BACKGROUND: Patients with coronary artery disease who undergo stent implantation and have concomitant indication for long-term oral anticoagulation represent a considerable proportion of the overall population. To date there is still no consensus about the optimal antithrombotic strategy to choose in this kind of patients, due to the difficult balance between an increased risk of bleeding and thromboembolic complications. Therefore, the aim of this study was to perform a meta-analysis to evaluate the risk and benefits of triple antithrombotic therapy versus dual antithrombotic therapy in patients undergoing coronary stent implantation, requiring long-term oral anticoagulation...

INTRODUCTION: Mechanical and morphological ischemia and reperfusion (I/R) injury is reduced in septic hearts. The mechanism behind this "cardioprotection" is less well understood. As adenosine receptors play a major role for cardioprotection in non-septic hearts, we investigated the influence of adenosine receptors in a model of I/R in septic hearts. METHODS: SHAM operation or cecal ligation and puncture (CLP) was performed in adult male Wistar rats (n = 60)...

Adiponectin is the most abundant adipokine and exhibits anti-inflammatory, antiatherogenic and antidiabetic properties. Unlike other adipokines, it inversely correlates with body weight and obesity-linked cardiovascular complications. Diastolic dysfunction is the main mechanism responsible for approximately half of all heart failure cases, the so-called heart failure with preserved ejection fraction (HFpEF), but therapeutic strategies specifically directed towards these patients are still lacking. In the last years, a link between adiponectin and diastolic dysfunction has been suggested...

PURPOSE: Dysfunctional mitochondria are considered to be the major source of intracellular reactive oxygen species and play a central role in the pathophysiology of myocardial ischemia/reperfusion. This study sought to determine effects of mitochondria-targeted cytoprotective peptide SBT-20 on myocardial infarct size in two different models of ischemia/reperfusion. METHODS: For in vivo studies, anesthetized Sprague Dawley rats were subjected to 30 min of coronary artery occlusion followed by 3 h of reperfusion...

The size of the myocardial infarction remains an important therapeutic target, because heart attack size correlates with mortality and heart failure. In this era, myocardial infarct size is reduced primarily by timely reperfusion of the infarct related coronary artery. Whereas numerous pre-clinical studies have shown that certain pharmacologic agents and therapeutic maneuvers reduce myocardial infarction size greater than reperfusion alone, very few of these therapies have translated to successful clinical trials or standard clinical use...

PURPOSE: After injection in the bloodstream, a lipid nanoparticle (LDE) resembling low-density lipoprotein (LDL) concentrates in atherosclerotic lesions of cholesterol-fed rabbits. Here, rabbits with atherosclerosis were treated with carmustine, an antiproliferative agent used in cancer chemotherapy, associated to LDE to investigate the effects on the lesions. METHODS: Twenty-seven male New Zealand rabbits were fed a 1 % cholesterol diet for 8 weeks. After 4 weeks nine animals were treated with intravenous saline solution, nine with intravenous LDE alone, and nine with intravenous LDE-carmustine (4 mg/kg, weekly for 4 weeks)...

PURPOSE: The latest resuscitation guidelines recommend the use of amiodarone in adult patients with out-of-hospital cardiac arrest (OHCA) and refractory ventricular fibrillation (VF) to improve the rates of return of spontaneous circulation. However, there is limited evidence to suggest that amiodarone is superior to lidocaine with respect to survival at discharge. The purpose of the present study was to evaluate the hypothesis that amiodarone is superior to lidocaine with regard to the rate of survival to hospital discharge for OHCA patients with VF/pulseless VT (pVT) on hospital arrival...

PURPOSE: Even with statins and other lipid-lowering therapy (LLT), many patients with heterozygous familial hypercholesterolemia (heFH) continue to have elevated low-density lipoprotein cholesterol (LDL-C) levels. ODYSSEY HIGH FH (NCT01617655) assessed the efficacy and safety of alirocumab, a proprotein convertase subtilisin/kexin type 9 monoclonal antibody, versus placebo in patients with heFH and LDL-C ≥ 160 mg/dl despite maximally tolerated statin ± other LLT. METHODS: Patients were randomized to subcutaneous alirocumab 150 mg or placebo every 2 weeks (Q2W) for 78 weeks...

PURPOSE: Chronically elevated catecholamine levels activate cardiac β-adrenergic receptors, which play a vital role in the pathogenesis of heart failure. Evidence suggests that vasostatin-1 (VS-1) exerts anti-adrenergic effects on isolated and perfused hearts in vitro. Whether VS-1 ameliorates hypertrophy/remodeling by inducing the chronic activation of β-adrenergic receptors is unknown. The present study aims to test the efficacy of using VS-1 to treat the advanced hypertrophy/remodeling that result from chronic β-adrenergic receptor activation and to determine the cellular and molecular mechanisms that underlie this response...

Contrast-induced acute kidney injury (CI-AKI) is a common complication of intravascular administration of contrast media used in coronary angiography, percutaneous coronary intervention and other diagnostic and interventional procedures. This review article aims at summarizing the published literature regarding the prevention of CI-AKI, by focusing on available high-quality meta-analyses addressing this matter. Apart from adequate hydration, a number of pharmacologic agents have been proposed as potential candidates to be included in the routine preparation, prior to the patient's arrival in the cardiac catheterization laboratory...

The role of insulin in the treatment of acute coronary syndrome (ACS) has been widely studied over the past 100 years. The current indication for its use in this context is the treatment of hyperglycemia, irrespective of diabetes, which is associated with adverse outcome. Initial theories proposed that glucose was beneficial in the context of myocardial ischemia and insulin was required to enable glucose cell uptake. However, studies testing this hypothesis with routine insulin administration during ACS have produced disappointing results and research interest has therefore declined...

Guidelines provide recommendations to improve patient outcomes, but many of the recommendations made for treating patients with stable angina are opinion based rather than evidence based. Risk stratification to predict patients at an increased risk of myocardial infarction (MI) and sudden ischemic death, and selection of patients for possible revascularization, is based on expert opinion. Randomized trials have compared optimal medical therapy to revascularization, after the coronary anatomy was known, and yet routine coronary angiography to exclude left main disease is not recommended...

Beta-blockers and calcium channel blockers (CCB) are milestones in the treatment of stable coronary ischaemic disease. Their main effects are particularly suited for the management of effort-induced angina because of the reduction of oxygen demand they achieve. The clinical benefits of these drugs are highly reproducible and have been shown to improve overall clinical outcomes. Despite the availability of other, and newer antianginal drugs, treatment guidelines continue to recommend the use of beta-blockers and calcium channel blockers as first line therapies...

Despite continuous advances in myocardial revascularization procedures and intracoronary devices, patients with ischemic heart disease (IHD) still experience worse prognosis and poor quality of life (QoL). Indeed, chronic stable angina (CSA) is a common disease with a large burden on healthcare costs. Traditionally, CSA is interpreted as episodes of reversible myocardial ischemia related to the presence of stable coronary artery plaque causing myocardial demand/supply mismatch when myocardial oxygen consumption increases...

Stable angina pectoris affects 2-4 % of the population in Western countries and entails an annual risk of death and nonfatal myocardial infarction of 1-2 % and 3 %, respectively. Heart rate (HR) is linearly related to myocardial oxygen consumption and coronary blood flow, both at rest and during stress. HR reduction is a key target for the prevention of ischemia/angina and is an important mechanism of action of drugs which are recommended as first line therapy for the treatment of angina in clinical guidelines...

Percutaneous coronary intervention and anti-anginal medications have similar prognostic effectiveness in patients with chronic stable angina. The choice of optimal medical therapy for the management of chronic angina is of pivotal importance in patients with stable ischemic heart disease. The most commonly used anti-anginal agents have demonstrated equivalent efficacy in improving patient reported ischemic symptoms and quantitative exercise parameters. With regards to mortality, beta-blockers are beneficial only in the setting of depressed left ventricular systolic function after a recent myocardial infarction...
