Incretin-based Drugs and the Risk of Heart Failure

• Status: Completed
• Trial end date: 2015-05-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to determine whether incretin-based drugs (used to treat type 2 diabetes) taken either alone or in combination with other anti-diabetic drugs are associated with an increased risk of heart failure (HF) compared to other combinations of oral hypoglycemic agents (OHA).

The investigators will carry out separate population based cohort studies using administrative health databases in six jurisdictions in Canada, the US and the UK. Cohorts will be defined by the initiation of a new anti-diabetic drug when incretin-based drugs entered the market, with follow-up until hospitalization for HF. Analyses will be done separately for groups of patients with and without prior HF. The results from the separate sites will be combined to provide an overall assessment of the risk of HF in users of incretin-based drugs and by class of incretin-based drugs.
