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

aortic stenosis leads to left ventricular?

pressure overload
volume overload
chamber dilation
evident increase of myocardial cellular length

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

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

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

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

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

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

which diseas leads to concentric hypertrophy of left ventricle?

pulmonary hypertension
aortic stenosis
aortic regurgitation
mitral regurgitation

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

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

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

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

the most common manifestation of left heart failure is?

hepatic congestion
dyspnea
ascites
edema of lower limb

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

which is the cause of myocardial failure?

hypertension
aortic regurgitation
aortic stenosis
myocardial infarction

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

severe anemia
coronary heart disease
cardiomyopathy
mitral stenosis

which diseas results in volume overload of left ventricle?

aortic stenosis
aortic regurgitation
hypertension
tricuspid regurgitation

which disease results in cardiogenic shock often?

mitral regurgitation
aortic regurgitation
hypertension
acute myocardial infarction

which diseas results in pressur overload of right ventricle?

pulmonary regurgitation
pulmonary stenosis
tricuspid regurgitation
mitral stenosis
