Abstract

Although many studies have suggested the association between elevated blood pressure and atrial fibrillation (AF), how the relationship between systolic blood pressure (SBP) and AF differ by antihypertensive treatment has been unclear. Therefore, this study aimed to explore the relationship between SBP and AF in hypertensive patients with or without antihypertensive treatment. This was a cross-sectional study that enrolled 7,808 hypertensive patients aged ≥18 years old in 2013 in Guangdong, China. AF was screened and diagnosed by rest 12-lead electrocardiogram (ECG) or by self-reported. Patients were categorized into 5 groups according to a 10 mmHg increment in SBP. We then performed logistic regression and restricted cubic spline regression to evaluate the relationship between SBP and AF. Out of 7,808 participants (women 52.9%, mean age 62.3 years), 78 cases of AF were identified. Both univariate and multivariate logistic regression illustrated that SBP associated with a lower chance of AF in all participants when SBP was treated as a continuous variable (P<0.05) or as a categorical variable (P for trend <0.001). Similar trend was found in patients with antihypertensive therapy (P for trend <0.001) but not for those without an...Continue Reading

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
