The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

This study investigated the association between preoperative statins with the incidence of postoperative delirium in patients undergoing coronary artery bypass grafting. The study included 1,577 patients receiving preoperative statins who were matched with a control group of 1,577 not receiving statins.

The study found patients receiving preoperative statins had a 52% increased risk of postoperative delirium compared to patients not taking statins.
