Stable Low-Dose Oxygen Release Using HO/Perfluoropentane Phase-Change Nanoparticles with Low-Intensity Focused Ultrasound for Coronary Thrombolysis.

Ultrasound Med Biol 2020 Jul 6. Epub 2020 Jul 6.

Echo Lab, Department of Ultrasound Imaging, Renmin Hospital of Wuhan University, Wuhan, China.

After the onset of myocardial infarction, extensive coronary thrombus and oxygen supply insufficiency lead to severe myocardial damage and heart failure. Recently, ultrasound-irradiated phase-change nanoparticles have been recognized for their cardiovascular thrombolysis potential. Therefore, we sought to establish a novel treatment method using hydrogen peroxide (HO)/perfluoropentane (PFP) phase-change nanoparticles with low-intensity focused ultrasound (LIFU) for the simulation of acute coronary thrombolysis and myocardial preservation.

A case of very late stent thrombosis on the protruded struts at the left main coronary bifurcation.

J Cardiol Cases 2020 Jul 14;22(1):40-43. Epub 2020 May 14.

Department of Cardiology, National Hospital Organization Kyushu Medical Center, Fukuoka, Japan.

A previous autopsy study has revealed that malapposed or protruded struts in the coronary bifurcation were a risk factor for very late stent thrombosis (VLST); however, a live clinical case has not yet been reported due to difficulty in observation at the VLST site. In this case, a 56-year-old male patient underwent a zotarolimus-eluting stent implantation in the proximal left anterior descending artery for acute myocardial infarction 3 years previously and had been treated with dual antiplatelet therapy. The patient experienced chest pain and suddenly collapsed due to acute coronary syndrome caused by a huge thrombus in the left main coronary bifurcation. Read More

[Troponin elevation in acute ischemic stroke-unspecific or acute myocardial infarction? : Diagnostics and clinical implications].

Herz 2020 Jul 6. Epub 2020 Jul 6.

I. Medizinische Klinik, Universitätsmedizin Mannheim (UMM), Medizinische Fakultät Mannheim, Universität Heidelberg, Theodor-Kutzer-Ufer 1-3, 68167, Mannheim, Deutschland.

Routine determination of troponin levels is recommended for all patients with acute ischemic stroke. In 20-55% of these patients the troponin levels are elevated, which may be caused by ischemic as well as non-ischemic myocardial damage and particularly neurocardiogenic myocardial damage. In patients with acute ischemic stroke, the prevalence of previously unknown coronary heart disease is reported to be up to 27% and is prognostically relevant for these patients; however, relevant coronary stenoses are less frequently detected in stroke patients with troponin elevation compared to patients with non-ST elevation myocardial infarction.

COPD and acute myocardial infarction.

Eur Respir Rev 2020 Jun 23;29(156). Epub 2020 Jun 23.

Dept of Cardiology, Leiden University Medical Centre, Leiden, The Netherlands.

COPD is strongly associated with cardiovascular disease, in particular acute myocardial infarction (AMI). Besides shared risk factors, COPD-related factors, such as systemic inflammation and hypoxia, underlie the pathophysiological interaction between COPD and AMI. The prevalence of COPD amongst AMI populations ranges from 7% to 30%, which is possibly even an underestimation due to underdiagnoses of COPD in general. Read More

Why, When and How Should Clinicians Use Physiology in Patients with Acute Coronary Syndromes?

Interv Cardiol 2020 Apr 4;15:e05. Epub 2020 Jun 4.

Oxford Heart Centre, NIHR Biomedical Research Centre, Oxford University Hospitals Oxford, UK.

Current data support the use of coronary physiology in patients with acute coronary syndrome (ACS). In patients with ST-elevation MI, the extent of myocardial damage and microvascular dysfunction create a complex conundrum to assimilate when considering clinical management and risk stratification. In this setting, the index of microcirculatory resistance emerged as an accurate tool to identify patients at risk of suboptimal myocardial reperfusion after primary percutaneous coronary intervention who may benefit from novel adjunctive therapies.

Initial experience regarding the safety and yield of rest-stress myocardial perfusion imaging in emergency department patients with mildly abnormal high-sensitivity cardiac troponins.

J Nucl Cardiol 2020 Jun 17. Epub 2020 Jun 17.

Department of Cardiovascular Imaging, Heart and Vascular Institute, Cleveland Clinic, Cleveland, OH, USA.

Background: With high-sensitivity troponin testing, approximately a third of patients presenting to emergency departments (EDs) with suspected acute coronary syndromes will have mildly abnormal values. However, data regarding rest-stress myocardial perfusion imaging (MPI) in these patients are limited. We hypothesize that stress testing is safe and that the yield for detecting myocardial ischemia is associated with risk stratification by the HEART score. Read More

Departamento de Fisiología - Facultad de Medicina, Fluorescence Imaging Group, Avda. Arzobispo Morcillo 2, Universidad Autónoma de Madrid, Madrid, 28029, Spain.

Fast and precise localization of ischemic tissues in the myocardium after an acute infarct is required by clinicians as the first step toward accurate and efficient treatment. Nowadays, diagnosis of a heart attack at early times is based on biochemical blood analysis (detection of cardiac enzymes) or by ultrasound-assisted imaging. Alternative approaches are investigated to overcome the limitations of these classical techniques (time-consuming procedures or low spatial resolution). Read More

Imaging of Injectable Hydrogels Delivered into Myocardium with SPECT/CT.

Adv Healthc Mater 2020 Jun 15:e2000294. Epub 2020 Jun 15.

Department of Bioengineering, University of Pennsylvania, 210 33rd Street, Philadelphia, PA, 19104, USA.

Injectable hydrogels are being widely explored for treatment after myocardial infarction (MI) through mechanical bulking or the delivery of therapeutics. Despite this interest, there have been few approaches to image hydrogels upon injection to identify their location, volume, and pattern of delivery, features that are important to understand toward clinical translation. Using a hyaluronic acid (HA) hydrogel as an example, the aim of this study is to introduce radiopacity to hydrogels by encapsulating a clinically used contrast agent (Omnipaque Iohexol, GE Healthcare) for imaging upon placement in the myocardium.

Association of Myocardial Injury With Serum Procalcitonin Levels in Patients With ST-Elevation Myocardial Infarction.

JAMA Netw Open 2020 Jun 1;3(6):e207030. Epub 2020 Jun 1.

Cardiology and Angiology, University Clinic of Internal Medicine III, Medical University of Innsbruck, Innsbruck, Austria.

Importance: Myocardial tissue injury due to acute ST-elevation myocardial infarction (STEMI) initiates an inflammatory response that leads to a release of systemic inflammatory biomarkers, including C-reactive protein (CRP) and white blood cells, consequently reducing the usefulness of these routine biomarkers for identifying concomitant infections. The clinical role of procalcitonin (PCT), a promising marker of bacterial infection, to detect concomitant infection in acute STEMI is unknown, mainly because it is unclear whether myocardial injury per se induces systemic PCT release.

Objective: To investigate the release of serum PCT in the acute setting of STEMI (24 and 48 hours after primary percutaneous coronary intervention) and to elucidate any associations with myocardial injury markers through a comprehensive assessment by cardiac magnetic resonance (CMR) imaging.

[Spontaneous coronary artery dissection : primum nihil nocere].

Rev Med Suisse 2020 Jun;16(696):1153-1158

Service de cardiologie, HUG, 1211 Genève 14.

Spontaneous coronary artery dissection (SCAD) is an important cause of acute coronary syndrome, myocardial infarction and sudden cardiac death, among young patient with little/no traditional cardiovascular risk factors. Historically SCAD was considered as a rare pathology, associated primarily with pregnancy and the peripartum period. In recent years, SCAD diagnosis improved thanks to data derived from large registries, thanks to the increased use of diagnostic coronary angiography and the availability of intracoronary imaging.

Aims: Takotsubo syndrome (TTS) is an acute heart failure syndrome, which shares many features with acute coronary syndrome (ACS). Although TTS was initially described with angiographically normal coronary arteries, smaller studies recently indicated a potential coexistence of coronary artery disease (CAD) in TTS patients. This study aimed to determine the coexistence, features, and prognostic role of CAD in a large cohort of patients with TTS. Read More

Intravenously delivered mesenchymal stem cells prevent microvascular obstruction formation after myocardial ischemia/reperfusion injury.

Basic Res Cardiol 2020 May 25;115(4):40. Epub 2020 May 25.

Department of Cardiology, Drum Tower Hospital, State Key Laboratory of Pharmaceutical Biotechnology, Medical School of Nanjing University, No. 321 Zhongshan Road, Nanjing, 210008, China.

Microvascular obstruction (MVO) after primary percutaneous coronary intervention (pPCI) is identified as an independent risk factor for poor prognosis in patients with acute myocardial infarction (AMI). The inflammatory response induced by ischemia and reperfusion (I/R) injury is considered one of the main mechanisms of MVO. Mesenchymal stem cells (MSCs) are a unique stromal cell type that confers an immunomodulatory effect in cardiac disease. Read More

Comparative left ventricular mechanical deformation in acute apical variant stress cardiomyopathy and acute anterior myocardial infarction utilizing 2-dimensional longitudinal strain imaging.

Echocardiography 2020 Jun 21;37(6):832-840. Epub 2020 May 21.

Division of Cardiovascular Medicine, University of Massachusetts Medical School, Worcester, MA, USA.

Aims: Despite three decades of study, it is still challenging to discriminate acute apical variant stress cardiomyopathy (AVSCM) from acute left anterior descending-myocardial infarction (LAD-MI) at the time of presentation. A biomarker or practical imaging modality that can differentiate these two entities is highly desirable. Our objective was to characterize left ventricular (LV) mechanical deformation using 2-dimensional (2D) echocardiographic strain imaging in an attempt to discriminate AVSCM from LAD-MI at presentation.
