Journal of the American College of Cardiology, Volume 41, Issue 12, 1 1 2003, Pages 2105-2113 Secondary prevention with folic acid: effects on clinical outcomes. Liem A, Reynierse-Buitenwerf GH, Zwinderman AH, Jukema JW, van Veldhuisen DJ

Objectives: We sought to conduct a randomized trial with folic acid 0.5 mg/day in a patient population with stable coronary artery disease (CAD). Background: Folic acid has favorable effects on vascular endothelium and lowers plasma homocysteine levels. In addition, homocysteine appears to be an independent risk factor for atherosclerotic disease. However, the value of folic acid in secondary prevention had seldom been tested. Methods: In this open-label study, 593 patients were included; 300 we... 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

Biochemical pharmacology, Volume 65, Issue 11, 1 1 2003, Pages 1875-1881 Cytosolic beta-glycosidases for activation of glycoside prodrugs of daunorubicin. de Graaf M, Pinedo HM, Quadir R, Haisma HJ, Boven E

Human cytosolic beta-glycosidase is a small monomeric enzyme that is active under physiological conditions, which might be ideal for enzyme-prodrug therapy. We have previously reported the synthesis of a galactoside (DNR-GlA3) and a glucoside (DNR-GsA3) prodrug of daunorubicin. In the present study, we established that cellular uptake of DNR-GlA3 and DNR-GsA3 was low in contrast to that of daunorubicin. Recombinant human beta-glycosidase converted both prodrugs to daunorubicin as shown by liquid... Abstract

Netherlands heart journal : monthly journal of the Netherlands Society of Cardiology and the Netherlands Heart Foundation, Volume 11, Issue 6, 1 1 2003, Pages 250-259 Heart rate variability and sympathovagal balance: pharmacological validation. Bootsma M, Swenne CA, Janssen MJ, Cats VM, Schalij MJ

Rationale: We validated heart rate (HR) and six time and six frequency domain measures of heart rate variability (HRV) as estimators of autonomic outflow in 44 young healthy male subjects. Gold standards for autonomic outflow were the Rosenblueth-Simeone factors m (sympathetic tone) and n (vagal tone), and the sympathovagal balance m·n, determined by two-stage complete autonomic blockade. Methods: Rank correlations were computed between HR and the HRV measures obtained before autonomic blockade,... Abstract

Circulation, Volume 107, Issue 19, 12 2 2003, Pages 2416-2421 Variants of toll-like receptor 4 modify the efficacy of statin therapy and the risk of cardiovascular events. Boekholdt SM, Agema WR, Peters RJ, Zwinderman AH, van der Wall EE, Reitsma PH, Kastelein JJ, Jukema JW, REgression GRowth Evaluation Statin Study Group

Background: Atherosclerosis is increasingly considered to be a chronic inflammatory process. We examined whether genetic variants of the toll-like receptor 4 (TLR4), which are correlated with impaired innate immunity and with progression of carotid atherosclerosis, are also associated with coronary atherosclerosis and predict the risk of cardiovascular events. Methods and results: Two polymorphisms of the TLR4 gene (Asp299Gly and Thr399Ile) were determined in 655 men with angiographically docume... 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

Allergy, Volume 58, Issue 4, 1 1 2003, Pages 300-305 Similar levels of nitric oxide in exhaled air in non-asthmatic rhinitis and asthma after bronchial allergen challenge. Lopuhaä CE, Koopmans JG, Jansen HM, van der Zee JS

Background: Nitric oxide in exhaled air (eNO) is elevated in allergic asthma compared with healthy subjects and has been proposed as a marker of bronchial inflammation. However, eNO is elevated to a lesser extent in allergic non-asthmatic rhinitis as well. Considering the distinctive clinical appearances of both allergic diseases, differences in eNO are expected to persist after allergen exposure. The aim of the study was to compare allergen-induced changes in eNO in house dust mite sensitized p... Abstract
