Abstract

The association between sustained pre-hypertension and atrial fibrillation (AF) has not been thoroughly examined. This study included 5311 participants (mean age 62 ± 10 years; 47% male; 42.9% non-whites) from the Multi-Ethnic Study of Atherosclerosis. Sustained exposure was based on 2 or more visits within the same blood pressure category (optimal, <120/80 mm Hg; pre-hypertension, 120-139/80-89 mm Hg; hypertension, ≥140/90 mm Hg or antihypertensive medication use) during visits 1, 2, and 3. Cox regression was used to compute hazard ratios (HR) and 95% confidence intervals (CI) for the association between blood pressure category and AF. Over a median follow-up of 5.3 years, 182 (3.4%) participants developed AF. Pre-hypertension and hypertension were associated with an increased risk of AF compared with participants who had optimal blood pressure (optimal: HR, 1.0; referent; pre-hypertension: HR, 1.8; 95% CI, 1.004-3.2; hypertension: HR, 2.6; 95% CI, 1.6-4.4). Sustained pre-hypertension is associated with an increased risk of AF.
