Clinical trials for cats

  • CSRC Protocol # 004.17

    Status:  Currently enrolling


    Vitamin D has long been known to play an important role in regulating bone and calcium metabolism. However, vitamin D also is associated with other body systems and disease conditions. There is growing recognition of associations between vitamin D status and cardiovascular diseases in people, including hypertension and heart disease leading to heart failure.  Vitamin D has been shown to have several cardioprotective effects.  In people with cardiovascular disease, vitamin D deficiency is associated with disease progression and poor prognosis.

    Recently, two studies in dogs with heart failure have identified lower vitamin D concentrations compared to healthy controls, and it appears that this may be associated with worse outcomes . It is not known whether cats with heart disease have low levels of vitamin D compared to normal cats, and if so, whether an association exists between vitamin D status and disease severity . Cardiomyopathies are common heart diseases in cats, affecting 10-15% of all cats.

    Inclusion Criteria:

    Cats with dilated, hypertrophic, restrictive, or unclassified cardiomyopathies of any stage of severity and with no other major disease conditions

    Client benefits:

    The study covers the cost of 4 blood tests (packed cell volume, total solids, Azo-Stix, and glucose). Blood for these tests will be analyzed immediately so that information can be used to assist in the care of the individual cat. In addition, your cat's participation will allow us to gain information which will help in the diagnosis and treatment of other cats with heart disease. You understand that your cat's participation in this study may not alleviate or cure his/her condition.
