Randomized Controlled Trial
Icosapent ethyl (eicosapentaenoic acid ethyl ester): Effects on remnant-like particle cholesterol from the MARINE and ANCHOR studies.
Remnant-like particle cholesterol (RLP-C) is atherogenic and may increase atherosclerotic cardiovascular disease risk. Icosapent ethyl is a high-purity prescription eicosapentaenoic acid ethyl ester (approved as an adjunct to diet to reduce triglyceride [TG] levels in adult patients with TGs ≥500 mg/dL [≥5.65 mmol/L] at 4 g/day). In the MARINE and ANCHOR studies, icosapent ethyl reduced TG and other atherogenic lipid parameter levels without increasing low-density lipoprotein cholesterol (LDL-C) levels. This exploratory analysis evaluated the effects of icosapent ethyl on calculated and directly measured RLP-C. ⋯ Icosapent ethyl 4 g/day significantly reduced calculated and directly measured RLP-C levels versus placebo in patients with elevated TG levels from the MARINE and ANCHOR studies.

Increasing knowledge about the influence of genetic variation on human health and growing availability of reliable, cost-effective genetic testing have spurred the implementation of genomic medicine in the clinic. As defined by the National Human Genome Research Institute (NHGRI), genomic medicine uses an individual's genetic information in his or her clinical care, and has begun to be applied effectively in areas such as cancer genomics, pharmacogenomics, and rare and undiagnosed diseases. In 2011 NHGRI published its strategic vision for the future of genomic research, including an ambitious research agenda to facilitate and promote the implementation of genomic medicine. ⋯ These meetings have identified and begun to address significant obstacles to implementation, such as lack of evidence of efficacy, limited availability of genomics expertise and testing, lack of standards, and difficulties in integrating genomic results into electronic medical records. The six research and dissemination initiatives comprising NHGRI's genomic research portfolio are designed to speed the evaluation and incorporation, where appropriate, of genomic technologies and findings into routine clinical care. Actual adoption of successful approaches in clinical care will depend upon the willingness, interest, and energy of professional societies, practitioners, patients, and payers to promote their responsible use and share their experiences in doing so.

Review Meta Analysis
Bisphosphonates for cardiovascular risk reduction: A systematic review and meta-analysis.
Bisphosphonates might be effective in reducing cardiovascular events due to their ability to reduce calcification in arterial walls. We aimed to investigate the effects of treatment with bisphosphonates on the prevention of atherosclerotic processes and cardiovascular disease. ⋯ In this systematic review and meta-analysis it is shown that bisphosphonates reduce arterial wall calcification but have no effect on arterial stiffness or on cardiovascular events. Bisphosphonates tend to reduce the risk of cardiovascular mortality and reduce all-cause mortality in various patient groups, including osteoporosis and cancer patients.

Meta Analysis
Aspirin and cardiovascular primary prevention in non-endstage chronic kidney disease: A meta-analysis.
Chronic kidney disease is a strong independent predictor of cardiovascular disease. No published meta-analyses on the use of aspirin for the primary prevention of cardiovascular disease in chronic kidney disease exist. We therefore performed a systematic review and meta-analysis of this subject. ⋯ There is no clear benefit of aspirin for the primary prevention of cardiovascular events in CKD and no statistically significant reduction in mortality. Aspirin is likely to increase the risk of major bleeding events. Currently, insufficient randomised control trial data exists to recommend universal use or avoidance of aspirin for primary prevention of cardiovascular events in CKD.

Acute hypertensive response (AHR) affects more than 60% of patients with ischemic stroke and is associated with poor outcomes. We hypothesized that its development is related to arterial stiffening. "The gold standard" estimate of arterial stiffness is carotid-femoral pulse wave velocity (CF-PWV). We compared CF-PWV and indirect indices of arterial stiffness (central augmentation index (cAIxHR), central systolic (cSBP) and pulse (cPP) pressures) between acute ischemic stroke patients who developed AHR and those who were normotensive in the early phase of stroke. ⋯ This study revealed for the first time that AHR in ischemic stroke is associated with elevated aortic stiffness independently of other clinical factors including age and hypertension preceding stroke. A potential pathophysiological mechanism responsible for this relationship includes impaired baroreceptor function in stiff arteries resulting in impaired BP autoregulation.
