Title: Major Disease Risk
1Major Disease Risk
2Anatomy of the Heart
- Atria are the smaller chambers of the heart.
Blood enters the atria first. - Ventricles are the larger chambers of the heart.
Blood travels from the atria to the ventricles. - Arteries are blood vessels that transport blood
away from the heart. - Veins are blood vessels that transport blood back
to the heart. - Capillaries are the smallest blood vessels.
3Anatomy of the Heart
- Pulmonary refers to the lungs. Blood travels to
the lungs from the heart to get oxygen into the
blood stream. - Coronary refers to the heart. Helps
differentiate which direction blood is traveling. - Myocardium is the name given to the actual heart
muscle that does the work. - Pericardium is the outer covering of the heart.
4Do You Have to Worry about Heart Disease Already?
- There are controllable and uncontrollable risk
factors. - Controllable risk factors are those that you can
alter your risk level for. Tobacco use, dietary
choices, lifestyle choices, and stress levels are
4 of the major controllable risk factors that
college students have to worry about. - The patterns you develop in college will tend to
follow you throughout your life.
5HD Prevention Physical Inactivity
- Entirely within your control!
- HD risk is higher for folks that dont exercise
compared to those that do. - Fitness level is more important than weight.
- The biggest increase in health benefits is for
the folks that currently dont exercise. That is
to say that you dont have to achieve a high
level of fitness to earn a lower HD risk.
6HD Prevention Obesity
- Obesity is largely a combination of your activity
level and your dietary choices. - Weight loss at any age causes a lessening of your
HD risk.
7HD Prevention Tobacco Use
- Smoking is the 1 risk factor for HD!
- 250,000 deaths from CV disease / year directly
related to smoking. - Smokers who do have a heart attack are more
likely to die from it than non-smokers. - Cigar smoking results in a lower, but still
significant risk. - 2nd hand smoke results in a 25 increase in your
HD risk. - Good news Quitting smoking immediately reduces
your risk up to 50. After 18 years of
non-smoking, your risk is equal to that of a
non-smoker.
8HD Prevention Elevated Blood Pressure
- Blood pressure is a measure of the resistance
your vessels have to blood flowing through them. - High Blood Pressure is called hypertension.
- The higher your blood pressure the higher your
risk for HD. - Control BP through diet, exercise, and medication
if those dont work.
9HD Prevention Blood Lipids
- Blood Lipids are made up of three parts
- High Density Lipoproteins (HDL) often referred
to as good cholesterol. HDL has the most
protein and has a preventative effect on HD
because HDL picks up excess cholesterol molecules
in the blood and transports them to the liver for
removal. - Low Density Lipoproteins (LDL) also carries
cholesterol in the blood but deposits it on the
walls of arteries. Also VLDL which is Very-Low
DL. - Triglycerides fats that flow through the blood,
especially after meals. These pose a larger
problem for women.
10HD Prevention Psychosocial Factors
- This is referring to stress levels. It is not
how much stress you have in your life, rather how
well you respond to those stressful situations
that we all encounter. - Three main types of stress
- Chronic nearly constant long-lasting stress
(job). - Episodic nearly constant for short bursts (new
job, moving, having a child). - Acute smaller scale, small time period (burnt
dinner, broken shoe lace, spilled coffee).
11HD Prevention Uncontrollable Factors
- Heredity
- Race / Ethnicity
- Age
- Gender
12HD Prevention Heredity
- Parents, siblings, other close relatives that
suffered heart attacks before 50 years old
increase your risk of HD. - Blood Lipids are one of the major hereditary
factors associated with HD.
13HD Prevention Race/Ethnicity
- Minorities in America experience HD more.
- 4 in 10 African Americans (AA) have HD.
- AA twice as likely as whites to develop HD.
- AA suffer strokes of greater severity and at
earlier ages. - Poverty may be the ultimate issue and not race,
but that link is not fully supported by science.
14HD Prevention Age
- 4 of 5 folks that die from a heart attack are
over 65 years old. - Decreased cardiovascular function is not
inevitable. You must focus on what you can
control and that can help alleviate the age risk
factor.
15HD Prevention Gender
- HD used to be a mens issue. Men have increased
incidence of HD before age 45 than compared to
women. - Male pattern baldness increases risk for those
under 55. - Menopause sharply increases the risk for HD.
16Healthy Numbers
- Hypertension
- 115 / 75.
- Cholesterol
- LDL
- HDL 40 is the minimum 60 has a preventative
effect. Some folks liken having HDL 60 to
being able to delete another risk factor. - Triglycerides
17Terminology of Heart Disease
- Arteriosclerosis is the general term for any
impairment of blood flow through the vessels.
Involves some hardening of the arteries. - Atherosclerosis a disease of the lining of the
arteries. - Plaque deposits of fat, fibrin, cholesterol,
other cell parts, and calcium that results in a
narrowing of the arteries. - Myocardial Infarction is the medical term for a
heart attack.
18Major Disease Risk
- Is it a heart attack?
- Tight ache, heavy, squeezing pain in center of
chest 30 minutes not lessened by rest. - Chest pain radiating to shoulder, arm, neck,
back, or jaw. - Anxiety.
- Sweating OR cold clammy skin.
- Nausea and vomiting.
- Shortness of breath.
- Dizziness, fainting, or loss of consciousness.
19Major Disease Risk Stroke
- Strokes occur when blood supply to a portion of
the brain is blocked. - 53 seconds that is the amount of time that
elapses in the U.S. between folks that have
strokes. - 20 of stroke victims die within 3 months.
- 50 are at least partially paralyzed on half the
body. - 20 cant walk again.
- HD, Cancer, Stroke that is the order of cause of
death in the U.S.
20Major Disease Risk Stroke Risks
- Uncontrollable Risk Factors
- Gender, race, age.
- Controllable Risk Factors
- Hypertension, high red blood cell count, heart
disease, blood fats, diabetes mellitus, estrogen
therapy.
21Major Disease Risk Cancer
- The uncontrolled growth and spread of abnormal
cells causes cancer. The nucleus of the original
cell loses control and the abnormal cell
replicates more of itself. - Benign group of abnormal cells but not
considered life-threatening. - Malignant is the kind of abnormal cells that are
classified as cancerous. These are bad. - Infiltration or Invasion is the process of
crowding out and replacing of healthy cells with
the abnormal cells. - Metastasize the spreading of cancer cells that
started in one location and move to other parts
of the body.
22Are You at Risk for Developing Cancer?
- 1 in 2 men develop cancer during their life.
- Women a 1 in 3 risk.
- Smokers have a 10 times greater risk to develop
cancer than do non-smokers!
23Cancer Risk Factors Uncontrollable
- Heredity
- Race / Ethnicity
- AA more cases of cancer 30 more likely to
die. - Obesity
- 14 men and 20 women deaths from caner linked
to obesity. - Infectious agents account for 17 of cancers
worldwide.
24Cancer Risk Factors Controllable
- Tobacco
- Cigarettes are the single largest cause!
- Nutrition
- The relationship of nutrition to cancer is
complex and ever changing. Certain foods are
linked to certain types of cancers. - Food preparation may play the largest role.
Avoid pesticides on your fruits and vegetables
cured, pickled, or smoked meats. - Charcoal grilling releases toxins similar to
those found in cigarette smoking.
25Cancer Risk Factors Controllable
- Obesity
- 1 in 6 cancer deaths.
- Excess weight may account for 14-20 of all
cancers. - Rate of weight gain also plays a role.
- Environmental Risks
- Environmental factors may cause between 80 90
of cancers. - Carcinogens cancer causing chemicals.
- Dark colored permanent hair dye has long been
linked to cancer, but current research is less
supportive of the link.
26Types of Cancer
- Carcinoma most-common skin cancer and the
lining of internal organs and glands. - Sarcoma supporting or connective tissues of the
body bones, muscles, blood vessels. - Leukemia blood forming tissues bone marrow,
lymph nodes, spleen. - Lymphoma cells of the lymph system.
27Helpful Hints
- Dont use tobacco!
- Stay in shape and remain physically active!
- Dont use tobacco!
- Stay in shape and remain physically active!
- Eat a healthy diet, taking into consideration how
food is prepared. - Please realize how many risk factors for major
diseases are related to tobacco obesity. You
can control both!
