Enhanced sensitivity of dobutamine stress echocardiography by observing wall motion abnormalities during the recovery phase after acute beta-blocker administration.
Karagiannis SE, Bax JJ, Elhendy A, Feringa HH, Cokkinos DV, van Domburg R, Simoons M, Poldermans D
Dobutamine stress echocardiography (DSE) has a modest sensitivity for detecting single-vessel coronary artery disease (CAD). This study assessed the additional diagnostic value of new or worsening wall motion abnormalities during recovery after acute administration of beta blockers. The study population consisted of 200 patients (mean 59 +/- 11 years of age, 144 men), who underwent DSE. Images were acquired at rest, low dose, peak dose, and during recovery. Patients received intravenous metoprol...

Imaging techniques in nuclear cardiology for the assessment of myocardial viability.
Slart RH, Bax JJ, van Veldhuisen DJ, van der Wall EE, Dierckx RA, Jager PL
The assessment of myocardial viability has become an important aspect of the diagnostic and prognostic work-up of patients with ischemic cardiomyopathy. Although revascularization may be considered in patients with sufficient viable myocardium, patients with predominantly scar tissue should be treated medically. Patients with left ventricular dysfunction who have viable myocardium are the patients at highest risk because of the potential for ischemia but at the same time benefit most from revasc...

Human mesenchymal stem cells ectopically expressing full-length dystrophin can complement Duchenne muscular dystrophy myotubes by cell fusion.
Gonçalves MA, de Vries AA, Holkers M, van de Watering MJ, van der Velde I, van Nierop GP, Valerio D, Knaän-Shanzer S
Duchenne muscular dystrophy (DMD) is the most prevalent inheritable muscle disease. It is caused by mutations in the approximately 2.5-megabase dystrophin (Dys) encoding gene. Therapeutic attempts at DMD have relied on injection of allogeneic Dys-positive myoblasts. The immune rejection of these cells and their limited availability have prompted the search for alternative therapies and sources of myogenic cells. Stem cell-based gene therapy aims to restore tissue function by the transplantation...

Dispersion of repolarization in cardiac resynchronization therapy.
van Huysduynen BH, Swenne CA, Bax JJ, Bleeker GB, Draisma HH, van Erven L, Molhoek SG, van de Vooren H, van der Wall EE, Schalij MJ
Background: Proarrhythmic effects of cardiac resynchronization therapy (CRT) as a result of increased transmural dispersion of repolarization (TDR) induced by left ventricular (LV) epicardial pacing in a subset of vulnerable patients have been reported. The possibility of identifying these patients by ECG repolarization indices has been suggested. Objectives: The purpose of this study was to test whether repolarization indices on the ECG can be used to measure dispersion of repolarization during...

[The availability of only one statin is inadequate].
Jukema JW
When looking at the history of the prescription of a new class of drugs e.g. the statin, it is clear that for optimal use with regard to efficacy, areas of indication and safety, the continuous development of new compounds within this class was very advantageous. Competition between compounds is essential for providing best patient care. Thus the availability of only one statin was and continues to be inadequate for this purpose.

Genetic factors appear to be important in the restenotic process after percutaneous coronary intervention (PCI), as well as in inflammation, a pivotal factor in restenosis. TNFalpha, a key regulator of inflammatory responses, may exert critical influence on the development of restenosis after PCI. The GENetic DEterminants of Restenosis (GENDER) project included 3104 patients who underwent a successful PCI. Systematic genotyping for six polymorphisms in the TNFalpha gene was performed. The role o...

[Percutaneous coronary intervention with stent placement versus bypass operation in symptomatic multiple-vessel disease; lessons from an observational study].
van der Hoeven BL, Schalij MJ, van der Wall EE
In a large observational study comparing percutaneous coronary intervention (PCI) using stent implantation with coronary-artery bypass grafting (CABG), 3-year survival was better after CABG than after PCI with stenting. This was particularly true in patients with triple-vessel disease, and for patients with two-vessel disease with involvement ofthe proximal left anterior descending artery (LAD). Potential explanations for this finding are that with CABG 'future' culprit lesions are byp...

Clinical versus echocardiographic parameters to assess response to cardiac resynchronization therapy.
Bleeker GB, Bax JJ, Fung JW, van der Wall EE, Zhang Q, Schalij MJ, Chan JY, Yu CM
Currently, a clear definition of response to cardiac resynchronization therapy (CRT) is still lacking, and clinical and echocardiographic end points are used. It is also unclear whether patients with clinical responses also improve in echocardiographic end points (and vice versa). To better understand and define response to CRT, the relation between improvement in clinical and echocardiographic parameters was evaluated in 144 patients.
