Arrhythmias & electrophysiology
Role of ideal cardiovascular health metrics in reducing risk of incident arrhythmias
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)
Methodological detailscommunity-based, 4 US communities
- Community-based
- 4 US communities
