Blood Pressure is the force the blood exerts on the inside lining of the
blood vessels as it is pushed along by the heart.
Systolic Pressure is the force measured when the heart contracts. It is
the top number in a BP reading: 120/60
Diastolic Pressure is the force measured when the heart is relaxed. It is
the bottom number in a BP reading: 120/60
BLOOD PRESSURE
Normal Blood Pressure range = 110 – 120/ 60 -80
Pre High Blood Pressure range = 130 / 90
High Blood Pressure range = 140 + / 90 +
Hypertension is the name given to chronic high blood
pressure
BLOOD PRESSURE
Hypertension or Chronic High Blood Pressure can lead
to Atherosclerosis or narrowing of the blood vessels.
This increases the risks of Heart Disease and Stroke.
Heart Disease – narrowing or blocking of coronary
arteries
Stroke – narrowing or blocking of vessels carrying blood
to the brain
BLOOD PRESSURE
•Atherosclerosis is the gradual
blockage of the coronary
arteries.
•The upper picture on the left
shows a normal coronary
artery.
•The lower artery is 80% filled
with plaque.
•Chemical solution
•Laser
•Scraping
•Bypass surgery
•Angioplasty
Chemical, Laser, Scraping
and Bypass treatments
Chemical – there are medicines that can help
dissolve clots or thin blood to relieve
blockage.
Laser – surgery using lasers that break up the
blockage.
Scraping – micro surgery that physically
removes plaque on the sides of vessels.
Bypass – surgery that replaces blocked
arteries with harvested surgical grafts.
Angioplasty
This type of procedure involves a balloon on a
wire that is inserted through the femoral
artery in the leg. The wire is fed through the
artery until in position in the blocked artery
around the heart. The balloon is inflated and
deflated until the plaque is flattened and the
opening of the artery increased.
Stents
Stents are wire supports that can be inserted
after an angioplasty to support the vessel wall
and prevent it from collapsing or narrowing.
While High Blood Pressure can be a genetic problem
there are things one can do to lessen the risk.
Risk of Hypertension can be lessened through:
Diet
Exercise
Avoiding Smoking / Alcohol use
Managing Stress well
BLOOD PRESSURE
1. Research and list a suggested healthy diet that indicates
the number of calories per day, recommended foods and
foods to avoid or limit in order to reduce or maintain a
healthy blood pressure.
