Efficacy and Safety of Adjunctive Cilostazol to Clopidogrel-Treated Diabetic Patients With Symptomatic Lower Extremity Artery Disease in the Prevention of Ischemic Vascular Events.

Background Type 2 diabetes mellitus is a risk factor for lower extremity arterial disease. Cilostazol expresses antiplatelet, anti-inflammatory, and vasodilator actions and improves the claudication intermittent symptoms. We investigated the efficacy and safety of adjunctive cilostazol to clopidogrel-treated patients with type 2 diabetes mellitus exhibiting symptomatic lower extremity arterial disease, in the prevention of ischemic vascular events and improvement of the claudication intermittent symptoms.

Painful left bundle branch block: A syndrome with a particular clinical significance.

The development of angina in the setting of new-onset left bundle branch block (LBBB) that resolves at the same time with the disappearance of LBBB, without coexistent myocardial ischemia, denotes the painful LBBB syndrome. In this illustrative case report we describe a young male patient with painful LBBB syndrome. The LBBB was rate-dependent occurring during exercise and the patient was successfully treated with bisoprolol.

Cardiovascular disease in women: Executive summary of the expert panel statement of women in cardiology of the hellenic cardiological society.

The perception that women represent a low-risk population for cardiovascular (CV) disease (CVD) needs to be reconsidered. Starting from risk factors, women are more likely to be susceptible to unhealthy behaviors and risk factors that have different impact on CV morbidity and mortality as compared to men. Despite the large body of evidence as regards the effect of lifestyle factors on the CVD onset, the gender-specific effect of traditional and non-traditional risk factors on the prognosis of patients with already established CVD has not been well investigated and understood.

The incidence of recurrent cardiovascular events among acute coronary syndrome patients treated with generic or original clopidogrel in relation to their sociodemographic and clinical characteristics. The Aegean study.

Introduction: The use of generic drugs is continuously growing; however, there are limited epidemiological data regarding the therapeutic equivalence of each original drug formulation with its generic counterparts. We evaluated the 12-month composite endpoint of recurrent acute myocardial infarction, ischaemic stroke, cardiac deaths, or hospitalisation due to a major bleeding in acute coronary syndrome (ACS) patients treated with original clopidogrel or a generic clopidogrel formulation, in relation to sociodemographic and clinical characteristics.

Material And Methods: Consecutive Greek ACS patients ( = 1194) hospitalised in the Aegean islands and the Attica region were enrolled.

Comparison of Triflusal with Aspirin in the Secondary Prevention of Atherothrombotic Events; Α Randomised Clinical Trial.

Antiplatelet treatment in the secondary prevention of coronary and cerebrovascular disease: is there any place for novel agents?

Ischemic heart disease and cerebrovascular disease remain major health problems with associated mortality and quality-of-life consequences. Antiplatelet agents, including thienopyridines and the new P2Y12 inhibitors, have been shown to improve survival in the secondary prevention setting. We review the available evidence on the effectiveness and safety of previous established as well as novel antithrombotic agents in the secondary prevention of cardiovascular disease with a special focus on cerebrovascular disease.

Ibutilide and novel indexes of ventricular repolarization in persistent atrial fibrillation patients.

Aim: To examine the effect of ibutilide on novel indexes of repolarization in patients with persistent atrial fibrillation (AF).

Methods: We studied consecutive patients scheduled for elective electrical cardioversion. Intravenous ibutilide (1 + 1 mg) was administered before the electrical cardioversion while close electrocardiographic (ECG) monitoring was performed.

Clopidogrel generic formulations in the era of new antiplatelets: a systematic review.

Clopidogrel is a thienopyridine that selectively and irreversibly inhibits the ADP purinergic receptor P2Y12 and the subsequent ADP-mediated platelet activation. Clopidogrel has been approved for clinical use as clopidogrel hydrogen sulfate (bisulfate) salt. The clinical usefulness of clopidogrel bisulfate salt has been proved in a wide variety of large scale clinical trials, thus clopidogrel bisulfate has been extensively used in a large spectrum of patients been under thrombotic risk.

The impact of hemodialysis on the dispersion of ventricular repolarization.

Background: Sudden cardiac death is prevalent in chronic hemodialysis (HD) patients while the dialysis process may have arrhythmogenic potential. We sought to examine the effect of HD on conventional electrocardiographic parameters as well as on novel indexes of repolarization, given that increased spatial dispersion of repolarization is related to ventricular arrhythmias.

Methods: We recorded clinical, echocardiographic, and laboratory parameters as well as electrocardiographic indexes before and after a single HD session.

The mediating effect of the Mediterranean diet on the role of discretionary and hidden salt intake regarding non-fatal acute coronary syndrome or stroke events: case/case-control study.

Objectives: The aim of the present work was to evaluate the association between salt and salty food consumption on the development of an acute coronary syndrome (ACS) or ischemic stroke, under the context of adherence to the Mediterranean diet.

Methods: During 2009-2010, 1000 participants were enrolled; 250 were consecutive patients with a first ACS, 250 were consecutive patients with a first ischemic stroke and 500 population-based, control subjects, one-for-one matched to the patients by age and sex. Socio-demographic, clinical, psychological, dietary and other lifestyle characteristics were measured.

Pharmacodynamic properties of antiplatelet agents: current knowledge and future perspectives.

Platelets play an important role in atherothrombotic disease. The currently available antiplatelet drugs target key steps of platelet activation including thromboxane A(2) synthesis, ADP-mediated signaling, and glycoprotein IIb/IIIa-mediated platelet aggregation. The improvement of our understanding on the pharmacokinetic and pharmacodynamic characteristics of these drugs enables the tailoring of the most appropriate anti-thrombotic therapy to the individual patient and risk situation in the daily clinical practice.

Leukocyte labile iron pool in patients with systolic heart failure.

Introduction: Data regarding sources of oxidative stress in the failing myocardium are sparse. Leukocytes actively participate in the oxidative damage observed in human heart failure (HF). The intracellular labile iron pool (LIP) represents a source of toxic reactive oxygen species.

Platelet-mediated inflammation in cardiovascular disease. Potential role of platelet-endothelium interactions.

Inflammation of the vascular wall is considered as the principal underlying mechanism in the development of atherosclerosis. Besides their specific functions in haemostasis via thrombus formation after an endothelial injury, a growing body of evidence indicates that platelets play an important role in the inflammatory reactions occurring in the vascular wall as well as in the subsequent tissue repair mechanisms. Platelets interact with activated endothelium as well as with circulating leukocytes and progenitor cells.

Effect of clopidogrel besylate on platelet reactivity in patients with acute coronary syndromes. Comparison with clopidogrel hydrogen sulfate.

Objective: The efficacy of clopidogrel therapy in patients with an acute coronary syndrome (ACS) has been established using the clopidogrel hydrogen sulfate (CHS) formulation. In this study we compared the antiplatelet effectiveness of a generic clopidogrel salt, clopidogrel besylate (CB), with the original CHS in patients with an ACS.

Research Design And Methods: Ninety-six ACS patients were randomized to receive a 600-mg loading dose of either CHS (n = 45) or CB (n = 51), followed by 75 mg/day.

Antiplatelet efficacy of long-term treatment with clopidogrel besylate in patients with a history of acute coronary syndrome: comparison with clopidogrel hydrogen sulfate.

The efficacy of clopidogrel therapy in patients with an acute coronary syndrome (ACS) has been established using the clopidogrel hydrogen sulfate (CHS) formulation. We compared the antiplatelet effectiveness of long-term administration of the original CHS with a generic clopidogrel besylate (CB) salt formulation in 86 patients with a history of an ACS. At 1 month after the episode, patients receiving 75 mg/d CHS were randomized to continue with CHS (n = 41) or to switch to 75 mg/d CB (n = 45).

Influence of high-density lipoprotein and paraoxonase-1 on platelet reactivity in patients with acute coronary syndromes receiving clopidogrel therapy.

Background: The paraoxonase activity of the enzyme paraoxonase-1 (PON-1) associated with high-density lipoprotein (HDL) may significantly influence clopidogrel's antiplatelet and clinical efficacy as a result of its involvement in the clopidogrel biotransformation to the pharmacologically active thiol metabolite. We evaluated the possible relationships of HDL levels as well as PON-1 activities and the Q192R genotype with clopidogrel's antiplatelet efficacy in acute coronary syndrome (ACS) patients.

Methods And Results: The platelet aggregation, P-selectin expression and platelet/leukocyte conjugates as well as the clopidogrel response variability (evaluated by the VASP phosphorylation test and expressed as platelet reactivity index, PRI) were assessed in 74 ACS patients undergoing percutaneous coronary intervention (PCI) in relation to the PON-1 Q192R genotype and to serum HDL-cholesterol levels, and PON-1 (paraoxonase and arylesterase) activities.

Adherence to the Mediterranean diet in relation to acute coronary syndrome or stroke nonfatal events: a comparative analysis of a case/case-control study.

Background: Although the role of Mediterranean diet on cardiovascular disease prevention has long been evaluated and understood, its association with the development of stroke has been rarely examined. The aim of the present work was to comparatively evaluate the association between adherence to the Mediterranean diet and the development of an acute coronary syndrome (ACS) or ischemic stroke.

Methods: During the period from 2009 to 2010, 1,000 participants were enrolled; 250 were consecutive patients with a first ACS, 250 were consecutive patients with a first ischemic stroke, and 500 population-based, control subjects, 1-for-1 matched to the patients by age and sex.

Gender effects on novel indexes of heterogeneity of repolarization in patients with stable coronary artery disease.

Introduction: There appear to be important gender differences with respect to the incidence and clinical course of arrhythmias. It has been shown that women with coronary artery disease (CAD) have a lower rate of ventricular arrhythmias and sudden cardiac death (SCD) than men. The T peak-to-end (Tpe) interval and the Tpe/QT ratio represent novel markers of arrhythmic risk that possibly correspond to the spatial dispersion of ventricular repolarization.
