PG - 762-8 LID - S1071-9164(12)00806-8 [pii] LID - 10.1016/j.cardfail.2012.07.008 [doi] AB - BACKGROUND: Reverse remodeling (RR) after cardiac resynchronization therapy (CRT) is associated with favorable clinical outcomes in heart failure (HF). The renin-angiotensin-aldosterone system (RAAS) is involved in the remodeling process. METHODS AND RESULTS: We assessed the association between RR and 8 common RAAS gene variants, which were determined by TaqMan assays, in 156 outpatients with chronic HF. RR was defined as a >15% decrease in left ventricular end systolic volume (LVESV) at 9 (interquartile range 7-12) months after CRT. We matched 76 patients who did not show RR (RR-) to 80 RR+ control subjects by age, sex, HF etiology, New York Heart Association (NYHA) functional class and left ventricular ejection fraction (LVEF). The frequency of the minor allele of the NR3C2 gene (rs5522 C/T), encoding the mineralocorticoid receptor, was higher in RR- than in RR (24/126 vs 10/150; P value after false discovery rate correction: <.0193). Conversely, LVESV decreased significantly less after CRT in carriers of the NR3C2 minor C allele (P = .02). After adjustment for age, sex, NYHA functional class, previous myocardial infarction, atrial fibrillation, and LVEF, RR- remained independently associated with NR3C2 C allele carriage (odds ratio 3.093, 95% confidence interval 1.253-7.632). CONCLUSIONS: The association of RR- after CRT with a common polymorphism in the mineralocorticoid receptor gene involved in aldosterone signaling suggests a possible role for variants in RAAS genes in progressive LV function decline, despite apparently effective CRT.
