摘要
Blood pressure variability is a well-known risk factor for cardiovascular disease, but its association with atrial fibrillation (AF) is uncertain. We aimed to evaluate the association between visit-to-visit blood pressure variability and incident AF. This population-based cohort study used database from the Health Screening Cohort, which contained a complete set of medical claims and a biannual health checkup information of the Koran population. A total of 8 063 922 individuals who had at least 3 health checkups with blood pressure measurement between 2004 and 2010 were collected after excluding subjects with preexisting AF. Blood pressure variability was defined as variability independence of the mean and was divided into 4 quartiles. During a mean follow-up of 6.8 years, 140 086 subjects were newly diagnosed with AF. The highest blood pressure variability (fourth quartile) was associated with an increased risk of AF (hazard ratio, 95% CI; systolic blood pressure: 1.06, 1.05-1.08; diastolic blood pressure: 1.07, 1.05-1.08) compared with the lowest (first quartile). Among subjects in the fourth quartile in both systolic and diastolic blood pressure variability, the risk of AF was 7.6% higher than those in the first quartile. Moreover, this result was consistent in both patients with or without prevalent hypertension. In subgroup analysis, the impact of high blood pressure variability on AF development was stronger in high-risk subjects, who were older (≥65 years), with diabetes mellitus or chronic kidney disease. Our findings demonstrated that higher blood pressure variability was associated with a modestly increased risk of AF.
