Doesn't that depend on heart attacks being a function of age rather than a function of time? Anti-aging doesn't necessarily mean anti-arterial-plaque-buildup. I do agree that entire classes of problems might go away though, which would be amazing.
Arteriosclerosis is a condition that is considered a part of aging/age related disease. Since it arise probably partly due to macrophages inability to break down extracellular aggregates (oxidised cholesterol) and lipids reacting with calcium that build up over time, as well as loss of elasticity of the arterial wall.

Imagine that EU funding is available for one ambitious, visionary project extending beyond 2020.
