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.

An implantable cardioverter defibrillator (ICD) is a battery-powered device placed under the skin that keeps track of your heart rate. Thin wires connect the ICD to your heart. Abnormal heart rhythms (or arrhythmias) can cause your heart to beat too quickly, too slowly or in an irregular pattern. These heart rhythms can happen suddenly and unexpectedly and sometimes people die as a result. If an abnormal heart rhythm is detected the device will deliver an electric shock to restore a normal heartbeat.

This study investigated the influence of statin therapy on the well-being and health status of patients with an implantable cardioverter defibrillator. The study included 409 patients who completed a health survey before implantation and three, six, and 12 months after implantation of the implantable cardioverter defibrillator. Of the 409 patients, 60% were prescribed statins.

The study found:
(a) Statin use was associated with poorer physical functioning.
(b) Statin use was associated with poorer social functioning.
(c) Statin use was associated with worse depression.

In conclusion, statin therapy was associated with impaired health status in patients fitted with an implantable cardioverter defibrillator.
