Background Therapy guided by N-terminal-pro-B-type natriuretic peptide (NT-proBNP) levels may improve outcomes in patients with chronic heart failure (HF), especially in younger patients with reduced left ventricular ejection fraction. It remains unclear whether treatment effects persist after discontinuation of the NT-proBNP-guided treatment strategy. Methods and Results Trial of Intensified versus standard Medical therapy in Elderly patients with Congestive Heart Failure randomized 499 patients with HF aged 60 years with left ventricular ejection fraction 45% to intensified, NT-proBNP-guided versus standard, symptom-guided therapy into prespecified age groups (60-74 and 75 years) during 18 months. A total of 329 patients (92%) alive at 18 months agreed to long-term follow-up. HF medication was intensified to a larger extent in the NT-proBNP-guided group. During long-term, NT-proBNP-guided therapy did not improve hospital-free (primary end point: hazard ratio, 0.87; 95% confidence interval, 0.71-1.06; P=0.16) or overall survival (hazard ratio, 0.85; 95% confidence interval, 0.64-1.13; P=0.25) but did improve HF hospitalization-free survival (hazard ratio, 0.70; 95% confidence interval, 0.55-0.90; P=0.005). Patients aged 60 to 74 years had benefit from NT-proBNP-guided therapy on the primary end point and HF hospitalization-free survival, whereas patients aged 75 years did not (P
