G-Protein Beta-3 Subunit Genotype Predicts Enhanced Benefit of Fixed-Dose Isosorbide Dinitrate and Hydralazine: Results of A-HeFT | Journal Scan

Study Questions:

Was there an influence of the guanine nucleotide-binding proteins (G-proteins) beta-3 subunit (GNB3) genotype on the effectiveness of a fixed-dose combination of isosorbide dinitrate and hydralazine (FDC I/H) in the A-HeFT study (African American Heart Failure Trial)?
