Usefulness of semi-quantification of ischemic myocardium after adenosine stress magnetic resonance
Background Adenosine stress MR shows high sensitivity and intermediate-to-high specificity; therefore, there is a number of false positive patients that is referred to useless coronary angiography studies after a positive adenosine stress MR. We sought to verify whether the (semi) quantification of the amount of ischemic myocardium can improve the management of patients after a positive adenosi...
متن کاملComparison of dobutamine stress magnetic resonance, adenosine stress magnetic resonance, and adenosine stress magnetic resonance perfusion.
BACKGROUND Dobutamine stress MR (DSMR) is highly accurate for the detection of inducible wall motion abnormalities (IWMAs). Adenosine has a more favorable safety profile and is well established for the assessment of myocardial perfusion. We evaluated the diagnostic value of IWMAs during dobutamine and adenosine stress MR and adenosine MR perfusion compared with invasive coronary angiography. ...
متن کامل[Minimum salvaged myocardium after rescue percutaneous coronary intervention: quantification by cardiac magnetic resonance].
INTRODUCTION AND OBJECTIVES When fibrinolysis fails in patients with ST elevation myocardial infarction, they are referred for a rescue percutaneous coronary intervention (PCI). However, there is still no evidence of how much myocardium potentially at risk we can actually salvage after rescue PCI. METHODS Fifty consecutive patients. Cardiac magnetic resonance was performed within 6 days. Myoc...
متن کاملSafety of adenosine stress magnetic resonance imaging using a mobile cardiac magnetic resonance system.
BACKGROUND Contrast-enhanced magnetic resonance imaging (ceMRI) allows for the detection of ischemic heart disease. Aim of this prospective study was to show feasibility, practicability and safety of adenosine stress ceMRI in routine outpatients with a mobile scanner. METHODS Consecutive patients were scanned in six different cardiac outpatient centers with a 1.5 T mobile ceMRI scanner. First...
متن کاملaccuracy of dobutamine stress echocardiography in detecting recovery of contractile reserve after revascularization of ischemic myocardium
background: this study was designed to investigate the accuracy of dobutamine stress echocardiography (dse) in detecting the post-revascularization recovery rate of contractile reserve (cr) in ischemic myocardium. methods: a total of 112 segments from seven patients with low ejection fraction (<35%) and coronary artery disease were evaluated with dse one week before and 12 weeks after coronary ...
