Clinical Efficacy of Pimobendan on Dogs with Chronic Mitral Valvular Diseases

초록

Pimobendan is a recently developed cardiac drug which is useful to control moderate to severe congestive heart failure (CHF) from chronic mitral valvular diseases (CMVI). Because of controversy related to the efficacy and safety of pimobendan in dogs, the optimal efficacy and safety of pimobendan was assessed in 20 dogs with CMVI in this study. Scores for quality of life, respiratory failure, circulatory failure and heart failure were evaluated along with radiographical and echocardiographical assessments for about 2 months period after the addition of pimobendan into the regular cardiac medications. This study proved clear evidence that pimobendan had beneficial therapeutic effects in dogs with advanced CMVI, without particular adverse effects. However, further studies are warranted to address the drug interaction with other cardiac therapeutics and to assess therapeutic effects in CHF from other type of heart diseases in dogs and other animals.
