The drug efficacy may differ among different statins, and evidence from head-to-head comparisons is sparse and inconsistent. The study is aimed at comparing the lipid-lowering/increasing effects of 7 different statins in patients with dyslipidemia, cardiovascular diseases, or diabetes mellitus by conducting systematic review and network meta-analyses (NMA) of the lipid changes after certain statins' use. ⋯ According to the NMAs, it can be concluded that rosuvastatin ranked 1st in LDL-C, ApoB-lowering efficacy and ApoA1-increasing efficacy. Lovastatin ranked 1st in TC- and TG-lowering efficacy, and fluvastatin ranked 1st in HDL-C-increasing efficacy. The results should be interpreted with caution due to some limitations in our review. However, they can provide references and evidence-based foundation for drug selection in both statin monotherapies and statin combination therapies.

Catheter ablation for atrial fibrillation (AF) is associated with a transitory increase in the risk of both thromboembolic and bleeding events. Evidence on the use of nonvitamin K antagonist oral anticoagulants (NOACs) in patients undergoing AF ablation mostly comes from small observational studies, underpowered to detect differences in clinical outcomes between NOACs and vitamin K antagonists (VKAs) treated patients. This updated meta-analysis aimed to determine the safety and efficacy of periprocedural anticoagulation with NOACs compared with VKAs in AF patients undergoing catheter ablation. ⋯ Use of NOACs compared to VKAs significantly reduced the risk of bleeding in patients with AF ablation. Similarly, the risk of bleeding was lower with uninterrupted NOACs than with uninterrupted VKAs, and with interrupted NOACs than with interrupted VKAs. The rate of thromboembolic complications was extremely low in both study groups without any differences.

Review
Adherence to therapies for secondary prevention of cardiovascular disease: a focus on aspirin.
Suboptimal adherence to medications taken chronically for secondary prevention of cardiovascular disease (CVD, e.g., aspirin) continues to burden the healthcare system despite the well-established benefits of prevention. We conducted a literature search to examine patient adherence to medications for secondary prevention of CVD-as evaluated by prescription refill data, electronic medication monitors, pill counts, and physiologic markers-to better identify an unmet need for measures to improve patient adherence to these therapies. ⋯ Given the burden of CVD to the community and the healthcare system, nonadherence to CVD-preventative medications such as aspirin remains a substantial area of unmet need and represents a key opportunity for the development of quality-of-care enhancement programs to improve health outcomes in this patient population.

Review Meta Analysis
The Role of Vascular Imaging in Guiding Routine Percutaneous Coronary Interventions: A Meta-Analysis of Bare Metal Stent and Drug-Eluting Stent Trials.
The routine use of vascular imaging including intravascular ultrasound (IVUS) and optical coherence tomography (OCT) in guiding percutaneous coronary interventions (PCI) is still controversial especially when using drug-eluting stents. A meta-analysis of trials using bare metal stents was previously published. ⋯ Imaging-guided PCI significantly lowered the risk of death, MI, stent thrombosis, and the combined MACE in DES-implanted patients and all stented patients (DES or BMS). However, imaging guidance had no significant effect on repeated target vessel or target lesion revascularization in patients who received DES, likely due to the effect of the drug in the stent.

Review Meta Analysis
Administration of antiarrhythmic drugs to maintain sinus rhythm after catheter ablation for atrial fibrillation: a meta-analysis.
Whether the short-term administration of antiarrhythmic drugs (AADs) to maintain sinus rhythm following catheter ablation (CA) for atrial fibrillation (AF) can prevent the recurrence of AF is still a matter of debate. We searched the PubMed database and the Cochrane Library, and compiled a list of retrieved articles. We included only randomised controlled trials(RCTs) that compared any AADs against control (placebo or no treatment) or other AADs following CA for AF. Statistical analysis of the odds ratio (OR) and corresponding 95% confidence interval (CI) were used to determine the overall effect of both outcomes. The Mantel-Haenszel method was used to pool data of the outcomes of AF recurrence into fixed effect model meta-analyses. ⋯ Although the continued administration of AADs after CA for AF can decrease early atrial tachycardias (ATa), this treatment does not prevent late ATa.
