>>> HEARD DISEASE IS THE LEADING
CAUSE OF DEATH IN THE UNITED
STATES BUT THERE ARE THINGS WE
CAN DO TO GET HEART HEALTHY AND
SO MANY DOLLAR WHAT IS THE DEAL
WITH GOOD CHOLESTEROL IS?
IS IT REALLY MINORITY OR COULD
HIGH LEVELS BE A PROBLEM FOR
OTHER HEALTH PROBLEMS ALSO HOW
CYCLING REDUCES YOUR HEART
DISEASE RISK.
AND USUALLY OXYGEN RISK BLOOD
KEEPS YOUR HEART MUSCLE HEALTHY.
HOW OXYGEN LEVELS AT MOUNT
EVEREST MAY REGENERATE THESE ARE
INTERESTING STUDY, ESPECIALLY
WHEN IT COMES TO CHOLESTEROL,
HDL IS THE CHOLESTEROL YOU WANT
MORE OF THE HIGH, YOU WANT MORE
OF IT.
AT LEAST THAT IS WHAT WE THOUGHT
BECAUSE IT WAS GOOD FOR OUR
HEALTH, BUT THIS STUDY LOOKS AT
IT A LITTLE DIFFERENTLY.
>> FOR THE LONGEST TIME WE'VE
HAD A SIMPLISTIC VIEW OF
CHOLESTEROL.
THERE WAS THE BAD CHOLESTEROL OR
LDL THAT RAISED YOUR RISK OF
HEART DISEASE AND HDL THAT
RAISED, WE SAID RAISE THE GOOD
CLOSE ROLL AND LOW WERE OUR BAD
CLOSE ROLL.
THIS STUDY TOOK A LARGE
POPLATION OF PATIENTS IN CANADA
AND LOOKED AT THEIR HDL LEVEL
AND WHAT THAT MEANT FOR THEIR
HEART RISK WHAT THEY FOUND WAS
THAT PEOPLE WHO HAD LOW HDLs,
THOSE MALES LESS THAN 40,
FEMALES LESS THAN 50, THEY HAD
HIGHER RATES OF NOT JUST
HEART-RELATED DEATHS BUT ALL
DEATHS EVEN CANCER.
LOW HDL WAS A MARKER FOR BEING
SICK OVERALL BUT THEN THE HIGH
LEVELS DIDN'T SHOW.
>> THERE CAN BE TOO MUCH OF A
GOOD THING.
I CAN'T TELL YOU HOW MANY TIMES
I'VE HAD A PATIENT COME IN AND
TELL ME AND SAY MY DOCTOR HAS
HIGH LEVEL OF BAD CHOLESTEROL,
BUT IT IS BALANCED OUT BY THE
GOOD CHOLESTEROL.
TURNS OUT THAT IS NOT REALLY
TRUE.
FOLKS WITH HIGH LEVELS OF GOOD
CHOLESTEROL, MEN OVER 70, WOMEN
OVER 90, THOSE FOLKS ALSO HAD
INCREASED RISK OF DEATH.
>> Melanie: WE WERE TALKING
ABOUT THINGS ASSOCIATED WITH IT
ABOUT, THOUGH.
SOMETIMES THE SMOKING, DRINKING
THAT IS THOSE LEVELS HIGHER
OR LOWER.
GETTING RID OF THOSE HABITS WILL
HELP TO LEVEL IT OUT WHICH THAT
HAPPY MEDIUM IS WHERE YOU WANT
TO BE.
LET'S TALK ABOUT CYCLING THIS IS
KIND OF SIMPLE.
WE KNOW EXERCISE HELPS TO
STRENGTHEN OUR HEART AND KEEPS
US LESS AT RISK FOR HEART
DISEASE.
WHAT IS ENCOURAGING PEOPLE TO DO
IS FIND CREATIVE WAYS TO GET
YOUR EXERCISE IN.
>>> EXACTLY, A COUPLE OF STUDIES
THAT CAME OUT ABOUT THE SAME
TIME AND IT WAS A LARGE
POPULATION OF DANISH FOLKS.
IN THEIR MIDDLE AGE ABOUT 40 TO
60 YEARS OLD IT IS NEVER TOO
LATE TO START EXERCISING.
FOLKS THAT SRTED EXERCISING
DURING THE STUDY PERIOD ACTUALLY
GOT SOME BENEFIT IN TERMS OF
HEART HEALTH AND IT WAS AS
LITTLE AS 30 MINUTES OF CYCLING,
A WEEK THAT GAINS BENEFIT.
>>> INSTEAD OF DRIVING TOKING
THE GROCERY STORE YOU HOP ON
YOUR BIKE AND GO AS A FAMILY,
EVERYONE PULL THEIR WEIGHT AND
THAT COULD HELP.
QUICKLY BECAUSE WE DON'T HAVE A
LOT OF TIME, BUT WE NEVER
THOUGHT WE COULD REGENERATE YOUR
HEART MUSCLE AND THIS NEW STUDY
LOOKED AT MICE WHICH THEN
THEY'LL HAVE TO SEE HOW IT WORKS
IN HUMANS BURKE THIS THOSE LOW
OXYGEN LEVELS THEY STARTED TO
SEE THESE CELLS REYEN RATE.
THAT IS PHENOMENAL.
>>> IT IS AN EXCITING NEW STUDY
OUT OF TEXAS.
THEY TOOK MICE AND DROPPED THEM
FROM AN OKAYNESS GENERAL
CONCENTRATION THAT WE NORMALLY
BREATHE AROUND 21%.
GRADUALLY OVER A COUPLE OF
WEEKS, TOOK THEM DOWN TO 7%
WHICH IS THE AMOUNT YOU MIGHT
SEE AT THE PEAK OF MOUNT
EVERREST.
AND WHAT WE FOUND WAS WHEN THE
OXYGEN CONCENTRATION OF THE AIR
THEY BREATHED WAS LOWER, THEIR
HEART CLELLS ACTUALLY TURNED
THAT SWITCH BACK ON THAT ALLOWED
THEM TO DIVIDE AND KIND OF HEAL.
AND THAT IS EXCITING NEWS AND
COULD BE GROUNDBREAKING FOR THE
AREA OF TREATMENT OF HEART
ATTACKS AND HEART FAILURE.
>>> WE'LL HAVE TO SEE WHAT
HAPPENS IF HUMANS.
THANK YOU SO MUCH FOR COMING IN.
IT WAS GREAT.
VERY SIMPLE AND WELL-EXPLAINED.
