Study Summary

We hypothesize that b2 adrenergic polymorphisms affect b-receptor selectivity in patients with heart failure treated with either a b1-selective or a b-nonselective agent. b-2 polymorphisms may contribute to differing responses to drug treatment with beta-blockers in heart failure. Characterizing these polymorphisms may help explain the variability in the degree of "selectivity" of action of b-blockers at the b receptor, namely if their action is specific for the b-1 or b-2 receptor. Part A was conducted at the University of Utah, and all subjects completed study related activities. Part B (sub-study) consists of genotyping of blood samples collected in part A, which will be completed at the University of Wisconsin. Sub-study (samples and DNA isolation) or Part B entailed analyzing an extra 10 mL of blood that was taken for DNA isolation. Genotyping (i.e. determination of genetic makeup) of beta adrenergic polymorphisms utilized polymerase chain reaction followed by pyrosequencing.
