The American journal of cardiology, Volume 104, Issue 9, 1 1 2009, Pages 1229-1234 Timing of noncardiac surgery after coronary artery stenting with bare metal or drug-eluting stents. van Kuijk JP, Flu WJ, Schouten O, Hoeks SE, Schenkeveld L, de Jaegere PP, Bax JJ, van Domburg RT, Serruys PW, Poldermans D
The current guidelines have recommended postponing noncardiac surgery (NCS) for > or =6 weeks after bare metal stent (BMS) placement and for > or =1 year after drug-eluting stent (DES) placement. However, much debate has ensued about these intervals. The aim of the present study was to assess the influence of different intervals between stenting and NCS and the use of dual antiplatelet therapy on the occurrence of perioperative major adverse cardiac events (MACEs). We identified 550 patien... Abstract

Anesthesia and analgesia, Volume 109, Issue 5, 1 1 2009, Pages 1403-1408 The interrelationship between preoperative anemia and N-terminal pro-B-type natriuretic peptide: the effect on predicting postoperative cardiac outcome in vascular surgery patients. Goei D, Flu WJ, Hoeks SE, Galal W, Dunkelgrun M, Boersma E, Kuijper R, van Kuijk JP, Winkel TA, Schouten O, Bax JJ, Poldermans D
Introduction: N-terminal pro-B-type natriuretic peptide (NT-proBNP) predicts adverse cardiac outcome in patients undergoing vascular surgery. However, several conditions might influence this prognostic value, including anemia. In this study, we evaluated whether anemia confounds the prognostic value of NT-proBNP for predicting cardiac events in patients undergoing vascular surgery. Methods: A detailed cardiac history, resting echocardiography, and hemoglobin and NT-proBNP levels were obtained in... Abstract

Current problems in cardiology, Volume 34, Issue 11, 1 1 2009, Pages 539-577 How to identify the asymptomatic high-risk patient? Schuijf JD, Achenbach S, Zoghbi WA, Boersma E, Raggi P, Weber M, Nagel E, Narula J, Wackers FJ, Poldermans D, Bax JJ
Worldwide, cardiovascular diseases are among the leading causes of mortality and morbidity with ever-increasing prevalence. Early targeted initiation of preventive measures would be of great benefit and can provide a major opportunity in reducing mortality and morbidity. To this end, accurate identification of individuals who are still asymptomatic but at elevated risk is essential. However, traditional risk assessment fails to recognize a substantial proportion of patients at high risk while a... Abstract

Coronary artery disease, Volume 20, Issue 7, 1 1 2009, Pages 462-466 Value of contrast echocardiography for left ventricular thrombus detection postinfarction and impact on antithrombotic therapy. Siebelink HM, Scholte AJ, Van de Veire NR, Holman ER, Nucifora G, van der Wall EE, Bax JJ
Introduction: Conventional echocardiography is often inconclusive for the presence or the absence of left ventricular (LV) thrombus. Contrast echocardiography could have additional diagnostic and therapeutic significance. This analysis investigated the value of contrast echocardiography for LV thrombus detection in patients postinfarction and the impact on choice of antithrombotic therapy. Methods: From a cohort of 991 patients undergoing routine echocardiography postinfarction, 156 patients who... Abstract

Bertini M, Delgado V, Bax JJ, Van de Veire NR
Current cardiac resynchronization therapy (CRT) devices allow manipulation of the atrioventricular (AV) and interventricular (VV) timings in order to maximize the left ventricular (LV) performance. Multiple echocardiographic and non-echocardiographic methods have been proposed to optimize AV and VV intervals but no consensus has been reached on which methodology should preferably be used. Furthermore, different physiologic conditions, such as rest and exercise, may markedly change LV loading con... Abstract

Molecular phylogenetics and evolution, Volume 54, Issue 2, 28 4 2009, Pages 336-343 Preliminary insight into the age and origin of the Labeobarbus fish species flock from Lake Tana (Ethiopia) using the mtDNA cytochrome b gene. de Graaf M, Megens HJ, Samallo J, Sibbing F
The high diversity of Cyprinid fish in Ethiopia's Lake Tana appears to be an example of ecological differentiation and assortative mating leading to rapid sympatric speciation. Lake Tana's Labeobarbus species flock consists of 15 morphological and ecological distinct species. This is the first attempt to determine the age and origin and inter-species relationships of Lake Tana's Labeobarbus species using the mtDNA cytochrome b gene. Analysis of cytchrome b sequences shows that Lak... Abstract

Heart (British Cardiac Society), Volume 95, Issue 24, 20 3 2009, Pages 1990-1996 Plaque type and composition as evaluated non-invasively by MSCT angiography and invasively by VH IVUS in relation to the degree of stenosis. van Velzen JE, Schuijf JD, de Graaf FR, Nucifora G, Pundziute G, Jukema JW, Schalij MJ, Kroft LJ, de Roos A, Reiber JH, van der Wall EE, Bax JJ
Background: Imaging of coronary plaques has traditionally focused on evaluating degree of stenosis, as the risk for adverse cardiac events increases with stenosis severity. However, the relation between plaque composition and severity of stenosis remains largely unknown. Objective: To assess plaque composition (non-invasively by multislice computed tomography (MSCT) angiography and invasively by virtual histology intravascular ultrasound (VH IVUS)) in relation to degree of stenosis.

Acta anaesthesiologica Scandinavica, Volume 54, Issue 4, 15 3 2009, Pages 470-478 Xenon and isoflurane improved biventricular function during right ventricular ischemia and reperfusion. Hein M, Roehl AB, Baumert JH, Bleilevens C, Fischer S, Steendijk P, Rossaint R
Background: Although anesthetics have some cardioprotective properties, these benefits are often counterbalanced by their negative inotropic effects. Xenon, on the other hand, does not influence myocardial contractility. Thus, xenon may be a superior treatment for the maintenance of global hemodynamics, especially during right ventricular ischemia, which is generally characterized by a high acute complication rate. Methods: The effects of 70 vol% xenon and 0.9 vol% isoflurane on biventricular fu... Abstract

Circulation, Volume 120, Issue 17, 12 2 2009, Pages 1687-1694 Short-term hemodynamic effects of cardiac resynchronization therapy in patients with heart failure, a narrow QRS duration, and no dyssynchrony. Williams LK, Ellery S, Patel K, Leyva F, Bleasdale RA, Phan TT, Stegemann B, Paul V, Steendijk P, Frenneaux M
Background: Cardiac resynchronization therapy produces both short-term hemodynamic and long-term symptomatic/mortality benefits in symptomatic heart failure patients with a QRS duration >120 ms. This is conventionally believed to be due principally to relief of dyssynchrony, although we recently showed that relief of external constraint to left ventricular filling may also play a role. In this study, we evaluated the short-term hemodynamic effects in symptomatic patients with a QRS duration Abstract

American heart journal, Volume 158, Issue 5, 3 1 2009, Pages 836-844 Incremental value of 2-dimensional speckle tracking strain imaging to wall motion analysis for detection of coronary artery disease in patients undergoing dobutamine stress echocardiography. Ng AC, Sitges M, Pham PN, Tran da T, Delgado V, Bertini M, Nucifora G, Vidaic J, Allman C, Holman ER, Bax JJ, Leung DY
Background: Interpretation of dobutamine stress echocardiogram (DSE) is often subjective and requires expert training. The purposes of this study was to determine optimal cutoff values for longitudinal, circumferential, and radial strains at peak DSE for detection of significant stenoses on coronary angiography and to investigate incremental value of combining strain measurements to wall motion analysis. Methods: In this multicenter study, 102 patients underwent concomitant DSE and coronary angi... Abstract
