Genome-wide association study reveals mechanisms underlying dilated cardiomyopathy and myocardial resilience
Why the study?
Dilated cardiomyopathy is an important cause of morbidity and mortality, but its causal mechanisms remain largely elusive.
What are the genetic loci and causal mechanisms underlying dilated cardiomyopathy?
Population
9,365 DCM cases and 946,368 controls
Comparison
DCM cases vs controls
Design
Large-scale genome-wide association study and multitrait analysis

Implication
May inform DCM prevention trials targeting weight and BP; hypothesis-generating from Level 4 genetics and requires prospective validation.
Structured PICO
What are the genetic loci and causal mechanisms underlying dilated cardiomyopathy?
P
Population
9,365 cases with dilated cardiomyopathy (DCM) and 946,368 controls
C
Comparator
946,368 controls
O
Outcome
Genome-wide significant loci associated with dilated cardiomyopathy
This large-scale GWAS identifies 70 genetic loci associated with DCM and highlights higher bodyweight and systolic blood pressure as actionable causal factors.
