Consider a blood thinner like Eliquis as well. If the situation isn't critical, like others have mentioned a baby aspirin, nightly glass of red wine(all alcohol thins blood but red wine seems the best for heart), cayenne or other methods work as well. A major risk of thick blood viscosity from test is thrombotic events, which has killed guys like Meadows and others who had blood clots. You don't want clots, as then doctors will be afraid to do surgeries for fear a clot will break loose and kill you like supposedly killed David Dearth when he had a routine surgery. Although not heart related, Wheeler lost his leg due to a clot. Clotting issues are a major thing to avoid. Thin that blood.
