NT-proBNP in the Optimization of Treatment After Recent Acute Heart Failure Trial (BOT_AcuteHF)

This study has been completed.
Information provided by:
Università degli Studi di Brescia Identifier:
First received: July 9, 2007
Last updated: June 14, 2010
Last verified: July 2007
Hospitalizations for acute heart failure syndromes (AHFS) are associated with a high rehospitalisation and mortality rate. The aim of this study is to assess if the measurement of NT-proBNP levels before discharge may improve the prognosis of the patients recently admitted to hospital for AHFS

Condition Intervention Phase
Acute Heart Failure Procedure: Pre-discharge NT-ProBNP based treatment Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: NT-proBNP in the Optimization of Treatment After Recent Acute Heart Failure (BOT-AcuteHF) Trial

Primary Outcome Measures:
  • Incidence of unplanned cardiovascular hospitalization and cardiac deaths at 6 months in the control and the intervention groups. [ Time Frame: 30 months ]

Secondary Outcome Measures:
  • Cardiac mortality alone [ Time Frame: 30 months ]
  • Combined end-point of cardiac deaths, cardiovascular hospitalizations; no. of days in hospital during follow-up [ Time Frame: 30 months ]
  • Changes in LVEF, LV volumes, 6MWTD, NYHA class from discharge to 6 mts. f-up [ Time Frame: 30 months ]

Estimated Enrollment: 330
Study Start Date: July 2006
Study Completion Date: April 2010
Primary Completion Date: April 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: A
Pre-discharge NT-ProBNP based
Procedure: Pre-discharge NT-ProBNP based treatment

Discharge date, treatment and follow-up based also on the knowledge of NT-ProBNP levels measured at 2-3 days before discharge.

Discharge may be postponed and medical treatment may be changed when NT-ProBNP is >3000 pg/ml. Changes in medical treatment will include the following: increase in the diuretic dose, association of a different diuretic; combination of digoxin therapy; increase in the dose of the renin-angiotensin inhibitor; association of an ARB; association of a nitrate; short course of i.v. diuretic, vasodilator and/or inotropic therapy.

No Intervention: B
Discharge date and treatment not based on the knowledge of pre-discharge NT-proBNP levels
