Subtraction electrocardiography: Detection of ischemia-induced ST displacement without the need to identify the J point.
Ter Haar CC, Man SC, Maan AC, Schalij MJ, Swenne CA
Background: When triaging a patient with acute chest pain at first medical contact, an electrocardiogram (ECG) is routinely made and inspected for signs of myocardial ischemia. The guidelines recommend comparison of the acute and an earlier-made ECG, when available. No concrete recommendations for this comparison exist, neither is known how to handle J-point identification difficulties. Here we present a J-point independent method for such a comparison. Methods: After conversion to vectorcardiog...

Diagnosis and management of aortic valve stenosis in patients with heart failure.
Kamperidis V, Delgado V, van Mieghem NM, Kappetein AP, Leon MB, Bax JJ
Aortic stenosis (AS) is the most frequent degenerative valvular heart disease in Western countries and its prevalence increases in parallel with the ageing process of the population. Heart failure (HF), defined by the presence of reduced left ventricular ejection fraction, may be present in up to a quarter of patients with severe AS, posing diagnostic and management challenges. The present article reviews the prevalence of HF in severe AS patients, discusses the diagnostic challenges and the adv...

Myocardial Infarction Alters Adaptation of the Tethered Mitral Valve.
Dal-Bianco JP, Aikawa E, Bischoff J, Guerrero JL, Hjortnaes J, Beaudoin J, Szymanski C, Bartko PE, Seybolt MM, Handschumacher MD, Sullivan S, Garcia ML, Mauskapf A, Titus JS, Wylie-Sears J, Irvin WS, Chaput M, Messas E, Hagège AA, Carpentier A, Levine RA, Leducq Transatlantic Mitral Network
Background: In patients with myocardial infarction (MI), leaflet tethering by displaced papillary muscles induces mitral regurgitation (MR), which doubles mortality. Mitral valves (MVs) are larger in such patients but fibrosis sets in counterproductively. The investigators previously reported that experimental tethering alone increases mitral valve area in association with endothelial-to-mesenchymal transition. Objectives: The aim of this study was to explore the clinically relevant situation of...

Value of Coronary Computed Tomography Angiography in Tailoring Aspirin Therapy for Primary Prevention of Atherosclerotic Events in Patients at High Risk With Diabetes Mellitus.
Dimitriu-Leen AC, Scholte AJ, van Rosendael AR, van den Hoogen IJ, Kharagjitsingh AV, Wolterbeek R, Knuuti J, Kroft LJ, Delgado V, Jukema JW, de Graaf MA, Bax JJ
Aspirin use for primary prevention in patients at high risk with diabetes mellitus (DM) is often recommended under the assumption that most patients with DM have coronary artery disease (CAD). However, not all patients may have CAD. The present study evaluated, in 425 patients at high risk with DM (without chest pain syndrome or a history of cardiac disease), the prevalence of CAD on coronary computed tomography angiography (CTA). Moreover, the association between the presence and number of trad...

Salivary Antimicrobial Peptides in Early Detection of Periodontitis.
Güncü GN, Yilmaz D, Könönen E, Gürsoy UK
In the pathogenesis of periodontitis, an infection-induced inflammatory disease of the tooth-supporting tissues, there is a complex interaction between the subgingival microbiota and host tissues. A periodontal diagnostic tool for detecting the initiation and progression of the disease, monitoring the response to therapy, or measuring the degree of susceptibility to future disease progression has been of interest for a long time. The value of various enzymes, proteins, and immunoglobulins, which...

Non-response to (statin) therapy: the importance of distinguishing non-responders from non-adherers in pharmacogenetic studies.
Trompet S, Postmus I, Slagboom PE, Heijmans BT, Smit RA, Maier AB, Buckley BM, Sattar N, Stott DJ, Ford I, Westendorp RG, de Craen AJ, Jukema JW
Purpose: In pharmacogenetic research, genetic variation in non-responders and high responders is compared with the aim to identify the genetic loci responsible for this variation in response. However, an important question is whether the non-responders are truly biologically non-responsive or actually non-adherent? Therefore, the aim of this study was to describe, within the PROspective Study of Pravastatin in the Elderly at Risk (PROSPER), characteristics of both non-responders and high respond...

Left ventricular systolic function assessment in secondary mitral regurgitation: left ventricular ejection fraction vs. speckle tracking global longitudinal strain.
Kamperidis V, Marsan NA, Delgado V, Bax JJ
Aims: Left ventricular (LV) ejection fraction (LVEF) is currently considered for the decision making of patients with mitral regurgitation (MR). However, LVEF represents change in LV volume between end-diastole and end-systole but does not characterize the intrinsic function of the myocardium. In contrast, speckle-tracking global longitudinal strain (GLS) characterizes myocardial deformation. The present study evaluated whether LV GLS may detect further impairment in LV systolic function in dila...

Enhanced characterization of calcified areas in intravascular ultrasound virtual histology images by quantification of the acoustic shadow: validation against computed tomography coronary angiography.
Broersen A, de Graaf MA, Eggermont J, Wolterbeek R, Kitslaar PH, Dijkstra J, Bax JJ, Reiber JH, Scholte AJ
We enhance intravascular ultrasound virtual histology (VH) tissue characterization by fully automatic quantification of the acoustic shadow behind calcified plaque. VH is unable to characterize atherosclerosis located behind calcifications. In this study, the quantified acoustic shadows are considered calcified to approximate the real dense calcium (DC) plaque volume. In total, 57 patients with 108 coronary lesions were included. A novel post-processing step is applied on the VH images to quanti...
