Prevalence of frequent premature ventricular contractions and nonsustained ventricular tachycardia in older women screened for atrial fibrillation in the Women’s Health Initiative
Authors' conclusion
In postmenopausal women at high risk for AF, frequent PVCs were relatively common (4.3%) and correlated with higher CHARGE-AF score.
Study context
- Population
- Postmenopausal women without atrial fibrillation (AF) history but 5-year predicted AF risk ≥5% by CHARGE-AF score (Women's Health Initiative Strong and Healthy (WHISH) trial)866 at 6 mo, 777 at 12 mo
- Participants
- 1,067 women
- Outcome
- Prevalence of frequent PVCs and NSVT (>5 beats)
- Follow-up
- 7-day patches at baseline, 6 months and 12 months
Methodological detailssequential 7-day electrocardiogram (ECG) patch monitoring, participants of the WHISH trial
- Sequential 7-day ECG patch monitoring
- Participants of the WHISH trial
Main finding
As reported in the abstract
Frequent premature ventricular contractions (PVCs) on ≥1 patch
4.3%
≥1 nonsustained ventricular tachycardia (NSVT) episode
12
1.1%
Observational data: associations, not effects.
Further findings
Correlates of PVC frequency
- PVC frequency directly correlated with CHARGE-AF score and NSVT on any patch
- Detection of frequent PVCs increased with sequential monitoring
