Myocardial perfusion imaging for evaluation and triage of patients with suspected acute cardiac ischemia: a randomized controlled trial

2015 ESC guidelines for the management of acute coronary syndromes in patients presenting without persistent ST-segment elevation

“…Podobnie wykazano, że obrazowanie perfuzji mięśnia sercowego techniką izotopową znajduje zastosowanie w stratyfikacji ryzyka u pacjentów z ostrym bólem w klatce piersiowej sugerującym ACS. Spoczynkowa scyntygrafia mięśnia sercowego, dzięki wykrywaniu trwałych ubytków perfuzji, sugerujących martwicę miokardium, może być przydatna w początkowej selekcji pacjentów przyjmowanych z powodu bólu w klatce piersiowej, bez zmian w EKG lub podwyższonego stężenia troponin sercowych [72]. Połączenie badania obciążeniowego i spoczynkowego może się przyczynić do dalszej poprawy oceny niedokrwienia, a prawidłowy wynik badania wiąże się z doskonałym rokowaniem [73,74].…”

Uso da cintilografia miocárdica em repouso durante dor torácica para descartar infarto agudo do miocárdio

“…Myocardial perfusion scintigraphy was introduced to the emergency room in order to speed up the evaluation of patients at low risk of having an acute coronary syndrome, especially those patients with normal or nondiagnostic ECGs 7 . Several observational studies have shown that scintigraphy has a high predictive value in this context to confirm the absence of myocardial infarction or subsequent cardiac events [7][8][9][10][11] . In a multicenter randomized study conducted in the United States, the addition of scintigraphy to the conventional approach to evaluating chest pain in the emergency room made it possible to determine earlier either the presence or absence of myocardial ischemia, thus facilitating early screening and reduction of time spent at chest pain observation units 12 .…”

“…For this reason it has been included as part of the protocol at our institution (Hospital Pró-Cardíaco) 8 .…”

Short- and long-term cardiac events in patients with chest pain with or without known existing coronary disease presenting normal electrocardiogram

“…Positive stress echocardiography was defined by the new detection or increasing onset of preexisting kinetics alterations or by the onset of angina and/ or ECG changes. Eventually, pharmacologic stress myocardial perfusion imaging (single photon emission computed tomography) was performed after drug washout [22,24]. Adenosine was given intravenous at the dose of 140 μg/min per kilogram for a period of 6 minutes, and radioactive tracer (25 MBq of technetium Tc 99m sestamibi myocardial perfusion tracer) was injected at the third minute.…”
