Patients with TG ≥150 mg/dL and a comparator cohort with TG 40 mg/dL were included. A sub-analysis was conducted in patients with TG 200–499 mg/dL. Hazard ratios (HR) were calculated from multivariate analyses controlled for patient characteristics and comorbidities using Cox proportional hazard modeling. New diagnosis of HF required diagnosis in the follow-up period without prior evidence of HF.Results: Multivariate analyses revealed a 19% higher rate of new HF diagnosis in the TG ≥150 mg/dL cohort (HR=1.192; 95% confidence interval [CI]=1.134–1.252; P
