no body wanna try this question????

increases, increases and increases...???

INCREASE IN REGURGITANT STOKE VOLUME
DECARESE IN LV FORWARD STROKE VOLUME
DECRAESE IN CARDIAC OUTPUT






LEFT VENTRICULAR AFTER LOAD IS ALREADY INCREASED IN AORTIC REGURG AND IS ASSOCIATED WITH GREATLY INCREASED LV TOTAL STROKE VOLUME AND WIDENED PULSE PRESSURE...A FURTHER INCREASE IN AFTER LOAD WOULD INCREASE THE REGURGITANT STROKE VOLUME AND FURTHER DECREASE THE LV FORWARD STROKE VOLUME THEREB Y FURTHER REDUCING THE CARDIAC OUPUT.THIS IS WHY MEDICAL STABILIZATION OF PATIENTS WITH SEVERE ACUTE AORTIC REGURG MAY INCLUDE ADMINSTARTION OF VASODILATORS( NITROPRUSSIDE) IN ADDITION TO INTRAVENOUS POSITIVE INOTROPIC AGENT(DOPAMINE,DOBUTAMINE).THE VASODIALTORS DECREASES AFTER LOAD IN ORDER TO IMPROVE FORWARD STOKE VOLUME.
