ABSTRACT
OBJECTIVES:
In this extended follow-up study of the DANISH (Danish Study to Assess the Efficacy of Implantable Cardioverter Defibrillators in Patients with Non-ischemic Systolic Heart Failure on Mortality) trial, adding 4 years of additional follow-up, we examined the effect of implantable cardioverter-defibrillator (ICD) implantation according to baseline N-terminal pro-B-type natriuretic peptide (NT-proBNP) level.BACKGROUND:
In the DANISH trial, NT-proBNP level at baseline appeared to modify the response to ICD implantation.METHODS:
In the DANISH trial, 1,116 patients with nonischemic systolic HF were randomized to receive an ICD (N = 556) or usual clinical care (N = 550). Outcomes were analyzed according to NT-proBNP levels (below/above median) at baseline. The primary outcome was death from any cause.RESULTS:
All 1,116 patients in the DANISH trial had an available NT-proBNP measurement at baseline (median 1,177 pg/mL; range 200-22,918 pg/mL). There was a trend toward a reduction in all-cause death with ICD implantation, compared with usual clinical care, in patients with NT-proBNP levels lower than the median (HR 0.75 [95% CI 0.55-1.03]), but not in those with higher NT-proBNP levels (HR 0.95 [95% CI 0.74-1.21]) (Pinteraction = 0.28). Similarly, ICD implantation significantly reduced the rate of cardiovascular (CV) and sudden cardiovascular death (SCD) in patients with NT-proBNP levels lower than the median (CV death, HR 0.69 [95% CI 0.47-1.00]; SCD, HR 0.37 [95% CI 0.19-0.75]), but not in those with higher levels (CV death, HR 0.94 [95% CI 0.70-1.25]; SCD, HR 0.86 [95% CI 0.49-1.51]) (Pinteraction = 0.20 and 0.08 for CV death and SCD, respectively).CONCLUSIONS:
Lower baseline NT-proBNP levels could identify patients with nonischemic systolic HF who may derive benefit from ICD implantation.
