P&P 2010 circu k

P&P 2010 compromised Circulation k

QuestionAnswer
hardening/ loss of elasticity , of arterial walls, narrowing of lumen, obstruction, ischemia/ necrosis to tissues in arterioles arteriosclerosis
presence of atheromas, on lining of any artery,(plaques : lipids, cells, fibrin & cell debris), preference for coronary arteries arteriosclerosis
tunica intima, tunica media, adventitia the laters of an artery
the build up of fatty material, cells, lipids and plaque is an atheroma:
risk of platelets adhering to rough surface. thrombus formation, obstruction leads to an embolus
atheroma also weakens wall and a ? may develop aneurysm
etiology of circulatory problems is multifactored
age (incrased risk after 40, esp. men), gender (estrogen protects, women), genetic factors that cannot be changed r/t circulatory problems
obesity,diet high in cholesterol & animal fats modifiable factors r/t circulatory problems
what leads to low hdl, high ldl, promotes platelet adhesion & vasoconstriction, decreases fibrinogen & clot formation cigarette smoking
sedentary lifestyle, poorly controlled hypertension & diabetes modifiable factors r/t circulatory problems
lipids transported with proteins are called (lipoproteins)
dangerous / “bad”, high cholesterol content, carry cholesterol from liver to cells are what kind of lipoproteins ? low density lipoproteins (ldl)
bind to vascular smooth muscle, invade wall & promote plaque fat formation low density lipoproteins (ldl)
“good”, low cholesterol content, take cholesterol away from cells to liver, excreted in the liver are what kind of lipoprotein ? high density lipoproteins (hdl)
inflammation of a vein is a phlebitis
a clot formation is a thrombus -
the presence of clots thrombosis -
traveling clot or other plug is an embolus -
inflammation of a vein, sluggish blood flow,stasis of blood, immobility, tissue injury/ trauma, increased blood coagulation are risk factors for thrombus formation
development of thrombus inside inflamed vein, clot (platelets),adhere to site,symptomatic thrombophlebitis
piece of thrombus breaks off, flows through venous circulation, flows through heart chambers is the etiology of ? an embolism
blood pressure > 140/90 is defined as hypertension
blood,volume, heart contraction, and peripheral resistance are blood pressure determinants
PRIMARY HYPERTENSION is also called Essential Hypertension
hypertension thats Idiopathic, Consistently above 140/90, Often asymptomatic until crisis is called essential/primary hypertension
Genetics / Race, Age,Gender,Diet & lifestyle,Prolonged stress are contrubuting factors to what type of hypertension essential/ primary hypertension
Damage to arterial walls, sclerosis, left ventricular hypertrophy, heart failure and/or ischemia are complications of what type of hypertension Primary/essential hypertension
aneurysm, increased risk of CVA, chronic renal failure, blindness are complications of what type of hypertension Primary/essential hypertension
Renal diseases, Endocrine disorders, CNS disorders - eg. Head injury, Gestational hypertension, are causes of what type of hypertension secondary hypertension
Uncontrollable, severe and rapidly progressive hypertension,Rapid deterioration of organs, are sings opf what type of hypertension Malignant Hypertension
*Recurrent, intermittent brief episodes of substernal pain, Tightness or pressure in chest,May radiate to neck & left arm are s/s of angina
*Pallor, Diaphoresis,*Nausea,*Restlessness / Anxiety, are s/s of angina
Stop activity, Vasodilators - e.g. nitroglycerin,Upright position,Oxygen therapy id Rx for angina
what does not cause permanent damage to the heart muscle unless frequent, prolonged & severe angina
Size and location of infarct determines what ? severity of damage
Occlusion of one of the coronary arteries secondary to, Atherosclerosis, Thrombosis, Embolus,Coronary artery stenosis or spasm, Platelet aggregation are causes of a heart attack
