The American journal of cardiology, Volume 103, Issue 10, 1 1 2009, Pages 1451-1456 Relation of resting heart rate to prognosis in patients with idiopathic pulmonary arterial hypertension. Henkens IR, Van Wolferen SA, Gan CT, Boonstra A, Swenne CA, Twisk JW, Kamp O, van der Wall EE, Schalij MJ, Vonk-Noordegraaf A, Vliegen HW
Heart rate (HR) at rest is an important marker of prognosis in heart failure, but has not been addressed in pulmonary arterial hypertension (PAH). To determine the prognostic value of HR at rest in patients with PAH, we retrospectively analyzed 140 consecutive patients with idiopathic PAH. Electrocardiogram (ECG)-derived HR at rest was evaluated as a potential predictor of adverse prognosis (death or lung transplantation), in addition to World Health Organization functional class, 6-minute walk...

Arthritis and rheumatism, Volume 60, Issue 4, 1 1 2009, Pages 987-993 No increased risk of valvular heart disease in adult poststreptococcal reactive arthritis. van Bemmel JM, Delgado V, Holman ER, Allaart CF, Huizinga TW, Bax JJ, van der Helm-van Mil AH
Objective: Poststreptococcal reactive arthritis (ReA) is a (poly)arthritis presenting after a Streptococcus group A infection. Acute rheumatic fever (ARF), albeit caused by the same pathogen, has different risk characteristics and is considered to be a separate entity. Whereas ARF is known to cause carditis, the risk of carditis in adult poststreptococcal ReA is unknown. Consequently, the prevailing recommendations regarding long-term antibiotic prophylaxis in poststreptococcal ReA are imprecise... Abstract

Although a prognostic benefit has been shown from cardiac resynchronization therapy, questions are often directed toward the prediction of symptomatic or functional benefit. Recent multicenter trials have shown the pitfalls of current mechanical markers of left ventricular synchrony, but these negative trial results have not marked the conclusion of efforts to predict outcome. Potential new contributors to the assessment of mechanical synchrony include echocardiographic and magnetic resonance te... Abstract

American heart journal, Volume 157, Issue 5, 25 4 2009, Pages 882.e1-8 Real-time 3-dimensional echocardiography early after acute myocardial infarction: incremental value of echo-contrast for assessment of left ventricular function. Nucifora G, Marsan NA, Holman ER, Siebelink HM, van Werkhoven JM, Scholte AJ, van der Wall EE, Schalij MJ, Bax JJ
Background: Accurate and reproducible assessment of left ventricular (LV) systolic function is important in patients with acute myocardial infarction (AMI). Real-time 3-dimensional echocardiography (RT3DE) is an accurate technique, but it relies heavily on good image quality. The aim of the present study was to evaluate the incremental value of contrast-enhanced RT3DE. Methods: A total of 140 consecutive patients (58 +/- 11 years, 78% men) with ST-elevation AMI clinically underwent nonenhanced a... Abstract

Atherosclerosis, Volume 206, Issue 2, 19 3 2009, Pages 444-450 Mannose binding lectin deficiency and triglyceride-rich lipoprotein metabolism in normolipidemic subjects. Alipour A, van Oostrom AJ, Van Wijk JP, Verseyden C, Plokker HW, Jukema JW, Rabelink AJ, Castro Cabezas M
Mannose binding lectin (MBL) is one of the three initiators of complement activation and is therefore closely linked to inflammation. MBL deficiency has been associated with the generation of atherosclerosis. Since atherosclerosis, the complement system and postprandial lipemia are linked to inflammation, we studied postprandial lipoprotein metabolism in MBL deficiency. An observational study was carried out in 107 volunteers (21% MBL deficient). Classical cardiovascular risk factors were not di... Abstract

Alders M, Koopmann TT, Christiaans I, Postema PG, Beekman L, Tanck MW, Zeppenfeld K, Loh P, Koch KT, Demolombe S, Mannens MM, Bezzina CR, Wilde AA
Idiopathic Ventricular Fibrillation (IVF) is defined as spontaneous VF without any known structural or electrical heart disease. A family history is present in up to 20% of probands with the disorder, suggesting that at least a subset of IVF is hereditary. A genome-wide haplotype-sharing analysis was performed for identification of the responsible gene in three distantly related families in which multiple individuals died suddenly or were successfully resuscitated at young age. We identified a h... Abstract

European journal of cardio-thoracic surgery : official journal of the European Association for Cardio-thoracic Surgery, Volume 35, Issue 5, 9 2 2009, Pages 847-52; discussion 852-3 Wall motion score index predicts mortality and functional result after surgical ventricular restoration for advanced ischemic heart failure. Klein P, Holman ER, Versteegh MI, Boersma E, Verwey HF, Bax JJ, Dion RA, Klautz RJ
Objective: Advanced ischemic heart failure can be treated with surgical ventricular restoration (SVR). While numerous risk factors for mortality and recurrent heart failure have been identified, no plain predictor for identifying SVR patients with left ventricular damage beyond recovery is yet available. We tested echocardiographic wall motion score index (WMSI) as a predictor for mortality or poor functional result. Methods: One hundred and one patients electively operated between April 2002 an...

The Journal of general virology, Volume 90, Issue Pt 6, 4 1 2009, Pages 1408-1416 Fusion protein is the main determinant of metapneumovirus host tropism. de Graaf M, Schrauwen EJA, Herfst S, van Amerongen G, Osterhaus ADME, Fouchier RAM
Human metapneumovirus (HMPV) and avian metapneumovirus subgroup C (AMPV-C) infect humans and birds, respectively. This study confirmed the difference in host range in turkey poults, and analysed the contribution of the individual metapneumovirus genes to host range in an in vitro cell-culture model. Mammalian Vero-118 cells supported replication of both HMPV and AMPV-C in contrast to avian quail fibroblast (QT6) cells in which only AMPV-C replicated to high titres. Inoculation of Vero-118 and QT... Abstract

Echocardiography (Mount Kisco, N.Y.), Volume 26, Issue 3, 1 1 2009, Pages 315-323 The role of speckle tracking strain imaging in cardiac pacing. Tops LF, Delgado V, Bax JJ
In recent years, concerns have been raised about possible harmful effects of long-term right ventricular (RV) apical pacing. These detrimental effects may be related to changes in left ventricular (LV) mechanics during RV apical pacing. As a consequence, alternative RV pacing sites have been proposed, and in selected patients an upgrade from RV to biventricular pacing may be considered. Novel two-dimensional (2D) speckle tracking strain imaging allows detailed evaluation of LV mechanics, includi... Abstract

Recessive congenital methemoglobinemia (RCM) is a very rare disorder caused by NADH- cytochrome b5 reductase (cytb5r) deficiency. It has been classified into four types. Type I presents with mild cyanosis due to a significant deficiency of cytb5r in erythrocytes only. In type II, the deficiency occurs in all tissues and causes growth and mental retardation and other neurological impairments. RCM types I and II are caused by a defect in a single gene, which is located on chromosome 22 (locus DIA... Abstract
