GenHAT - Genetics of Hypertension Associated Treatments - Ancillary to ALLHAT
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
High blood pressure is one of the most common health problems in the United States. There are many medications to treat high blood pressure, but there is a large variance in how people respond to these medications. It is believed that genetic variations may contribute to the inconsistent treatment response. This study will use genetic analysis to determine whether particular genes interact with high blood pressure medications to modify the risk of certain cardiovascular diseases.
