Details and patient eligibility

About

Patients enrolled in this study will have completed one of the parent studies "Pharmacogenomic Evaluation of Antihypertensive Responses" (PEAR-1 or PEAR-2) evaluating how well their blood pressure was controlled by medication. Patients in the current study will provide a single tube of blood which will be used to create adult stem cells that can be converted into other cell types, like heart or vasculature. Patients will not be asked to return for any follow up visits.

Full description

If the patient decide to participate in this study, they will have 1 visit for the study that will include a blood draw. Upon arrival to the clinic, the study will be explained to the patient in detail. The patient will be asked at that time to sign this consent form. The patient will have the opportunity to ask questions and the research staff will answer those questions. If the patient decides to participate in this study and sign a consent form, then a blood sample will be collected from a vein in the arm. A total of 2 teaspoons full of blood will be drawn for the study.

During this visit, in addition to collecting a blood sample, patients will be asked about their medical history and medications they are currently taking, and will have their vital signs assessed, including blood pressure, pulse, and temperature.

Blood will be drawn by a trained nurse or a phlebotomist at a family medicine clinic in Gainesville, Florida. The blood sample will be further processed in laboratories at the University of Florida, for the establishment of iPS cells. iPS cells will retain the patient's genetic makeup which makes them useful for research. Several experiments will be conducted on these cells that will provide data that can be used to learn more about how genetic markers can lead to differences in blood pressure response to medicines. These cells will be used for up to 8 years.
