Introdução: É bem conhecida a precocidade do envolvimento cardíaco na hipertensão
arterial, nomeadamente o efeito desta patologia no ventrículo esquerdo. O ventrículo
direito, por outro lado, tem recebido menos atenção, apesar de se ter vindo a tornar claro
que o ventrículo esquerdo interage com o ventrículo direito e que a sua função é influenciada
pela performance do ventrículo esquerdo em doentes com hipertensão arterial.
Objetivo: Avaliar a influência da hipertensão arterial no ventrículo direito por parâmetros
ecocardiográficos.
Metodologia: Estudo do tipo retrospetivo, transversal e quantitativo. A amostra foi
constituída por 49 indivíduos de ambos os sexos com diagnóstico clínico de hipertensão
arterial, que realizaram ecocardiograma entre janeiro de 2017 e dezembro de 2019. Os
indivíduos foram agrupados de acordo com o grau de hipertensão arterial. Todos os dados
foram tratados no programa estatístico IBM SPSS® Statistics versão 25.0.
Resultados: Não foram encontrados doentes com disfunção sistólica do ventrículo direito
(TAPSE<17mm). As dimensões diastólicas do ventrículo direito foram encontradas
superiores nos indivíduos do grupo grau II de hipertensão (n=14,10mm/m2)
comparativamente aos indivíduos do grupo grau I (n=13,29mm/m2). Foi observada uma
correlação estatística positiva moderada entre a dimensão diastólica do ventrículo direito e
a dimensão diastólica do ventrículo esquerdo (rs=0,360; p=0,032).
Conclusão: A existente correlação entre as dimensões dos ventrículos direito e esquerdo
demonstra a importância e a necessidade em incluir uma avaliação mais precisa e completa
do ventrículo direito em doentes com hipertensão arterial, especialmente da sua função
diastólica.
Introduction: The early involvement of the heart in arterial hypertension is well known, specially the effect on the left ventricle. The right ventricle, on the other hand, has received less attention, although it has become clear that the left ventricle interacts with the right ventricle and that its function is influenced by the left ventricle performance in patients with hypertension. Objective: To study the influence of arterial hypertension on the right ventricle by echocardiography. Methodology: Retrospective, cross-sectional and quantitative study. The sample consisted of 49 individuals of both genders with clinical diagnosis of arterial hypertension, who had an echocardiography between January 2017 and December 2019. The individuals were grouped according to the degree of hypertension. All data were analysed using IBM SPSS® Statistics version 25.0. Results: No patients with right ventricle systolic dysfunction (TAPSE<17mm) were found. The diastolic dimensions of the right ventricle were found to be higher in group II of hypertension (n= 4,10mm/m2) compared to group I (n=13,29mm/m2). A moderate positive statistical correlation was observed between diastolic dimensions of the right ventricle and left ventricle diastolic dimension (rs=0,360; p=0,032). Conclusion: The existing correlation between the dimensions of the right and left ventricle demonstrates the importance and the need to include a more accurate and complete assessment of the right ventricle in patients with hypertension, especially its diastolic function.
