ABSTRACT
Systolic blood pressure (SBP) and its association with clinical outcomes in atrial fibrillation (AF) patients in community practice are poorly characterized. In patients with AF, we sought to (1) examine the prevalence of baseline uncontrolled hypertension and the overall change in SBP control, (2) identify predictors of uncontrolled SBP over 2 years of follow-up, and (3) determine the relation between SBP and clinical outcomes. We analyzed 10,132 patients with AF at 176 clinics in the ORBIT-AF registry between 2010 and 2014, classified as: (1) no history of hypertension; (2) controlled hypertension (baseline SBP <140 mm Hg); (3) and uncontrolled hypertension (baseline SBP >140 mm Hg). Predictors of SBP >140 mm Hg at baseline or in follow-up were identified with pooled logistic regression. Random effects Cox regression models were used to compare cardiovascular outcomes and major bleeding as a function of continuous, time-dependent SBP. Overall 8,383 (83%) of patients with AF had hypertension. Of these, 24.2% (n = 2032) had uncontrolled baseline SBP, with little change over 2 years. Predictors of elevated follow-up SBP included uncontrolled baseline SBP, females, previous percutaneous coronary intervention, and diabetes. For every 5 mm Hg increase in follow-up SBP, the adjusted risk of stroke or systemic embolism or transient ischemic attack (adjusted hazard ratio [aHR] 1.05, 95% confidence interval [CI] 1.01 to 1.08, p = 0.01), myocardial infarction (aHR 1.05, 95% CI 1.00 to 1.11, p = 0.04), and major bleeding (aHR 1.03, 95% CI 1.00 to 1.06, p = 0.04) increased modestly. In conclusion, in patients with AF, higher SBP was associated with increasing adverse events; therefore, more rigorous blood pressure control should be emphasized.
