The association between uric acid (UA) on one side and systemic hypertension (Htn), dyslipidemia, glucose intolerance, overweight, fatty liver, renal disease and cardiovascular disease (CVD) on the other side is well recognized. However, the causal relationship between UA and these different clinical problems is still debatable. The recent years have witnessed hundreds of experimental and clinical trials that favored the opinion that UA is a probable player in the pathogenesis of these disease entities. These studies disclosed the strong association between hyperuricemia and metabolic syndrome (MS), obesity, Htn, type 2 diabetes mellitus (DM), non-alcoholic fatty liver disease, hypertriglyceridemia, acute kidney injury, chronic kidney disease (CKD), coronary heart disease (CHD), heart failure and increased mortality among cardiac and CKD patients...

BACKGROUND: Prognosis of hypertrophic cardiomyopathy (HCM) is particularly heterogeneous. Patients with nonobstructive HCM (NOCM) are thought to be at relatively low-risk as compared with obstructive HCM (HOCM) with no need of major treatment options. However, available evidence of NOCM comes mainly from tertiary centers where a referral bias is likely to occur. Aim of this study was to perform a systematic review and meta-analysis of the published literature on hypertrophic cardiomyopathy (HCM) in order to outline differences in presenting features and long-term outcome between NOCM and HOCM...

BACKGROUND: Diabetes mellitus type 2 (T2DM) often co-exists with hypertension, and this aggregation of co-morbidities amplifies the risk for future cardiovascular events. Therefore, it appears crucial to understand the essence of choosing oral and non-insulin injectable anti-diabetic drugs (ADs) with a favorable hemodynamic impact that could partially attenuate the increased baseline cardiovascular risk. OBJECTIVE: We sought to evaluate the effect of ADs on blood pressure (BP) indices and to assess the potential role of certain ADs towards hypertension treatment...

There remains a need for large animal models to evaluate tissue engineered vascular grafts (TEVGs) under arterial pressure to provide preclinical data for future potential human clinical trials. We present a comprehensive method for the interrogation of TEVGs, using an ovine bilateral arteriovenous shunt implantation model. Our results demonstrate that this method can be performed safely without complications, specifically acute heart failure, steal syndrome, and hypoxic brain injury and is a viable experimental paradigm...

Heart failure has a high prevalence in the general population. Morbidity and mortality of heart failure patients remain high, despite improvements in drug therapy, implantable cardioverter-defibrillators and cardiac resynchronisation therapy. New transcatheter implantable devices have been developed to improve the treatment of heart failure. There has been a rapid development of minimally invasive or transcatheter devices used in the treatment of heart failure associated with aortic and mitral valve disease and these devices are being incorporated into routine clinical practice at a fast rate...

Thyroid hormones have a significant impact on cardiac function and structure. Excess thyroid hormone affects cardiovascular hemodynamics, leading to high-output heart failure and, in late stages, dilated cardiomyopathy. In this review, we discuss how hyperthyroidism affects cardiovascular pathophysiology and molecular mechanisms and examine the complications caused by excess thyroid hormone, such as heart failure and atrial fibrillation.

Increasing evidence proved that obstructive sleep apnea (OSA) is associated with a variety of diseases, especially cardiovascular diseases. This study systematically reviewed the existing publications to assess the influence of OSA on cardiovascular survival among patients who underwent percutaneous coronary intervention. Eleven eligible publications, including 3,008 participants, were finally evaluated. Eight studies conducted adjustment of risk ratio for potential cardiovascular risk factors, 5 studies defined OSA groups as AHI (apnea hypopnea index) ≥15/hour, whereas the remaining eligible studies used AHI ≥5/hour, AHI ≥10/hour, or AHI ≥30/hour as the criteria...

If the heart is represented by a hydraulic pump, cardiac power represents the hydraulic function of the heart. Cardiac pump function is frequently determined through left ventricular ejection fraction using imaging. This study aims to validate resting cardiac power output (CPO) as a predictive biomarker in patients with advanced heart failure (HF). One hundred and seventy-two patients with HF severe enough to warrant cardiac transplantation were retrospectively reviewed at a single tertiary care institution between September 2010 and July 2013...

: Chronic heart failure is a common clinical condition characterized by persistent excessive sympathetic nervous system activation. The derangement of the sympathetic activity has relevant implications for disease progression and patient survival. Aiming to positively impact patient outcome, autonomic nervous system modulatory therapies have been developed and tested in animal and clinical studies. As a general gross assumption, direct vagal stimulation and baroreflex activation are considered equivalent. This assumption does not take into account the fact that direct cervical vagal nerve stimulation involves activation of both afferent and efferent fibers innervating not only the heart, but the entire visceral system, leading to undesired responses to and from this compartment...

Air pollution is composed of particulate matter (PM) and gaseous pollutants, such as nitrogen dioxide and ozone. PM is classified according to size into coarse particles (PM10), fine particles (PM2.5) and ultrafine particles. We aim to provide an original review of the scientific evidence from epidemiological and experimental studies examining the cardiovascular effects of outdoor air pollution. Pooled epidemiological studies reported that a 10μg/m(3) increase in long-term exposure to PM2.5 was associated with an 11% increase in cardiovascular mortality...

Despite major advances, ischemic cardiomyopathy (ICM) remains a significant cause of death and disability worldwide, with coronary artery disease (CAD) the leading cause of left ventricular (LV) systolic dysfunction. Coronary revascularization may improve LV function, heart failure symptoms and cardiovascular outcomes in high-risk patients with myocardial viability. Multiple imaging modalities have been utilized to detect viable myocardium and predict functional recovery following revascularization. Dobutamine stress echocardiography (DSE), nuclear imaging and cardiac MRI (CMR) are frequently used to assess viability...

Pneumonia is an inflammatory disease of the lung, responsible for high morbidity and mortality worldwide. It is caused by bacteria, viruses, fungi, or other microorganisms. Streptococcus pneumoniae, a gram-positive bacterium with over 90 serotypes, is the most common causative agent. Moreover, comorbid factors including heart failure, renal disease, and pulmonary disease could increase the risk of pneumococcal pneumonia. Since the advent of the pneumococcal vaccine in the 1980s, the incidence of pneumonia has decreased significantly...

Atrial fibrillation (AF) is the most common sustained arrhythmia and across the developed nations, it contributes to increasing hospitalizations and healthcare burden. Several comorbidities and risk factors including hypertension, heart failure, obstructive sleep apnoea and obesity are known to play an important role in the initiation and perpetuation of AF and atrial stretch or dilatation may play a central mechanistic role. The impact of atrial stretch in the development of AF can vary dependent on the underlying disease...

The use of mechanical circulatory support has become an increasingly common practice in patients with heart failure, whether used as bridge to transplantation or as destination therapy. The last couple of decades has seen a drastic change in the functioning of the left ventricular assist devices (LVAD), changing from the first generation devices running on pulsatile flow to the current continuous flow devices. Atrial and ventricular arrhythmias are common among heart failure patients, and though the systematic circulation is well supported in patients on mechanical circulatory support, these arrhythmias can still be the cause of detrimental symptoms and lead to potentially fatal outcomes...
