Background

To clarify the influence of hypertension and blood pressure (
BP
) control on thromboembolism and major hemorrhage in patients with nonvalvular atrial fibrillation, a post hoc analysis of the J‐
RHYTHM
Registry was performed.

Methods and Results

A consecutive series of outpatients with atrial fibrillation was enrolled from 158 institutions. Of 7937 patients, 7406 with nonvalvular atrial fibrillation (70.8% men, 69.8±10.0 years) were followed for 2 years or until an event occurred. Hypertension was defined as a systolic
BP
≥140 mm Hg, a diastolic
BP
≥90 mm Hg, a history of hypertension, and/or antihypertensive drug use. Hypertension was an independent risk factor for major hemorrhage (hazard ratio 1.52, 95%
CI
1.05–2.21,
P
=0.027) but not for thromboembolism (hazard ratio 1.05, 95%
CI
0.73–1.52,
P
=0.787). When patients were divided into quartiles according to their systolic
BP
at the time closest to the event or at the end of follow‐up (Q1, <114; Q2, 114–125; Q3, 126–135; and Q4, ≥136 mm Hg), odds ratios for both events were significantly higher in Q4 than in Q1 (thromboembolism, odds ratio 2.88, 95%
CI
1.75–4.74,
P
<0.001; major hemorrhage, odds ratio 1.61, 95%
CI
1.02–2.53,
P
=0.041) after adjustment for components of
CHA
2
DS

‐
VAS
c score, warfarin use, and antiplatelet use. A systolic
BP
of ≥136 mm Hg was an independent risk factor for thromboembolism and major hemorrhage.

Conclusions

BP
control appears to be more important than a history of hypertension and baseline
BP
values at preventing thromboembolism and major hemorrhage in patients with nonvalvular atrial fibrillation.
