Low "GOOD" Cholesterol
(HDL)
Increased HDL Cholesterol
- Six-weeks of interval training also had a positive effect on levels
of the “good” cholesterol: HDL
- Mean levels were raised significantly (p=0.01) across all patients,
offering an increased protective effect against coronary artery disease
Added benefits for those with low HDL Cholesterol
Those beginning the programme with low levels of HDL cholesterol
(less than 1mMol/L) are at increased coronary risk however they attain
even greater benefits from the exercise with statistically significant
(p<0.0001) increases in this good cholesterol, protective against coronary
artery disease.
Risk reduction in those with a prior heart attack and low HDL
- The Framingham Risk analysis is a measure of cardiac risk which takes
into account several factors including age, sex, cholesterol, blood
pressure, weight and smoking habits
- In patients who have suffered a heart attack and have low levels of
HDL cholesterol a significant reduction in 5 year Framingham risk occurs
with the program
Risk reduction in those with ischemia and low HDL
- The Framingham Risk analysis is a measure of cardiac risk which takes
into account several factors including age, sex, cholesterol, blood
pressure, weight and smoking habits
- In patients who have angina/ischemia and low levels of HDL cholesterol
a significant reduction in 5 year Framingham risk occurs with the program
The Harmful Type B LDL Particle
Bad cholesterol, LDL, actually comes in various sizes. It is only the
small and dense Type B particles that are able to pass through holes in
the capillaries used for nutrient and oxygen transfer and lay down plaque
in the coronary arteries. The smaller your particles the larger the risk.
- Our research has demonstrated a correlation between LDL particle size
and the triglyceride/HDL ratio.
- If a person has a ratio greater than 2, 100% of their LDL particles
are the harmful Type B, placing them at greater risk of heart disease
and stroke. About 1/3 of all Australians fall into this group.
- By decreasing the T/HDL ratio, the amount of small dense particles
can be reduced thereby reducing the patient’s risk.
Reducing the T/HDL Ratio
Using exercise and life-style change alone we have significantly
reduced this ratio by 16%, meaning that by the end of six weeks the average
value for T/HDL is less than 2.0
