Arrhythmias & electrophysiologyCohort study
Role of ideal cardiovascular health metrics in reducing risk of incident arrhythmias
- Prospective cohort study
- community-based
- 4 US communities
Authors' conclusion
Achieving ideal CVH metrics recommendations by AHA in midlife was associated with a lower risk of incident arrhythmias later in life.
Study context
- Population
- Atherosclerosis Risk in Communities (ARIC) cohort participants from four US communities, cardiovascular health (CVH) metrics scored at baseline (1987–89)
- Participants
- 13,078 participants
- Exposure
- Ideal vs intermediate vs poor CVH metrics
- Outcome
- Incident AF/flutter, ventricular arrhythmias and bradyarrhythmias (ICD-9 code)
Main finding
As reported in the abstract
Incident arrhythmias, ideal vs poor CVH metrics (adjusted)
Ideal vs PoorAdjusted hazard ratio (95% CI)
AF
0.59(0.50–0.69)
ventricular arrhythmias
0.38(0.28–0.51)
bradyarrhythmia
0.70(0.51–0.97)
- Atrial fibrillation/flutter (AF) events
- 2548
- Ventricular arrhythmia events
- 1363
- Bradyarrhythmia events
- 706
Observational data: associations, not effects.
Further findings
Adjusted population attributable fractions
- AF
- 29.9%
- Ventricular arrhythmias
- 54.4%
- Bradyarrhythmia
- 21.9%
Incident arrhythmias in people free of CHD over follow-up
- Association between CVH metrics and incident arrhythmias also seen
