Abstract	A hipertensao arterial sistemica, em funcao de sua elevada prevalencia populacional, representa um fator de risco importante para o comprometimento cardiaco, provocando, principalmente, hipertrofia ventricular esquerda e associando-se a elevados indices de morbi-mortalidade entre os hipertensos. Sao discutidos aspectos diagnosticos da hipertrofia ventricular esquerda utilizando a Doppler-ecocardiografia, suas limitacoes tecnicas e implicacoes clinicas. A importância do padrao geometrico da hipertrofia do ventriculo esquerdo e seu significado clinico tambem sao analisados. A avaliacao da funcao diastolica do ventriculo esquerdo e revisada reforcando os conceitos fisiopatologicos e as 1imitacoes da investigacao nao-invasiva, assim como a importância da correlacao clinica e as dificuldades de sua interpretacao. Novas tecnicas como Doppler tecidual, modo M colorido e caracterizacao tecidual ultra-sonica sao consideradas como opcoes de investigacao nao-invasiva entre os hipertensos. Tambem e abordada a importância da Doppler-ecocardiografia para diagnosticar e quantificar lesoes valvares e principalmente doenca coronariana associada entre os pacientes hipertensos, considerando tambem o ecocardiograma sob estresse. Concluindo, sao apresentadas as indicacoes consensuais da Doppler-ecocardiografia na hipertensao arterial sistemica segundo as recomendacoes do American College of Cardiology e da American Heart Association.
