FAMILY HISTORY OF HIGH CHOLESTEROL OFTEN NOT DETECTED UNTIL MIDDLE AGE

July 11, 2000

Families with a history of high cholesterol are being denied early treatment to
reduce the risk of coronary events because they often remain undetected until
middle age, according to a study in this week?s BMJ.


Using specialist registers and general practice records, researchers in
Oxfordshire compared the number of families identified as having a history of
high cholesterol with the estimated frequency of the condition. They found that
only about a quarter of the cases predicted were diagnosed routinely, and most
remained undiagnosed until middle age. Lack of diagnosis was greatest among
children and young adults: only two children under 10 years and 12 aged 10-19
years had been identified.





These findings have important implications for clinical practice as, in families
with a history of high cholesterol, the risk of a coronary event by the age of
60 without effective treatment is at least 50% in men and about 30% in women.
Underdiagnosis means patients are denied early treatment to reduce their risk of
coronary events, say the authors. They suggest a number of strategies to tackle
this problem, such as routine testing of patients with early onset coronary
artery disease and family tracking and testing by specialist nurses. Systematic
screening of all 16 year olds may be equally cost effective, they add.

The Great Cholesterol Con: The Truth About What Really Causes Heart Disease and How to Avoid It

The Great Cholesterol Con: The Truth About What Really Causes Heart Disease and How to Avoid It
by Dr. Malcolm Kendrick (Author)

Statins are the so-called "wonder drugs" widely prescribed to lower blood cholesterol levels that claim to offer unparalleled protection against heart disease. Many experts claim that they are completely safe and that they are also capable of preventing a whole series of other conditions. This groundbreaking study exposes the truth behind the hype surrounding statins and reveals a number of crucial facts, including that high cholesterol levels do not cause heart disease; that high-fat diets—saturated or otherwise—do not affect blood cholesterol levels; and that for most men and all women the benefits offered by statins are negligible at best. Other data is also provided that shows that statins have many more side affects than is often acknowledged. This...
