RESUMO

OBJETIVO:

Medir a espessura ventricular direita e esquerda em falecidos com história de hipertensão arterial, submetidos a necropsias clínicas.

MÉTODOS:

Foram selecionados 90 casos do Serviço de Verificação de Óbitos de Recife -PE, de ambos os sexos, com história de hipertensão arterial essencial, com relação à espessura das paredes cardíacas, além da correlação com outros achados de necropsia e informes clínicos.

RESULTADOS:

Observouse associação significativa entre a presença de hipertrofia ventricular esquerda (HVE) e direita (HVD), e de cardiopatia hipertensiva grave e HVD. Houve predomínio da HVD e HVE em homens, na faixa etária dos 60-79 anos, com maior prevalência nas etnias parda e negra, e naqueles com estado nutricional adequado ou com sobrepeso e em obesos.

CONCLUSÃO:

Observou-se que a presença de HVD relaciona-se com HVE, sugerindo que há fatores patogênicos semelhantes envolvidos no desenvolvimento da hipertrofia bilateral. A HVD parece associar-se à doença cardíaca mais grave, podendo, a partir de outros estudos, ser considerada novo fator prognóstico na avaliação dos pacientes hipertensos.
ABSTRACT

OBJECTIVE:

To measure the right and left ventricular thickness in deceased individuals with a history of hypertension submitted to clinical autopsies.

METHODS:

We selected 90 cases from the Death Verification Service of the city of Recife, state of Pernambuco, Brazil, of both sexes, with a history of essential arterial hypertension related to heart wall thickness, in addition to correlation with autopsy findings and other clinical reports.

RESULTS:

There was a significant association between the presence of left ventricular hypertrophy (LVH) and right ventricular hypertrophy (RVH) and between severe hypertensive cardiomyopathy and RVH. There was a predominance of RVH and LVH in men aged 60-79 years and a higher prevalence in the Brazilian mulatto and Black ethnic groups and in those with adequate nutritional status or overweight and obese individuals.

CONCLUSION:

It was observed that the presence of RVH was related to LVH, suggesting that there are similar pathogenic factors involved in the development of bilateral hypertrophy. The RVH seems to be associated with more severe heart disease and may, based on other studies, be considered as a new prognostic factor in the evaluation of hypertensive patients.
