    ABSTRACT: INTRODUCTION: Findings from genome-wide association studies (GWASs) have provided foundational knowledge of the genetic basis of disease, facilitating precision approaches for prevention and treatment. Current GWAS results are limited by underrepresentation of individuals from diverse populations, leading to concerns with generalizability regarding our knowledge of the relationships between genes, traits, and disease. The Department of Veterans Affairs (VA) Million Veteran Program (MVP), one of the largest US-based biobanks, addresses this need; 29% of MVP comprises individuals genetically similar to African (AFR), Admixed American (AMR), and East Asian (EAS) reference populations. With over 635,000 participants and more than 44.3M genotyped variants linked with detailed phenotyp

Lifestyle context

Concrete actions anchored to the cited research. We do not prescribe, we describe.

Exercise

  • regular aerobic exercise Moderate

    Regular aerobic exercise reduces atrial fibrillation incidence and symptom burden, particularly important for individuals with genetic predisposition

    Aim for 150+ minutes of moderate-intensity aerobic activity per week

Lifestyle

  • excessive alcohol consumption Moderate

    Alcohol is a known trigger and risk factor for atrial fibrillation, particularly in genetically susceptible individuals

    Limit to no more than 1 drink per day or avoid entirely

  • maintain healthy body weight Moderate

    Genetic variant shows tissue-specific effects on adiposity regulation; weight management is critical for atrial fibrillation risk reduction

    Target BMI 18.5-24.9 kg/m2, with emphasis on reducing visceral adiposity

Screening

  • baseline electrocardiogram and symptom monitoring Moderate

    Baseline cardiac assessment and symptom surveillance are appropriate for individuals with genetic atrial fibrillation predisposition

    Obtain baseline ECG if not recently done; report palpitations, syncope, or chest discomfort promptly

  • blood pressure monitoring and control Moderate

    Hypertension is a major modifiable risk factor for atrial fibrillation in genetically predisposed individuals

    Check blood pressure at least annually; target <130/80 mmHg with pharmacotherapy if needed
