The purpose of this study is to determine whether Salbutamol is effective in the treatment of severe heart failure due to ischemic and non- ischemic cardiomyopathy.

Primary Outcome Measures:
  • Changes in plasma level of N-terminal pro-BNP at twelve weeks relative to baseline pro-BNP. [ Time Frame: 12 weeks from baseline pro-BNP assessment ]

Secondary Outcome Measures:
  • Adverse cardiovascular event: Death, ICD discharge, significant ventricular arrhythmias and hospitalization due to heart failure exacerbation [ Time Frame: 12 weeks after baseline assessment ]
    Record events of death, ICD discharge and hospitalization due to heart failure exacerbation. Interrogate ICD memory for significant ventricular arrhythmias (ventricular tachycardia and ventricular fibrillation) that did not cause ICD discharge.

  • NYHA class changes [ Time Frame: 12 weeks after baseline assessment ]
    We will assess NYHA functional class at baseline and after 12 weeks from the beginning of study medication.

  • Echocardiography parameters changes [ Time Frame: 12 weeks after baseline assessment ]

  • Minnesota Living with Heart Failure Questionnaire changes [ Time Frame: 12 weeks after baseline assessment ]
    repeat Minnesota Living with Heart Failure Questionnaire assessment

  • Non-ventricular arrhythmias and electrolytes disturbances [ Time Frame: baseline, 1 week, 4 weeks, 8 weeks and 12 weeks ]
    Plain ECG will be performed at the specified time intervals to detect asymptomatic non-ventricular arrhythmias (atrial fibrillation, atrial flutter, atrial premature beats, etc.) The venous blood will be drawn at the specified time intervals to follow closely after potassium levels (for timely detection of salbutamol induced hypokalemia and to correct accordingly), as well to monitor sodium levels as a prognostic and clinical marker of heart failure exacerbation

Estimated Enrollment: 30
Study Start Date: October 2011
Estimated Study Completion Date: March 2012
Estimated Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Salbutamol
The patients in the study groups will receive the selective β2 agonist, Salbutamol, in addition to their ongoing optimal heart failure therapy.
Drug: Salbutamol
The initial dose will be 0.5mg bid, with acceleration of the dose every two weeks by 1mg, up to a maximal dose of 2mg bid or an increase in heart rate by 50% above the baseline heart rate, as long as it remains <100 bpm
No Intervention: control
The patients in the control group will continue with their regular optimal medical therapy without any intervention.

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Ambulatory Patients with a diagnosis of ischemic and non-ischemic cardiomyopathy with a measured EF <35%, class III as defined by the NYHA with ICD and who receive optimal pharmacological therapy.

Exclusion Criteria:

  • atrial fibrillation
  • any significant valvular disease
  • chronic obstructive pulmonary disease who treated with inhaled β2 agonist
