Summary
This large-scale GWAS meta-analysis identified twelve variants at eleven loci associated with heart failure, with functional analysis implicating genes involved in cardiac development, protein homoeostasis, and cellular senescence. Mendelian randomisation analysis supported causal roles for atrial fibrillation, body mass index, and hypertension on heart failure risk, independent of coronary artery disease. The findings extend understanding of heart failure pathogenesis and suggest potential therapeutic targets.
UK applicability
The genetic findings are applicable to UK populations, though the study cohort composition should be examined for ethnic diversity. The identification of modifiable risk factors (BMI, hypertension) and their causal pathways may inform UK preventive cardiology and public health strategies.
Key measures
Genome-wide association study (GWAS) variants; odds ratios for heart failure association; Mendelian randomisation estimates for causal inference; functional annotation of implicated genes
Outcomes reported
The study identified twelve independent genetic variants at eleven genomic loci associated with heart failure through meta-analysis of 47,309 cases and 930,014 controls. Mendelian randomisation analysis assessed causal relationships between heart failure risk factors including coronary artery disease, atrial fibrillation, body mass index, and hypertension.
