Abstract

Background

Arterial stiffness, measured using carotid-femoral pulse wave velocity (c-f PWV) and heart rate-corrected augmentation index (Aix75), is associated with cardiovascular disease, and in some studies incident atrial fibrillation (AF). In this cross-sectional study, we aimed to investigate whether arterial stiffness is associated with markers of atrial myopathy, which refers to structural and electrical changes in the atria that indicate increased AF risk.

Methods

We included 1050 participants (age 57 ± 4.3 years, 47% males) from the population-based Swedish CArdioPulmonary bioImage Study with c-f PWV and Aix75 data. A random subsample (n = 331) underwent echocardiography. The association between arterial stiffness and atrial myopathy markers was studied using multivariable-adjusted negative binomial regression models for premature atrial complexes (PACs) on 24 h ECG, linear regression for P-wave duration and left atrial volume index (LAVi), and logistic regression models for abnormal P-wave terminal force in V1 (PWTFV1) and P-wave axis.

Results

Arterial stiffness was associated with fewer PACs: incidence rate ratio (IRR) 0.45 (95% CI: 0.31 to 0.65, p < 0.001) per 1 m/s increase in c-f PWV and IRR 0.66 (95% CI: 0.49 to 0.89, p = 0.01) per % increase in Aix75. There was no association between arterial stiffness and P-wave indices, OR 1.09 (95% CI: 0.85 to 1.40), p = 0.50 for abnormal PWTFV1, and β −0.003 (−0.10 to 0.09), p = 0.95 for P-wave duration, both per 1 m/s increase in c-f PWV.

Conclusions

Arterial stiffness, measured as either c-f PWV or Aix75, was associated with fewer PACs, whereas no association was found with P-wave indices. The association between arterial stiffness and atrial myopathy is complex and merits further study.

期刊介绍： The ANNALS OF NONINVASIVE ELECTROCARDIOLOGY (A.N.E) is an online only journal that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. ANE is the first journal in an evolving subspecialty that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. The publication includes topics related to 12-lead, exercise and high-resolution electrocardiography, arrhythmias, ischemia, repolarization phenomena, heart rate variability, circadian rhythms, bioengineering technology, signal-averaged ECGs, T-wave alternans and automatic external defibrillation. ANE publishes peer-reviewed articles of interest to clinicians and researchers in the field of noninvasive electrocardiology. Original research, clinical studies, state-of-the-art reviews, case reports, technical notes, and letters to the editors will be published to meet future demands in this field.
