Hypertensive stress increases dispersion of repolarization.
Van Huysduynen BH, Swenne CA, Van Eck HJ, Kors JA, Schoneveld AL, Van De Vooren H, Schiereck P, Schalij MJ, Van Der Wall EE
Several electrocardiographic indices for repolarization heterogeneity have been proposed previously. The behavior of these indices under two different stressors at the same heart rate (i.e., normotensive gravitational stress, and hypertensive isometric stress) was studied. ECG and blood pressure were recorded in 56 healthy men during rest (sitting with horizontal legs), hypertensive stress (performing handgrip), and normotensive stress (sitting with lowered legs). During both stressors, heart ra...

Structural protein requirements in equine arteritis virus assembly.
Wieringa R, de Vries AA, van der Meulen J, Godeke GJ, Onderwater JJ, van Tol H, Koerten HK, Mommaas AM, Snijder EJ, Rottier PJ
Equine arteritis virus (EAV) is an enveloped, positive-stranded RNA virus belonging to the family Arteriviridae of the order Nidovirales. EAV particles contain seven structural proteins: the nucleocapsid protein N, the unglycosylated envelope proteins M and E, and the N-glycosylated membrane proteins GP(2b) (previously named G(S)), GP(3), GP(4), and GP(5) (previously named G(L)). Proteins N, M, and GP(5) are major virion components, E occurs in virus particles in intermediate amounts, and GP(4),...

Left atrial tachycardia originating from the mitral annulus-aorta junction.
Gonzalez MD, Contreras LJ, Jongbloed MR, Rivera J, Donahue TP, Curtis AB, Bailey MS, Conti JB, Fishman GI, Schalij MJ, Gittenberger-de Groot AC
Background: At the mitral annulus-aorta (MA-Ao) junction, the left atrium is continuous through the subaortic curtain with the musculature of the anterior mitral leaflet. Under experimental conditions, this region can generate abnormal electrical activity. In patients with left atrial tachycardia, we investigated whether this region could be the source of this arrhythmia. Methods and results: In 10 (28%) of 35 consecutive patients with left atrial tachycardia, the arrhythmia originated from the...

Systolic and diastolic ventricular function assessed by pressure-volume loops in the stage 21 venous clipped chick embryo.
Stekelenburg-de Vos S, Steendijk P, Ursem NT, Wladimiroff JW, Delfos R, Poelmann RE
Cardiac pressure-volume relations enable quantification of intrinsic ventricular diastolic and systolic properties independent of loading conditions. The use of pressure-volume loop analysis in early stages of development could contribute to a better understanding of the relationship between hemodynamics and cardiac morphogenesis. The venous clip model is an intervention model for the chick embryo in which permanent obstruction of the right lateral vitelline vein temporarily reduces the mechanic...

Left ventricular dyssynchrony predicts response and prognosis after cardiac resynchronization therapy.
Bax JJ, Bleeker GB, Marwick TH, Molhoek SG, Boersma E, Steendijk P, van der Wall EE, Schalij MJ
Objectives: This study was designed to predict the response and prognosis after cardiac resynchronization therapy (CRT) in patients with end-stage heart failure (HF). Background: Cardiac resynchronization therapy improves HF symptoms, exercise capacity, and left ventricular (LV) function. Because not all patients respond, preimplantation identification of responders is needed. In the present study, response to CRT was predicted by the presence of LV dyssynchrony assessed by tissue Doppler imagin...

Involvement of membrane-type matrix metalloproteinases (MT-MMPs) in capillary tube formation by human endometrial microvascular endothelial cells: role of MT3-MMP.
Plaisier M, Kapiteijn K, Koolwijk P, Fijten C, Hanemaaijer R, Grimbergen JM, Mulder-Stapel A, Quax PH, Helmerhorst FM, van Hinsbergh VW
In the endometrium, angiogenesis is a physiological process, whereas in most adult tissues neovascularization is initiated only during tissue repair or pathological conditions. Pericellular proteolysis plays an important role in angiogenesis being required for endothelial cell migration, invasion, and tube formation. We studied the expression of proteases by human endometrial microvascular endothelial cells (hEMVECs) and their involvement in the formation of capillary tubes and compared these re...

Transesophageal echocardiography-guided transvenous biopsy of an intracardiac tumor.
Scholte AJ, Frissen PH, van der Wouw PA
Transesophageal echocardiography with simultaneous fluoroscopic guidance during a transvenous biopsy of an intracardiac tumor is a valuable technique. We present the case of a 67-year-old man with a metastasis in the right atrium from which histological examination of the tumor was indicated. The inaccessible location of the primary tumor in the liver and impaired hemostasis due to cirrhosis necessitated a transvenous biopsy of the metastasis. The procedure and the associated techniques are disc...

Abnormal myocardial presynaptic norepinephrine recycling in patients with Brugada syndrome.
Kies P, Wichter T, Schäfers M, Paul M, Schäfers KP, Eckardt L, Stegger L, Schulze-Bahr E, Rimoldi O, Breithardt G, Schober O, Camici PG
Background: Life-threatening ventricular tachyarrhythmias can occur in young patients without structural heart disease (idiopathic forms). In many patients, these are typically triggered by an increased sympathetic tone, eg, by physical or mental stress. In contrast, in Brugada syndrome, ventricular tachyarrhythmias more often occur during rest or sleep when the vagal tone is predominant. Furthermore, adrenergic agonists can reduce the level of ST-segment elevation, whereas it is increased by pa...

Enhancing reverse cholesterol transport/raising HDL cholesterol: new options for prevention and treatment of cardiovascular disease.
Jukema JW, Lenselink M, de Grooth GJ, Boekholdt SM, Liem AH, Kuivenhoven JA, Kastelein JJ
High-density lipoprotein cholesterol (HDL-c) plays a crucial role in the concept of reverse cholesterol transport and has many other beneficial properties which may interfere with atherogenesis and plaque rupture. Low HDL-c levels are currently considered to be an important risk factor for the development of cardiovascular disease. However until recently no effective and safe treatment for powerfully increasing HDL-c selectively was available. This short overview describes possible new therapeut...

Is carbon monoxide-mediated cyclic guanosine monophosphate production responsible for low blood pressure in neonatal respiratory distress syndrome?
van Bel F, Latour V, Vreman HJ, Wong RJ, Stevenson DK, Steendijk P, Egberts J, Krediet TG
Infant respiratory distress syndrome (RDS) involves inflammatory processes, causing an increased expression of inducible heme oxygenase with subsequent production of carbon monoxide (CO). We hypothesized that increased production of CO during RDS might be responsible for increased plasma levels of vasodilatory cGMP and, consequently, low blood pressure observed in infants with RDS. Fifty-two infants (no-RDS, n = 21; RDS, n = 31), consecutively admitted to the neonatal intensive care unit (NICU)...

Left ventricular pacing minimizes diastolic ventricular interaction, allowing improved preload-dependent systolic performance.
Bleasdale RA, Turner MS, Mumford CE, Steendijk P, Paul V, Tyberg JV, Morris-Thurgood JA, Frenneaux MP
Background: Left ventricular (LV) pacing improves hemodynamics in patients with heart failure. We hypothesized that at least part of this benefit occurs by minimization of external constraint to LV filling from ventricular interaction. Methods and results: We present median values (interquartile ranges) for 13 heart failure patients with LV pacing systems implanted for New York Heart Association class III/IV limitation. We used the conductance catheter method to measure LV pressure and volume si...
