High Pretreatment PSA Velocity Predicts Worse Outcome
The most significant single predictor of aggressive prostate cancer is an elevated rate of increase in prostate specific antigen (PSA) levels, according to a new study. The study found that a pre-treatment rate of PSA increase, called PSA velocity, of more than 2 ng/ml/year was strongly associated with a high risk of death from prostate cancer. Elevated PSA velocity was a stronger poor prognosti...SphygmoCor Vx Central Blood Pressure/Pulse Wave Velocity System
Description:SphygmoCor Vx Central Blood Pressure/Pulse Wave Velocity System is an add-on package to the Px System. The Vx system enables the measurement of the velocity of the pressure wave along a specific arterial segment. The velocity of the pressure wave along the artery is dependent upon the stiffness of the artery. This system is most commonly used to measure the aortic pulse wave velocity, by taking...
