- Registration Number
- NCT06035978
- Lead Sponsor
- University Hospital Ostrava
- Brief Summary
The aim of this study is to determine whether and how serum concentrations of the used medicinal products, including their metabolites, correlate with selected clinical indicators of heart failure (NT-proBNP concentration, 6-minute walk test, quality of life questionnaire, echocardiographic parameters, hospitalization for HFrEF, length of survival).
- Detailed Description
The prevalence of chronic heart failure increases with age, and this disease is one of the most common reasons for hospitalization in the elderly. In order to reduce the number of exacerbations, the frequency of hospitalizations, morbidity and mortality and improve the overall quality of life, the treatment strategy should be individually set for each patient, regularly monitored and reviewed.
Patients with chronic heart failure show significant differences in the pharmacokinetics of both cardiovascular and non-cardiovascular drugs. At the same time, they tend to be exposed to other prescribed medicinal products, and therefore there is an increased risk of drugs interactions. These findings emphasize the need for comprehensive pharmacokinetic studies in patients with chronic heart failure, together with the exploration of the potential benefit of biomarkers suitable for monitoring the clinical status of patients. Pharmacotherapy of chronic heart failure with reduced ejection fraction (Heart Failure with Reduced Ejection Fraction - HFrEF) currently consists of beta-blockers together with mineralocorticoid receptor antagonists, the combination of sacubitril/valsartan drugs and sodium-glucose transporter 2 inhibitors. Although the recommendation of therapeutic drug monitoring (TDM) in patients with chronic heart failure has not yet been established, its introduction can serve as an effective tool for detecting changes in the pharmacokinetics of drugs used, objectifying drug interactions and ascertaining patient adherence to treatment, thereby becoming part of safe personalized pharmacotherapy of this disease.
