Design outcomes

Primary

MeasureTime frame
The aim of this study is to systematically and prospectively assess the metabolic and nutritional status of heart failure patients suffering from severe symptomatic aortic valve stenosis and severe symptomatic mitral valve regurgitation in correlation to the extent of heart failure symptoms. Heart failure patients will be characterized clinically, functionally, and metabolically before, and 6 month and 12 month after interventional valve therapy to quantify changes of these parameters due to interventional valve therapy. Our intention is to better understand the underlying pathophysiology of heart failure caused by severe aortic valve stenosis and severe mitral valve regurgitation, and their existing relationship to cardiac cachexia. To reach this aim we want to determine clinical, functional, metabolic parameters and biomarkers, especially focusing on the ability of patients to recover from heart failure symptomatology following treatment. Methods: clinical investigation (body mass index (BMI), waist circumference, skin fold measurement), echocardiography, specific laboratory measurements (NT-pro-BNP, insulin, ghrelin, adiponectin, leptin, peptides, TNF alpha, GLP-1, ANP, P3NP, cholecystokinin). Insulin resistance measured as HOMA-Index in the blood. These parameters are measured before intervention, and 6 month and 12 months after the intervention during the follow-up visit.

Secondary

MeasureTime frame
A further study aim is to measure energy metabolism and substrate utilization in heart failure patients suffering from severe aortic valve stenosis and severe mitral valve regurgitation, and before and after interventional valve therapy, and calculate their changes. Measurement method: Bioelectronic impedance analysis (BIA) and energy metabolism measurement by means of calorimetry. These parameters are measured before and 6 months after therapy (subgroup).
