After Bonferroni correction, unconditional logistic regression analyses revealed that AF risk was associated with AGT SNP7 rs3789678, compared with the non-AF heart disease control group (P = 1.28E-03, OR = 1.678, 95% CI = 1.313–2.146 for CT/CC), adjusted for age, gender, LVEF, LVEDD, LAD and frequency of hypertension and diabetes (Table 4). This evidence concerns the gene AGT and hypertensive disorder.
