Objetivo
Avaliar as características estruturais, hemodinâmicas
e funcionais do coração em doentes com disfunção
diastólica e hipertensão arterial, com e sem
sintomatologia associada.
Materiais e Métodos
Estudo observacional prospetivo, de abordagem
quantitativa. Foram incluídos todos os sujeitos
com mais de 18 anos, com disfunção diastólica e
hipertensão arterial, no período entre 15 de julho e
31 de dezembro de 2017. Todos os sujeitos foram
submetidos à realização de um ecocardiograma, de
onde resultou o registo de parâmetros relacionados
com a avaliação estrutural, hemodinâmica e
funcional, tais como, a fração de ejeção do ventrículo
esquerdo, o volume da aurícula esquerda, o diâmetro
do ventrículo esquerdo, a relação E/e´, a pressão
sistólica da artéria pulmonar ou a velocidade do jato
de regurgitação tricúspide.
Resultados Principais
A amostra do estudo foi composta por 58 indivíduos,
de ambos os géneros, com idades entre os 35 e os 65
anos. Verificou-se existir relação do grau de disfunção
diastólica com o volume da aurícula esquerda e com
a pressão sistólica arterial pulmonar (p=0,001).
Todos indivíduos com grau II de disfunção diastólica
apresentam sinais e sintomas associados, sendo esta
relação estatisticamente significativa (p=0,001).
Apenas 19,15% dos indivíduos com grau I de
disfunção diastólica apresentaram sintomatologia.
A sintomatologia demonstrou ser sobreponível
com diversos parâmetros ecocardiográficos, tais
como, volume da aurícula esquerda, pressão sistólica
arterial pulmonar, relação E/e´, velocidade do jato de
regurgitação tricúspide (p=0,001).
Conclusão
A manifestação clínica dos doentes com disfunção
diastólica de grau II mostrou-se consideravelmente
mais prevalente do que nos doentes com disfunção
diastólica de grau I. Os parâmetros ecocardiográficos
avaliados estão significativamente relacionados com
a evolução da patologia, pelo que o diagnóstico
precoce se assume como fundamental.
ABSTRACT Objective To evaluate the structural, hemodynamic and functional characteristics of the heart in patients with diastolic dysfunction and arterial hypertension, with and without associated symptoms. Materials and Methods Prospective observational study with a quantitative approach. All subjects over 18 years old, with diastolic dysfunction and arterial hypertension, were included in the period between July 15 and December 31, 2017. All subjects underwent an echocardiogram, which resulted in the recording of related parameters with structural, hemodynamic and functional evaluation, such as left ventricular ejection fraction, left atrial volume, left ventricular diameter, E/e´ ratio, pulmonary artery systolic pressure or tricuspid regurgitation jet velocity. Main results The study sample consisted of 58 individuals, of both genders, aged between 35 and 65 years. There was a relationship between the degree of diastolic dysfunction and left atrial volume and pulmonary arterial systolic pressure (p=0.001). All individuals with grade II diastolic dysfunction have associated signs and symptoms, and this relationship is statistically significant (p=0.001). Only 19.15% of individuals with grade I diastolic dysfunction had symptoms. The symptoms showed to be overlapping with several echocardiographic parameters, such as left atrial volume, pulmonary arterial systolic pressure, E/e´ ratio, tricuspid regurgitation jet velocity (p=0.001). Conclusion The clinical manifestation of patients with diastolic dysfunction grade II was considerably more prevalent than in patients with diastolic dysfunction grade I. The echocardiographic parameters evaluated are significantly related to the evolution of the pathology, so early diagnosis is considered fundamental.
