Body Composition Changes, Cachexia Impact on Bisoprolol and Ramipril Pharmacokinetics in Chronic Heart Failure Patients
This observational study aims to determine how body composition changes and cachexia impact the pharmacokinetics of bisoprolol and ramipril in patients with chronic heart failure, by measuring clearance, volume of distribution, area under concentration-time curve, maximal concentration, and time to maximal concentration.

Cohort
Tracking disease incidence in order to identify risk factors and understand disease progression over time.Summary
Study start date: October 1, 2011
Actual date on which the first participant was enrolled.Patients with chronic heart failure on treatment with bisoprolol and/or ramipril will be included. Study will consist of two study visits: baseline visit (V1) and visit which will be performed at least 6 months after baseline (V2). At both visits same procedures will be performed. On the day of the visit, patients will be asked to take their morning dose of bisoprolol and/or ramipril after the withdrawal of the first morning plasma sample. Additional 3 to 5 plasma samples will be taken within 5 hours post bisoprolol and/or ramipril dose in order to determine pharmacokinetic profile of both drugs. Body composition will be measured by bioimpedance and dual-energy X-ray absorptiometry. Renal function will be measured by clearance of intravenously administered iohexol. Biochemical parameters, muscle strength, fatigue and anorexia will be assessed in order to determine presence of cachexia. Changes in body composition will be correlated with changes in pharmacokinetic parameters of bisoprolol and ramipril. Pharmacokinetic parameters in cachectic patients will be compared to pharmacokinetic parameters in non-cachectic patients. Parameters of body composition will be correlated with the difference between measured and estimated renal function.
