Blood flow in arteries and veins depends on
|
Patency of blood vessels; adequate perfusion pressure
|
If disturbance in blood flow, then disruption of
|
Oxygen delivery, removal of wastes; return of blood to heart
|
Arterial disorders
|
Decrease blood flow to tissues; impaired delivery of oxy and nutr.
|
Venous disorders
|
Interferes with outflow of blood from capilaries, removal of tissue wastes,return of blood to heart
|
Cholesterol panel
|
Desirable at :less than 200; borderline high @ 200-239; high at greater or equal 240
|
Types of Liproproteins and levels
|
HDL: good; has to be greater than 40; LDL less than 100; VLDL
|
Hypercholesterolemia
|
High cholest. in blood due to too much calorie;sat.fats/transfats;cholesterol
|
Types of hypercholesterolemia
|
Primary (hereditary); secondary (associated to other health prob. HTN)
|
Major risk factors of coronary heart disease due to high hyperlipidemia
|
Age (men over 45, wom.over55), famil. (premature CHD in first degree relative;ex father); HDL (less than 40), smoking,HTN
|
Management of hyperlipidemia
|
Stop smoking;lose weight(BMI less 25);less sat.fats and chol; exercise;monitor BP and lipids;teaching
|
Xanthomas
|
Outward appearance of hyperlipidemia (fat builds up on eye,finger,knees);
|
Atherosclerosis
|
Chronic inflammatory response in walls of arteries; plaques builds up on inside of arteries; thickening and hardning
|
Clinical manifestations of artherosclerosis
|
Narrow vessels:ischemia; sudden vessel obstruction due to plaque hemo. or rupture; thrombis and emboli; aneurysm
|
Major complications of atherosclerosis
|
Ischemic heart attack (MI); stroke (brain attack); PVD
|
Signs and symptoms of acute arterial occlusion
|
Disease of extremeties; no pulse, cap.refill less than 3 sec; palor; pain
