1/20

which diseas results in pressur overload of right ventricle?

pulmonary regurgitation
pulmonary stenosis
tricuspid regurgitation
mitral stenosis
2/20

the character of concentric hypertrophy is?

the numers of myocardial cells increase
sarcomere increased in series
sarcomere increased in parallel
increased of the myocardial cell length
3/20

which is wrong about the describe of myocardial hypertrophy?

myocardial size increased in myocardial hypertrophy
total contractility of heart increase
myocardial hypertrophy may prevent the happen of
heart failure
myocardial hypertrophy may present in chronic heart
failure
4/20

which diseas leads to concentric hypertrophy of left ventricle?

pulmonary hypertension
aortic stenosis
aortic regurgitation
mitral regurgitation
5/20

blood volume is increased in chronic heart failure due to?

pulmonary congestion
increased of CVP
redistribution of blood
water and sodium retention and increased of RBC
6/20

which compensatroy mechanism won't happen in acute heart failure?

increased of heart rate
myocardium hypertrophy
increased activity of sympathetic nervous system
redistribution of blood
7/20

mitral regurgitation results in?

evident left ventricular chamber dilation
evident increased thickness of left ventricular wall
the sarcomere increase in parallel
evident increase of myocardial cellular diameter
8/20

Congestion heart failure refers to?

chronic heart failure in which the blood volume and
intestitial fluids is increased
heart failure that characterized as ventricle dilated
heart failure that characterized as blood pressure
decreased
heart failure that characterized as pulmonary
congestion and edema
9/20

which is better to access the myocardial contractility decreased?

decreased of blood pressure
decreased of cardiac output
increased of heart rate
pulmonary congestion and edema
10/20

which diseas results in volume overload of left ventricle?

aortic stenosis
aortic regurgitation
hypertension
tricuspid regurgitation
11/20

the character of eccentric hypertrophy is?

the numers of myocardial cells increase
sarcomere increased in series
sarcomere increased in parallel
increased of the myocardial cell length
12/20

the most common manifestation of left heart failure is?

hepatic congestion
dyspnea
ascites
edema of lower limb
13/20

aortic stenosis leads to left ventricular?

pressure overload
volume overload
chamber dilation
evident increase of myocardial cellular length
14/20

which is the cause of myocardial failure?

hypertension
aortic regurgitation
aortic stenosis
myocardial infarction
15/20

aortic regurgitation results in?

volume overload of the left ventricle
volume overload of the right ventricle
pressure overload of the right ventricle
pressure overload of the left ventricle
16/20

which disease results in cardiogenic shock often?

mitral regurgitation
aortic regurgitation
hypertension
acute myocardial infarction
17/20

the major mechanism resulting in heart failure in patient with myocardial infarction is?

myocardial structure injury
disorders in utilization of energy
disorders in liberation of energy
dysfucntion of excitation contraction coupling
18/20

the major mechanism of pulmonary edema results from acute left heart failure is?

high cardiac output and increased pulmonary blood
perfusion
increased permeability of pulmonary capillary
increased hydrostatic pressure of pulmonary capillary
decreased plasma osmotic pressure
19/20

the disease that may leads to high cardiac output heart failure is?

severe anemia
coronary heart disease
cardiomyopathy
mitral stenosis
20/20

eccentric hypertrophy of myocardium is manily results from?

water and sodium retention
increased of blood volume
volume overload for a long time
pressure overload for a long time
