Dobutamine stress CMR: can we predict outcome?
s m e p g m ( n f ( i t t f C c c s w m D w b t D p D D i ( 3 e s s n s p p r Dobutamine stress magnetic resonance (DSMR) is a well-established technique that is able to provide accurate detection of the contractile reserve in asynergic ischemic segments at low-dose dobutamine, and the assessment of reversible myocardial ischemia at high doses (1–3). The accuracy of the technique is due to the ...
متن کاملAdenosine stress perfusion CMR accurately identifies the culprit vessel
Background The diagnostic evaluation of patients with suspected ischaemic heart disease (IHD) frequently involves a functional assessment of ischaemia. Adenosine stress perfusion CMR is a non-invasive test with high sensitivity for the detection of IHD, however rarely is its accuracy for culprit vessel identification assessed. We sought to determine the accuracy of stress perfusion CMR for iden...
متن کاملElevation of high sensitive troponin T after CMR stress testing
Introduction High sensitive troponin T (hsTnT) is a highly specific marker of myocardial injury and one of the keystones in the diagnosis of acute coronary syndrome. Although hsTnT is thought to be released by myocardial cell damage, recent studies reported elevated levels after exercise testing and endurance sports. The exact mechanism of this phenomenon is discussed controversially. CMR stres...
متن کاملAdenosine stress CMR with spiral pulse sequences accurately detect CAD
Background Adenosine stress perfusion imaging with CMR has been limited by motion-induced dark-rim artifacts, which may be mistaken for true perfusion abnormalities. We have previously demonstrated that spiral pulse sequences can produce high quality first-pass perfusion images.[1] We have further improved this spiral technique using high-resolution variable density spiral trajectories and a no...
متن کاملRole of adenosine Stress CMR before Chronic Total Occlusion reopening
Methods 70 CTO patients without any other relevant coronary artery stenosis (or already treated if present at baseline angiography), underwent an adenosine stress CMR before a reopening attempt. ECG and echocardiographic (echo) data were available for all. Patients were considered suitable for the reopening procedure in case of myocardial ischemia and / or viable myocardium subtended to the CTO...
