Cards

Term
What is Peripheral Artery Disease (PAD)?
Definition
Artherosclerotic disease of arteries that perfuse the limbs, esp lower extremities 
Term
What are the risk factors for PAD?
Definition

Diabetes 

Smoking 

Term
Is PAD asymptomatic or symptomatic? 
Definition
asymptomatic 
Term
What is intermittent claudication? 
Definition
  • A cramp in the muscle with ambulation due to obstruction in arterial blood flow
  • Usually comes on with activity 
Term
Where does the aorta bifurcate? 
Definition
At the Belly button 
Term
What is Atherosclerosis? 
Definition
  • A form of arteriosclerosis
  • Hardening and thickening of vessel walls "Hardening and Gruel"
  • Smooth muscle cells and collagen fibers migrate to tunica intima 
Term
What is the primary cause of CAD, cerebrovascular and PAD?
Definition
Atherosclerosis 
Term
What 3 factors affect blood flow?
Definition
  • Pressure
  • Resistance
  • Poiseuille Formular of law 
Term
What is pressure?
Definition
The force exerted on a liquid (blood) per unit area
Term
What is resistance?
Definition
Opposition to force
Term
What contribute to resistance? 
Definition
Diameter and length of blood vessels 
Term
3 components of Poiseuille Formular or Law
Definition
  • Viscosity
  • Radius
  • Length 
Term
3 characteristics of blood that affect flow
Definition
  • Velocity
  • Laminar vs. turbulent flow
  • Vascular compliance 
Term
What is considered the 2nd and 3rd heart?
Definition
The calf muscle - it has an ejection fraction just like the heart does 
Term
What is a thrombus?
Definition
Arterial blood clot attached to the vessel wall 
Term
What is an Embolus?
Definition
A blood clot that moves to another site and blocks circulation obstructing blood flow 
Term
Where are most arterial emboli from?
Definition
The heart 
Term
Arterial emboli occur secondary to what conditions? 
Definition
  • Myocardial infarction
  • Valve disease
  • Endocarditis
  • Dysrhythmias
  • Heart failure 
Term
What is the ankle brachial index test used for?
Definition
It is used to predict the severity of PAD
Term
What is the ankle brachial test formula? 
Definition
Systolic ankle pressure / Systolic arm pressure 
Term
What should the results of the Ankle brachial index test be?
Definition
  • The result should be between .9 to 1.3 
  • This means that your blood pressure in your ankle and your arm should be about the same 
  • This would indicate that you do not have PAD of blockage of flow 
Term
What is arterial bypass?
Definition
  • It treats narrowed arteries bu creating a bypass around a section of an artery that is blocked
  • This new pathway is created with a graft 
Term
Types of vein grafts 
Definition
  • In situ
  • Reversed
  • Composite
  • Saphenous Vein 
  • Biosynthetic (man made)
Term

What is Buerger's Disease

thromboangiitis Obliterans?

Definition
  • An inflammatory disease of peripheral arteries resulting in nonatherosclerotic lesions
  • It obliterates the small and medium sized arterise  
Term
Who is most effected by Buerger's Diease? 
Definition
  • Young men
  • Smokers
Term
Clinical manifestations of Buerger's Disease
Definition
  • Pain
  • Tenderness
  • Hair loss in affected area
  • Can often lead to gangrenous lesions
Term
What are the symptomes of Buerger's Disease caused by?
Definition
Slow, sluggish blood flow 
Term
What is Raynaud Disease?
Definition
  • Episodic vasospasm (ischemia) in arteries and arterioles of the fingers 
  • (less common in toes)
Term
What triggers Raynaud's Disease?
Definition
Cold 
Term
What is Raynaud Phenomenon?
Definition
  • Secondary to other systematic diseases of conditions
  • Collagen vascular disease
Term
What are risk factors for Raynaud Phenomenon?
Definition
  • Smoking
  • Pulmonary hypertension
  • Myxedema
  • Envoiornmental factors 
  • Cold
  • Vibrating machinery 
Term
What is the color change that occurs with Raynauds Disease?
Definition
  • Red 
  • White
  • Blue 
Term
Examples of Coronary Vessels 
Definition
  • Coronary Capillaries
  • Coronary Veins
  • Coronary lymphatic vessels 
Term
Preload, afterload, and contractility effect?
Definition
Stoke volume
Term
Cardic output = ?
Definition
Stroke volume X heart rate 
Term
What is a deep vein thrombosis (DVT)?
Definition
  • Obstruction of venous flow
  • Leads to increaded venous pressure
Term
What 3 things cause a DTV?
Definition

Virchow's Triad

  • Venous stasis
  • Endothelial damage
  • Hypercoagulable states (consistency of blood)
Term
What is post thrombotic syndrome?
Definition
A term used to describe signs and symptoms that may occur long term after a patient has had a DTV
Term
Thrombus
Definition
Blood clot that remains attached to the vessel wall
Term
Embolus
Definition
  • Blood clot that moves to another site
  • Blocks circulation causing an obstruction in blood flow
  • Pulmonary embolism 
Term
What are some symptomes of Post thrombotic syndrome?
Definition
  • Chronic swelling
  • Stasis dermatitis
  • Venous ulcers 
Term
What is a varicose vein?
Definition
  •  A vein with pooled blood
  • Distened, tortuous, and palpable veins 
Term
What are varicose veins caused by?
Definition
  • Trauma
  • Gradual venous distention 
Term
What is chronic venous insufficiency?
Definition
Inadequate venous return over a long period of time
