title: Diuretic-gene interaction and the risk of myocardial infarction and stroke.
abstract: This study investigates whether the interaction between diuretics and alpha-adducin (ADD1) G460W or G-protein beta3-subunit (GNB3) rs2301339 polymorphism modifies the risk of myocardial infarction (MI) or stroke. Data were used from the Rotterdam Study. The drug-gene interaction was determined with a Cox proportional hazard model with adjustment for each drug class as time-dependent covariates. The risk of MI in current users of low-ceiling diuretics with one or two copies of the ADD1 W-allele (hazard ration (HR)=0.92) was similar compared to the expected joint effect of the W-allele and low-ceiling diuretics on a multiplicative scale (1.04 x 0.90=0.94) (synergy index (SI):0.99; 95% confidence interval (CI): 0.43-2.27). No drug-gene interaction was found on the risk of stroke (SI:0.66; 95% CI:0.43-1.27). In addition, a trend towards an interaction was found between current use and the GNB3 rs230119 G/A polymorphism on the risk of MI (SI: 0.51; 95% CI: 0.23-1.15), whereas no interaction on the risk of stroke was found (SI: 0.84; 95% CI: 0.46-1.56).
