BACKGROUND: Heart failure with reduced ejection fraction caused by ischemic heart disease is associated with increased morbidity and mortality. It remains unclear whether revascularization by either coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) carries benefits or risks in this group of stable patients compared with medical treatment. METHODS AND RESULTS: We performed a meta-analysis of available studies comparing different methods of revascularization (PCI or CABG) against each other or medical treatment in patients with coronary artery disease and left ventricular ejection fraction ≤40%...

30% of the world population is diagnosed with metabolic syndrome. High fat/high sucrose diet (HF/HS, Western diet) correlates with metabolic syndrome prevalence. We characterized effects of the HF/HS diet on vascular (arterial stiffness, vasoreactivity, coronary collateral development) and cardiac (echocardiography) function, oxidative stress and inflammation in a rat model of metabolic syndrome (JCR). Furthermore, we determined whether male vs. female animals were affected differentially by the Western diet...

BACKGROUND: Ultrasound exam as a screening test for abdominal aorta (AA) can visualize the aorta in 99% of patients and has a sensitivity and specificity approaching 100% in screening settings for aortic aneurysm. Pocket Size Imaging Device (PSID) has a potential value as a screening tool, because of its possible use in several clinical settings. Our aim was to assess the impact of demographics and cardiovascular (CV) risk factors on AA size by using PSID in an outpatient screening. METHODS: Consecutive patients, referring for a CV assessment in a 6 months period, were screened...

The recreational use of illicit drugs remains an enormous and growing problem throughout the United States of America and around the world. Cocaine is most frequently thought of when considering the cardiovascular toxicity of illicit drugs. The association of cocaine use with sudden death due to myocardial ischaemia and infarction is well recognised, and this risk appears to be amplified by concomitant cigarette smoking and alcohol consumption. Like cocaine, amphetamine and its derivatives lead to indirect stimulation of the autonomic nervous system through the release of norepinephrine, dopamine, and serotonin in nerve terminals of the central and autonomic nervous systems...

Sudden unexpected cardiac deaths in approximately 20% of young athletes are due to acquired or congenital coronary artery abnormalities. Kawasaki disease is the leading cause for acquired coronary artery abnormalities, which can cause late coronary artery sequelae including aneurysms, stenosis, and thrombosis, leading to myocardial ischaemia and ventricular fibrillation. Patients with anomalous left coronary artery from the pulmonary artery can develop adequate collateral circulation from the right coronary artery in the newborn period, which remains asymptomatic only to manifest in adulthood with myocardial ischaemia, ventricular arrhythmias, and sudden death...

Objectives Pulmonary dysfunction is a recognized postoperative complication that may be linked to use of cardiopulmonary bypass. The off-pump technique of coronary artery bypass aims to avoid some of the complications that may be related to cardiopulmonary bypass. In this study, we compared the influence of on-pump or off-pump coronary artery bypass on pulmonary gas exchange following routine surgery. Methods Fifty patients (mean age 60.4 ± 8.4 years) with no preexisting lung disease and good left ventricular function undergoing primary coronary artery bypass grafting were prospectively randomized to undergo surgery with or without cardiopulmonary bypass...

BACKGROUND: As life expectancy increases, more elderly patients with end-stage hip arthritis are electing to undergo primary THA. Octogenarians undergoing THA have more comorbidities than younger patients, but this is not reflected in risk adjustment models for bundled care programs. The burden of care associated with THA in octogenarians has not been well characterized, and doing so may help these value-based programs make adjustments so that this vulnerable patient population does not risk losing access under accountable care models...

Acute alcohol intoxication is a common cause of emergency visits worldwide. Although moderate alcohol consumption is protective against coronary artery disease, binge drinking is associated with adverse cardiovascular and neurological outcomes and may even cause sudden death. Although, few past accounts of venous thrombosis with alcohol binge drinking are available, arterial thrombosis with the condition has never been reported in the literature. We present the unusual case of a young Afghan male, who presented to us with painful, tender and swollen legs three days after a heavy alcohol binge on a Saturday night...

BACKGROUND: Non-obstructive coronary artery disease (CAD) identified by coronary computed tomography angiography (CCTA) demonstrated prognostic value. CT-adapted Leaman score (CT-LeSc) showed to improve the prognostic stratification. Aim of the study was to evaluate the capability of CT-LeSc to assess long-term prognosis of patients with non-obstructive (CAD). METHODS: From 17 centers, we enrolled 2402 patients without prior CAD history who underwent CCTA that showed non-obstructive CAD and provided complete information on plaque composition...

INTRODUCTION: Current Appropriatene Usa Criteria exclude coronary computed tomography angiography (CTA) in asymptomatic individuals. We compared the prognostic value of coronary CTA in asymptomatic individuals to symptomatic patients with "definitely appropriate" indications for coronary CTA. METHODS: Consecutive patients without previously known CAD referred for a CTA exam were divided into 2 groups. One group consisted ofasymptomatic individuals, the other of symptomatic patients with a "definitely appropriate" indication for coronary CT (unable to exercise and/or with an uninterpretable electrocardiogram and at an intermediate pre-test probability of obstructive coronary artery disease)...

BACKGROUND: The delayed Gadolinium Myocardium Enhancement (DGE) extent on Cardiac Magnetic Resonance (CMR) correlates with biomarkers of myocardial injury in patients with acute viral myocarditis and is an independent predictor of adverse cardiovascular outcome. Ventriculoarterial Coupling (VAC) is related to both the cardiovascular work output and energy efficiency and can be noninvasively assessed. In this work, we aimed to evaluate alterations in VAC indices in correlation with DGE in patients with acute myocarditis...

Kawasaki disease is a febrile disease of childhood that is associated with increased inflammatory cytokines and immunoregulatory abnormalities. While the serum concentrations of soluble IL-2 receptor can change under such pathologies, the relevance of the soluble IL-2 receptor concentration in patients with Kawasaki disease has not been specified. We aimed to summarize the existing studies that reported the soluble IL-2 receptor concentrations in patients with Kawasaki disease. Original articles that were published up to July 2016 were collected using a PubMed/Medline-based search engine...
