Basic fibroblast growth factor (bFGF), a known angiogenic factor, may provide a potential strategy for the treatment of myocardial infarction (MI), but it is limited by a relatively short half-life. Dex-PCL-HEMA/PNIPAAm hydrogel provides a reservoir for the controlled release of growth factors. The aim of the current study was to evaluate the effects of bFGF incorporated into a Dex-PCL-HEMA/PNIPAAm hydrogel on angiogenesis and cardiac health in a rat model of acute MI, induced by coronary artery ligation. Phosphate-buffered solution (PBS group), Dex-PCL-HEMA/PNIPAAm hydrogel (Gel group), bFGF in phosphate-buffered solution (bFGF group) or bFGF in hydrogel (Gel + bFGF group) was injected into a peri-infarcted area of cardiac tissue immediately following MI...

BACKGROUND AND AIMS: Increased proinsulin relative to insulin levels have been associated with subclinical atherosclerosis (measured by carotid intima-media thickness (cIMT)) and are predictive of future cardiovascular disease (CVD), independently of established risk factors. The mechanisms linking proinsulin to atherosclerosis and CVD are unclear. A genome-wide meta-analysis has identified nine loci associated with circulating proinsulin levels. Using proinsulin-associated SNPs, we set out to use a Mendelian randomisation approach to test the hypothesis that proinsulin plays a causal role in subclinical vascular remodelling...

Cardiac fat tissue volume and vascular dysfunction are strongly associated, accounting for overall body mass. Despite its pathophysiological significance, the origin and autocrine/paracrine pathways that regulate cardiac fat tissue and vascular network formation are unclear. We hypothesize that adipocytes and vasculogenic cells in adult mice hearts may share a common cardiac cells that could transform into adipocytes or vascular lineages, depending on the paracrine and autocrine stimuli. In this study utilizing transgenic mice overexpressing prokineticin receptor (PKR1) in cardiomyocytes, and tcf21ERT-cre(TM)-derived cardiac fibroblast progenitor (CFP)-specific PKR1 knockout mice (PKR1 (tcf-/-)), as well as FACS-isolated CFPs, we showed that adipogenesis and vasculogenesis share a common CFPs originating from the tcf21(+) epithelial lineage...

BACKGROUND: Hemodynamic balance in the heart-brain axis is increasingly recognized as a crucial factor in maintaining functional and structural integrity of the brain and thereby cognitive functioning. Patients with heart failure (HF), carotid occlusive disease (COD), and vascular cognitive impairment (VCI) present themselves with complaints attributed to specific parts of the heart-brain axis, but hemodynamic changes often go beyond the part of the axis for which they primarily seek medical advice...

Cannabis is one of the most commonly used illicit drugs in the United States and is considered to have several adverse health effects. There is evidence suggesting that its recreational use is associated with both increased cardio- and cerebrovascular events. Recently, multiple cases of ischemic and hemorrhagic strokes associated with cannabis use were reported in the literature (Goyal et al., 2017). It has been suggested that cannabis can affect cerebral auto-regulation and vascular tone leading to vasoconstriction and acute ischemic stroke...

During the last decade, life expectancy increased in western countries. Among the elderly, cardiovascular diseases are still the leading cause of death. In both genders, cardiovascular risk increases with age. The statistical correlation between total cholesterol level and mortality is less substantial with age, yet it still exists. Clinical studies have shown the clinical benefit of statin therapy, both in terms of cardio-vascular events and survival in the elderly population. The use of statins in elderly patients can currently be recommended for secondary prevention...

BACKGROUND: Nicorandil leads to the relaxation of fine vascular smooth muscle, and thus causes vasodilatation of major epicardial. Also, it has anti-arrhythmic and cardio-protective effects by improving reperfusion, and ultimately leads to a reduction in microvascular damage caused by percutaneous coronary intervention (PCI). OBJECTIVE: The aim of this study was to determine the effect of nicorandil on QT interval dispersion (QTd) in patients with stable angina pectoris during elective angioplasty...

REVIEW
Ugo Teatini, Giorgio Romei Longhena
Uremic status results from a malfunctioning of kidneys due to the accumulation of compounds which, under normal conditions, are excreted or metabolized by the kidneys. If these compounds are biologically active, they are called uremic toxins. Such compounds have toxic effects on the cardio-vascular system. An useful classification, published by the European Uremic Toxin Work Group (EUTox) is: 1) small water-soluble compounds; 2) protein-bound compounds; 3) the larger "middle molecules". High-flux membranes and more efficient treatment techniques, like HDF, improve the removal of uremic toxins in the middle molecular-weight range, and recent studies suggest that these strategies have better results on the morbidity and mortality...

BACKGROUND: Pulmonary hypertension (PH) is an important lethal manifestation of systemic sclerosis (SSc). Evidence of an association between peripheral and pulmonary arterial vasculopathy in SSc has been demonstrated. We hypothesized that peripheral arterial stiffness could predict PH in SSc. METHODS: We performed a cross-sectional study among patients with SSc who underwent Cardio-Ankle Vascular Index (CAVI, VaSera VS-1000; Fukuda Denshi, Tokyo, Japan) and transthoracic echocardiography (TTE) examination to evaluate peripheral arterial stiffness and PH, respectively...

The cardio-ankle vascular index (CAVI) is a measure of global arterial stiffness. We hypothesized that CAVI is associated with left ventricular (LV) function and geometry in individuals without structural heart disease. We measured CAVI in 600 participants (mean age 60.3±14.6 years, 54% men) without history of atherosclerotic cardiovascular disease who were referred for transthoracic echocardiography. Linear regression analysis was used to assess the association of CAVI with LV function (peak mitral annular systolic s' and early diastolic velocity e') and structure (LV mass index (LVMI) and relative wall thickness (RWT))...

BACKGROUND: Cardiovascular disease is the major cause of death in patients with chronic kidney disease, even after renal transplantation. Cardio-ankle vascular index (CAVI) provides an indicator of arterial stiffness, whereas fibroblast growth factor-21 (FGF-21) levels may provide a biomarker for atherosclerotic disease. We investigated the association between CAVI and FGF-21 and their relationships to carotid intima-media thickness (IMT) and other cardiovascular risk factors. METHODS: This study included 90 renal transplant patients...

Rationale The pathophysiology of most lacunar stroke, a form of small vessel disease, is thought to differ from large artery atherothrombo- or cardio-embolic stroke. Licensed drugs, isosorbide mononitrate and cilostazol, have promising mechanisms of action to support their testing to prevent stroke recurrence, cognitive impairment, or radiological progression after lacunar stroke. Aim LACI-1 will assess the tolerability, safety, and efficacy, by dose, of isosorbide mononitrate and cilostazol, alone and in combination, in patients with ischemic lacunar stroke...
