A Clinicians Guide to Recommending Common Cholesterol-Lowering Dietary Supplements.

The US dietary supplement (DS) market has expanded exponentially since 1994, with an estimated 50,000-80,000 individual products currently available. Many DS claim cholesterol or cardiovascular benefits. Overall, well-designed randomized controlled trials (RCTs) with DS are lacking, while studies with favorable results are commonly performed outside of the USA, resulting in inconsistent findings.

Elevated Lp(a): Guidance for Identifying and Managing Patients.

Lipoprotein(a) (Lp(a)) is a unique low-density lipoprotein-like lipoprotein that is considered an independent and causal risk factor for atherosclerotic cardiovascular disease (ASCVD) and calcific aortic valve stenosis. The Lp(a) molecule also contains apolipoprotein A and apolipoprotein B, which collectively promote atherosclerosis, thrombosis, and inflammation. Lp(a) is highly genetic and minimally responsive to nonpharmacological measures.

Lipid lowering therapy: implications of recent clinical trials.

Recent lipid lowering therapy trials have provided important insights on certain agents while also continuing to expand our understanding of atherosclerotic cardiovascular disease (ASCVD) risk. Findings from current trials include the impact of statin therapy on ASCVD among populations with HIV, the benefit of lowering low-density lipoprotein cholesterol with bempedoic acid among patients considered statin intolerant, the safety and efficacy of inclisiran over a 4-year period, another failed attempt for fibrates to reduce ASCVD risk, which omega-3 fatty to utilize for lowering cardiovascular events, 'n-of-1' trials evaluating statin intolerance, and how low-dose rosuvastatin compared with commonly utilized supplements for lowering lipid parameters. Such data help inform so clinicians can optimize lipid lowering therapy and improve ASCVD outcomes.

Atherosclerotic Cardiovascular Disease in Women: Providing Protection With Lipid-altering Agents.

Purpose: Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of death in women, yet it remains underdiagnosed, undertreated, and understudied in women compared with men. Although estrogen has provided observational evidence of cardioprotection, randomized controlled trials using hormone replacement therapy have generally produced unfavorable results.

Methods: For this narrative review, a literature search was performed using the key words cardiovascular disease, women, and dyslipidemia in PubMed and Google Scholar with no date limitations.

Identifying patient perceptions and attitudes regarding statin-associated diabetes mellitus: a mixed-methods study.

The aims of this study were to explore factors that influence initiation and continuation of statin therapy. Mixed-method design employed with 73 patients completing surveys and 14 patients participating in semi-structured interviews. When lower total cholesterol is achieved, patients' views are favorable while views of statin therapy diminish among those with higher total cholesterol values.

Statin-associated muscle symptoms-A review: Individualizing the approach to optimize care.

The 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, also known as "statins" are considered first-line pharmacologic therapy for reducing low-density lipoprotein cholesterol (LDL-C). They have been demonstrated efficacy in a variety of patients populations to reduce atherosclerotic cardiovascular disease (ASCVD) risk. Like any pharmacologic therapy, however, they are not without possible adverse effects that can lead to discontinuation, thus leading to a loss of benefit.

New and emerging lipid-lowering therapy.

Statins remain the drugs of choice in patients at risk of or with atherosclerotic cardiovascular disease (ASCVD). Statins have limitations that drive the development of investigational agents to manage dyslipidemias and/or reduce ASCVD risk. There are a few small-molecule drugs that have the potential to mitigate ASCVD risk either alone or in combination with statins.

Comparing patients' prescribed, self-reported, and actual intake of supplemental eicosapentaenoic acid + docosahexaenoic acid.

Background: Dietary fish oil supplements containing the omega-3 polyunsaturated fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are frequently used for cardiovascular benefit. However, several factors may limit the intake of prescribed doses.

Objective: The objective of this study is to compare the prescribed, patient self-reported, and actual intake of supplemental EPA + DHA doses in a lipid-specialty clinic and identify common barriers and influences to therapy.

Variability in Potency Among Commercial Preparations of Berberine.

Berberine is an isoquinoline alkaloid plant extract that is widely available as a dietary supplement in the United States and has demonstrated efficacy in the treatment of type 2 diabetes mellitus and dyslipidemia. Because of its increased use and purported pharmacological properties, potential variations in product quality could pose a barrier to berberine's safety and effectiveness in clinical practice. Thus, this study evaluated the potency of dietary supplements containing berberine available in the U.

Statin-associated muscle symptoms-Managing the highly intolerant.

Musculoskeletal symptoms are the most commonly reported adverse effects associated with statin therapy. Yet, certain data indicate that these symptoms often present in populations with underlying musculoskeletal complaints and are not likely statin related. Switching statins or using lower doses resolves muscle complaints in most patients.

The clinical relevance of omega-3 fatty acids in the management of hypertriglyceridemia.

Hypertriglyceridemia (triglycerides > 150 mg/dL) affects ~25 % of the United States (US) population and is associated with increased cardiovascular risk. Severe hypertriglyceridemia (≥ 500 mg/dL) is also a risk factor for pancreatitis. Three omega-3 fatty acid (OM3FA) prescription formulations are approved in the US for the treatment of adults with severe hypertriglyceridemia: (1) OM3FA ethyl esters (OM3EE), a mixture of OM3FA ethyl esters, primarily eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (Lovaza®, Omtryg™, and generics); (2) icosapent ethyl (IPE), EPA ethyl esters (Vascepa®); and (3) omega-3 carboxylic acids (OM3CA), a mixture of OM3FAs in free fatty acid form, primarily EPA, DHA, and docosapentaenoic acid (Epanova®).

Statin-Associated Diabetes Mellitus: Review and Clinical Guide.

A small but significant link between new-onset diabetes mellitus (NOD) and statin therapy was noted with rosuvastatin users in the Justification for the Use of Statins in Primary Prevention: An Intervention Trial Evaluating Rosuvastatin study. Since then multiple analyses have further confirmed this association, with most studies demonstrating a modest increase in NOD with statin therapy, especially among individuals with risk factors for developing diabetes mellitus. More recent observational analyses suggest a stronger correlation between statin use and NOD, however.

Hypertriglyceridaemia unresponsive to multiple treatments.

A 52-year-old man with a longstanding history of hypertriglyceridaemia (approximately 7 mmol/L (600 mg/dL)), unresponsive to treatment, presented to a lipid-specialty clinic. Additional triglyceride-lowering therapies were added with no effect. It was then noted that despite the apparent hypertriglyceridaemia, his serum sample was clear.

Statins and almonds to lower lipoproteins (the STALL Study).

Background: Dietary supplementation with almonds has demonstrated dose-dependent decreases in low-density lipoprotein cholesterol (LDL-C), likely because of their composition of beneficial nutrients including mono- and polyunsaturated fatty acids, fiber, and protein.

Objective: The primary objective of this study was to determine the changes in the lipid profile (LDL-C, high-density lipoprotein cholesterol [HDL-C], triglycerides, total cholesterol, non-HDL-C), LDL-C particle size, and lipoprotein (a) when 100 g of almonds daily were added to background statin therapy for 4 weeks.

Methods: Subjects (N = 48) receiving a consistent statin dose were randomized to 100 g of almonds daily and to The National Cholesterol Education Program Adult Treatment Panel's third report Therapeutic Lifestyle Changes Diet counseling (almond group; n = 22) or solely Adult Treatment Panel's third report Therapeutic Lifestyle Changes Diet counseling (non-almond group; n = 26), for 4 weeks.

Krill oil for cardiovascular risk prevention: is it for real?

Omega-3 fatty acids play an important role in cardiovascular health. Although it is suggested that individuals obtain these nutrients through diet, many prefer to rely on supplements. Fish oil supplements are widely used, yet large capsule sizes and tolerability make them less than ideal.

Apple pectin for the reduction of niacin-induced flushing.

Background: Niacin, or vitamin B3, when used in high doses can significantly improve the levels of all major lipoproteins. Despite these benefits, the use of niacin is greatly limited secondary to benign yet bothersome cutaneous flushing primarily involving the face and upper extremities. Pretreatment with aspirin or other prostaglandin inhibitors has demonstrated significant reductions in niacin-induced flushing (NIF), but other treatment options are needed.

Pseudohypertriglyceridemia: two cases of probable glycerol kinase deficiency.

The National Cholesterol Educational Program Adult Treatment Panel's third report define borderline-high, high, and very high triglycerides as serum levels of 150-199 mg/dL, 200-499 mg/dL, and ≥500 mg/dL, respectively. Hypertriglyceridemia (HTG) is generally very responsive to both therapeutic lifestyle changes (TLC), and drug therapy, with niacin, omega-3 fatty acids, fibrates, and statins, each reducing levels by ~10-50%. This paper presents two cases of patients who were aggressively treated for significant HTG with little response to therapy.

The high-dose rosuvastatin once weekly study (the HD-ROWS).

Background: Alternative dosing is often used clinically to address common barriers with statin therapy, such as intolerance and cost. Previous findings have demonstrated significant and clinically similar reductions in low-density lipoprotein (LDL) cholesterol to daily dosing, when comparing similar total weekly doses.

Objective: To determine whether rosuvastatin 80 mg once weekly produced comparable lipid and high-sensitivity C-reactive protein (hsCRP) changes to atorvastatin 10 mg daily, when measured at key points after last dose.

Modified-policosanol does not reduce plasma lipoproteins in hyperlipidemic patients when used alone or in combination with statin therapy.

Policosanol is a poorly absorbed nutritional supplement used primarily for cholesterol management. Findings from previous trials evaluating the effects of policosanol are mixed with early data reporting positive lipid effects while more recent studies indicate negligible efficacy. We hypothesized that re-formulating policosanol would result in an improvement in major lipoproteins and possibly provide some explanation for previously conflicting trial data.

Important considerations for treatment with dietary supplement versus prescription niacin products.

Niacin is a water-soluble B vitamin (B3) known to have favorable effects on multiple lipid parameters, including raising high-density lipoprotein cholesterol (HDL-C) levels and lowering triglycerides (TGs), lipoprotein(a), and low-density lipoprotein cholesterol (LDL-C). Although LDL-C remains the primary target of lipid-altering therapy, current guidelines emphasize HDL-C and other modifiable lipid factors as key secondary targets. Thus, niacin is considered an important therapeutic option to help reduce the risk of cardiovascular disease in patients with mixed dyslipidemia who, in addition to high LDL-C, have elevated TGs and low HDL-C.
