To conduct a prospective, individual participant data (IPD) meta-analysis of randomised controlled trials comparing a polypill-based approach with usual care in high risk individuals. ⋯ Polypill therapy significantly improved adherence, SBP and LDL-cholesterol in high risk patients compared with usual care, especially among those who were under-treated at baseline.

We tested the hypothesis that tissue plasminogen activator (tPA) deficiency protected against acute ischemic stroke (AIS)-induced brain injury. ⋯ tPA deficiency protected the brain from AIS injury.

Oral anticoagulation is crucial for the prevention of stroke and thromboembolism in atrial fibrillation (AF). One of the comorbidities potentially affecting thromboembolic risk and anticoagulation effectiveness is obstructive sleep apnea (OSA). The objective of this study was to establish if presence of OSA is associated with poor expected benefit from vitamin K antagonist (VKA) therapy as assessed using the SAMe-TT2R2 score. ⋯ SAMe-TT2R2 scores in patients with OSA are substantially higher than in those without sleep-disordered breathing. The mean SAMe-TT2R2 score, as well as the percentage of patients with SAMe-TT2R2 score ≥ 2, suggests poor predicted anticoagulation control on VKA rises along with the AHI. There was a lower proportion of patients with TTR > 70% among patients with moderate/severe OSA, compared to no/mild OSA.

Meta Analysis Comparative Study
Relative efficacy and safety of non-Vitamin K oral anticoagulants for non-valvular atrial fibrillation: Network meta-analysis comparing apixaban, dabigatran, rivaroxaban and edoxaban in three patient subgroups.
Stroke is the most serious clinical consequence of atrial fibrillation, which is the most common cardiac arrhythmia. Non-vitamin K antagonist oral anticoagulants (NOACs) have emerged as efficacious, safe and convenient stroke prevention agents. This updated network meta-analysis focused on the relative efficacy and safety of apixaban compared with dabigatran, rivaroxaban and edoxaban for stroke prevention in (i) patients with CHADS2 score ≥ 2, (ii) secondary stroke prevention, and (iii) patients with high quality anticoagulation control with warfarin. ⋯ Among the NOACs, apixaban offered the most favourable efficacy and safety profile in the overall patient population as well as in the three subgroups investigated.

Randomized Controlled Trial Multicenter Study Comparative Study
The impact of left ventricular ejection fraction on fractional flow reserve: Insights from the FAME (Fractional flow reserve versus Angiography for Multivessel Evaluation) trial.
Fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) significantly improves outcomes compared with angio-guided PCI in patients with multivessel coronary artery disease. However, there is a theoretical concern that in patients with reduced left ventricular ejection fraction (EF) FFR may be less accurate and FFR-guided PCI less beneficial. ⋯ Reduced EF has no influence on the FFR value unless the stenosis is very tight, in which case a theoretically explainable, but clinically irrelevant overestimation might occur. As a result, FFR-guided PCI remains beneficial regardless of EF.
