Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Nurse Supervised Titration Clinic for beta blocker titration. Those randomised to the Nurse Supervised Titration Clinic will attend appointments as needed to achieve maximum tolerated dose of beta blocker as quickly as possible within a 6 month period. At each visit (taking approximately 1 hour) the nurse will assess the patient, determine appropriate medication changes and provide education. All changes to treatment will be approved by medical staff in the Heart Function Clinic. Recommendations for beta blocker up titration will be provided to the GP by HFC medical staff.
