    Abstract:
    Impaired baroreflex sensitivity (BRS) is a marker of autonomous dysfunction, which may play an important role in the long-term development of arterial hypertension, disease progression as well as complications related to global cardiovascular risk. The aim of the study was to evaluate the clinical significance of baroreflex sensitivity in hypertensives with/without major cardiovascular events. We found out that essential hypertension is associated with decreased BRS, and that grade of hypertension is inversely related to BRS values. Spontaneous BRS values in hypertensives with major cardiovascular event (stroke, myocardial infarction) were significantly lower even 6 months and more after myocardial infarction and stroke onset compared to remaining patients (p < 0.05). BRS is a clinically applicable, noninvasive method for assessing early dysfunction of autonomic nervous system, which seems to be an additive emerging marker of cardiovascular risk stratification in hypertensive patients.
