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 aimed to examine the impact of statins and low-density lipoprotein (LDL) cholesterol levels on survival rates in elderly patients with moderate and severe heart failure. The study included 212 patients, average age 77 years, who were followed for 3.7 years. The patients were divided into three groups according to LDL cholesterol levels:
(i) Group one had LDL cholesterol levels less than 90 mg/dL (2.32 mmol/l).
(ii) Group two had LDL cholesterol levels between 90-115 mg/dL (2.32-3.00 mmol/l).
(iii) Group three had LDL cholesterol levels above 115 mg/dL (3.00 mmol/l).

The study found:
(a) The total cholesterol levels of group one patients was 31% lower than group three patients.
(b) Group one patients were over twice as likely to be on statins than group three patients.
(c) Only 34% of group one patients survived longer than 50 months whereas 58% of group three patients survived longer than 50 months.

Charach concluded: "Low LDL cholesterol levels are associated with a reduced survival in elderly patients with clinically controlled moderate and severe heart failure. Statins were independently and significantly associated with a higher risk of mortality".
