What Causes Heart Disease/Stroke?
• Arteries—blood vessels that carry blood away from the heart to the rest of the body

What Increases Risk?
You Can Not Help• Age
– Men: >45 years– Women: >55
years
• Sex• Race• Family history

How Can You Play the Cards?
Biometric Screening Tests
• BMI• Blood pressure• Lipid Panel
– Total cholesterol– High-density lipoprotein (HDL)– Low-density lipoprotein (LDL)– Triglycerides
• Blood glucose• A1c
Body Mass Index (BMI)
• BMI is a number calculated from a person’s weight and height
• Higher BMI values are associated with risks for health problems
• Visit http://www.cdc.gov/healthyweight/assessing/bmi/

Maintain a Healthy Weight
Body Mass Index (BMI)Underweight <18.5
Normal Weight 18.5-24.9
Overweight 25-29.9
Obesity 30+
Benefits of Weight Loss (cont’d)
• Weight loss:– Reduces risk for cardiovascular disease– Lowers blood pressure– Lowers blood sugar– Improved lipid levels

Blood Pressure
• What is blood pressure?– Pressure created by the heart as it pumps
blood through the arteries and the circulatory system
• What do blood pressure numbers mean?
– Top number (systolic)=pressure while heart is beating
– Bottom number (diastolic)=pressure while heart is resting, between beats
Blood Pressure (cont’d)
• How can I tell if I have high blood pressure”
• Typically no symptoms—”silent killer,” but could experience
– Headache– Blurred vision– Dizziness– Nausea
Blood Pressure (cont’d)
• Over time, high blood pressure can damage:
– Blood vessels– Vision– Heart and other organs– And increase your risk for heart attack, stroke,
and kidney failure• A reduction of as small as 2 mm Hg in
the average American’s systolic blood pressure could save more than 70,000 lives per yearmmHg=millimeters of mercury

Blood Pressure (cont’d)
Blood PressureSystolic/Diastolic
Classification
<120/<80 Normal
120-139/80-90 Prehypertension
140-159/90-99 Stage 1 hypertension
>160/>100 Stage 2 hypertension
>180>110 Severe hypertension
Lipid Panel: Why Get Tested?
• To determine risk of coronary heart disease, heart attack, and stroke
• One in seven adults are high risk• Worldwide=4.4 million deaths
Lipid Panel (cont’d)
Every 5 years starting at age 20:• Total cholesterol, if elevated
associated with heart disease• HDL (healthy cholesterol)• LDL (lousy cholesterol)• Triglycerides
Total Cholesterol
• Every 1% reduction in your cholesterol, reduces your risk of heart disease by 2%-3%
Total Cholesterol Category
Less than 200 mg/dL Desirable
200-239 mg/dL Borderline high
240 mg/dL and above High
dL=deciliter, mL=milliliter
LDL (Lousy) Cholesterol
• LDL=low-density lipoprotein
dL=deciliter, mL=milliliter
LDL Value Category
Less than 100 mg/dL Desirable
100-129 mg/dL Elevated
130-159 mg/dL Borderline high
160-189 mg/dL High
190 mg/dL+ Very high
Decrease Saturated and Trans Fats
Harmful fat
Food source
Saturated Fat
Animal products (meat, poultry, eggs, dairy products, lard, and butter), and coconut, palm, and other tropical oils
Trans Fat Partially hydrogenated vegetable oils, commercial baked goods (cookies, crackers, and cakes), fried foods (doughnuts and French fries), shortening, and margarine
Pay Attention To These Limits

1800 50-60 <14 <2
2000 55-67 <15.5 <2
2200 61-73 <17 <2
Limit Trans Fat and Saturated Fat
Choose Instead ofWhite-meat chicken or turkey without skin
Red meats and organ meats
92% lean ground beef Regular ground beef
Egg whites or egg substitute Whole eggs with yolks
Fat-free or low-fat milk and dairy products
Whole milk
Fresh fruit and vegetables with low-fat dressing or hummus
Potato chips and dip
Opt for Healthy Fats
• Replace saturated fat with monounsaturated fat to lower your LDL and increase your HDL
• Monounsaturated fats include: – Olive oil– Canola oil– Olives– Avocados– Peanut butter– Many nuts and seeds
Opt for Healthy Fats (cont’d)
• Sources of omega-3 fatty acids include:– Flaxseed– Walnuts– Salmon– Soybeans– Halibut– Shrimp– Snapper– Tofu– Etc
Opt for Healthy Fats (cont’d)
• American Heart Association recommends eating fish at least twice a week
• One serving of fish is 5 ounces (oz) (3 oz is the size of a deck of cards)
HDL (Healthy) Cholesterol Levels
• Every 1 mg/dL increase in your HDL lowers your risk of heart disease 2%-5%
HDL “Healthy” Cholesterol Levels
Men <40 mg/dLWomen <50 mg/dL
Coronary artery disease (CAD) risk
60 mg/dL or higher Protects you from CAD
Triglycerides
• Your body uses alcohol, extra calories, and sugar to produce this type of fat in the blood
Triglycerides
Less than 150 mg/dL Desirable
150-199 mg/dL Borderline high
200 mg/dL or higher High
Glucose: Why Get Tested?
• Glucose test measures the sugar level in your blood to screen for, diagnose, and monitor:– Hyperglycemia– Hypoglycemia– Diabetes– Prediabetes
Glucose: Why Get Tested? (cont’d)
• Blood glucose tests are performed:– During a regular physical– When symptoms suggest hyperglycemia
or hypoglycemia– During pregnancy– When you have diabetes– Starting at age 45 and every 3 year if
normal results
Blood Glucose
• Fasting plasma glucose: Must fast for 8 hours or longer
Plasma Glucose Results (mg/dL)
Diagnosis
99 or below Normal
100-125 Prediabetes
126 or above Diabetes
Good News!
Preventable
85%-90% of Diabetes Is Preventable
Normal Process
Insulin
Diabetes: Type 1
Diabetes: Type 2
Insulin = Fat
Hemoglobin A1c
Why get tested?• To monitor a
person’s diabetes and to aid in treatment decisions
When to get tested?
• When first diagnosed with diabetes and then two to four time per year
A1c Readin

12% 345 mg/dL
Tips to Maintain a Healthy Weight
• Do not drink calories• Eat slowly• Stay hydrated• Try the low-fat or nonfat version of foods• Change habits• Eat three meals each day• Focus on fruits and vegetables• Get enough fiber
Healthy Plate Format
• One fourth plate starch
• One fourth plate meat
• One half plate nonstarchy vegetables
• 8 fluid ounces of reduced-fat milk
• One serving of fruit
