|Title:||Estrogen deprivation induces lipid profile impairment but not cardiac dysfunction in ovariohysterectomized dogs|
|Abstract:||Studies in human medicine have shown that in addition to affecting the reproductive system, the hormone estrogen also has cardioprotective effects. The present study hypothesized that ovariohysterectomized (OVH) dogs would have a higher incidence of cardiac dysfunction and impairment of lipid profiles compared to intact female dogs. Thirty healthy female dogs were divided into two groups, 15 intact female dogs and 15 OVH dogs. All the dogs underwent a physical examination, including investigation of physical parameters, blood collection for lipid profile measurement, thoracic radiography, electrocardiography and echocardiography. Physical examination parameters, electrocardiographic parameters, heart size and cardiac function in OVH dogs were not different when compared to intact female dogs. However, in the OVH dogs, triglyceride and very-low-density lipoprotein levels were increased, while high-density lipoprotein was significantly decreased compared to the intact female dogs (P<0.05). Differences between the groups in total cholesterol and low-density lipoprotein did not reach statistical significance. We concluded that estrogen deprivation in dogs can induce lipid profile impairment but not cardiac performance impairment 1 year after an ovariohysterectomy.|
