Exam 1 Overflow Flashcards
Causes of pulmonary hypertension
High altitude
Left to right shunts of blood flow
Left heart failure
Idiopathic
Where do deposits take place in arthersclerosis in the canine?
the tunica media
What is the agent of malignant cattarhal fever?
Ovine herpesvirus 2 is the agent of MCF
OHV-2 is consistently found in peripheral blood leukocytes and lymphoid tissues in cases of MCF in bison and cattle.
causes of thrombosis
Abnormal intimal surface
Changes in flow pattern – stasis or turbulence
Hypercoagulability, shock
What could you see on a slide with a coronary vessel thrombus?
necrosis, fibrin, inflammatory cells (macrophages), dystrophic mineralization (the purple)
Tumor cells, air bubbles, pieces
Of thrombi, bacteria can all be types of…
emboli
What type of senesitivity was discussed to be associated with vasculitis?
Type III
What sequelae can Mycobacterium avium paratubercuolsis (Johne’s Disease) in cattle cause?
Arteriosclerosis
acute heart failure (two types) and chronic heart failure
Acute heart failure:
Cardiac syncope:
Loss of consciousness due to sudden fall of blood pressure, e.g. bradycardia, MI
Peripheral circulatory failure—decreased circulating blood volume
Heart may be fine but lack of functioning blood may be the problem: shock.
Chronic heart failure: congestive heart failure
when does cardiac hypertrophy occur? what types occur with each scenario?
Occurs in volume and pressure overload
Pressure overload:
Concentric hypertrophy
Causes:
systemic and pulmonary hypertension
semilunar valve stenosis
Volume overload (increased diastolic load):
Eccentric hypertrophy
Causes:
valve insufficiencies
many cardiac defects with shunting
Systemic venous congestion and Heartworms, cardiomyopathies, some defects are a cause and effect of…
right heart failure
Aortic and mitral valve disease/ endocarditis and Lung congestion and edema is a cause and effect of…
left heart failure
true or false
left hearted failure can eventually become right hearted failure
true
is Congestive Heart Failure recompensation or decompensation?
decompensation
endiocardosis can cause…
Valve insufficiency 🡪 eccentric hypertrophy
