Combination Therapy With Beta Blocker and Inotrope in Decompensated Heart Failure: A Clinical Observation
Keywords:
decompensated heart failure (DHF), BB therapy, beta blocker (BB)Abstract
Inotropic support is contemplated in the presence of ongoing end-organ hypoperfusion or
refractory symptoms in decompensated heart failure (DHF). However, inotropic agents may
cause tachycardia leading to increased myocardial oxygen demand and arrhythmogenesis.1
Introduction of beta blocker (BB) therapy in DHF patients requiring inotrope support is
discouraged due to the negative hemodynamic impact of acute BB therapy.2-5 On the other
hand, reduction in heart rate by BB therapy results in decreased myocardial oxygen demand
and increased ventricular diastolic filling.6,7 Additionally, early introduction of BB therapy
improves outcome in heart failure.2-5,8
