Characteristics of the final result The study is to allow for identification of patients with hypertension, in whom an early introduction of pharmacological treatment of heart failure should be considered. Evaluation in the detection of asymptomatic myocardial dysfunction will include potential heart failure markers such as: cardiotrophin 1, cystatin C, serum syndecan-4, collagen III N-terminal propetide [PIIINP], MMP-2, MMP-7, MMP-8, MMP-9 and NT-proBNP, modern echocardiography methods and magnetic resonance imaging in order to increase the effectiveness of prevention, diagnosis and treatment optimalization.
