rs880054 of WNK1 was significantly associated with SBP (p-value = 0.027), glyceride level (p-value = 0.026), weight (p-value = 0.024), IHD (p-value = 0.039), cerebrovascular accident (p-value = 0.02), and atrial fibrillation (p-value = 0.02). This evidence concerns the gene WNK1 and myocardial ischemia.
