Pathology of Heart and Blood Vessels Flashcards
(49 cards)
Aneurysm is usually an
artery
Common sites for aneurysm are
thoracic and abdominal aorta
vessels in brain
Causes of aneurysms can be
chronic HTN, connective tissue disease, trauma, infection
Aortic aneurysms are usually asymptomatic but can include..
generalized abdominal and/or LBP
Abdominal aortic aneurysms can cause
pulsations near navel
Cerebral aneurysm can cause sudden
and severe HA, N/V, stiff neck, seizure, loss of consciousness and double vision
Prinzmetal angina
occurs due to coronary artery spasm
S/s of angina
pressure, heaviness, fullness, squeezing, burning or aching behind sternum.
Can also be felt behind neck and back, jaw, shoulders, and arms.
Associated with difficulty breathing, N/V, sweating, anxiety and/or fear
In atherosclerosis, when coronary arteries are affected, what may result?
When cerebral arteries are affected, what may result?
When peripheral arteries are effected, what may result?
angina pectoris
N/T, weakness of arms and legs, slurred speech, or drooping face.
intermittent claudication
In dilated cardiomyopathy, what is often needed?
Hypertrophic?
Resrictive?
pacemaker or implanted defibrillator
medications to slow HR and stabilize rhythm
heart transplant in severe cases
Chronic venous insufficiency is characterized by?
veins remaining filled with blood due to weak or damaged valves inside veins
Atrial septal defect (ASD)
hole between R and L atria called a shunt if persists
Coarctation of aorta
congenital defect where the aorta is narrowed near ductus arteriousus
usually occurs with other defects, could not be detected until adulthood.
S/s of coarctation of aorta
HBP in arms but L blood pressure in legs
Patent ductus arteriosus (PDA)
ductus arteriosus (normally shunts blood from pulmonary artery directly to descending aorta in utero) does not close after birth.
Ventricular septal defect (VSD)
hold in septum separating R and L ventricles
too large of a hole and the blood will be pumped into lungs leading to HF
Tetralogy of Fallot
combo of 4 heart defects: VSD, pulmonary stenosis, R ventricular hypertrophy, aorta overriding VSD
diagnosed in infancy but may not be detected until later in life.
only effective treatment is surgery
Cor Pulmonale
pulmonary heart disease
happens there is hypertrophy of RV caused by altered structure or function of lungs.
Cause of cor pulmonale
pulmonary HTN from chronically increased resistance in the pulmonary circulation
Cardinal symptom of cor pulmonale
progressive SOB especially with exertion
Supplemental O2 for Cor pulmonale
> 90% SaO2 and/or PaO2 >60 mmHg
CAD is the diminished blood flow that may cause angina, SOB etc which may not be felt until ___% occluded. Complete blockage causes..
70
heart attack
Clinical prediction rules for DVT:
active cancer or previous 6 months
paralysis, paresis or immobilization of LE
bedridden >3 days or major surgery in last 12 weeks
Localized tenderness on posterior calf, popliteal space, femoral vein
entire LE swelling
unilateral calf swelling >3 cm
Unilateral pitting edema
previous DVT
Scoring on clinical prediction rules for DVT:
<1 point =low risk
1-2 points=moderate risk
>2 points=high risk
new scoring:
>1 likely
<1 unlikely
