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...

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...

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,...

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...

A novel functional polymorphism in the PECAM-1 gene (53G>A) is associated with progression of atherosclerosis in the LOCAT and REGRESS studies.
Elrayess MA, Webb KE, Flavell DM, Syvänne M, Taskinen MR, Frick MH, Nieminen MS, Kesäniemi YA, Pasternack A, Jukema JW, Kastelein JJ, Zwinderman AH, Humphries SE
A 53G>A polymorphism identified in the 5' untranslated region (5'UTR) of the platelet endothelial cell adhesion molecule-1 (PECAM-1) gene alters a putative shear stress responsive element (SSRE). PECAM-1 was shown to be responsive to shear stress and transient transfection of human umbilical vein endothelial cell (HUVECs) with two luciferase reporter constructs driven by the PECAM-1 promoter and 5'UTR showed a response of the 53G allele, not the 53A allele, to shear stress. Ass...

Simultaneous measurement of right and left ventricular volume by the conductance catheter technique in the newborn lamb.
Cardozo RH, de Vroomen M, van Bel F, Baan J, Steendijk P
Background: Measurement of absolute ventricular volume with the conductance catheter technique has been documented extensively for the left ventricle (LV). More recently, the same technique has been applied in studies of right ventricular (RV) performance. In the present study we performed simultaneous measurements of LV and RV volumes. Conversion of measured conductances to absolute volumes requires the assessment of slope factor alpha (α) and parallel conductance correction volume (Vc) for bot...

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...

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...

[Risk of ventricular fibrillation in patients with Wolff-Parkinson White syndrome].
Bootsma M, van der Wall EE, Schalij MJ
A 16-year-old boy suddenly fell off his stool, a 26-year-old man had persistent palpitations and a 29-year-old man was reanimated without an incriminating anamnesis. The diagnosis 'Wolff-Parkinson-White(WPW)-syndrome' was made in all three cases. The boy died as a result of postanoxic neurological injury; in the two men, further cardiac rhythm disturbances were prevented by interrupting the accessory atrioventricular connection via radiofrequency catheter ablation. In ECG databases, a...
