I imagine there are very few parents who think about their small
children developing heart disease. Heart disease, after all, is
thought to be a condition that develops in the middle ages and in
the elderly. Unfortunately, coronary artery disease has been affecting
more and more relatively young individuals. I have seen countless
numbers of patients who have had heart attacks and coronary artery
disease developing in their thirties and even in their twenties.
Individuals who are particularly at risk of this are those known
to have the familial hypercholesterolemia with elevations in cholesterol
developing even in early childhood.
In a study published in the current issue of the prestigious journal
Circulation, researchers conducted an interesting trial. Fifteen
children with known familial hypercholesterolemia between the ages
of nine to twenty years old were evaluated. The average total cholesterol
in this group of fifteen children and young adults was 242 with
LDL levels of 187 (LDL cholesterol, otherwise known as bad cholesterol,
is considered abnormal when it is 130 or higher). Elevations in
oxidized cholesterol lead to changes in the inner lining of the
blood vessels with impairment of blood flow. In this clinical trial,
half of the children were treated with daily doses of 500 mg of
vitamin C along with 400 units of vitamin E daily for six weeks.
The other half of the children and young adults were given placebo.
All of the children were put on a diet that was rich in fruits
and vegetables and low in animal fats. At the beginning of the trial
and at the end of the trial, the researchers measured the dilation
(expansion) of the brachial artery, an artery found in the arm.
When the inner lining of the artery is damaged, the blood vessel
tends to stiffen and does not stretch to accommodate increased blood
flow. The researchers indicated that this is one of the early signs
of atherosclerosis. At the start of the study, the amount of dilation
of the brachial artery was 6% (with normal dilation of the brachial
artery in children being between 8 and 12%). Although the change
in diet did cause a modest lowering in the LDL cholesterol, it did
nothing to improve the dilation of the brachial artery. However,
those children treated with vitamin C and E had significant improvement
of brachial artery dilation up to a level of about 9.5% which is
clearly in the normal range. The children who were given placebo
pills had no change whatsoever. Dr. Engler, the lead author of this
paper, indicated that this was the first study to show that vitamins
can reverse arterial damage, commonly known as hardening of the
arteries.
This study is reminiscent of another fascinating study that appeared
JAMA in November 1997. In that study, 20 healthy individuals with
normal cholesterol were enrolled in a double-blinded placebo controlled
study. The participants in the study were initially given a high
fat meal. The meal was similar to what you would typically eat at
a fast food chain restaurant for breakfast including hash browns,
egg & sausage breakfast sandwiches, etc. After ingesting the meal,
those individuals had a significant decrease in brachial artery
vasodilation, dropping by approximately 50% for up to four hours
after consuming the meal. Individuals were then pretreated with
1000 mg of vitamin C, 800 units of vitamin E and then ingested the
same high fat meal. This time, however, the restriction in blood
flow did not occur.
It is not uncommon for someone to have a heart attack after consuming
a high fat meal. This is presumably secondary to the constriction
of blood vessels that occurs from this high fat food consumption.
However, it would seem that taking adequate doses of vitamins C
and E may prevent this from occurring. Supplemental vitamins C and
E are nutrients that everyone should be taking. Most one-a-day products,
however, contain negligible doses of these important nutrients.
The DV (daily value) for vitamin C is only 60 mg and 30 units for
vitamin E. Despite these small numbers, most individuals in this
country do not even consume the minimum DV.
It appears that inadequate levels of antioxidants may be a risk
factor for heart disease. Another major risk factor still not recognized
by most physicians is elevated homocysteine levels. Homocysteine,
an amino acid found in the blood was discovered in 1969 by a Harvard
researcher studying why certain children were dying young from heart
disease. For more info about homocysteine read this recent For Your
Health newsletter: "It's Time You Test Your Homocysteine."
For better cardiovascular function, it is recommended that everyone
get into the routine of taking vitamin C and vitamin E along with
adequate doses of B vitamins (which promote healthy homocysteine
levels), trace minerals and other antioxidants and phytonutrients.
The easiest way to get these important nutrients is from the Synergy
line of vitamin supplements from Nutraceutical Sciences Institute
(NSI). The most popular is Synergy Version 9 multi-vitamin. By taking
three capsules twice a day, you receive 500 mg of Ester-CÆ, 400
units of mixed natural vitamin E, B-complex at effective levels
along with a host of other antioxidants such as lutein, alpha lipoic
acid, grapeseed extract, CoQ10, ginkgo biloba and more. The Synergy
multi-vitamin has been continually improved over the past eight
years, and was just recently reformulated (Version 9). The cost
of this product is just under $1.00 a day.
