Abstract
Objective: The aim of this study was to evaluate diastolic function of right and left ventricles in hypertensive patients and heart rate variability (HRV) according to the control of blood pressure. Design and method: We examine 103 hypertensive patients: group 1–41 newly diagnosed without treatment, group 2–31 with controlled hypertension and group 3–31 with resistant hypertension, uncontrolled in spite of treatment of more than 3 drugs. We assessed the traditional risk factors, echocardiography and HRV as well as blood pressure using ambulatory blood pressure monitoring. Differences between groups were analysed using one-way ANOVA and post-hoc Tukey test. Results: Table 1. Characteristics of patients:Conclusions: Patients with resistant or controlled hypertension did not differ in terms of both diastolic and systolic function of left ventricle or HRV indices in comparison to newly diagnosed. Whereas there were differences between groups (1 versus both 2 and 3) in some indices of right ventricular diastolic function (E/E’t, E’t) even after adjustment to age and blood pressure values.
