As far as the tests they do on animals to achieve heart disease, I would research more, from what I do know, often the amounts of anything used to test on animals are horribly much larger than what would be considered a normal amount to inhale, ingest etc. to produce the so called effect. Animal testing is disgusting but that is another story...
