The purpose of this research is to test whether participating in either a physical activity intervention or a series of educational classes will help to preserve exercise capability, heart function, brain-based activities (like memory), and quality of life. Participants will be randomized to 1 of 2 pathways: - First pathway consists of organized health workshops. These workshops are intended to provide information on topics such as proper nutrition, management of stress, sleep practices, and emphasis on a healthy lifestyle that may help the participants through cancer treatment. This pathway will also test whether stretching may help participants through cancer treatment. - Second pathway participants will take part in some unsupervised and some potentially supervised moderate activity sessions each week throughout participants' cancer treatment to take place either remotely or in person, depending on availability of facilities at the time visits are scheduled.
The study develops software for motion analysis and assessment of cardiac function for cardiac images. Cardiac catheterization ventriculography of several randomly selected patients were taken from our hospital's PACS system. The investigators remove the patient information on the images, and use the image for motion analysis and assessment.
The purpose of the study is to directly compare two methods of evaluating heart function at the time of your angiogram. In both methods contrast dye is injected into the main heart chamber during the angiogram while x-ray images are taken. One method uses an automatic power injector to deliver the normal volume of contrast; the other method uses hand injection of very low volume of contrast into the main heart chamber. It is hypothesized that hand injection will prove to be an accurate method to estimate ejection fraction (EF) at the time of radial coronary angiography when compared directly to Power LV.
