Circulation, Volume 108 Suppl 1, 1 1 2003, Pages II39-42 Early versus delayed revascularization in patients with ischemic cardiomyopathy and substantial viability: impact on outcome. Bax JJ, Schinkel AF, Boersma E, Rizzello V, Elhendy A, Maat A, Roelandt JR, van der Wall EE, Poldermans D
Background: Patients with ischemic cardiomyopathy and viable myocardium may improve in function and prognosis following revascularization. Delayed revascularization may result in less favorable outcome, and therefore the impact of timing of revascularization on long-term outcome was evaluated. Methods and results: Patients (n=85) with ischemic cardiomyopathy and substantial viability (>or=25% of the left ventricle) on dobutamine stress echocardiography underwent surgical revascularization. Ba... Abstract

The American journal of cardiology, Volume 92, Issue 5, 1 1 2003, Pages 613-616 Effect of atorvastatin on myocardial contractile reserve assessed by tissue Doppler imaging in moderately hypercholesterolemic patients without heart disease. Bountioukos M, Rizzello V, Krenning BJ, Bax JJ, Kertai MD, Vourvouri EC, Schinkel AF, Biagini E, Boersma E, Roelandt JR, Poldermans D
An improvement in myocardial longitudinal systolic velocities, assessed by pulsed-wave tissue Doppler imaging during low-dose dobutamine infusion, was observed at 6-month follow-up after 6 months of treatment with atorvastatin. Our findings indicate a favorable effect of atorvastatin on contractile reserve, possibly through an enhancement of flow-dependent coronary dilatation during stress. Abstract

Schinkel AF, Bountioukos M, Poldermans D, Elhendy A, Valkema R, Vourvouri EC, Biagini E, Rizzello V, Kertai MD, Krenning B, Krenning EP, Roelandt JR, Bax JJ
The aim of this study was to evaluate the relation between QT dispersion and myocardial viability as assessed by single-photon emission computed tomography. The study population included 97 consecutive patients with severely impaired left ventricular function secondary to chronic coronary artery disease. Patients with a low QT dispersion had a substantial amount of viable myocardium, whereas patients with a high QT dispersion had predominantly nonviable scar tissue. Abstract

Background and aim of the study: Aortic valve disease is becoming one of the most important cardiac diseases in western society. Low-dose dobutamine stress echocardiography (DSE) is recommended in patients with low-gradient aortic stenosis (AS) and severe left ventricular (LV) dysfunction. DSE is also used in patients with AS and moderately reduced or normal LV function for diagnostic purposes. The study aim was to assess the safety of DSE in the setting of AS and various degrees of LV dysfuncti... Abstract

The American journal of cardiology, Volume 92, Issue 1, 1 1 2003, Pages 1-4 Preoperative comparison of different noninvasive strategies for predicting improvement in left ventricular function after coronary artery bypass grafting. Bax JJ, Maddahi J, Poldermans D, Elhendy A, Schinkel A, Boersma E, Valkema R, Krenning EP, Roelandt JR, van der Wall EE
Thallium-201 (Tl-201) imaging and dobutamine stress echocardiography (DSE) are the most frequently used tests in the clinical setting for assessing viability. However, Tl-201 has a suboptimal specificity and DSE a suboptimal sensitivity to predict functional improvement after revascularization. F18-fluorodeoxyglucose (FDG) imaging is considered highly accurate, but availability is limited. Sequential imaging of Tl-201 and DSE may improve accuracy for assessing viability and may be comparable to... Abstract

European journal of heart failure, Volume 5, Issue 3, 1 1 2003, Pages 315-317 Eligibility for biventricular pacing in patients with an implantable cardioverter defibrillator. Molhoek SG, Bax JJ, van Erven L, Steendijk P, van der Wall EE, Schalij MJ
Implantable cardioverter defibrillator (ICD)-therapy prevents sudden death in patients at high risk, but incidence of death due to heart failure remains unaltered. Recent data suggest that biventricular (BV) pacing is useful in patients with heart failure. It is unclear, how many patients with an ICD indication may have an indication for BV pacing. Therefore all patients who received an ICD were analyzed for eligibility of BV pacing using the following criteria: NYHA class III or IV, QRS duratio... Abstract

The American journal of cardiology, Volume 91, Issue 12, 1 1 2003, Pages 1406-1409 Individual prediction of functional recovery after coronary revascularization in patients with ischemic cardiomyopathy: the scar-to-biphasic model. Rizzello V, Schinkel AF, Bax JJ, Boersma E, Bountioukos M, Vourvouri EC, Krenning B, Agricola E, Roelandt JR, Poldermans D
Currently, the prediction of improvement of left ventricular (LV) ejection fraction (EF) after revascularization in patients with ischemic cardiomyopathy relies only on viable myocardium extent, whereas both the amount of viable and scar tissue may be important. A model was developed, based on the amount of viable and nonviable myocardium, to predict functional recovery. Viable and scarred myocardium was defined by dobutamine stress echocardiography (DSE) in 108 consecutive patients. LVEF before... Abstract

Unlabelled: During the noninvasive assessment of myocardial viability with (18)F-FDG metabolic imaging, adequate regulation of metabolic conditions is needed to ensure optimal image quality. The aim of this study was to compare the feasibility and image quality of cardiac (18)F-FDG SPECT imaging using acipimox in patients with diabetes and patients without diabetes. Methods: Seventy patients with ischemic cardiomyopathy underwent (18)F-FDG SPECT using acipimox for the assessment of myocardial vi... Abstract

Background: Patients with a normal stress technetium 99m sestamibi study were shown to have a favorable outcome at intermediate-term follow-up. However, long-term survival has not been studied. The aim of this study was to evaluate the incidence and predictors of mortality and cardiac events at long-term follow-up after a normal exercise stress sestamibi study. Methods and results We studied 218 patients (mean age, 53 +/- 10 years, 108 men) who had normal myocardial perfusion assessed by Tc-99m... Abstract

Circulation, Volume 107, Issue 14, 14 2 2003, Pages 1848-1851 Statins are associated with a reduced incidence of perioperative mortality in patients undergoing major noncardiac vascular surgery. Poldermans D, Bax JJ, Kertai MD, Krenning B, Westerhout CM, Schinkel AF, Thomson IR, Lansberg PJ, Fleisher LA, Klein J, van Urk H, Roelandt JR, Boersma E
Background: Patients undergoing major vascular surgery are at increased risk of perioperative mortality due to underlying coronary artery disease. Inhibitors of the 3-hydroxy-3-methylglutaryl coenzyme A (statins) may reduce perioperative mortality through the improvement of lipid profile, but also through the stabilization of coronary plaques on the vascular wall. Methods and results: To evaluate the association between statin use and perioperative mortality, we performed a case-controlled study... Abstract

Borger van der Burg AE, Bax JJ, Boersma E, Bootsma M, van Erven L, van der Wall EE, Schalij MJ
Survivors of cardiac arrest due to ventricular arrhythmias are at risk for recurrent events. The role of revascularization in secondary prevention for survivors of cardiac arrest has been addressed in various studies with conflicting results. A total of 142 survivors of cardiac arrest with coronary artery disease were evaluated according to a standardized protocol, including 2-dimensional echocardiography, myocardial perfusion scintigraphy, coronary angiography, and electrophysiologic testing.

Versteegh MI, Lamb HJ, Bax JJ, Curiel FB, van der Wall EE, de Roos A, Dion RA
Objectives: Whether resection of a left ventricular (LV) aneurysm leads to improved global LV function remains controversial. Echo-planar magnetic resonance imaging (MRI) is a sensitive tool to detect changes in LV function. Therefore, the purpose of the present study was to monitor changes in global LV function and anatomy following LV aneurysm resection using MRI. Methods: The present study includes 12 patients with an anterior LV aneurysm. Echo-planar MRI evaluation of LV function was perform... Abstract

Objective: The aim of this study was to assess the incremental value of dobutamine stress echocardiography (DSE) for the risk stratification of diabetic patients who are unable to perform an adequate exercise stress test. Exercise capacity is frequently impaired in patients with diabetes. The role of pharmacologic stress echocardiography in the risk stratification of diabetic patients has not been well defined.
