A 14-year-old male castrated domestic short-hair feline was diagnosed with suspected thromboembolism at the level of the brachial plexus causing pain and lameness, asymmetric concentric hypertrophy (unclassified cardiomyopathy) of the left ventricle, and a Grade IV/VI heart murmur. The cat responded well to a combination of conventional therapy and traditional Chinese veterinary medicine (TCVM). This Integrative Medicine approach consisted of anticoagulant pharmaceuticals combined with acupuncture, Tui-na in the clinic and home, Class IV laser, Chinese herbal medicine, and home rehabilitation exercises. Herbal medicine consisted of modified Yang Xin Tang (Heart Qi Tonic^TM) and modified Fu Fang Dan Shen Pian (Compound Dan Shen^TM). The integration of therapies both conventional and non-traditional allowed tapering of anticoagulant medications and improved quality of life for the cat. This case demonstrates the positive relationship obtained when integrating medical treatments and summarizes blending of Chinese herbal and pharmaceutical medications.
