Assessment of myocardial viability by MRI

Collagen-Based Structures Containing the Peptoid Residue N-Isobutylglycine (Nleu): Conformational Analysis of Gly-Nleu-Pro Sequences by 1H-NMR and Molecular Modeling

“…All NMR experiments were carried out on an AMX-500 Bruker spectrometer using the same data acquisition and processing scheme (Redfield & Kuntz, 1975;Aue et al, 1976;Jeener et al, 1979;Kumar et al, 1980;Bax & Freeman, 1981;Braunsweiler & Ernst, 1983;Marion & Wuthrich, 1983;Shaka & Freeman, 1983;Bothner-By et al, 1984;Rance et al, 1984;Wider et al, 1984;Bax & Davis, 1985;Otting et al, 1986) previously used for the study of triple helices composed of (Gly-Pro-Hyp) n and of (Gly-Pro-Nleu) n sequences (Melacini et al, 1996a,b). For the hydrogen-exchange measurements, one-dimensional spectra were collected at 5°C over a period of 1 month.…”

CMR Imaging Assessing Viability in Patients With Chronic Ventricular Dysfunction Due to Coronary Artery Disease

“…To date, there have been 3 reviews regarding CMR and myocardial viability in which pooled data from previous original investigators were displayed (17)(18)(19). More recently, Schinkel et al (20) updated the work done by Bax et al (8,9) and also included CMR as a new technique in their analyses.…”

Thallium?201 SPECT and Low?Dose Dobutamine Stress Cine MRI for Predicting Functional Recovery of Regional Myocardial Contraction in Patients with Myocardial Infarction

“…Similar to low-dose dobutamine echocardiography, cine MRI during infusion of low-dose dobutamine can be used to evaluate myocardial contractile reserve in patients with myocardial infarction (Bax et al, 1999). Bear et al evaluated the diagnostic performance of dobutamine stress cine MRI in patients with chronic infarction by using FDG-PET as a gold standard.…”

“…Previous studies have shown that late recovery of regional left ventricular (LV) dysfunction can be expected in substantial percentage of patients after recent myocardial infarction (Bax et al, 1999;Beller, 1997). This finding indicates the importance of noninvasive detection of myocardial viability in managing patients after myocardial infarction.…”

“…Positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) has become a gold standard for assessing viable myocardium (Burt et al, 1995). The use of low-dose dobutamine for identification of myocardial contractile reserve is another noninvasive approach for determining viability (Bax et al, 1999;Beller, 1997). Tl-201 SPECT has been widely used for evaluating myocardial viability in patients with acute myocardial infarction and chronic coronary artery disease (Alfieri et al, 1993;Charny et al, 1994;Marzullo et al, 1993;Pace et al, 1998a;Perrone-Filardi et al, 1996;Ragosta et al, 1993;Senior et al, 1998).…”
