The overall goal of this study will be to assess and monitor the adherence to and
effectiveness of the new prescribing guidelines for cabergoline.
Specific objectives will be to assess: 1. The indication for use of cabergoline (Parkinson,
hyperprolactinemia, other) 2. Prior treatment strategies in patients who start cabergoline
treatment for Parkinson's Disease 3. The percentage of cabergoline users who are prescribed
doses above 3 mg per day 4. Whether cabergoline users are monitored by echocardiography
prior and during treatment. 5. The incidence and prevalence of valvular fibrosis

Primary | Incidence of Valvular Fibrosis | Incidence of valvular fibrosis was calculated as number of participants with documented valvulopathy during cabergoline treatment and absence of any valve damage at baseline divided by number of participants without any valve damage at baseline and at least 1 additional echocardiography examination during follow-up while on cabergoline treatment. Percentage of participants with valvular fibrosis are reported. | Baseline (Week 1) up to Week 339 | Yes |
Primary | Prevalence of Valvular Fibrosis | Prevalence of valvular fibrosis was calculated as number of participants with documented valvulopathy during cabergoline treatment divided by number of participants with at least 1 echocardiography examination.
