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 evaluated left ventricular diastolic function before and after statin therapy. Impaired left ventricular diastolic function plays an important role in increasing the risk of congestive heart failure. Three diastolic function markers (E/A ratio, deceleration time, and isovolumetric relaxation time) were measured in 14 patients aged 51 to 79 years who completed three to six months of statin therapy. Worsening diastolic function was defined as a 10% decrease in the E/A ratio, a 10% increase in deceleration time, or a 10% increase in the isovolumetric relaxation time.
The study found that 71% of the patients had worsening of at least one marker of left ventricular diastolic function.

Silver concludes: "For more than a decade, there has been a suggestion of impairment of diastolic function after the administration of statins and our findings suggest that this may be a common event and potentially a precursor to symptoms associated with ventricular dysfunction".
