Single direct oral anticoagulant therapy in stable patients with atrial fibrillation beyond 1 year after coronary stent implantation
Conclusions DOAC monotherapy showed similar efficacy in preventing ischaemic events and was associated with lower major bleeding events compared with combination therapy in patients with AF beyond 1 year after coronary stent implantation.

Contemporary management of persistent atrial fibrillation
Learning objectives Develop a basic understanding of the underlying mechanisms of atrial fibrillation and classification of the disease. Review the main principles in contemporary management of atrial fibrillation with a focus on persistent atrial fibrillation. Discuss catheter ablation in the context of atrial fibrillation. Introduction Atrial fibrillation (AF) is a multisystemic disorder that is associated with an excess risk of stroke, heart failure and mortality.1 It remains the most common sustained arrhythmia and its significance should not be underestimated. Research focused on unveiling the mechanisms of AF began o...

Response to: Correspondence on "Association between cardiologist evaluation and mortality in myocardial injury after non-cardiac surgery" by Müller et al
The Authors’ reply: In response to valuable comments by Müller et al,1 we are pleased to share results of additional analysis on our recent study ‘Association between cardiologist evaluation and mortality in myocardial injury after non-cardiac surgery’.2 We hope the additional information would be helpful for readers. First, we agree with the concern and conducted analysis on 2322 myocardial injury after non-cardiac surgery patients who had preoperative cardiac troponin (cTn) measurements. Within these patients, 945 patients were evaluated by cardiologists, and the incidence of 30-day morality was...

Heartbeat: sex disparities in stroke, heart failure and all-cause mortality in adults with coronary heart disease
Research on sex disparities in patients with coronary heart disease (CHD) largely has focused on events directly related to the coronary arteries themselves—recurrent myocardial infarction, revascularisation and cardiovascular death—rather than the wider consequences of atherosclerotic vascular disease. In contrast, Akyea and colleagues1 evaluated sex disparities across a broader range of major adverse cardiovascular events (MACE) including not only recurrent CHD, but also stroke, peripheral vascular disease, heart failure and all-cause mortality in a population-based cohort of 143 702 adults (median age 73 yea...

Risk of left atrial appendage thrombus and stroke in patients with atrial fibrillation and mitral regurgitation
Conclusions Among patients with NVAF, the presence or severity of MR was not associated with a decreased risk of LAAT or stroke.

Sex disparity in subsequent outcomes in survivors of coronary heart disease
Conclusions After incident CHD, women have lower risk of composite MACE and recurrent CHD outcomes but higher risk of stroke, heart failure, and all-cause mortality compared with men.

Developing and validating a cardiovascular risk score for patients in the community with prior cardiovascular disease
Conclusions The PREDICT-CVD secondary prevention score uses routine measurements from clinical practice that enable it to be implemented in a primary care setting. The score will facilitate risk communication between primary care practitioners and patients with prior CVD, particularly as a resource to show the benefit of risk factor modification.

Cochrane corner: self-monitoring and self-management of oral anticoagulation
Background Use of oral anticoagulants such as warfarin is increasing. Part of the reason for this is the rising prevalence of atrial fibrillation, an ageing population and the widening indications for treatment based on evidence of benefit in reducing risk of stroke. A meta-analysis of 29 randomised trials including 28 044 participants with atrial fibrillation found that warfarin decreased the absolute risk of stroke by 2.7% per year (the number needed to treat (NNT) 37) compared with placebo or no treatment and by 0.7% per year (NNT=143) compared with aspirin.1 Management of warfarin, however, is challenging bec...

Oral anticoagulation in end-stage renal disease and atrial fibrillation: is it time to just say no to drugs?
Atrial fibrillation (AF) frequently complicates the management of chronic kidney disease, especially in patients with end-stage renal disease (ESRD). AF occurs in approximately one in five of the 650 000 patients with ESRD in the USA.1 ESRD confers increased risk for AF, while AF hastens progression to ESRD. The presence of chronic kidney disease in patients with AF is associated with an increased risk for ischaemic stroke independent of traditional risk factors. In addition, chronic kidney disease and particularly ESRD are associated with an increased risk of bleeding. Little is understood about how to safely reduce ...

Long-term prognostic impact of left atrial volumes and emptying fraction in a community-based cohort
Conclusions In this community-based cohort, LAEF was a powerful predictor of incident cardiovascular events and its predictive ability was stronger than for LA volumes. Our findings suggest that LA dysfunction may represent a more advanced state of LA remodelling than LA enlargement.

How heavy is the load? The ventricular mechanics of mitral regurgitation revisited in the era of percutaneous therapies
The impact of mitral regurgitation (MR) on left ventricular (LV) function and remodelling has been typically described in terms of a pure volume overload. In fact, LV afterload in MR is sometimes believed to be below normal ‘because the regurgitant orifice allows blood to exit the ventricle with little opposition’. Moreover, this argument sometimes is followed by the idea that a low-afterload leads to overestimate intrinsic LV systolic function in MR. Remarkably, despite a number of authors have emphasised that afterload is not reduced in chronic MR,1 2 the idea is still prevalent. Describing MR merely as a vol...

A tragedy of modern cardiology: using ejection fraction to gauge left ventricular function in mitral regurgitation
Mechanics The normal mitral valve provides unidirectional flow from left atrium (LA) to left ventricle (LV) in a smooth and efficient fashion. Mitral incompetence allows backward flow into the LA, requiring the LV to pump additional volume to compensate for that lost to regurgitation (MR). In its compensated state, even severe chronic MR is remarkably well tolerated at least for short periods of time. Patients are often totally asymptomatic, and many can achieve normal results during cardiopulmonary stress testing, objective proof that symptom absence is based upon true physiological compensation for the existing pathologi...

Non-major bleeding with apixaban versus warfarin in patients with atrial fibrillation
Conclusions In ARISTOTLE, non-major bleeding was common and substantially less frequent with apixaban than with warfarin. CRNM bleeding was independently associated with a higher risk of death and subsequent major bleeding. Our results highlight the importance of any severity of bleeding in patients with AF treated with anticoagulation therapy and suggest that non-major bleeding, including minor bleeding, might not be minor. Trial registration number NCT00412984; post-results.

Cautious anticoagulation strategy in patients with dialysis-requiring end-stage kidney disease
To the Editor: We read with interest this manuscript which demonstrated in a large clinical registry that patients with chronic kidney disease with indications for anticoagulation were often treated subtherapeutically.1 A more aggressive approach was, therefore, advocated. We would like to point out that, while this study should be commended for including a large number of patients, it did not show data on the key clinical outcomes of stroke or bleeding. We feel, therefore, that a clear association cannot be made between low time in the therapeutic range (TTR) and any negative clinical outcome. In fact, paradoxically,...
