Response to Medication Registry

To create a registry/database of patients who either have taken drugs that treat cardiovascular conditions or that have presented with cardiovascular symptoms that may be related to medication. Potential enrollees are those receiving (presently or in the past) the medicine(s) of interest. Subjects will be identified from computerized Intermountain Healthcare records. Patients receiving a drug of interest, both with and without an ADE will be enrolled in approximately equal numbers. Outpatients will be contacted by mail and invited to participate. Interested subjects will be instructed to return the enclosed response card with their intent indicated. The registry coordinator will contact interested subjects and the project will be explained. Willing participants will be enrolled either in person or via mail with the assistance of the project coordinator. Persons presenting in person for enrollment will be given the choice of venipuncture or buccal swab for sample collection for DNA extraction. In all cases informed consent will be obtained before collecting samples.
