Genetic Risk Factors
Determined by genes
 Congenital disease is present at birth



Others don’t show up until later in life
Familial Disease Tendency

Disease runs in family
Genetic Risk Factors

Recessive gene
disorders
Need recessive gene from
both parents
 Can be a carrier
 Cystic fibrosis & sickle cell
anemia


Down syndrome

Born with extra
chromosome
Genetic Risk Factors

Sex-linked disorders
Linked to x chromosome
(female)
 Can be recessive in females
 Color blindness, hemophilia,
& muscular dystrophy


Blood
Types of CV Disease
Hypertension

 Heart Valve Disorder
 Varicose Veins

Hypertension
High Blood Pressure
 Normal=120/80
 Over 120/80= At risk
 High=150/90
 Thickening of blood vessel walls
 Narrows passageways for blood
 https://youtu.be/-di2R51QcqE

Arteriosclerosis
Hardening of the
arteries
 Narrows blood
vessels & blocks
blood flow
 Atherosclerosis


Fat deposits in
blood vessels
Heart Attack
Caused by lack of oxygen delivery to cells
 Coronary heart disease

Blockage of coronary arteries
 Caused by fat deposits and/or blood clots
 Causes heart attack


Cardiac Arrest

Entire heart stops
Stroke
Disrupts blood flow to brain
 No oxygen to brain
 Brain cells die
 Caused by fatty deposits, blood clots, or
burst arteries
 Aneurysm


Weak spot in blood vessel that can burst
Stroke

Effects
Speech
 Senses
 Movement
 Memory
 Behavior
 Depending on side
of the brain

Heart Valve Disease
4 valves in heart
 2 between atria & ventricle
 2 between heart & arteries
 Bypass Surgery

Arrhythmias &
Varicose Veins
Arrhythmias
 Abnormal
heart beat
 Pacemaker
 Defibrillator
Varicose Veins
•Large blue
veins
•One-way
valves don’t
work
Testing & Diagnosis

Electrocardiogram (ECG/ EKG)


Stress Test


Graphs electrical impulses and heart beats
ECG during exercise
Chest X-Ray

Picture of heart
