Significance of Common Genetic Variants Associated with Non-Ischaemic Cardiomyopathy in the General Population

Eur J Heart FailPublished

  • Prospective cohort study
  • population-based
  • matched cohort (3:1) for non-ischaemic cardiomyopathy (NICM) development

Authors' conclusion

The NICM-GR correlates with LV function and dimension, and subsequent development of NICM in the general population.

Study context

Population
Unselected Olmsted County residents aged >45 years46 developed NICM
Participants
1,897 participants
Exposure
NICM genetic risk vs left ventricular (LV) function, dimensions and incident NICM
Outcome
Significance of common NICM-associated genetic variants (NICM-GR) in a general population
Follow-up
Median 16 years (IQR 15-17)

Main finding

As reported in the abstract

NICM-GR vs LVEF, linear regression beta [SE]

−2.68 [0.68], p < 0.001

NICM-GR vs LV end-systolic diameter, beta [SE]

0.22 [0.06], p < 0.001

NICM-GR vs LV end-diastolic diameter, beta [SE]

0.14 [0.06], p = 0.01

NICM-GR and NICM development, OR

2.27 (1.06-4.85), p = 0.03 (95% CI)

Observational data: associations, not effects.

Further findings

HF biomarkers (aldosterone, natriuretic peptides, ST2, galectin-3)

No significant association with NICM-GR

Age, sex and CV risk factors across NICM-GR quartiles

No significant differences between quartiles
