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,...

Cardiovascular highlights from non-cardiology journals
Continuous positive airway pressure fails to improve cardiovascular outcomes in obstructive sleep apnea Obstructive sleep apnea (OSA) is associated with increased cardiovascular events in observational studies. Randomized trials have demonstrated continuous positive airway pressure (CPAP) therapy reduces blood pressure, markers of oxidative stress and insulin insensitivity. Yet, it remains unclear whether treatment with CPAP reduces cardiovascular events.

Dipeptidyl peptidase-4 inhibitors and cardiovascular risks in patients with pre-existing heart failure
Conclusions In this nationwide T2DM cohort, the risks of mortality and the combination of MI and ischaemic stroke were lower for patients receiving DPP-4 inhibitors than for those who did not receive such treatment. DPP-4 inhibitor use was not associated with a higher risk of hospitalisation for HF even in patients with pre-existing HF.

Pre-procedural dual antiplatelet therapy in patients undergoing transcatheter aortic valve implantation increases risk of bleeding
Conclusions The current study demonstrated that DAPT before TF-TAVI increased the risk of bleeding compared with single or no antiplatelet therapy.

Net clinical benefit of warfarin in individuals with atrial fibrillation across stroke risk and across primary and secondary care
Conclusions CHA2DS2-VASc accurately stratifies IS risk in individuals with AF across both primary and secondary care. However, the incidence rate of ischaemic stroke at CHA2DS2-VASc=1 are lower than previously reported, which may change the decision to start anticoagulation with warfarin in these individuals.

Heartbeat: Left atrial appendage occlusion for stroke prevention
Stroke prevention is the primary goal of therapy in patients with atrial fibrillation (AF).1 Heart has published numerous papers on early AF detection,2 approaches for restoring normal sinus rhythm, risk scores for determining which AF patients benefit most from anti-thrombotic therapy, and transcatheter occlusion of the left atrial appendage (LAA) to prevent thrombus formation.3–6 Early studies of LAA occlusion compared this procedure to vitamin K antagonist (VKA) therapy for stroke prevention. Now, direct oral anticoagulants (DOACs) have replaced VKA therapy in many AF patients due to an improved risk/benefit profi...

To occlude or not? Left atrial appendage occlusion for stroke prevention in atrial fibrillation
The cornerstone of atrial fibrillation (AF) management is effective stroke prevention, which by now remains the only proven method of improved survival in patients with AF. Oral anticoagulation with the use of vitamin K antagonists (eg, warfarin) or non-vitamin K antagonist oral anticoagulants (NOACs) has been shown to substantially reduce the risk of AF-related strokes and thus is presently the standard of care for stroke prevention in non-valvular AF. Approximately 90% of thrombi being formed in AF are localised in left atrial appendage (LAA).1 Thus, LAA exclusion seems a tempting method of prophylaxis against stroke, pa...

Efficacy and safety of left atrial appendage closure versus medical treatment in atrial fibrillation: a network meta-analysis from randomised trials
Conclusions The findings of this meta-analysis suggest that LAAC is superior to placebo and APT, and comparable to NOAC for preventing mortality and stroke or SE, with similar bleeding risk in patients with non-valvular AF. However, these results should be interpreted with caution and more studies are needed to further substantiate this advantage, in view of the wide CIs with some variables in the current meta-analysis.

Why should we screen for atrial fibrillation?
Atrial fibrillation (AF) constitutes an increasing challenge to the medical community and healthcare providers. With a prevalence of almost 3% in the adult Swedish population1 and a forecasted twofold or threefold increase by 2050 in the USA, we are facing a diagnosis with epidemic proportions. Apart from increased mortality, AF also increases the risk of heart failure, hospitalisations and ischaemic stroke.2 Of these complications, ischaemic stroke gives a particularly heavy burden on patients, their family and society. Ischaemic stroke is the most common reason for permanent neurological disability in the adult Western p...

Screening for atrial fibrillation in 13 122 Hong Kong citizens with smartphone electrocardiogram
Conclusion Community screening for AF with SL-ECG was feasible and it identified a significant proportion of citizens with newly diagnosed AF. The prevalence of AF in a Chinese population in Hong Kong was comparable with that of contemporary Western counterparts. Apart from age and sex, different anthropometric parameters and cardiovascular comorbid conditions were identified as independent predictors of AF.

Atrial appendage occlusion for stroke prevention in patients with atrial fibrillation
In the developed countries, stroke is an important cause of mortality and disability. Cardioembolism is the most frequent cause of ischaemic stroke, in the presence of atrial fibrillation (AF).1 AF is the most common cardiac arrhythmia in the general population and its prevalence increases with age; the lifetime risk of AF development is 25% in people over 40 years old.2 Anticoagulation has been established as an effective treatment strategy for stroke prevention in patients with AF and risk factors for stroke.3 The new oral anticoagulants (NOACs) seem to be similarly efficacious compared with vitamin K antagonists (V...

Loneliness and social isolation and increased risk of coronary heart disease and stroke: clinical implications
To the Editor The recent meta-analysis published in Heart by Valtorta et al1 showed that loneliness and social isolation are associated with increased incidence of coronary heart disease (CHD) and stroke in 16 large longitudinal studies conducted in high-income countries. This finding is not surprising given the extensive literature documenting such harmful consequences of social isolation, including a study my research group published in 19922 showing in a large sample of CHD patients that those who were not married and did not have a confident—and hence likely to be lonely and socially isolated—had a 5-year m...

New perspectives on atrial fibrillation and stroke
Atrial fibrillation (AF) is directly implicated in embolic stroke and suspected in a large proportion of cryptogenic stroke. The current stroke-prevention strategy in embolic and cryptogenic stroke starts with arrhythmia detection, followed by risk stratification and treatment for those deemed to be at increased risk. This approach is practical and widespread; however, more recent findings have questioned its validity. Arrhythmia detection is dependent on the length and fidelity of monitoring. Long-term monitoring using implanted recorders improves arrhythmia detection in patients with cryptogenic stroke. A large proportio...

Hypertrophic cardiomyopathy and the potential influence of etomidate on postoperative outcomes
This study showed no difference in what they defined as ‘hard outcomes’ such as myocardial infarction, stroke and death. They did however show an increased incidence of composite end points (10%; p=0.03) such as postoperative congestive heart failure (1%) and readmission rates (7%). One interesting point that we would like to raise is the significantly higher use of etomidate in the HCM cohort (p=0.002). Understandably, etomidate was chosen in many cases for its rapid onset and stable haemodynamic properties. This was likely reflected in the significantly lower incidence of intraoperative tachycardia and hypote...

Management of supraventricular arrhythmias in adults with congenital heart disease
Supraventricular arrhythmias are a frequent complication in adults with congenital heart disease (ACHD). The prevalence increases with time since surgery, complexity of the underlying defect, type of repair and older age at surgery. Arrhythmias are the most frequent reason for hospital admission and along with heart failure the leading cause of death. The arrhythmia-associated increase in morbidity and mortality makes their management a key task in patients with ACHD. Intra-atrial re-entry is the most frequent arrhythmia mechanism. Less common arrhythmia mechanisms are supraventricular tachycardias in the presence of an ac...

Early detection of occult atrial fibrillation and stroke prevention
Atrial fibrillation (AF) is a very common arrhythmia and significantly increases stroke risk. This risk can be mitigated with oral anticoagulation, but AF is often asymptomatic, or occult, preventing timely detection and treatment. Accordingly, occult AF may cause stroke before it is clinically diagnosed. Currently, guidelines for the early detection and treatment of occult AF are limited.

To the Editor, We read with interest the recent article on survival by stroke volume index (SVI) in patients with low-gradient normal EF severe aortic stenosis, which demonstrated lower SVI is incrementally associated with mortality.1 The authors discuss a putative mechanism of low stroke volume (SV) secondary to concentric remodelling which results in reduced LV cavity size. This impedes LV diastolic filling culminating in diminished systolic function despite normal EF. The authors quote evidence of systolic impairment, for example reduced longitudinal strain, in similar cohorts with preserved EF.2 In the current study, t...

Prediction of stroke in patients without atrial fibrillation using the CHADS2 and CHA2DS2-VASc scores: a justification for more widespread thromboprophylaxis?
The CHADS2 (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, previous stroke/transient ischaemic attack (TIA) (double)) and more recently, the CHA2DS2-VASc (congestive heart failure, hypertension, age ≥75 years (double score), diabetes mellitus, previous stroke/TIA (double score), vascular disease, age 65–74 years, sex category (female)) scores are validated clinical prediction tools commonly used to estimate the stroke risk in atrial fibrillation (AF) patients. More recently, the focus has been on initially identifying those patients at ‘low risk’ (ie, CHA2DS...

Prediction of stroke or TIA in patients without atrial fibrillation using CHADS2 and CHA2DS2-VASc scores
Conclusions In patients with ACS but no AF, the CHADS2 and CHA2DS2-VASc scores predict ischaemic stroke/TIA events with similar accuracy to that observed in historical populations with non-valvular AF, but with lower absolute event rates. Further study of the utility of the CHADS2 and CHA2DS2-VASc scores for the assessment of thromboembolic risk and selection of antithrombotic therapy in patients without AF is warranted.

Right ventricular stroke work in children with pulmonary arterial hypertension: a promising approach
To the Editor, We read with great interest the article by Di Maria et al,1 describing the importance of RV performance, especially RV stroke work (RVSW), in children with pulmonary arterial hypertension (PAH). The authors investigated the relation between echocardiographic measurements of RV function and the ‘gold standard’ of right heart catheterisation in children and found that RVSW strongly correlates with non-invasive data of RV function.1 The authors concluded that RVSW correlates with outcome parameters, for example, abnormal WHO class, and mortality, in children with PAH. We completely agree with the fi...

RV stroke work in children with pulmonary arterial hypertension: estimation based on invasive haemodynamic assessment and correlation with outcomes
Conclusions RVSW can be estimated in children with PAH, and is significantly associated with abnormal WHO class, the need for septostomy, as well as mortality. Indices accounting for RV performance as well as ventricular-vascular coupling may be useful in the prognosis and, hence, management of children with PAH.

Allopurinol reduces brachial and central blood pressure, and carotid intima-media thickness progression after ischaemic stroke and transient ischaemic attack: a randomised controlled trial
Conclusions Allopurinol lowered CBP and reduced CIMT progression at 1 year compared with placebo in patients with recent ischaemic stroke and TIA. This extends the evidence of sustained beneficial effects of allopurinol to these prognostically significant outcomes and to the stroke population, highlighting the potential for reduction in cardiovascular events with this treatment strategy. Trial registration number ISRCTN11970568.
