When excluding patients with hypertrophic cardiomyopathy (n = 15) and patients with storage disease (n = 3), predictors of outcome of the remaining 102 patients with DCM and 65 patients myocarditis in univariable analysis were presence of LGE (HR 1.8; 95% CI 1.0–3.3; p = 0.040), BNP>100 ng/l (HR 2.0; 95% CI 1.2–3.6; p = 0.013), TnI ≥0.03 μg/l (HR 3.0; 95% CI 1.7–5.3; p<0.0001), LVEF ≤40% (HR 5.4; 95% CI 2.8–10.6; p<0.0001), LVEDD >55 mm (HR 3.0; CI 1.7–5.2; p<0.0001) and QRS duration >98 ms (HR 2.0; 95% CI 1.1–3.5; p = 0.017). The gene discussed is NPPB; the disease is hypertrophic cardiomyopathy.
