简要总结

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.

详细描述

Introduction Obesity is a complex multifactorial disease with major impact on the cardiovascular system and subsequent adverse cardiovascular events.

Congenital heart disease (CHD) is the most common congenital disease. With the advancement of the treatment nowadays around 90% of patients with mild, 75% with moderate, and 40% with complex congenital heart disease reach the age of 60 years. With aging, acquired heart disease is becoming more prevalent and poses a growing concern in adults with CHD (ACHD). The ACHD patients are at an increased risk for atherosclerotic cardiovascular disease and its risk factors. In comparison to the general population, patients with ACHD have more severe risk factors for atherosclerosis, which frequently clinically presents at an earlier age and has increased morbidity and mortality.

Among well known risk factors for atherosclerotic cardiovascular disease, obesity plays an important role. It is estimated that, similarly to general population, up to 40-50% of ACHD patients are overweight or obese. These patients are at an increased risk for arterial hypertension, hyperlipidaemia, and diabetes. The development of obesity in ACHD is multifactorial, potentially including inadequate education on healthy lifestyle, sedentary lifestyle, and overfeeding during infancy.

CHD is a long-life disease, requiring frequent interventions throughout life, among them also surgical and catheter interventions. Obesity poses a risk for complications in surgical and catheter interventions, which increase morbidity and mortality in these patients.

Novel pharmacological treatment of obesity is an emerging help in reducing not only weight in obese patients but also contributing to diminishing obesity-related adverse effects.
