr. Dean Ornish.

I believe it works with any fatty (oily) fish. Salmon is good. Not sure about tuna.
A word of caution: There is such a thing as getting your blood too thin. Eskimos that eat a lot of fish have less heart attacks but they are at greater risk for hemorrhagic ( bleeding) strokes. Suppose you're in a bad car accident? You could bleed to death from blunt-force trauma. Also you might notice that you'll bruise more easily. If you get cut, you will see that it takes longer for the bleeding to stop. What if you need an emergency operation? How will they stop the bleeding if your blood is too thin?
