Biotronik wins CE Mark for 3T scans with ProMRI pacers

Biotronik said today it won CE Mark approval in the European Union for 3 Tesla full-body scans with its latest range of MR conditional pacemakers featuring its ProMRI technology. The new clearance covers single and dual chamber pacemakers from the Edora, Evity and Enitra series during ultra-high field MRI scans. The approval makes it possible to scan areas of the body typically off limits to pacemaker patients, Biotronik said. “As 3 T MRI becomes increasingly prevalent in the management of a variety of diseases, it is vital that pacemaker patients also have access to this invaluable mode of imaging. Thoracic imaging at higher field strengths has improved significantly in recent years, allowing 3 T MRI to take on a significant role in cardiac imaging for events such as cardiac perfusion, cardiac toxicity and myocardial infarction, where visualization is key in guiding clinical decision-making. With more options for cardiac imaging, we can strive to improve care for patients with pacemakers,” Dr. Matthias Schmitt of the University Hospital of South Manchester NHS Foundation Trust said in a prepared statement. Biotronik said that it is also providing an online tool to allow physicians to prospectively or retrospectively check the MR conditions of any of its devices according to device model, lead types and country regulations. “We endeavor to break down barriers that prevent device patients from safely undergoing the MRI scanning they need. With 3 T FBS ap...

CONCLUSIONS Our results found that the level of Syk was associated with the severity of CHD. From our study, we found that higher levels of Syk and inflammatory factors protein were associated with worse results of the CHD. For the first time, Syk was reported to be a promising therapeutic factor for CHD patients. PMID: 30898992 [PubMed - in process]

Introduction: Quantitative flow ratio (QFR) is a novel method enabling efficient computation of FFR from three-dimensional quantitative coronary angiography (3D QCA) and thrombolysis in myocardial infarction (TIMI) frame counting. We decided to perform a systematic review and quantitative meta-analysis of the literature to determine the correlation between the diagnosis of functionally significant stenosis obtained by QFR versus FFR and to determine the diagnostic accuracy of QFR for intermediate coronary artery stenosis.Methods: We searched PubMed, Embase, and Web of Scienc...

Congestive heart failure caused by silent ischemia and silent myocardial infarction : Diagnostic challenge in type 2 diabetes. Herz. 2019 Mar 21;: Authors: Valensi P, Meune C Abstract In asymptomatic patients with type 2 diabetes (T2D), the prevalence of silent myocardial infarction on routine electrocardiograms is about 4% while for silent myocardial ischemia it is 20-30%. Some studies showed that silent myocardial infarction is associated with an increased risk of incident heart failure (HF), whereas no prospective study has ever reported such a risk in patients with silent myocardial ...

Authors: Zimna A, Wiernicki B, Kolanowski T, Malcher A, Rozwadowska N, Labedz W, Kubaszewski L, Kurpisz M Abstract Cardiovascular diseases along with MI (myocardial infarction) lead to regional ischaemia and hypoxic conditions, which prevail after infarction. Diminished O2 saturation which is related to elevated level of hypoxia inducible factor 1 (HIF-1) transcription factor, may switch the expression of many genes. To maximize effect of therapies proposed by regenerative medicine, it is essential to verify (within different time points after MI) the expression of proangiogenic genes and their receptors that are r...

Authors: Sztechman D, Czarzasta K, Cudnoch-Jedrzejewska A, Szczepanska-Sadowska E, Zera T Abstract In the review we discuss the role of mineralocorticoid receptors (MRs) in regulation and pathological remodelling of the cardiovascular system and the therapeutic potential of pharmacological targeting of MRs in cardiovascular diseases. MRs are expressed in organs involved in cardiovascular homeostasis: brain, heart, kidneys and vessels. The excessive activation of MRs has deleterious effects on the cardiovascular system through sympatho-excitation, elevated salt appetite, and renal retention of salt with consequent p...

MicroRNA‑1 downregulation induced by carvedilol protects cardiomyocytes against apoptosis by targeting heat shock protein 60. Mol Med Rep. 2019 Mar 14;: Authors: Hu Y, Chen X, Li X, Li Z, Diao H, Liu L, Zhang J, Ju J, Wen L, Liu X, Pan Z, Xu C, Hai X, Zhang Y Abstract Myocardial infarction (MI) is the most common event in cardiovascular disease. Carvedilol, a β‑blocker with multiple pleiotropic actions, is widely used for the treatment cardiovascular diseases. However, the underlying mechanisms of carvedilol on alleviating MI are not fully understood. The aim of the present study was to invest...

AbstractAlthough Takotsubo cardiomyopathy (TCM) knowledge is increasing, the exact pathophysiology remains unclear. TCM represents 1% –2% of all troponin positive acute coronary syndromes, affects predominantly postmenopausal women, and is commonly preceded by exposure to severe physical or emotional stress. Transient wall motion abnormalities mimicking ST-elevation myocardial infarction is expected as well as increase of tropon in levels and echocardiography alterations. This case report is about a patient that as far as we know is the first case that shows the use of myocardial perfusion imaging in the acute phase ...
