Brief Summary:
Arterial hypertension (AH) is an important clinical social and economic problem, related to the increased cardiovascular risk. AH is associated with cardiovascular hemodynamic alterations, including left ventricular diastolic dysfunction (LVddf). In consequence of increased blood pressure, the effectiveness of LV as a blood pump decreases and the symptoms of heart failure (HF) may occur. Thus, the identification of noninvasive markers related with the progression from the asymptomatic AH to LVddf/HFpEF would be beneficial.
Another issue is that the diagnostic difficulties in patients with LVddf and HFpEF stem from the limited possibility to assess the hemodynamic response to exercise. Thus, there is a need for more detailed methods of cardiovascular monitoring while exercise testing.
We hypothesize that some new noninvasive hemodynamic parameters, characterizing left ventricular (LV) function and arterial stiffness, may help to predict the risk of cardiovascular events and future occurrence of LVddf/HFpEF. Moreover, we assume that cardiopulmonary exercise test (CPET), completed with new methods of noninvasive hemodynamic monitoring (impedance cardiography and applanation tonometry), would provide additional value in the assessment of the cardiovascular hemodynamic response to exercise.
The study is intended to verify these hypothesis.

Detailed Description:
Arterial hypertension (AH) is an important clinical social and economic problem, related to the increased cardiovascular risk.
AH is associated with cardiovascular hemodynamic alterations, including left ventricular diastolic dysfunction (LVddf). In consequence of increased blood pressure, the effectiveness of LV as a blood pump decreases and the symptoms of heart failure (HF), even with preserved ejection fraction (HFpEF), may occur. At the early stage, patients' complaints are not specific and difficult to clinical interpretation. As a consequence, these subjects frequently remain undiagnosed. Thus, the identification of noninvasive markers related with the progression from the asymptomatic AH to LVddf/HFpEF would be beneficial.
Another issue is that the diagnostic difficulties in patients with LVddf and HFpEF stem from the limited possibility to assess the hemodynamic response to exercise. Thus, there is a need for more detailed methods of cardiovascular monitoring while exercise testing.
The investigators hypothesize that some new noninvasive hemodynamic parameters, characterizing left ventricular (LV) function and arterial stiffness, may help to predict the risk of cardiovascular events and future occurrence of LVddf/HFpEF. Moreover, the investigators assume that cardiopulmonary exercise test (CPET), completed with new methods of noninvasive hemodynamic monitoring (impedance cardiography and applanation tonometry), would provide additional value in the assessment of the cardiovascular hemodynamic response to exercise.
Aims:
1. The identification of the new markers of cardiovascular risk in patients with arterial hypertension..
2. The identification of the new markers of progression from normal left ventricular diastolic function to left ventricular diastolic dysfunction.
3. The identification of the new noninvasive markers of progression to symptomatic heart failure.
4. The evaluation of the feasibility and usefulness of new methods of noninvasive hemodynamic monitoring (impedance cardiography and applanation tonometry) in the assessment of the cardiovascular hemodynamic response to exercise.
5. Multivariate assessment of cardiovascular response to the controlled exercise, taking into account left ventricular diastolic function and symptoms of heart failure.
6. The relation between laboratory markers of left ventricular remodeling with resting and exercise (noninvasive) hemodynamics.
The study will be performed in a prospective and observational design. No less than 120 hypertensive subjects will be enrolled.
After recruitment the following assessment will be performed:
* anamnesis and physical examination with anthropometrics (including body composition analysis with use of bioimpedance method);
* electrocardiogram;
* echocardiography (resting), including assessment of left ventricular systolic (2-D left ventricular ejection fraction, longitudinal strain) and diastolic function (including tissue Doppler imaging);
* impedance cardiography (resting);
* Applanation tonometry (resting);
* 24-h Holter-ekg (including heart rate variability analysis);
* 24-h ambulatory blood pressure monitoring;
* flow-mediated dilation of brachial artery (FMD);
* 6-minute walking test (6-MWT);
* Cardiopulmonary exercise test (CPET), supported by hemodynamic monitoring with impedance cardiography and applanation tonometry;
* Quality of life assessment (SF 36 questionnaire);
* Laboratory tests (including creatinine, urea, uric acid, lipids, glucose, microalbuminuria, N-terminal of the prohormone brain natriuretic peptide, galectin-3, copeptin, soluble ST2, Growth differentiation factor 15 (GDF-15), human tissue inhibitor of metalloproteinases 1 (TIMP-1), metalloproteinase 2 (MMP-2), metalloproteinase 9 (MMP-9), syndecan-1).
After 12 months (first control visit) and 24 months (second control visit) the echocardiography and clinical assessment (HF symptoms) will be performed to identify: 1/ patients with new onset LVDdf (among group N); 2/ patients with new onset HF (among group D)
Morover, the follow-up of min 48 months concerning cardiovascular events will be performed (as defined below)
