ABSTRACT

SUMMARY OBJECTIVES Acute pulmonary embolism (APE) is an important cause of cardiovascular mortality, due mainly to hemodynamic instability. In these cases, the recommendation is to perform some reperfusion procedure, with systemic thrombolysis being the main therapy used. However, national data evaluating the efficacy and safety of thrombolysis are scarce. METHODS Retrospective analysis of a case series. We included 13 patients diagnosed with high-risk APE and 4 patients with intermediate-high risk from a single-center, who were treated with alteplase 100mg. RESULTS The mean age of the patients was 55 years, most of them female (76.4%). Among the risk factors for VTE were immobilization (41.17%), contraceptive use (35.29%), cancer (17.63%), and previous history of DVT (11.76%). The most frequent clinical manifestations of APE were dyspnea (88.23%), hypoxia (82.35%), hypotension (82.35%), and tachycardia (64.70%). 82.35% of the patients had echocardiographic signs of right ventricular dysfunction, and 52.94% had increased troponin and BNP. Severe bleeding associated with thrombolysis occurred in 17.54% of cases. No patient died due to bleeding. There were 8 deaths from right ventricular failure (47%), 6 in the cases of patients presenting as high-risk APE (35.3%), and 2 in the cases of intermediate-high risk (11.8%). CONCLUSION Thrombolysis in patients with high-risk APE or intermediate-high risk had a severe bleeding rate of 17.6%. However, the high mortality of this population (47%) due to right ventricular failure justifies the use of this therapeutic modality.


RESUMO OBJETIVOS A embolia pulmonar aguda (EAP) é uma causa importante de mortalidade cardiovascular ao causar instabilidade hemodinâmica. Nesses casos, a recomendação é a realização de algum procedimento de reperfusão, sendo a trombólise sistêmica a principal terapia utilizada. No entanto, dados nacionais avaliando a eficácia e a segurança da trombólise são escassos. MÉTODO Análise retrospectiva de uma série de casos. Foram incluídos 13 pacientes com o diagnóstico de EAP de alto risco e quatro pacientes de risco intermediário-alto, de um único centro, e que foram tratados com alteplase 100 mg. RESULTADOS A média de idade dos pacientes foi 55 anos, sendo a maioria do gênero feminino (76,4%). Dos fatores de risco para TEV, estavam presentes a imobilização (41,17%), o uso de anticonceptivos (35,29%), câncer (17,63%) e história prévia de TVP (11,76%). As manifestações clínicas mais frequentes da EAP foram dispneia (88,23%), hipóxia (82,35%), hipotensão (82,35%) e taquicardia (64,70%); 82,35% dos pacientes apresentaram sinais ecocardiográficos de disfunção ventricular direita e 52,94% apresentaram aumento da troponina e BNP. Sangramento grave associado à trombólise ocorreu em 17,54% dos casos. Nenhum paciente faleceu em decorrência de sangramento. Houve oito mortes por insuficiência ventricular direita (47%): seis nos casos de paciente que se apresentaram como EAP de alto risco (35,3%) e duas nos casos de risco intermediário-alto (11,8%). CONCLUSÃO A trombólise nos pacientes com EAP de alto risco ou risco intermediário-alto apresentou uma taxa de sangramento grave de 17,6%. No entanto, a alta mortalidade dessa população (47%) por insuficiência ventricular direita justifica o uso desta modalidade terapêutica.
