In the current study, ST-segment elevation during DSE was rare, occurring in 3% of 4240 patients. All of these patients had abnormal DSE. We observed a high prevalence of multivessel and severe CAD in the patients who underwent coronary angiography. There was a high event rate (77%) during follow-up.
.
Conclusions: Patients with stress-induced ST-segment elevation during DSE commonly have severe CAD and are at high risk for events during follow-up. These patients should be considered for coronary angiography.

No eco de esforço, o ECG é feito com o software de ergometria ligado, sendo a análise do ECG feita de modo instantâneo.
Alguns alunos perguntam sobre o valor do método gráfico, aparentemente superado pela imagem.
O ECG sempre é útil, mesmo quando é normal. Um exame normal é marcador de bom prognóstico, mas no caso do Ecostress, o ECG alterado não deve mudar o laudo da imagem.
