Differential effects of PCSK9 variants on risk of coronary disease and ischaemic stroke
ConclusionPCSK9 genetic variants that confer life-long lower PCSK9 and LDL-C levels appear to have significantly weaker, if any, associations with risk of IS than with risk of CHD. By contrast, similar proportional reductions in risks of IS and CHD have been observed in randomized trials of therapeutic PCSK9-inhibition. These findings have implications for our understanding of when Mendelian randomization can be relied upon to predict the effects of therapeutic interventions.

Blood pressure and in-hospital outcomes in patients presenting with ischaemic stroke
ConclusionIn patients hospitalized with ischaemic stroke, J-shaped, or U-shaped relationships were observed between BP variables and short-term outcomes. However, haemorrhagic complications with thrombolytic therapy were lower with lower BP.

Benefit of switching dual antiplatelet therapy after acute coronary syndrome: the TOPIC (timing of platelet inhibition after acute coronary syndrome) randomized study
ConclusionA switched DAPT is superior to an unchanged DAPT strategy to prevent bleeding complications without increase in ischaemic events following ACS.

Transcatheter aortic valve thrombosis: the relation between hypo-attenuated leaflet thickening, abnormal valve haemodynamics, and stroke
Conclusion</div>On MDCT, 12.5% of patients showed HALT or reduced leaflet motion, whereas only one of these patients had abnormal valve haemodynamics on echocardiography. Neither HALT nor increased transvalvular gradient were associated with stroke/TIA.</span>

Foreign body granuloma as an unexpected long-term finding after percutaneous closure of a patent foramen ovale
A 67-year-old man was referred to our hospital for catheter ablation of atrial fibrillation. Eight years earlier, prior to diagnosis of atrial fibrillation, the patient suffered an ischaemic stroke. A patent foramen ovale (PFO) was diagnosed and the patient underwent percutaneous PFO closure by implantation of a Premere device (20  mm, St. Jude Medical). One month ago, the patient had another middle-cerebral artery infarction, which was considered cardioembolic due to insufficient anticoagulation. However, transthoracic echocardiography (TTE) obtained on current admission demonstrated a suspicious mass in the left atrium...

Revisiting sex differences in outcomes in non-valvular atrial fibrillation: a population-based cohort study
ConclusionIn NVAF, women were not at higher risk of thromboembolic events than men in our study. The small increased risk reported in previous studies may be related to residual confounding, in particular from insufficient control for age.

Outcomes in patients treated with ticagrelor or clopidogrel after acute myocardial infarction: experiences from SWEDEHEART registry
Conclusion Ticagrelor vs. clopidogrel post-ACS was associated with a lower risk of death, MI, or stroke, as well as death alone. Risk of bleeding was higher with ticagrelor. These real-world outcomes are consistent with randomized trial results.

Comparison of the ATRIA, CHADS2, and CHA2DS2-VASc stroke risk scores in predicting ischaemic stroke in a large Swedish cohort of patients with atrial fibrillation
Conclusion In this SAF cohort, the ATRIA score predicted ischaemic stroke risk better than CHADS2 or CHA2DS2-VASc. However, relative performance of the categorical scores varied by population stroke rates. Score cut-points may need to be optimized to better fit local population stroke rates.

Ischaemic and haemorrhagic stroke associated with non-vitamin K antagonist oral anticoagulants and warfarin use in patients with atrial fibrillation: a nationwide cohort study
Conclusions</div>Among anticoagulant-naïve AF patients, treatment with NOACs was not associated with significantly lower risk of stroke/TE compared with VKA, but intracranial bleeding risk was significantly lower with dabigatran and apixaban.</span>

A frameshift deletion in the sarcomere gene MYL4 causes early-onset familial atrial fibrillation
Conclusions</div>Through a population approach we found a loss of function mutation in the myosin gene <span style="font-style:italic;">MYL4</span> that, in the homozygous state, is completely penetrant for early-onset AF. The finding may provide novel mechanistic insight into the pathophysiology of this complex arrhythmia.</span>

Left atrial appendage occlusion: rationale, evidence, devices, and patient selection
<span class="paragraphSection">Atrial fibrillation (AF) is a worldwide epidemic associated with significant morbidity and mortality, often due to disabling or fatal thromboembolic stroke. Oral anticoagulation is highly effective at preventing ischaemic stroke and improving all-cause survival in patients with non-valvular AF. Despite the efficacy of oral anticoagulation, many patients are not treated due to either absolute or perceived contraindications to therapy, including bleeding. Left atrial appendage (LAA) closure has emerged as a mechanical alternative to pharmacologic stroke prevention. Initial and mid-term cl...
