Title: Cardiovascular Disease


1
Cardiovascular Disease
  • Heart Disease and Hypertension


2
Coronary Heart Disease
  • Statistics
  • 1 killer in US
  • 50 of deaths in US
  • Major cause of deaths worldwide

3
Heart Disease, continued
  • Course
  • Atherosclerosis (mushy to harden) mounds of
    soft lipids (TG, Cholesterol, calcium)? plaque
  • Plaque accumulates? narrowing blood vessels?
    increase BP? more strain on heart
  • Plaque? vessel walls rougher? more fat and
    cholesterol deposited

4
Heart Disease, continued
  • Course continued
  • Complete occlusion vessel
  • Clot breaks away travels and blocks coronary
    arteries of the heart/cerebral capillaries
  • Heart attack restricted blood flow to heart
  • Stroke restricted blood flow to brain

5
Heart Disease Risk Factors
  • Age, Gender, Family History Men 45 Women
    55
  • High Cholesterol ( High LDL Low HDL)
  • Hypertension
  • Diabetes
  • Obesity Physical Inactivity
  • Cigarette Smoking

6
Heart Disease Risk Factors, cont
  • Metabolic Syndrome ( 3 of the following)
  • Abdominal obesity waist circumference 40 in
    (men) or 35 inches (women)
  • Triglycerides 150 mg/dl
  • HDL
  • Blood pressure 130/85
  • Fasting glucose 100 mg/dl

7
Reducing Heart Disease Risk
  • Healthy Eating Pattern
  • Healthy Body Weight
  • Desirable Blood Cholesterol Lipoproteins
  • Desirable Blood Pressure
  • Physical Activity

8
Decreasing Risk Diet
  • Consume complex carbohydrate rich foods
  • Soluble fiber Oats, Barley, Pectins (Fruits,
    some vegetables
  • Legumes
  • Variety of fruits, vegetables, whole-grain
    products

9
Diet, Continued
  • Decrease total fat 20 -35 of total calories
  • Diet low in saturated fat, trans-fat, and
    cholesterol
  • Cholesterol -
  • Saturated fats -
  • Trans-fats -

10
Diet, continued
  • Cholesterol
  • Found only in animal products
  • Highest in egg yolks, organ meats
  • Whole dairy products
  • Beef, pork, lamb

11
Diet, continued
  • Saturated Fats, Trans fats
  • Coconut, Palm, and Palm kernal oils
  • Sausage, bacon, luncheon meats,
  • Whole milk, butter, regular cheeses, ice cream
  • Hydrogenated foods

12
Dietary Strategies
  • Omega-3 fatty acids (fatty fish) 2 x week
  • Alcohol in moderation
  • Soy Protein

13
Hypertension-The Silent Killer
  • Definition
  • High blood pressure
  • HTN
  • 140/90
  • Normal systolic 100-120 (heart beating)
  • Normal diastolic 60-80 (heart relaxed)
  • Prehypertension 120-139/80-89

14
HTN-continued
  • HTN- most common type of CVD
  • 1/2 million strokes
  • 1 million heart attacks
  • Affects 60 million people in US
  • 1/3 of population
  • Obesity and atherosclerosis contribute to HTN
  • Risk increases greatly with age

15
Hypertension-The Silent Killer
  • Heart pushes blood through arteries into
    capillaries
  • Peripheral resistance pushes O2 and nutrients
    into cells
  • Cardiac output increases, increasing work of heart

16
HTN Risk Factors
  • Age risk increases with age
  • Genetics family history
  • Obesity 60 of those with HTN are obese
  • Salt sensitivity
  • Alcohol

17
HTN Prevention/Control
  • Weight control one of most effective tx
  • Physical activity
  • Moderate use ETOH
  • Limit sodium intake (2400 mg/day)
  • DASH Eating Plan Plenty of fruits/vegs low fat
  • Medications prescribed by MD

18
DASH Diet Dietary Approaches to Stop
Hypertension
