Pertinent History

  • Manny presented with exercise intolerance, weakness, and a moist cough.
  • Her referring veterinarian, based on a recent physical exam and chest and abdominal radiographs, diagnosed congestive heart failure.
  • She reportedly has had a heart murmur since the owner obtained her at four years of age.
  • Approximately 2.5 months ago she was treated by the referring DVM for coughing with 2 weeks of prednisone 20 mg BID. The coughing returned post-therapy and she was then treated with 2 weeks of prednisone 20 mg BID and Lasix 25 mg BID. The cough returned again upon completion of the prednisone therapy.
  • She remains on Lasix.
  • Referral radiographs show pulmonary edema, an enlarged cardiac silhouette, and hepatomegaly.
