INTRODUCTION: Patients undergoing coronary catheterization are at high risk of developing contrast-induced nephropathy (CIN) acute kidney injury (AKI). Several approaches have been supposed to limit such an effect but with mixed results or non-practical methods. Spironolactone is supposed to be effective as a nephroprotective agent in animal studies. This study will try to measure the effect of spironolactone on the incidence of CIN-AKI in patients undergoing coronary catheterization (angiography angioplasty)...

INTRODUCTION: Trimetazidine (TMZ) is an anti-ischemic metabolic agent that has been shown to be efficacious in angina treatment, both in monotherapy and in combination. A new formulation of TMZ modified-release (MR) 80 mg was developed, which is to be taken once daily (od), instead of twice daily (bid) for the currently available TMZ MR 35 mg, with the aim of simplifying the medication regimen. METHODS: The present study was an international, multicenter, randomized, double-blind, parallel-group phase III study with a 12-week treatment period...

INTRODUCTION: Optimal antithrombotic therapy after transcatheter aortic valve replacement (TAVR) remains unclear. We evaluated the association between antithrombotic regimens and outcomes in TAVR patients. METHODS: We retrospectively analyzed consecutive patients who underwent TAVR at a single academic center from April 2009 to March 2014. Antithrombotic regimens were classified as single or dual antiplatelet therapy (AP), single antiplatelet plus anticoagulant (SAC), or triple therapy (TT)...

Right ventricular (RV) myxomas are extremely rare, but may have dreadful clinical sequelae including pulmonary embolism (PE). We present a case of a patient who had an RV myxoma that was attached to the tricuspid valve, and therefore could not be resected completely during surgery, and remnants of the tumor were seen on transthoracic echocardiogram during post-operative follow-up. Five months after surgery, the patient had PE, which could be due to tumor emboli or thromboemboli. Since repeat surgical resection was not feasible, the patient was started on warfarin...

INTRODUCTION: For patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI), proper antithrombotic therapy is equivocal. Current guidelines recommend triple therapy, which carries a high risk of bleeding. Recent large trials suggest that dual therapy (DT) with novel oral anticoagulant (NOAC) plus P2Y12 inhibitor can be an appropriate alternative, but real-world data for this alternative are scarce and the optimal duration of DT has not yet been established...

Venous thromboembolism (VTE), which includes both deep vein thrombosis and pulmonary embolism (PE), is a very common disorder with high risk for recurrence and is associated with significant morbidity and mortality. The non-vitamin K oral anticoagulants (NOACs), which include dabigatran, rivaroxaban, apixaban, and edoxaban, have been shown to be noninferior to conventional anticoagulant therapy for the prevention of recurrent VTE and are associated with more favorable bleeding risk. Evidence from the treatment of VTE with traditional therapy (low molecular weight heparin and vitamin K antagonists) implies that extended or indefinite treatment reduces risk of recurrence...

Atrial fibrillation (AF) is an established risk factor for a first or recurrent stroke. Despite proven efficacy in preventing stroke in patients with AF, warfarin is underused, partly due to safety concerns. Recent randomized trials have shown that non-vitamin K antagonist oral anticoagulants (NOACs) such as dabigatran (a direct thrombin inhibitor) and apixaban, edoxaban, and rivaroxaban (factor Xa inhibitors) are not only non-inferior or superior to warfarin but also demonstrate a decreased risk of cerebrovascular bleeding among patients with AF and moderate to high risk of stroke...

Cardiovascular diseases are the leading cause of death worldwide. Research in the last two decades has emphasized the inflammatory process as a key component in the pathogenesis of many of them. The Interleukin-1 family is a pivotal element of inflammation and has been well studied as a therapeutic target in various inflammatory states. Recent trials have explored the effect of Interleukin-1 blockade in cardiovascular diseases and initial evidence of the relevance of such treatment in this field of medicine accumulate...

The recreational use of cannabis has sharply increased in recent years in parallel with its legalization and decriminalization in several countries. Commonly, the traditional cannabis has been replaced by potent synthetic cannabinoids and cannabimimetics in various forms. Despite overwhelming public perception of the safety of these substances, an increasing number of serious cardiovascular adverse events have been reported in temporal relation to recreational cannabis use. These have included sudden cardiac death, vascular (coronary, cerebral and peripheral) events, arrhythmias and stress cardiomyopathy among others...

Transcatheter aortic valve replacement (TAVR) has become standard therapy for patients with severe aortic stenosis who are deemed at least intermediate risk for surgical valve replacement. Over the past decade, several technological advances have taken place to improve the quality and safety of these devices. The current commercially available valves are broadly grouped into balloon expandable and self-expandable valves. The latest iteration of the self-expandable valve is Medtronic's repositionable valve known as the Evolut PRO system...

Coronary artery bypass grafting (CABG) remains a vital treatment for patients with multivessel coronary artery disease (CAD), especially diabetics. The long-term benefit of the internal thoracic artery graft is well established and remains the gold standard for revascularization of severe CAD. It is not always possible to achieve complete revascularization through arterial grafts, necessitating the use of saphenous vein grafts (SVG). Unfortunately, SVGs do not have the same longevity, and their failure is associated with significant adverse cardiac outcomes and mortality...

Stroke is the second leading cause of death worldwide and in Europe. Even with gold standard medical management of acute ischemic stroke, which is intravenous (IV) thrombolysis by administration of recombinant tissue plasminogen activator (rt-PA), the mortality rate remains the same. Intra-arterial (IA) thrombolysis therapy also did not achieve significant results and was not approved by the US Food and Drug Administration (FDA) because of limited sample size. This encouraged scientists and engineers to develop endovascular clot retrieval devices for the mechanical recanalization of the occluded arteries in stroke patients...

Cardiac disease remains a major cause of morbidity and mortality in pregnant and post-partum women, although progress has been made, with specialist joint obstetric-cardiology clinics providing an integrated, safe and personalised service to these women. As a result, fewer non-specialist cardiologists are managing women in pregnancy with cardiovascular disease. The aim of this review is to provide a brief overview of current knowledge and practice in the field, with an emphasis on the major physiological changes which occur during pregnancy, focussing on progress through the trimesters, clinical assessment in pregnancy, management of delivery (concentrating on managed vaginal delivery), drug treatment, key conditions and risk assessment...

INTRODUCTION: Many studies have highlighted the important role of PCSK9 in the development of cardiometabolic changes and its possible function as a biomarker of myocardial infarction or ischemic heart disease. This study aimed to determine the relationship between circulating PCSK9 levels and subclinical vascular changes in the group of low risk patients without manifest cardiovascular diseases. METHODS: In this study, 120 healthy patients, free of manifest cardiovascular diseases, diabetes mellitus, and without lipid-lowering therapy, were divided into three groups based on BMI: normal weight (N = 50), overweight (N = 30), and obese (N = 40)...

INTRODUCTION: Data about treatments and recurrent ischemic events in patients surviving their most recent myocardial infarction event-free for at least 12 months are scarce. METHODS: In a retrospective data analysis, charts of patients who had a myocardial infarction 1-3 years ago with an event-free period of at least 12 months after the index event and at least one high risk factor were centrally collected and analyzed. Here we compare patients with ST elevation myocardial infarction (STEMI) versus non-ST elevation myocardial infarction (NSTEMI)...
