Damar sertliğini oluşturulan unsurlar
1) Aşırı kilo
The 1999 Health Survey for
England revealed that
19% of men and 21% of
women are clinically obese
44% of men and 33% of women are overweight.

2) Sigara
Smoking is the biggest risk
factor for sudden death; up to 18 in every 100
deaths from heart disease are associated with smoking.
Слайд 99
How does smoking cause heart disease?
Smoking damages coronary artery
walls eventually causing them to harden and narrow and reduce
blood supply to the heart muscle.
Smoking lowers HDL-cholesterol (good cholesterol).
Smoking increases fibrinogen in the blood which makes your blood more sticky and likely to clot.
Smoking increases your heart rate and blood pressure.
Smoking removes oxygen from the blood and replaces it with carbon monoxide
Слайд 1010
What makes smoking harmful?
Tobacco
smoke contains over 4000 chemical compounds but
nicotine and carbon monoxide are the two that are most
dangerous for your heart.
Nicotine
Nicotine stimulates the body to produce adrenaline which makes the heart beat faster and raises blood pressure, causing the heart to work faster.
Carbon monoxide
joins onto haemoglobin in the bloodstream making it less able to carry oxygen to the heart muscle and all other parts of the body. Up to half the blood can be carrying carbon monoxide instead of oxygen in some smokers.
Tar
is brown and treacly in appearance and causes cancer. Low tar cigarettes can be just as harmful to your heart health.

Слайд 2020
What causes stress?
exams Listening the news
arguments homework
being left out of a group a new school
girl friends / boy friends being late

5) Hareketsiz yaşam
Слайд 2222
Physical activity plays an important part in preventing heart disease
by helping to:
Reduce your risk of having a stroke.
Increase HDL-cholesterol level.
Reduce your weight
Control blood sugar (glucose).
Reduce your chance of developing diabetes.
Prevent blood clotting.

What Blood Pressure Is Considered Too High?
120/80 -
Normal
139/89 - Prehypertension
(This means that you do not have
hypertension, but you are likely to develop it in the future unless you adopt lifestyle changes to keep your blood pressure under control)
140/90 - Hypertension
Слайд 2626

Computed Tomography (CT) Scan
CT scan is an x-ray technique
that uses a computer to create slice-like pictures of the
heart.
The patient lies on a scanning table,
The CT scanner takes many x-ray pictures of thin slices of your heart.

top of the left ventricle.
It shows a normal

Doppler ultrasound or "echo"
Echocardiography
Слайд 4242
The echo actually consists of three different procedures:
Слайд 4343
1) M-mode echocardiography Technique
In the M-mode a single beam of
ultrasound is used
Слайд 4444
M-mode echocardiography
M-mode echocardiography provides a one-dimensional moving image of the
heart. The waves indicate structures in the heart, such as
the valves, chambers, and walls.

Exercise EKG, or Stress Test
The patient is attached
to the EKG machine.
The patient exercises by walking on
a treadmill or pedaling a stationary bicycle while the EKG is recorded.
This test is done to assess changes in the EKG during stress such as exercise.
