percent. For those who take cholesterol-lowering
medications, following the TLC program can ensure
that they take the lowest dose needed to achieve
results.
Precautions
Along with a qualified physician, making sure that
qualified professionals who can assist with safe dietary
and lifestyle changes should include registered dietitians,
doctors, nurses, psychologists, and exercise physiologists.
Risks
According to the NCEP Guidelines, all adults 20
years of age and older should have their total choles-
terol as well as HDL-cholesterol measured every five
years.
Risks
Positive Risk factors for heart disease:
Male greater than 45 years of age
Female greater than 55 years of age
Female with premature menopause without estrogen
replacement
Family history of premature coronary heart disease
having definite myocardial infarction or sudden
death before age 55 in father or other first-degree
male relative, or mother before age 65 years of age
Currently smoking or history of cigarette smoking
Blood pressure greater than 140/90 mmHg or on
antihypertensive medications
HDL cholesterol less than 35 mg/dl
LDL cholesterol greater than 130 mg/dl
Diabetes Mellitus
Research and general acceptance
Scores of research articles support a direct rela-
tionship between LDL cholesterol levels and the rate
of coronary heart disease (CHD) in a person. Within-
population studies such as the Framingham and
MRFIT studies and between-population studies,
most notably the Seven Countries study support this
research as well. Studies on familial Hypercholestero-
lemia, a genetic disorder characterized by high levels
of LDL cholesterol, have an exceedingly high rate of
premature atherosclerosis. The majority of research
from experimental animals, laboratory investigations,
epidemiology, and genetic forms of hypercholestero-
lemia indicate that elevated low-density lipoprotein
(LDL) cholesterol is a major cause of CHD. In addi-
tion, clinical trials demonstrate a reduction of coro-
nary heart disease risk when low-density lipoprotein-
lowering therapy is instituted. For these reasons, the
NCEP Expert Panel on Detection, Evaluation, and
Treatment of High Blood cholesterol in Adults
(Adult Treatment Panel III) continues to identify ele-
vated low-density lipoprotein cholesterol as the pri-
mary target of cholesterol-lowering therapy.
