Peripheral Blood MicroRNA-21 as a Predictive Biomarker for Heart Failure With Preserved Ejection Fraction in Old Hypertensives.

Background: Heart failure with preserved ejection fraction (HFpEF) is a major health issue with high morbidity and mortality. The epidemiology and the factors that cause HFpEF have not been fully clarified, while accurate predictive biomarkers are lacking. Our aim was to determine whether levels of microRNA-21 (miR-21) in peripheral blood monocytes, which play a critical role in many pathophysiological pathways of hypertensive heart disease, can predict the occurrence of HFpEF in older hypertensives, as well as the associated mortality and morbidity.

Visceral fat and cardiometabolic future in children and adolescents: a critical update.

Cardiovascular disease (CVD) is a process whose pathogenetic mechanisms start very early in life. Recently, the importance of visceral adipose tissue (VAT) has been highlighted in the development of CVD. VAT does not always depend on body mass index (BMI) and has been implicated in unfavorable metabolic activity and cardiovascular adverse events.

Injecting a ventricular tachycardia into the heart-Α unique case report.

Introduction: A 52-year-old woman presented with a complex ventricular arrhythmia in an intraoperative context, during kyphoplasty for an osteoporotic fracture of a lumbar vertebra. The subject showed no indications of a previous cardiovascular condition.

Methods And Results: Causes of arrhythmias associated with the procedure were excluded.

Differences in MicroRNA Expression in Pericoronary Adipose Tissue in Coronary Artery Disease Compared to Severe Valve Dysfunction.

Pericoronary adipose tissue (PCAT) is a source of microRNAs (miRs) that act as messengers for intercellular communication. We investigated whether the PCAT surrounding significant coronary atherosclerotic lesions shows specific miR expression patterns compared with PCAT surrounding plaque-free segments. We included 49 patients with 3-vessel coronary artery disease (CAD) and 19 patients with severe valvular disease but no CAD, who underwent elective cardiac surgery.

Effects of Sodium-Glucose Cotransporter-2 Inhibitors on Cardiac Structural and Electrical Remodeling: From Myocardial Cytology to Cardiodiabetology.

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have changed the clinical landscape of diabetes mellitus (DM) therapy through their favourable effects on cardiovascular outcomes. Notably, the use of SGLT2i has been linked to cardiovascular benefits regardless of DM status, while their pleiotropic actions remain to be fully elucidated. What we do know is that SGLT2i exert beneficial effects even at the level of the myocardial cell and that these are linked to an improvement in the energy substrate, resulting in less inflammation and fibrosis.

Hybrid imaging of neuroendocrine tumors in the heart: Union is strength.

Cardiac neuroendocrine tumors (NETs) are particularly rare tumors that can lead to a very poor clinical outcome, partly because of metastases but mainly because of manifestations of the hormonal activity they exhibit. Prompt diagnosis is important in order to start the most effective treatment for their removal or management, with the fewest complications. They are often difficult to diagnose, especially in their early stages.

Long-term prognostic value of myocardin expression levels in non-ischemic dilated cardiomyopathy.

The mortality of patients with non-ischemic dilated cardiomyopathy (NIDCM) remains substantial. We evaluated gene expression levels of myocardin, an early cardiac gene, in the peripheral blood cells of NIDCM patients as a prognostic biomarker in their long-term outcome and mortality from congestive HF (CHF). We retrospectively analyzed 101 consecutives optimally treated NIDCM patients of Cretan origin who were enrolled from the HF clinic of our hospital from November 2005 to December 2008.

Peripheral Blood MicroRNAs as Potential Biomarkers of Myocardial Damage in Acute Viral Myocarditis.

Background: microRNAs (miRs) have emerged as important modulators of cardiovascular development and disease. Our aim was to determine whether cardiac-related miRs such as miR-21-5p and miR-1-3p were differentially expressed in acute viral myocarditis and whether any of them was related with the extent of myocardial damage and left ventricular dysfunction.

Methods: We enrolled 40 patients with acute viral myocarditis.

Bicuspid aortic valve endocarditis caused by Gemella sanguinis: Case report and literature review.

Gemella species are catalase-negative, facultative anaerobic, Gram-positive cocci, which are part of the human oral microbiome and may occasionally cause systemic infections. Infective endocarditis (IE) has been reported as the most common infection caused by Gemella species. We report the first case of IE due to Gemella sanguinis in Greece, in a patient with bicuspid aortic valve and review the available literature.
