J Med Ultrason (2001) 2022 Jun 27. Epub 2022 Jun 27.

Department of Cardiology, Graduate School of Medical Sciences, Nagoya City University, 1 Kawasumi, Mizuho-cho, Mizuho-ku, Nagoya, 467-8601, Japan.

Since Japan is experiencing a super-aged society, the number of heart failure patients (HF) is increasing remarkably. In particular, the increase in heart failure with preserved ejection fraction (HFpEF), which is common in the elderly, has characterized the last decade. The diagnosis of HFpEF by assessment of left ventricular (LV) diastolic dysfunction, which is also referred to as diastolic heart failure, is an important role assigned to echocardiography.

DIAGNOSIS AND MANAGEMENT OF SUSPECTED CONGESTIVE HEART FAILURE SECONDARY TO DILATED CARDIOMYOPATHY IN A SAND TIGER SHARK () WITH ESTABLISHMENT OF PRELIMINARY NORMAL ECHOCARDIOGRAPHIC INDICES.

J Zoo Wildl Med 2022 Jun;53(2):363-372

Veterinary Specialty Center, Buffalo Grove, IL 60089, USA.

Elasmobranch cardiac anatomy and physiology has been well described; however, there is a dearth of information regarding cardiac disease. In support of a clinical case of suspected congestive heart failure in a 22-yr-old male sand tiger shark (), a study was undertaken to identify feasible echocardiographic imaging planes and preliminary indices for this species. Eleven echocardiograms were performed on six apparently healthy sand tiger sharks. Read More

Case report: hypoglycemia secondary to methimazole-induced insulin autoimmune syndrome in young Taiwanese woman with Graves' disease.

Medicine (Baltimore) 2022 Jun 24;101(25):e29337. Epub 2022 Jun 24.

Division of Endocrinology and Metabolism, Department of Internal Medicine, Kaohsiung Medical University, Kaohsiung, Taiwan.

Rationale: Hypoglycemia is an emergent condition with many causes, including underlying diabetes mellitus either with the use of insulin or oral anti-diabetic medications for glucose control, and organ (heart, hepatic, or renal) failure. Insulin autoimmune syndrome (IAS) can also cause hypoglycemia, however it is relatively difficult to diagnose as it is rare clinically. Although uncommon, IAS can be life threatening in patients with persistent hypoglycemia. Read More

A combination of severe complications in a case of infective endocarditis: Dehiscence of prosthetic aortic valve, aortic dissection, pseudoaneurysm, and hematoma causing right ventricular collapse.

Echocardiography 2022 Jun 27. Epub 2022 Jun 27.

Department of Cardiovascular Surgery, Basaksehir Cam & Sakura City Hospital, Istanbul, Turkey.

Prosthetic valve endocarditis with mechanical complications causing pulmonary edema is fatal, therefore it needs to be diagnosed early and should be treated surgically in emergency setting. Transesophageal echocardiogram is crucial for recognizing the mechanical complications, which can be encountered on daily practice, but the coexistence of complications occurring on different mechanism is rather uncommon. Herein, we report a 21-year-old gentleman presenting with acute heart failure, whose imaging tests showed a combination of dehiscence of mechanical aortic valve prosthesis, aortic dissection, pseudoaneurysm, and hematoma causing right ventricular collapse.

Impact of different training modalities on high-density lipoprotein function in HFpEF patients: a substudy of the OptimEx trial.

ESC Heart Fail 2022 Jun 23. Epub 2022 Jun 23.

Laboratory of Molecular and Experimental Cardiology, Technische Universität Dresden, Heart Center Dresden, Dresden, Germany.

Aims: In heart failure with preserved ejection fraction (HFpEF), the reduction of nitric oxide (NO)-bioavailability and consequently endothelial dysfunction leads to LV stiffness and diastolic dysfunction of the heart. Besides shear stress, high-density lipoprotein (HDL) stimulates endothelial cells to increased production of NO via phosphorylation of endothelial nitric oxide synthase (eNOS). For patients with heart failure with reduced ejection fraction, earlier studies demonstrated a positive impact of exercise training (ET) on HDL-mediated eNOS activation. Read More

Sensors (Basel) 2022 Jun 7;22(12). Epub 2022 Jun 7.

College of Science and Engineering, Hamad Bin Khalifa University, Doha 34110, Qatar.

Cardiovascular diseases (CVD) are the leading cause of death worldwide. People affected by CVDs may go undiagnosed until the occurrence of a serious heart failure event such as stroke, heart attack, and myocardial infraction. In Qatar, there is a lack of studies focusing on CVD diagnosis based on non-invasive methods such as retinal image or dual-energy X-ray absorptiometry (DXA). Read More

Cardiac I-IBG Imaging in Heart Failure.

Pharmaceuticals (Basel) 2022 May 25;15(6). Epub 2022 May 25.

Department of Radiology and Nuclear Medicine, Amsterdam University Medical Center, Location Amsterdam Medical Center, University of Amsterdam, Meibergdreef 9, 1105 AZ Amsterdam, The Netherlands.

Cardiac sympathetic upregulation is one of the neurohormonal compensation mechanisms that play an important role in the pathogenesis of chronic heart failure (CHF). In the past decades, cardiac I-IBG scintigraphy has been established as a feasible technique to evaluate the global and regional cardiac sympathetic innervation. Although cardiac I-IBG imaging has been studied in many cardiac and neurological diseases, it has extensively been studied in ischemic and non-ischemic CHF. Read More

Non-Invasive Estimation of Right Atrial Pressure Using a Semi-Automated Echocardiographic Tool for Inferior Vena Cava Edge-Tracking.

J Clin Med 2022 Jun 7;11(12). Epub 2022 Jun 7.

Fondazione Toscana G. Monasterio, 56124 Pisa, Italy.

The non-invasive estimation of right atrial pressure () would be a key advancement in several clinical scenarios, in which the knowledge of central venous filling pressure is vital for patients' management. The echocardiographic estimation of RAP proposed by Guidelines, based on inferior vena cava (IVC) size and respirophasic collapsibility, is exposed to operator and patient dependent variability. We propose novel methods, based on semi-automated edge-tracking of IVC size and cardiac collapsibility (cardiac caval index-CCI), tested in a monocentric retrospective cohort of patients undergoing echocardiography and right heart catheterization (RHC) within 24 h in condition of clinical and therapeutic stability (170 patients, age 64 ± 14, male 45%, with pulmonary arterial hypertension, heart failure, valvular heart disease, dyspnea, or other pathologies).

The Role of Circulating Collagen Turnover Biomarkers and Late Gadolinium Enhancement in Patients with Non-Ischemic Dilated Cardiomyopathy.

Diagnostics (Basel) 2022 Jun 10;12(6). Epub 2022 Jun 10.

Department of Internal Medicine, Iuliu Hatieganu University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania.

Background: Myocardial scarring is a primary pathogenetic process in nonischemic dilated cardiomyopathy (NIDCM) that is responsible for progressive cardiac remodeling and heart failure, severely impacting the survival of these patients. Although several collagen turnover biomarkers have been associated with myocardial fibrosis, their clinical utility is still limited. Late gadolinium enhancement (LGE) determined by cardiac magnetic resonance imaging (CMR) has become a feasible method to detect myocardial replacement fibrosis. Read More

Complementary Role of Combined Indirect and Direct Cardiac Sympathetic (Hyper)Activity Assessment in Patients with Heart Failure by Spectral Analysis of Heart Rate Variability and Nuclear Imaging: Possible Application in the Evaluation of Exercise Training Effects.

J Cardiovasc Dev Dis 2022 Jun 5;9(6). Epub 2022 Jun 5.

Department of Biomedicine and Prevention, University of Rome Tor Vergata, 00133 Rome, Italy.

In chronic heart failure (CHF), abnormalities in cardiac autonomic control, characterized by sympathetic overactivity, contribute to the progression of the disease and are associated with an unfavorable prognosis. Assessing cardiac autonomic status is clinically important in the management of patients with CHF. To this aim, heart rate variability (HRV) analysis has been extensively used as a non-invasive tool for assessing cardiac autonomic regulation, and has been shown to predict the clinical outcome in patients with CHF.
