MedicalResearch.com: What is the background for this study? What are the main findings?

Response: High intensity statin therapy is underutilized in patients with acute coronary syndromes. In 2011, 27% of patients were discharged on a high intensity statin (Rosenson RS, et al. J Am Coll Cardiol).

In this report, we investigate the factors associated with high adherence to high intensity statin. High adherence to high intensity statins was more common among patients who took high intensity statin prior to their hospitalization, had fewer comorbidities, received a low-income subsidy, attended cardiac rehabilitation and more visits with a cardiologist.

Response: The 2013 ACC/AHA guidelines for treatment of blood cholesterol to prevent cardiovascular disease created a new paradigm for lipid management and raised numerous ongoing controversies.

In 2016, the US Preventive Services Task Force released recommendations for primary prevention statin therapy which were different in some important ways from the 2013 ACC/AHA guidelines. We aimed to understand the practical difference between these two sets of guidelines in terms of the number of Americans who would be potentially eligible for statin therapy. Using U.S. cross-sectional survey data between 2009 and 2014, we found that, if fully implemented, the USPSTF recommendations would reduce the percentage of US adults age 40-75 who should initiate statin therapy from 24% to 16% as compared to the 2013 ACC/AHA guidelines. Those newly recommended for statin therapy would be in addition to the 21% of US adults already taking lipid-lowering therapy.

Of the approximately 9 million adults who would no longer be recommended to receive statin therapy under the new USPSTF recommendations, over half of them would be younger adults with a high long-term risk of cardiovascular disease (about 1 in 3), and over one quarter would be individuals with diabetes.

MedicalResearch.com: What is the background for this study?

Response: Three in 10 stroke survivors will go on to have a further stroke, which causes greater disability or even death. Secondary prevention medications, including antihypertensives, blood thinning and lipid lowering agents, such as statins, can reduce risk of stroke recurrence by up to 75 per cent. However, patients’ persistence with these medications decreases over time because a minority of people experience side effects, which are mild in most cases.

The analysis, involving Queen Mary University of London and the University of Cambridge and published in the journal Family Practice, was performed on the archives from TalkStroke, a UK online forum hosted by the Stroke Association. The forum is used by patients with stroke and their carers, and generated 21,596 posts during 2004-2011. 50 participants were found to discuss GP advice on prevention medications in 43 discussion threads.

Older Women Face Greater Risk of Diabetes From Statins

MedicalResearch.com Interview with:
Dr Mark Jones, Senior Lecturer
Faculty of Medicine and Biomedical Sciences, School of Public Health
The University of Queensland

MedicalResearch.com: What is the background for this study?

Response: Multiple clinical trials have shown statins reduce LDL cholesterol, cardiovascular events, and all-cause mortality. However statins are also associated with adverse events, including type 2 diabetes. There have been very few older women included in statin trials hence effects of the drug in this population are somewhat uncertain. Also, more generally, results from clinical trials may not translate well into clinical practice.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Unlike the previous cholesterol management guideline that recommended use of either statin and non-statin therapy to achieve low density lipoprotein cholesterol (LDL-C) target, the 2013 American College of Cardiology/American Heart Association cholesterol management guideline made a major paradigm shift by recommending statin focused treatment in 4 specific patient groups and replaced LDL-C target with fixed statin intensity treatment (moderate to high intensity statin therapy).

With this change, it was speculated that a large number of patients would be eligible for statin treatment (in one study, up to 11.1% additional patients were expected to be eligible for statin therapy). Our study provided the real world trends in the use of statin and non-statin lipid lowering therapy (LLT) from a national sample of cardiology practices in 1.1 million patients 14 months before and 14 months after the release of the 2013 guideline.

We found a modest, but significant increasing trend in the use of statin therapy in only 1 of the 4 patient groups eligible for statin therapy (i.e., 4.3% increase in the use of moderate to high intensity statin therapy in patients with established atherosclerotic cardiovascular disease). We did not find any significant change in non-statin LLT use. Importantly, about a third to half of patients in statin eligible groups were not receiving moderate to high intensity statin therapy even after the publication of the 2013 guideline.

MedicalResearch.com: What is the background for this study?

Response: Statins are well established for the prevention of cardiovascular disease and this is based on their ability to lower levels of circulating lipids in the blood. However, statins are also known to have pleotropic effects and these include potential protective effects on multiple disease conditions.

Based on their anti-inflammatory and antithrombotic properties, there have been suggestions that statins may prevent venous thromboembolism (VTE) (which comprises of pulmonary embolism and deep vein thrombosis). The evidence is however uncertain. Several studies utilizing both observational cohort and randomized controlled designs have been conducted to evaluate whether statin therapy or use is associated with a reduction in the incidence of VTE, but the results have been inconclusive. In a recent review that was published in 2012, Rahimi and colleagues pooled the results of several randomized controlled trials (RCTs), but found no significant reduction in the risk of VTE with statin therapy [REF]. Given the publication of new studies since this study was published and the existing uncertain evidence on the effect of statins on VTE, we decided it was time to bring all the evidence together and evaluate if statin therapy really did have a protective effect on the risk of venous thromboembolism.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: This manuscript presents the findings of extended follow up of patients with Type 2 Diabetes who were treated with fenofibrate, a member of a group of triglyceride lowering medications known as fibrates or PPAR alpha agonists, as part of the Action to Control Cardiovascular Risk in T2DM (ACCORD) study.

ACCORD was designed to test the effect of intensive treatment of cardiovascular risk factors including blood glucose, blood pressure and lipids on risk of heart attack, stroke and cardiac death in patients with Type 2 Diabetes.

The lipid arm of ACCORD tested the hypothesis that adding fenofibrate to statin therapy would further reduce risk of these cardiovascular events.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: The 2013 ACC/AHA cholesterol management guidelines emphasized that high-risk patients with atherosclerotic disease should be on high-intensity statins. We sought to determine how these guidelines are being adopted at the Veterans Affairs (VA) Health System and to identify treatment gaps.

Our main findings were that the use of high-intensity statins increased from 23 to 35% following the guideline release for these high-risk patients. However, high-intensity statin use was lowest in Hispanics and Native Americans. Women, older adults, and patients with peripheral arterial and cerebrovascular disease were also less likely to undergo statin intensification after the release of the guideline. We also noted geographic and institutional differences across VA hospitals in rates of high-intensity statin use for secondary prevention.

Cardioprotective Effect of PCSK9 Inhibitors Should Outweigh Potential Harm of Diabetes Risk

MedicalResearch.com Interview with:
Brian A. Ference, M.D
Division of Cardiovascular Medicine
Wayne State University School of Medicine
Detroit, MI

MedicalResearch.com: What are the main findings?

Response: Lifelong exposure to modestly lower plasma LDL-C levels caused by rare loss-of-function mutations in the PCSK9 gene is associated with a substantially lower lifetime risk of developing cardiovascular disease. This discovery motivated the development of monoclonal antibodies directed against PCSK9 which have now been shown to reduce plasma LDL-C levels by 50-60%. The cardiovascular medicine community is early anticipating the results of two large cardiovascular outcome trials that will determine if lowering LDL-C levels by inhibiting PCSK9 will reduce the risk of cardiovascular events.

Because monoclonal antibodies and other therapies directed against PCSK9 are designed to recapitulate the phenotype of PCSK9 loss-of-function mutations, we reasoned that it may be possible to anticipate the efficacy and safety results of the ongoing cardiovascular outcome studies by more precisely characterizing the effect of genetic variants in the PCSK9 gene on the risk of both cardiovascular events and new onset diabetes.

To do this, we a constructed genetic score consisting of multiple independently inherited variants in the PCK9 gene to create an instrument that mimics the effect of PCSK9 inhibitors. We then compared the effect of genetic variants that mimic the effect of PCSK9 inhibitors with the effect of genetic variants in the HMGCR gene that mimic the effect of statins to make inferences about the likely effect of PCSK9 inhibitors on the risk of cardiovascular events and new onset diabetes as compared to treatment with a statin.

MedicalResearch.com: What is the background for this study?
What are the main findings?

Response: Dabigatran etexilate is an anticoagulant that is commonly used for stroke prevention in patients with atrial fibrillation. Absorption of dabigatran etexilate is opposed by intestinal P-glycoprotein, an efflux transporter. Once absorbed, dabigatran etexilate is converted to its active form by carboxylesterase enzymes. Unlike other statins, simvastatin and lovastatin can inhibit P-glycoprotein and carboxylesterase. This may result in increased absorption of dabigatran etexilate, thereby increasing the risk of bleeding. Conversely, inhibition of carboxylesterase may decrease the effectiveness of dabigatran etexilate.

MedicalResearch.com: What is the background for review and statement?

Response: Cardiovascular disease is serious—it can lead to heart attacks and strokes, and is responsible for one in every three adult deaths in the U.S. People with no signs or symptoms and no past history of cardiovascular disease can still be at risk. Fortunately, some people can benefit from taking a medication called statins to reduce that risk.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Statins are widely used to treat hypercholesterolemia. In addition to their effect on cholesterol levels, statins also attenuate inflammation and have immunomodulatory properties. Whether this translates into meaningful differences in health outcomes, though, remains uncertain. We therefore undertook this study to determine whether people exposed to high doses of statins were at a lower risk of developing rheumatoid arthritis compared to those at lower doses. We studied a large population-based cohort of over half a million people exposed to statins for the first time and followed them on average for 3 years.

We found that those exposed to the highest intensity statin quintile had a 33% lower risk of developing rheumatoid arthritis compared to those in the lowest intensity quintile (adjusted HR 0.77; 95% CI: 0.63-0.95). We conducted several additional secondary analyses that all pointed in the same direction and suggested that statins reduce the risk of rheumatoid arthritis.
