Effects of Anticoagulation on Low-Density Lipoprotein-Cholesterol and Ischemic Stroke in Patients with Nonvalvular Atrial Fibrillation
The study by Omelchenko et al1 concluded that, unlike the general population, low-density lipoprotein-cholesterol (LDL-C) levels were not associated with ischemic stroke risk among patients with atrial fibrillation treated with direct oral anticoagulants (DOACs). To arrive at this conclusion, they retrospectively analyzed data of 21,229 patients with a first-time diagnosis of nonvalvular atrial fibrillation treated with DOACs categorized according to the congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, stroke or transient ischemic attack (TIA), vascular disease, age 65 to 74 years, sex category, ...

Cholesterol lowering and stroke: no longer room for pleiotropic effects of statins – confirmation from PCSK9 inhibitor studies
The relationship between cholesterol levels and stroke has been much less clear than between cholesterol levels and coronary heart disease. This is likely mostly due to the inadequate power of older studies and the low intensity of cholesterol-lowering interventions at that time available. Because a reduction in stroke has been, conversely, clearly observed in trials with statins, for long “pleiotropic” effects of such drugs, unrelated to cholesterol lowering, have been invoked. In a previous analysis of all randomized trials of cholesterol-lowering treatments reporting on stroke we had, however, reached the conclusion...

Can the reduction percentage LDL-C or Attained LDL-C levels or both add incremental prognostic value?
The role of low-density lipoprotein cholesterol (LDL-C) in the pathophysiology of atherosclerotic cardiovascular disease, which may present as coronary heart disease, stroke, and peripheral arterial disease, has been well documented in several studies.1,2,3,4 The decrease in LDL-C levels leads to a significant reduction in the risk of atherosclerotic cardiovascular disease.5

Adherence to Secondary Prevention Medications and Four-year Outcomes in Outpatients with Atherosclerosis
Abstract: Background: Although nonadherence with evidence-based secondary prevention medications is common in patients with established atherothrombotic disease, long-term outcomes studies are scant. We assessed the prevalence and long-term outcomes of nonadherence to secondary prevention (antiplatelet agents, statins, and antihypertensive agents) medications in stable outpatients with established atherothrombosis (coronary, cerebrovascular, or peripheral artery disease) enrolled in the international REduction of Atherothrombosis for Continued Health registry.Methods: Adherence with these medications in eligible patients a...

CHADS2 Score, Statin Therapy, and Risks of Atrial Fibrillation
This study aimed to evaluate the efficacy of statin treatment for atrial fibrillation prevention in elderly patients with hypertension, and to determine if comorbidity or CHADS2 (Congestive heart failure, Hypertension, Age ≥75 years, Diabetes mellitus, prior Stroke or transient ischemic attack) score can predict the effectiveness of statin treatment. Methods: Patients aged ≥65 years with hypertension were identified from a National Health Insurance research database (a systemic sampling from 2000 to 2009 with a total of 1,000,000 subjects). Medical records of 27,002 patients were used in this study, in which 2400 (8....
