Increased stroke volume, increased systolic pressure and decrese diastolic pressure, hence increase plulse pressure, So A???

Yes, I also think its A)

Didn't really need the picture because BP is given, HR is given, so you could just work it out from there...

the ans is A in diastole blood drops back into ventricle so decrease in diastolic press n increase pulse pressure the volume in left ventricle increases so increase in stroke volume increase in systolic pressure

Answer is A)
In AR there is increase in Blood pressure and pulse pressure..there is increase in stroke volume but ejection fraction may be same or it may decrease.

A?
AR - more backflow into the LV during diastole, eventually more being pushed out in systole (increased SV). So increased BP. and wide pulse pressure.

Ans is D
PP- Up (due to rise in systolic pressure and fall in diastolic pressure)
Systolic pressure is up it's given in the question
stroke volume is down- (stroke volume = EDV-ESV) due to aortic regurge ESV will go up

Correct Answer correct answer

The correct answer is A)

The difference between systolic pressure and diastolic pressure is the pulse pressure. The two major factors that affect pulse pressure are the SV output of the heart and the compliance of the arterial tree. In patients with AI, the blood that is pumped into the aorta immediately flows back into the LV. The backflow of blood into the LV increases SV and systolic pressure. The rapid backflow of blood also results in a decrease in diastolic pressure. Thue, patient with moderate AI have high systolic pressure, low diastolic pressure and high pulse pressure.

@axax, remember that EDV will also increase!

Help Aortic stenosis

I read that aortic stenosis is associated with low (narrow) pulse pressure, can someone explain to me the reason ?
Isn't it supposed to be associated with a high (wide pulse pressure) since less blood volume in aorta during diastole (low diastolic pressure) and more pressure is required to open the stiff valve during systole thus higher systolic pressure !!!
