Ischaemia/reperfusion (I/R) injury can lead to severe arrhythmia and aggravate myocardial damage. Exosomes are small-membrane vesicles that play a protective role in myocardial I/R injury. This study aimed to explore the protective effects of ischaemic preconditioning (IPC)-induced serum exosomes (IPC-Exo) on myocardial I/R injury in rats and its underlying mechanism. Serum exosomes were extracted from IPC rats and quantified using a bicinchoninic acid assay kit. IPC-Exo (50 μg) was injected into the infarcted myocardium immediately after ligation...

Transcatheter aortic valve replacement (TAVR) is an alternative treatment option for patients with severe aortic stenosis. Although rarely described, mitral valve perforation because of mechanical stimulation due to low deployment of the prosthesis and the association with infective endocarditis, are potentially life-threatening complications that physicians should be aware of because patients should not be suitable for further surgical or percutaneous management. Herein, we present a case of an 88-year-old man presenting with worsening heart failure 6 months after TAVR...

An 88-year-old male with nonvalvular atrial fibrillation (NVAF) and severe congestive heart failure (HF), was admitted to the Neurological Intensive Care Unit because of the acute onset of aphasia and left hemiplegia. Transthoracic echocardiography revealed a left atrial (LA) cavity thrombus. Its "fatal" distal embolization to abdominal aorta occurred in a few days. These observations should lead to a cautious approach in proposing a percutaneous closure of LA appendage in older NVAF patients, with HF and/or left ventricular dysfunction and larger LA volumes, who are not adequately anticoagulated...

Transthoracic echocardiography is a useful diagnostic technique for the identification of intracardiac and extracardiac masses, which can evaluate morphologic properties of the masses such as their location, attachment, shape, size, mobility, and possible hemodynamic-related implications. Apart from physiological variants and structural normal mimickers, echocardiography can detect principal intracardiac masses such as neoplasms, thrombi, vegetation, and extracardiac masses such as metastatic lesions. Moreover, transesophageal echocardiography can provide further details and provide higher accuracy in case a deeper examination of the mass is needed...

Introduction Chronic kidney disease (CKD) carries a significant association with cardiac diseases, which suggests a minor reduction in the glomerular filtration rate (GFR) can act as an independent risk factor for causing cardiovascular abnormalities. Patients of CKD having cardiovascular disease (CVD) had three to thirty times higher risk of mortality as compared to the general population. In addition, mortality among cardiovascular patients has been found to be twofold higher in CKD stage 2 patients and three-fold higher in patients with stage 3 CKD, when collated to patients with normal renal function...

Background: Streptococcus gallolyticus , formerly known as one of the Streptococcus bovis group, is frequently associated with endocarditis. Current guidelines recommended diagnostic work-up for endocarditis among patients with S. gallolyticus bacteremia. However, S. gallolyticus subsp. pasteurianus , was found to be associated with neonatal sepsis and liver diseases and is less commonly associated with endocarditis compared with S. gallolyticus subsp. gallolyticus . Our study aimed to identify the risk factors for S...

Given the inconsistent results on the prognostic significance of triglycerides (TGs), the purpose of the present study was to investigate the association of plasma TGs with left ventricular mass (LVM) in hypertensive patients. We studied 760 never treated, non diabetic, hypertensive patients. Τransthoracic echocardiography was performed and LVMI was calculated according to the Devereux formula, adjusted to body surface area. Triglycerides were associated with LVMI after adjustment for age, gender, systolic blood pressure (SBP), smoking and fasting glucose (b = 0...

The prevalence of diabetic metabolic derangement (DMetD) has increased dramatically over the last decades. Although there is increasing evidence that DMetD is associated with cardiac dysfunction, the early DMetD-induced myocardial alterations remain incompletely understood. Here, we studied early DMetD-related cardiac changes in a clinically relevant large animal model. DMetD was established in adult male Göttingen miniswine by streptozotocin injections and a high-fat, high-sugar diet, while control animals remained on normal pig chow...

A rise in heart disease incidence in women after menopause has led to investigations into the role of female sex hormones on cardiac function. Although various adverse changes in cardiac contractile function following loss of female sex hormones have been reported, a clear mechanism of action has never been characterized. In order to examine whether an elevation in oxidative stress is a major cause of cardiac contractile dysfunction after female sex hormone deprivation, cardiac functions of ovariectomized rats with and without supplementation of superoxide scavenger tempol were compared to those of sham-operated controls...
