Key result
The A allele of rs3766871 in RYR2 was associated with an increased risk of ventricular arrhythmias (OR 1.66; 95% CI 1.21-2.26; P=0.002) and sudden cardiac death in chronic heart failure.
Why the study?
Do common RyR2 variants associate with ventricular arrhythmias and sudden cardiac death in patients with chronic heart failure?
Case-Control
Do common RyR2 variants associate with ventricular arrhythmias and sudden cardiac death in patients with chronic heart failure?
Odds Ratio: 1.66 (95% CI 1.21–2.26)
p-value: p=0.002
Specific common variants in the RYR2 gene can independently predict both increased risk and protection against sudden cardiac death and ventricular arrhythmias in patients with chronic heart failure.

RYR2 variants may aid SCD risk stratification in chronic HF; hypothesis-generating and requires prospective validation before clinical use.
Ran et al. (2010) conducted a case-control in chronic heart failure. A allele of rs3766871 in RYR2 vs. Non-carriers was evaluated on ventricular arrhythmias (OR 1.66, 95% CI 1.21-2.26, p=0.002). The A allele of rs3766871 in RYR2 was associated with an increased risk of ventricular arrhythmias (OR 1.66; 95% CI 1.21-2.26; P=0.002) and sudden cardiac death in chronic heart failure.
