Effect of Tirzepatide on Cardiovascular and Metabolic Parameters in Obese Adult Patients With Congenital Heart Disease
Starting soon · Phase 4 · Has a placebo group
Conditions studied: Obesity & Overweight, Adult Congenital Heart Disease
In brief
Several drugs have been shown effective in the treatment of obesity, with concomitant favourable cardiovascular effects. Today, there are no studies on novel anti-obesity drugs in patients with adult congenital heart disease (ACHD). Therefore, the investigators aim to study the effects of the anti-obesity drug tirzepatide (Munjaro) on cardiovascular and metabolic factors in obese patients with ACHD. In a 24-week, randomized, open-label, placebo-controlled clinical trial the investigators will compare the effects of tirzepatide versus placebo in ACHD patients diagnosed with obesity. Patients will be randomized in a 1:1 ratio to either the intervention or placebo group. Participants will have monthly visits to monitor progress. At the beginning and end of the study, a full investigation protocol will be performed.
