Control Weight and Waist Circumference
Weight
Overweight teens have high risk of diabetes and heart disease in future

Waist Size
Subcutaneous fat and visceral fat are dangerous
Avoid waists of: 40 inches for men 30 inches for women Potbelly with normal weight
Physical Activity Decreases Risk
All Least fit are at greater risk of death
MenMore rigorous exercise = greater protection and longevity
Women
30 minutes/day of moderate activity lessens risk
Fitness more important than overweight or obesity in cardiometabolic risk
Smoking Is The Most Significant Risk Factor
Causes over 250,000 deaths per year
Causes peripheral arterial disease
Active and passive smoking
Accelerate artery clogging Increase risk of developing coronary heart disease
Control Blood Sugar To Decrease Risk
Check your blood sugar to see if you are at risk

Heart Anatomy
Heart Anatomy
• Blood moves through aorta to brain and body
Overview Of Blood Flow Through Heart
• Blood from body moves into right atrium
Right Atrium Contracts
• Blood moves into right ventricle
Right Ventricle Contracts
• Blood moves to lungs and then pulmonary vein
Left Atrium Contracts
• Blood moves into left ventricle
Left Ventricle Contracts
How Blood Flows Through Body
Understanding The Heart
Myocardium Heart muscle
Pericardium2-layer membrane surrounding heart
Lubricant between layers allows heart muscle to move freely
Systole Contraction of heart
DiastolePeriod between contractions when heart fills with blood
CapillariesSmallest blood vessels in body
Deliver oxygen via the blood and take up waste
Cardiovascular Risk Factors
Education Low education level at higher risk
Stress
Chronic = plaque & high blood pressure
Episodic = creates unstable plaque
Acute = trigger heart attack
DepressionDepression and heart disease are linked
Depressed women more likely to have heart attack
Anger Angry men at much higher risk
Cardiovascular Risk Factors Continued
CRPC-Reactive protein signals inflammation
Increased CRP increases risk
Homo-cysteine
May influence atherosclerosis
Illegal Drugs
Sudden increases in blood pressure
Left ventricular contraction
Irregular heart rhythms
Bacterial Infection
Streptococcus and chlamydia
Tips For Women To Avoid Heart Disease
Abstain from smoking
BMI less than 25
Exercise 150 + moderate or 75 + vigorous minutes each week week
Eat 4 + components of healthful
Non-HDL cholesterol less than 230
Blood pressure below 120/80
Fasting blood sugar below 100
Heart Disease Symptoms Different In Women
Pay attention to these early signs of disease
Pain in back, between shoulders
Sick to stomach
Feeling scared or nervous
Pain in belly above belly button
New or worse headaches
More Symptoms In Women
Tiredness, even after getting enough sleep
Trouble breathing
Trouble sleeping
Ache in chest
Chest feeling ‘heavy’ or ‘tight’
Burning feeling in chest
Pain or tightness in chest that spreads
Aspirin Is Recommended For Some
Aspirin may reduce heart attack risk, but may also increase bleeding
Aspirin decreases clotting risk, but increases bleeding risk
Must consider risk of gastrointestinal bleeding when choosing to take aspirin
Men 45 to 79 to reduce risk of heart attack
Women 55-70 to reduce risk of stroke
Heart Health Conditions
Coronary Artery DiseaseArteriosclerosis – degeneration and hardening of arterial walls
Atherosclerosis – arteriosclerosis plus plaque deposits on walls of arteries
Heart Conditions
Angina PectorisDue to brief lack of oxygen to heart
Severe, suffocating chest pain
Heart Attack / Myocardial InfarctionWhen portion of heart does not receive oxygen and begins to die
Cardiac Arrest
Heart stops beating
Symptoms Of A Heart Attack
30 minutes or more of chest pain that is not relieved with 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
If experiencing heart attack symptoms, take 325 mg of aspirin and seek immediate
medical attention
If experiencing heart attack symptoms, take 325 mg of aspirin and seek immediate
medical attention
Cardiac Arrest
CPRCardio-pulmonary resuscitation
Combining rescue breaths with chest compressions creates circulation
AED
Automatic External Defibrillator
Portable device available in most public places can restart a heart that has a lethal rhythm
ActionControl with diet, exercise and possibly medication
Cerebrovascular Accident Explained
Defined‘Stroke’ occurs when blood supply to brain in blocked
TypesIschemic – blockage of flow by cerebral thrombus or cerebral embolism
Hemorrhagic – blood vessels rupture
TIA
Transient Ischemic Attack
Little strokes with minimal damage
Doubles risk of heart attack
Cerebrovascular Accident Risk
Risk Factors
Women, especially during hormonal changes
