Integrative medicine on optimizing clopidogrel and aspirin therapy
This article reviews the available published data on optimizing clopidogrel and aspirin therapy using translational and integrative medicine. Translational and evidence-based medical studies show that theCYP2C19 gene mutation (CYP2C19*2 andCYP2C19*3) could affect> 50% of the Chinese population, and that this mutation is closely associated with clopidogrel resistance and an increased risk of major adverse cardiovascular events, particularly stent thrombosis in patients following percutaneous coronary intervention (PCI). Adjusted-dose warfarin and aspirin reduce stroke in patients with atrial fibrillation (AF), and warfar...

Antithrombotic Therapy and Outcomes of Patients With New-Onset Transient Atrial Fibrillation After ST-Segment Elevation Myocardial Infarction
Conclusions: There is not a widely accepted treatment algorithm in patients with STEMI who complicated with new-onset AF in clinical guidelines. The current study indicated that transient form of new-onset AF might not require long-term VKA. Besides, addition of VKA to DAPT therapy may increase the rates of major and minor bleeding.

Antithrombotic Treatment after Carotid Stenting in Patients with Concomitant Atrial Fibrillation INTERVENTIONAL
CONCLUSIONS: Among patients with carotid artery stent placement with atrial fibrillation, triple therapy confers a high bleeding risk. A regimen of direct oral anticoagulants plus a P2Y12 inhibitor might confer a good safety profile with significantly lower rates of bleeding and optimal efficacy.

Concomitant use of antiplatelet therapy with dabigatran or warfarin in the randomised evaluation of long-term anticoagulation therapy (RE-LY®) trial: subgroup analysis
Source: Circulation Area: News RE-LY showed that dabigatran etexilate 150 mg bid (DE150) was superior, and 110 mg bid (DE110) non-inferior to warfarin in preventing stroke and systemic embolism (SSE) in patients with atrial fibrillation (AF). A common clinical dilemma regarding treatment of patients with AF is the need to use concomitant antiplatelets for a variety of reasons. While the combination of OAC and antiplatelets carry the potential of additive benefits, they also carry the danger of increased risk of bleeding.   With the emergence of dabigatran, questions on its efficacy and safety in patients receivin...

Novel Oral Anticoagulants and Gastrointestinal Bleeding: a Case for Cardiogastroenterology
With the rapidly evolving cardiology drug pipeline for treatment of acute coronary syndrome (ACS), gastroenterologists have witnessed the emergence of a new population of patients who are vulnerable to gastrointestinal (GI) bleeding: the chronic cardiac patient. ACS, causing myocardial infarction (MI) and unstable angina, and atrial fibrillation are the signature conditions of the chronic cardiac patient. The morbidity and mortality of ACS is significant. Chronic cardiac patients are prescribed complex antithrombotic therapy (CAT) (ie, aspirin [ASA] plus a thienopyridine, eg, clopidogrel [Plavix; Bristol-Myers Squibb/Sanof...

Thromboprophylaxis in heart failure patients with sinus rhythm: aspirin and warfarin lead to similar cardiovascular outcomes
Commentary on: Homma S, Thompson JL, Pullicino PM, et al.. WARCEF Investigators. Warfarin and aspirin in patients with heart failure and sinus rhythm. N Engl J Med 2012;366:1859–69. Context Chronic heart failure (CHF) is common, affecting 1–2% of the population and 10% of people >70 years. Patients with CHF have an increased risk of thromboembolism. Those with atrial fibrillation (AF) should receive warfarin but whether CHF patients with sinus rhythm (SR), whose risk is 1.5–3.5%,1 should receive thromboprophylaxis is unclear. Previous studies, Warfarin/Aspirin Study in Heart failure (warfarin, asp...

Triple Antithrombotic Therapy With Prasugrel in the Stented Patient Concern for More Bleeding ⁎ ⁎
There is a large body of evidence, including results of prospective trials, that supports oral anticoagulation therapy (OAT) as the optimal strategy to prevent fibrin-centric thrombotic events (FCTEs). Examples of FCTEs include thromboembolism in patients with mechanical heart valves, deep vein thrombosis, and atrial fibrillation (AF) (1). In a large prospective trial, warfarin was found to be superior to dual antiplatelet therapy (DAPT) with aspirin + clopidogrel in the prevention of vascular events in patients with AF plus 1 or more risk factors for stroke (2). European and American guidelines include a Class I recommend...

Thrombocytopenia in Patients With Atrial Fibrillation on Oral Anticoagulation Undergoing Percutaneous Coronary Intervention
In conclusion, mild to moderate baseline thrombocytopenia does not seem to have a clinically significant effect on bleeding or thrombotic or thromboembolic complications after PCI in these frail patients receiving multiple antithrombotic drugs.

Antithrombotic Regimens in Patients With Atrial Fibrillation and Coronary Disease Optimizing Efficacy and Safety ∗
Clear evidence supports the value of oral anticoagulation (OAC) with vitamin K antagonists in preventing stroke and thromboembolism in patients with atrial fibrillation (AF) who have well-established risk factors. For this indication, vitamin K antagonists have been shown to be superior to single or dual antiplatelet agents in reducing thromboembolic complications (1). Yet, up to 30% of patients with AF also have indications for antiplatelet therapy because of coronary artery disease (2). Dual antiplatelet therapy with aspirin and a P2Y12 receptor inhibitor (e.g., clopidogrel) is usually recommended after stent implantatio...

Meta-Analysis of Randomized Controlled Trials on Risk of Myocardial Infarction from the Use of Oral Direct Thrombin Inhibitors
In conclusion, our data suggest that oral DTIs were associated with increased risk of MI. This increased risk appears to be a class effect of these agents, not a specific phenomenon unique to dabigatran or protective effect of warfarin. These findings support the need for enhanced postmarket surveillance of oral DTIs and other novel agents.

One‐Year Outcome of Patients With Atrial Fibrillation Undergoing Coronary Artery Stenting: An Analysis of the AFCAS Registry
ConclusionsIn this large, real‐world population of AF patients undergoing PCI‐S, TT was the antithrombotic regimen most frequently prescribed. Although several limitations need to be acknowledged, in our study the 1‐year efficacy and safety of TT, dual antiplatelet therapy, and VKA plus clopidogrel was comparable.

Atrial Fibrillation: Should we Target Platelets or the Coagulation Pathway?
Abstract Based on the established fact that anticoagulation with warfarin is superior to antiplatelet agents in the prevention of thromboembolic events in atrial fibrillation (AF), we propose that, in contrast to atherothrombotic disorders, the risk of developing a stroke or thromboembolic event in AF is more likely to be affected by the coagulation pathway than by platelet activity. Indeed, platelet-rich thrombi may be the predominant underlying pathophysiological process in coronary artery disease patients, thus representing an entirely different prothrombotic profile to the patients with AF, where clotting fac...

0203: Analysis of antithrombotic therapy in patients over 75 years with non-valvular atrial fibrillation: do we apply the guidelines to elderly subjects?
Conclusions A higher rate of anticoagulation is found in this elderly population compared with previous “real life” records. Anticoagulant therapy is however less systematic in paroxysmal AF and women.
