Why do patients with ischemic cardiomyopathy and a substantial amount of viable myocardium not always recover in function after revascularization?
Schinkel AF, Poldermans D, Rizzello V, Vanoverschelde JL, Elhendy A, Boersma E, Roelandt JR, Bax JJ
Objective: In patients with ischemic cardiomyopathy and a substantial amount of dysfunctional but viable myocardium, myocardial revascularization may improve left ventricular ejection fraction. The aim of this study was to evaluate why not all patients with a substantial amount of viable tissue recover in function after revascularization. Methods: A total of 118 consecutive patients with a depressed left ventricular ejection fraction (on average 29% +/- 6%) due to chronic coronary artery disease...

Comparison of functional recovery of mildly hypokinetic versus severely dysfunctional left ventricular segments after revascularization in patients with ischemic cardiomyopathy.
Rizzello V, Biagini E, Schinkel AF, Bountioukos M, Boersma E, Vourvouri EC, Sozzi FB, Elhendy A, Roelandt JR, Poldermans D, Bax JJ
Dysfunctional left ventricular (LV) segments showing contractile reserve during dobutamine stress echocardiography (DSE) are considered viable myocardium; functional recovery is expected after revascularization. Many segments, however, particularly mildly hypokinetic segments, do not recover. The reason for this failure is unknown. Two-dimensional echocardiography at rest and low-high-dose DSE were performed before revascularization in 114 consecutive patients with ischemic cardiomyopathy. Two-d...

Cyclic appropriate mode switching and inappropriate back switching of a biventricular pacemaker during atrial tachyarrhythmia.
van Erven L, Molhoek SG, van der Wall EE, Schalij MJ
In patients with resynchronization devices and intact intrinsic AV conduction, atrial tachyarrhythmias may give rise to high ventricular rates, resulting in inhibition of (bi)ventricular pacing and concomitant lack of therapeutic effects of the device. This report presents a patient with atrial arrhythmias in whom mode switching and back switching of the biventricular pacemaker occurred, due to special timing of the atrial and ventricular deflections. This case report stresses the importance of...

Hepatic low-density lipoprotein receptor-related protein deficiency in mice increases atherosclerosis independent of plasma cholesterol.
Espirito Santo SM, Pires NM, Boesten LS, Gerritsen G, Bovenschen N, van Dijk KW, Jukema JW, Princen HM, Bensadoun A, Li WP, Herz J, Havekes LM, van Vlijmen BJ
The low-density lipoprotein (LDL) receptor-related protein (LRP) has a well-established role in the hepatic removal of atherogenic apolipoprotein E (APOE)-rich remnant lipoproteins from plasma. In addition, LRP recognizes multiple distinct pro- and antiatherogenic ligands in vitro. Here, we investigated the role of hepatic LRP in atherogenesis independent of its role in removal of APOE-rich remnant lipoproteins. Mice that allow inducible inactivation of hepatic LRP were combined with LDL recepto...

Cholesteryl ester transfer protein concentration is associated with progression of atherosclerosis and response to pravastatin in men with coronary artery disease (REGRESS).
Klerkx AH, de Grooth GJ, Zwinderman AH, Jukema JW, Kuivenhoven JA, Kastelein JJ
Background: The TaqIB polymorphism in the cholesteryl ester transfer protein (CETP) gene is associated with HDL-C, progression of coronary artery disease (CAD) and response to pravastatin treatment in men with angiographically proven CAD (REGRESS). We hypothesized that differences in CETP concentration could explain these associations and now investigated whether CETP concentration is an independent determinant of these parameters. Materials and methods: Plasma CETP concentrations at baseline an...

Genetic programme of cardiogenesis: implications for therapeutic application.
van Tuyn J, de Vries AA, van der Laarse A, Schalij MJ, van der Wall EE, Atsma DE
It has become accepted that new cardiomyocytes can be derived from stem cells. Although the potential for therapeutic application is evident, the reported efficiency of differentiation varies greatly from 0.02 to 54%. To obtain clinically relevant numbers of newly differentiated cardiac cells, stem cell differentiation should be as efficient as possible. A plausible way to increase the efficiency of differentiation of stem cells into cardiomyocytes is through the introduction of cardiac specific...

Interaction between a genetic variant of the platelet fibrinogen receptor and fibrinogen levels in determining the risk of cardiovascular events.
Boekholdt SM, Peters RJ, de Maat MP, Zwinderman AH, van Der Wall EE, Reitsma PH, Jukema JW, Kastelein JJ
Background: The PlA1A2 polymorphism of glycoprotein IIIa (GPIIIa), which affects postoccupancy signaling by the platelet fibrinogen receptor IIbIIIa, has been investigated as a potential genetic risk factor for cardiovascular events in numerous studies, without consistent results. We investigated whether the effect of this genetic variant of the platelet fibrinogen receptor on the risk of cardiovascular events is affected by fibrinogen plasma levels. Methods: The GPIIIa PlA1A2 polymorphism and f...

Additive benefits of pravastatin and aspirin to decrease risks of cardiovascular disease: randomized and observational comparisons of secondary prevention trials and their meta-analyses.
Hennekens CH, Sacks FM, Tonkin A, Jukema JW, Byington RP, Pitt B, Berry DA, Berry SM, Ford NF, Walker AJ, Natarajan K, Sheng-Lin C, Fiedorek FT, Belder R
Background: In randomized trials of secondary prevention, pravastatin sodium and aspirin reduce risks of cardiovascular disease. Pravastatin has a predominantly delayed antiatherogenic effect, and aspirin has an immediate antiplatelet effect, raising the possibility of additive clinical benefits. Methods: In 5 randomized trials of secondary prevention with pravastatin (40 mg/d), comprising 73 900 patient-years of observation, aspirin use was also prescribed in varying frequencies, and data were...

Radiofrequency catheter ablation of ventricular tachycardia guided by intracardiac echocardiography.
Jongbloed MR, Bax JJ, van der Burg AE, Van der Wall EE, Schalij MJ
Aims: Ventricular tachycardia (VT) frequently has an anatomical substrate. Identification of areas prone to arrhythmogenicity facilitates radiofrequency catheter ablation (RFCA). Furthermore, direct monitoring of complications potentially increases safety of RFCA. The aim of this study was to evaluate the feasibility of guiding RFCA of VT with intracardiac echocardiography (ICE), in order to improve outcome and procedural safety. Methods and results: Eleven patients (age 59 +/- 15 years) with dr...

Accurate and reproducible mitral valvular blood flow measurement with three-directional velocity-encoded magnetic resonance imaging.
Westenberg JJ, Danilouchkine MG, Doornbos J, Bax JJ, van der Geest RJ, Labadie G, Lamb HJ, Versteegh MI, de Roos A, Reiber JH
A new method for quantifying the transvalvular flow through the mitral valve (MV) based on three-directional velocity-encoded magnetic resonance imaging (MRI) is presented. For thirty time phases during one cardiac cycle, the three-dimensional (3D) velocity vector field of the blood flow is reconstructed from the MRI measurement. Retrospectively, for each time phase, the MV-plane is indicated manually in the velocity data and the flow through this plane is determined, representing the MV flow. M...
