Complications associated with the use of temporary pacemaker in patients waiting for definitive device implantation.

OBJECTIVE: To determine the rate of complications associated with the use of temporary pacemakers in patients in the waiting list for the definitive pacemaker implantation in a public hospital located in São Paulo, SP, Brazil. METHODS: Retrospective observational study based on data extracted from medical records of patients admitted to Hospital Municipal Dr. Moyses Deutsch, Hospital Israelita Albert Einstein from January 2014 to December 2018. Patients aged 18 years or older, diagnosed with high degree atrioventricular block upon admission and with indications for definitive pacemaker implantation were included. All-cause mortality, clinical and surgical complications and length of hospital stay while waiting for the procedure were defined as primary outcomes. RESULTS: The sample comprised 66 patient allocated to one of two groups: with and without the need of temporary pacemaker while in hospital (n=45 and n=21, respectively). The rate of complications was higher in patients who used a temporary pacemaker (p<0.001). These included primarily pneumonia (p=0.048) and length of hospital stay (p=0.029). CONCLUSION: Patients who required a temporary pacemaker stayed longer in hospital. Longer hospital stay is associated with higher rates of general complications and all-cause mortality.

Supradesnivelamento do Segmento ST localizado como apresentação atípica de perimiocardite aguda / Located ST-Segment Elevation as atypical presentation of acute perimiocarditis

Relatamos o caso de um paciente jovem admitido no pronto-socorro com quadro de dor precordial. O eletrocardiograma de admissão identificou supradesnivelamento do segmento ST localizado em parede lateral associado à imagem em "espelho", com enzimas cardíacas altamente elevadas, o que sugere diagnóstico de síndrome coronariana com supradesnivelamento de ST. O ecocardiograma evidenciou derrame pericárdico com fração de ejeção preservada e ausência de alterações segmentares, sugerindo, assim, pericardite aguda, com comprometimento do miocárdio. Desta forma, foi realizada ressonância magnética cardíaca, que evidenciou presença de realce tardio não isquêmico, confirmando o diagnóstico de perimiocardite. Trata-se de situação pouco frequente na prática clínica e que merece maior compreensão e atenção por parte dos médicos que trabalham em prontos-socorros
