The scope of this entire study is to examine the patients as follows::
Complete Echocardiographic Study including the index of left ventricular mass and relative wall thickness (RWT), measurement acquired from left parasternal longitudinal axis.
Further assessment will be diastolic function and filling pressures of the left ventricle using all indices of diastolic function that can be applied in patients with preserved ejection fraction according to the relevant guidelines of the European Society of Cardiology .
This will include the tissue velocities of the mitral annulus (lateral, septal and average) and the ratio of early diastolic transmitral speed to early diastolic mitral annulus velocity.
The flow of the right upper pulmonary vein , will be recorded during the reverse wave. The flow in pulmonary veins (average of 3 different measurements) will be recorded additionally. The transmitral A wave duration will also be measured, with the Pulsed Doppler sample volume placed at the level of the mitral annulus (average of 3 different measures). The time difference between the Ar-A (reverse pulmonary venous - transmitral flow A wave) will be calculated .
The percentage change of E/A ratio with Valsalva will only be calculated in those patients who perform a substantial Valsalva manoeuvre, as an absolute decrease of E wave at least 20 cm / s.
Left atrial volume index (LAVI) and right ventricular systolic pressure (RVSP) will also be estimated.
Besides left ventricular diastolic function and filling pressures, investigators will also estimate the diameter of the ascending aorta and aortic arch (absolute values and indexed for body surface area).
The study of the endothelial function will be done by the method of flow-mediated dilatation of the right brachial artery by estimating the FMD.
Intima-media thickness of common carotic arteries will also be performed.
Quality of life and level of emotional stress- depression will be assessed with the use of specific questionnaires (EQ-5D questionnaires, Short Form 36 health survey questionnaire (SF-36), Beck Depression Inventory (BDI)).
Patient compliance with antihypertensive treatment will be assessed with the following questionnaires : Brief Medication Questionnaire 1 (BDQ1), Morisky 8-item Medication Adherence Questionnaire.
Additional evaluations will assess co-morbidities in each patient, taking a detailed medical history during the initial diagnostic examination (obstructive sleep apnea , diabetes and glycosylated hemoglobin calculation HbA1 , renal impairment by calculating creatinine clearance , etc.)
After 'three months' follow-up investigators will evaluate the efficacy of therapy in the regulation of hypertension for all patients. Baseline evaluations will be repeated at three months
