Imaging as an End Point in Ischemia Trials
Imaging of cardiac function and anatomy has advanced at an exponential rate over the past two decades. Our ability to quantitatively assess the degree of myocardial ischemia and accurately define the vascular anatomy using noninvasive techniques is greater than ever before. Current advances is cardiac imaging are allowing us to more safely assess patients for myocardial ischemia and better unde...
متن کاملQuality of life as a primary end point in oncology.
BACKGROUND In cancer clinical trials, the standard end points include response rates, progression free and overall survival, toxicity. These evaluation criteria do not measure how the cancer and its treatment affect the quality of life of cancer patients. DESIGN The relevant literature was reviewed for the purposes of determining when, how and why quality of life should be measured in cancer ...
متن کاملWhat's the (end) point?
Clinicians caring for children or adults with pulmonary arterial hypertension (PAH) face a number of challenges, not the least of which is determining whether a patient has met treatment targets based on changes in a given test (such as the 6-min walk distance (6MWD)) and whether these changes translate to meaningful improvements in that patient's quality of life or survival. While several trea...
متن کاملVariable End Point Problem
The variational derivative of a functional J[y] can be defined as δJ/δy = F y (x, y, y ′)− d dx F y ′ (x, y, y ′) [1, pp. 27–29]. Euler's equation essentially states that the variational derivative of the functional must vanish at an extremum. This is analogous to the well-known result from calculus that the derivative of a function must vanish at an extremum. In this section, we consider a sim...
متن کاملEnd-point nystagmus.
Infrared oculography was performed during sustained lateral gaze in 12 normal subjects to investigate end-point nystagmus while fixating a target light. Five failed to develop nystagmus despite deviation up to 40 degrees from 4 to 5 min. Six subjects developed nystagmus immediately or shortly after reaching the deviated position. In one, the nystagmus (0.5 degrees to 1 degree and 1.0 Hz) began ...
