RESUMO
Objetivos:
O objetivo deste estudo foi avaliar a frequência de síndrome do intervalo QT longo (SQTL) no traçado eletrocardiográfico de pessoas idosas e o uso concomitante de fármacos que possam agravá-la.Métodos:
Trata-se de um estudo observacional, do tipo corte transversal, de pacientes idosos atendidos nos ambulatórios de especialidades do Hospital Santa Casa de Misericórdia de Vitória (ES), durante o período de seis meses.Resultados:
Participaram do estudo 163 pacientes com 75 ± 8 (6094) anos de idade, 60,7% (n = 99) dos quais eram do sexo feminino. Do total de pacientes, 33,1% (n = 54) faziam uso regular de pelo menos um fármaco de risco para prolongamento de intervalo QT corrigido (QTc). Trinta e quatro pacientes (20,9%) apresentaram QTc longo e 15 (9,2%), QTc de risco. Dos pacientes com QTc de risco, 4 (23,5%) faziam uso de pelo menos 1 fármaco de risco para prolongamento do intervalo QT (p = 0,07).Conclusão:
Nesta amostra, observou-se alta frequência de SQTL, bem como o uso de fármacos potencialmente causadores de SQTL e arritmias.ABSTRACT
Objectives:
The objective of this study was to evaluate the frequency of long QT syndrome (LQTS) in the electrocardiographic tracing of elderly people and the concomitant use of drugs that can aggravate this condition.Methods:
This is a crosssectional, observational study of elderly patients in outpatient services at Hospital Santa Casa de Misericórdia de Vitória, over a six-month period.Results:
A total of 163 patients with 75 ± 8 (6094) years of age, 60.7% (n = 99) of whom were female, participated in the study. Of the total number of patients, 33.1% (n = 54) were regularly taking at least one pharmaceutical that increased the risk of QTc prolongation; 34 patients (20.9%) had prolonged QTc and 15 (9,2%) had at-risk QTc. Of these patients with at-risk QTc, 4 (23.4%) were using at least 1 1 pharmaceutical that increases the risk of QT prolongation (p = 0.07).Conclusion:
In this sample, a high frequency of LQTS was observed, as well as the use of pharmaceuticals that potentially cause LQTS and arrhythmias.
