Google "the great cholesterol con", it's a fascinating read and very enlightening.
I haven't read the book, I'm not a doctor, and I know that I don't have the expertise to properly evaluate the scientific information myself and that I need to rely on others, but my understanding is that this hypothesis (it's all about stress and cholesterol has no impact) goes against conventional medical wisdom (which makes it less credible to me, but that may make it more or less credible to others depending on your perspective about conventional medicine).
Moreover, the book is from 16 years ago so it's pretty stale and there are at least 100's of studies since then supporting the cardiovascular and overall benefits of statins, including many long-term studies not done by drug companies, as these drugs are now largely generic.
P.s. You might read the top 1-star review on amazon for the scientific critique, though I am not qualified to evaluate that myself.
P.P.s. This is not to say there are no side effects or risks associated with statins.
