Avaliação da circulação cerebral entre jovens saudáveis filhos de normotensos e filhos de hipertensos essenciais em um domínio de tempo

Abstract

7 ABSTRACT BACKGROUND: Hypertension consists of a disease of epidemiological relevance, with great influence of genetic order and systemic repercussion in noble organs. Thus, it becomes one of the most important current clinical challenges in the health area to understand its pathophysiology. OBJECTIVE: To evaluate healthy normotensive patients in search of early alterations possibly inherited from essential hypertensive parents, through heart rate variability techniques, in health academics at a University Hospital. METHOD: This is a cross-sectional, observational, descriptive study in a university hospital between March 2017 and August 2018. From healthy volunteers, 57 healthy volunteers were selected from 57 volunteers aged 18-30. two groups: 9 children of hypertensive parents and 12 children of normotensive parents. We performed analysis in the RMSSD domain through cerebral blood flow velocity waves captured by transcranial Doppler. Statistical analysis was performed through the SPSS14.0 program. Data were tested for normality using the Shapiro-Wilk technique. RESULTS: The values of systolic and diastolic blood pressure, mean cerebral artery flow velocity, systolic peak interval and time domain heart rate variability indexes (RMSSD and SD) did not present statistically significant differences between the groups. CONCLUSION: Our study was not able to demonstrate early findings related to the past of essential hypertension in the family. It is possible that the tools used in this study are not sufficient to detect early dysautonomic changes in this population with a low average age.
