Cirrhotic Cardiomyopathy: Another Case of a Successful Approach to Treatment of Hepatorenal Syndrome.

Hepatorenal syndrome (HRS) is defined as a failure of renal function, potentially reversible, in patients with liver cirrhosis and ascites. Recently, a component of cardiomyopathy associated with HRS was described, but the use of positive inotropic medicine as part of the treatment of the acute phase has not been extensively evaluated. We report a second case in our hospital of a patient with HRS type I without previous heart disease, with secondary hemodynamic decompensation due to liver disease, in which the abnormalities in systolic function by speckle-tracking echocardiography were observed and could be reversed by the use of inotropes. After partial response to current therapies, the patient presented a clinical and laboratorial response with improvement of renal function after infusion of dobutamine. Clinical studies are needed for the therapy approach to HRS taking into account myocardial dysfunction as a major contributing factor for renal dysfunction.

Cardiomiopatia cirrótica / Cirrhotic cardiomyopathy

A cardiomiopatia cirrótica (CMC) é uma disfunção cardíaca crônica que acomete pacientes cirróticos sem doença cardíaca prévia. Trata-se de uma doença inicialmente assintomática que se manifesta em situações de maior demanda metabólica, devido a menor capacidade cardíaca em aumentar seu inotropismo. O diagnóstico é pautado em alterações eletrocardiográficas e ecocardiográficas. Ainda não há tratamento específico para a CMC, sendo instituídas medicações sintomáticas semelhantes ao tratamento da insuficiência cardíaca. Esta revisão tem por objetivo descrever os aspectos fisiopatológicos, clínicos e diagnósticos da CMC, evidenciando as características clínicas, laboratoriais e eletro e ecocardiográficas no rastreio da disfunção cardíaca nos pacientes cirróticos.

Cirrhotic cardiomyopathy (CCM) is a chronic cardiac dysfunction that affects cirrhotic patients without history of heart disease. It is an initially asymptomatic disease that appears in situations of increased metabolic demand due to lower cardiac capacity to increase inotropism. Diagnosis is based on disorders revealed by electrocardiography and echocardiography. There is no specific treatmentfor CCM. Similar symptomatic medications are established to treat heart failure. This review aims to describe the pathophysiological, clinical and diagnostic aspects of CCM, showing the clinical, laboratory, electrocardiographic and echocardiographic characteristics in assessing cardiac dysfunction in cirrhotic patients.
