Journal of the American College of Cardiology, Volume 44, Issue 1, 1 1 2004, Pages 1-9 Echocardiographic evaluation of cardiac resynchronization therapy: ready for routine clinical use? A critical appraisal. Bax JJ, Ansalone G, Breithardt OA, Derumeaux G, Leclercq C, Schalij MJ, Sogaard P, St John Sutton M, Nihoyannopoulos P
Cardiac resynchronization therapy (CRT) has been proposed as an alternative treatment in patients with severe, drug-refractory heart failure. The clinical results are promising, and improvement in symptoms, exercise capacity, and systolic left ventricular (LV) function have been demonstrated after CRT, accompanied by a reduction in hospitalization and a superior survival as compared with optimized medical therapy alone. However, 20% to 30% of patients do not respond to CRT. Currently, patients a... Abstract

Thrombosis and haemostasis, Volume 92, Issue 1, 1 1 2004, Pages 61-66 The risk of bleeding complications in patients with cytochrome P450 CYP2C9*2 or CYP2C9*3 alleles on acenocoumarol or phenprocoumon. Visser LE, van Schaik RH, van Vliet M, Trienekens PH, De Smet PA, Vulto AG, Hofman A, van Duijn CM, Stricker BH
The principal enzyme involved in coumarin metabolism is CYP2C9. Allelic variants of CYP2C9, CYP2C9*2 and CYP2C9*3, code for enzymes with reduced activity. Despite increasing evidence that patients with these genetic variants require lower maintenance doses of anticoagulant therapy, there is lack of agreement among studies on the risk of bleeding and CYP2C9 polymorphisms. It was, therefore, our objective to study the effect of the CYP2C9 polymorphisms on bleeding complications during initiation a... Abstract

European urology, Volume 46, Issue 1, 1 1 2004, Pages 65-71; discussion 71-2 Preliminary European results of local microwave hyperthermia and chemotherapy treatment in intermediate or high risk superficial transitional cell carcinoma of the bladder. van der Heijden AG, Kiemeney LA, Gofrit ON, Nativ O, Sidi A, Leib Z, Colombo R, Naspro R, Pavone M, Baniel J, Hasner F, Witjes JA
Introduction: Superficial bladder cancer can be treated by transurethral resection (TUR) and adjuvant intravesical therapy. Intravesical bacillus Calmette-Guérin (BCG) has been proven to be more efficacious with respect to recurrence prevention than intravesical chemotherapy, although at the cost of more severe side effects. There is a need for a new treatment modality with higher efficacy and less toxicity. The subject of this study is the efficacy of local microwave hyperthermia and chemothera... Abstract

European journal of pharmacology, Volume 493, Issue 1-3, 1 1 2004, Pages 161-165 Angiotensin deficiency in mice leads to dilated cardiomyopathy. Walther T, Steendijk P, Westermann D, Hohmann C, Schulze K, Heringer-Walther S, Schultheiss HP, Tschöpe C
To explore the role of angiotensin II, we assessed hemodynamics and cardiac function in angiotensinogen-deficient mice in comparison to wild-type animals. Left ventricular end-diastolic diameter and wall thickness were evaluated by echocardiography and systolic and diastolic left ventricular function by pressure-volume relations using a micro-conductance catheter. Compared to wild-type animals, the angiotensinogen-deficient mice were hypotensive and showed impaired systolic function. The hearts... Abstract

The American journal of cardiology, Volume 93, Issue 12, 1 1 2004, Pages 1461-1464 Head-to-head comparison between contrast-enhanced magnetic resonance imaging and dobutamine magnetic resonance imaging in men with ischemic cardiomyopathy. Kaandorp TA, Bax JJ, Schuijf JD, Viergever EP, van Der Wall EE, de Roos A, Lamb HJ
Contrast-enhanced magnetic resonance imaging (MRI) can predict functional recovery after revascularization. Segments with small, subendocardial scars have a large likelihood of recovery, and segments with transmural infarction have a small likelihood of recovery. Segments with an intermediate extent of infarction have an intermediate likelihood of recovery, and therefore, additional information is needed. Accordingly, the transmurality of infarction on contrast-enhanced MRI was compared with low... Abstract

The Journal of the Acoustical Society of America, Volume 115, Issue 6, 1 1 2004, Pages 3124-3141 Contrasting monaural and interaural spectral cues for human sound localization. Jin C, Corderoy A, Carlile S, van Schaik A
A human psychoacoustical experiment is described that investigates the role of the monaural and interaural spectral cues in human sound localization. In particular, it focuses on the relative contribution of the monaural versus the interaural spectral cues towards resolving directions within a cone of confusion (i.e., directions with similar interaural time and level difference cues) in the auditory localization process. Broadband stimuli were presented in virtual space from 76 roughly equidista... Abstract

Scholte AJ, Agema WR, Poldermans D, Somer ST, Holman ER, van der Wall EE, Bax JJ
Two-dimensional echocardiography is a valuable tool in visualizing and monitoring aortic valve and root abnormalities. We present a rare case of a patient with massive aortic regurgitation due to cusp aneurysm, which was accurately diagnosed by echocardiography and treated by valve replacement. A complicated course with recurrent aneurysms of the aortic wall after aortic valve replacement was remarkable in this case. Although different possible etiologies could not be determined, endocarditis an... Abstract

Ergonomics, Volume 47, Issue 8, 1 1 2004, Pages 907-921 The effects of link format and screen location on visual search of web pages. Ling J, Van Schaik P
Navigation of web pages is of critical importance to the usability of web-based systems such as the World Wide Web and intranets. The primary means of navigation is through the use of hyperlinks. However, few studies have examined the impact of the presentation format of these links on visual search. The present study used a two-factor mixed measures design to investigate whether there was an effect of link format (plain text, underlined, bold, or bold and underlined) upon speed and accuracy of...

Circulation research, Volume 95, Issue 1, 20 3 2004, Pages 58-66 Vascular endothelial growth factor overexpression in ischemic skeletal muscle enhances myoglobin expression in vivo. van Weel V, Deckers MM, Grimbergen JM, van Leuven KJ, Lardenoye JH, Schlingemann RO, van Nieuw Amerongen GP, van Bockel JH, van Hinsbergh VW, Quax PH
Therapeutic angiogenesis using vascular endothelial growth factor (VEGF) is considered a promising new therapy for patients with arterial obstructive disease. Clinical improvements observed consist of improved muscle function and regression of rest pain or angina. However, direct evidence for improved vascularization, as evaluated by angiography, is weak. In this study, we report an angiogenesis-independent effect of VEGF on ischemic skeletal muscle, ie, upregulation of myoglobin after VEGF trea... Abstract

Pathologie-biologie, Volume 52, Issue 4, 1 1 2004, Pages 186-195 Genetic predictive factors in restenosis. Monraats PS, R P Agema W, Jukema JW
Restenosis is still the main drawback of percutaneous transluminal coronary angioplasty (PTCA). It is thought to be a multifactorial process where recoil of the vessel, neointimal proliferation and thrombus formation are thought to play a role. Until now it has proven difficult to predict restenosis on clinical and procedural grounds, however, genetic epidemiology might provide more insights. In this review several genetic variables, i.e. polymorphisms that were determined in relation to resteno... Abstract

European journal of pharmacology, Volume 491, Issue 2-3, 1 1 2004, Pages 173-179 Hemodynamic characterization of left ventricular function in experimental coxsackieviral myocarditis: effects of carvedilol and metoprolol. Tschöpe C, Westermann D, Steendijk P, Noutsias M, Rutschow S, Weitz A, Schwimmbeck PL, Schultheiss HP, Pauschinger M
Background: Carvedilol, a vasodilating nonselective beta-adrenoceptor antagonist, but not metoprolol, a selective beta1-adrenoceptor antagonist, has been shown to increase the production of cardiac antiinflammatory cytokines in experimental myocarditis. However, the hemodynamic consequences of these differences had not been investigated until today. Therefore, we determined the effects of carvedilol and metoprolol on left ventricular function in a murine model of coxsackievirus B3 (CVB3)-induced... Abstract

Netherlands heart journal : monthly journal of the Netherlands Society of Cardiology and the Netherlands Heart Foundation, Volume 12, Issue 5, 1 1 2004, Pages 214-222 Recommendations and cardiological evaluation of athletes with arrhythmias: Part 2. Hoogsteen J, Bennekers JH, van der Wall EE, van Hemel NM, Wilde AA, Crijns HJ, Gorgels AP, Smeets JL, Hauer RN, Jordaens JL, Schalij MJ
Confronted with a competitive or recreational athlete, the physician has to discriminate between benign, paraphysiological and pathological arrhythmias. Benign arrhythmias do not represent a risk for SCD, nor do they induce haemodynamic consequences during athletic activities. These arrhythmias are not markers for heart disease. Paraphysiological arrhythmias are related to athletic performance. Long periods of endurance training induce changes in rhythm, conduction and repolarisation. These chan... Abstract
