What Causes Heart Disease/Stroke?

• Arteries—blood vessels that carry blood away from the heart to the rest of the body

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

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

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
