The role of nutrition-related clinical trials in informing dietary recommendations for health and treatment of diseases.

Dietary guidance is based on a robust evidence base that includes high-quality clinical trials, of which some have been designed to establish causal relationships between dietary interventions and ASCVD risk reduction. However, the complexity associated with conducting these trials has resulted in criticism of nutrition and dietary recommendations because the strength and quality of evidence falls short of that for some pharmaceutical interventions. In this paper, we aim to promote greater awareness of the nutrition-related clinical trials that have been conducted showing ASCVD benefits and how this evidence has contributed to dietary recommendations.

JCL roundtable: Evolution of preventive cardiology and clinical lipidology.

It's a privilege to discuss preventive cardiology with 3 of the foremost U.S. leaders in this growing subspecialty.

Contemporary Homozygous Familial Hypercholesterolemia in the United States: Insights From the CASCADE FH Registry.

Background Homozygous familial hypercholesterolemia (HoFH) is a rare, treatment-resistant disorder characterized by early-onset atherosclerotic and aortic valvular cardiovascular disease if left untreated. Contemporary information on HoFH in the United States is lacking, and the extent of underdiagnosis and undertreatment is uncertain. Methods and Results Data were analyzed from 67 children and adults with clinically diagnosed HoFH from the CASCADE (Cascade Screening for Awareness and Detection) FH Registry.

JCL Roundtable: From Gen Med to Clinical Lipidology.

The prevalence of lipid-related risk for atherosclerotic cardiovascular disease surpasses half the population as individuals age, and thus generalists and primary care providers manage by far the bulk of treatment of lipid disorders. It should come as no surprise that many individuals who practice clinical lipidology, focusing on the care of patients with resistant or perplexing lipid disorders, come from a background of general or primary care medicine. Among 429 providers responding to a survey of National Lipid Association (NLA) members in 2010, 50% were internal medicine or family medicine practitioners, 32% cardiologists, 11% endocrinologists, and 7% with a variety of other specialty training.

JCL Roundtable: Lipidology and Women's Health.

In this JCL Roundtable, we bring together three experts to discuss women's cardiovascular health throughout the lifespan, viewed from the standpoint of clinical lipidology. Overall, heart disease leads to one out of every 3 deaths of American women, but unfortunately patient awareness of cardiovascular risk actually has declined since 2009. Younger women are not exempt, since their risk can be increased by smoking, birth control, adverse lifestyle and diet, and genetic disorders.

Assessment and management of statin-associated muscle symptoms (SAMS): A clinical perspective from the National Lipid Association.

Statin-associated muscle symptoms (SAMS) are the most common form of statin intolerance and are associated with increased risk of cardiovascular events that manifest from statin underutilization and discontinuation. The reported frequencies of SAMS are divergent in the literature. The writing group estimates the prevalence of SAMS, namely all muscle symptoms temporally related to statin use but without regard to causality, to be about 10% (range 5% to 25%), and the prevalence of pharmacological SAMS, specifically muscle symptoms resulting from pharmacological properties of the statin, to be about 1-2% (range 0.

JCL Roundtable. Obesity, Diabetes, and Liver Disease in Relation to Cardiovascular Risk.

Metabolic risk for cardiovascular and other systems includes much more than just LDL cholesterol. This JCL Roundtable brings together 3 experts to address new opportunities to reduce the risks posed by obesity, diabetes, and fatty liver disease. Successful nutritional approaches to weight loss are diverse and need to be matched with individual preferences.

JCL Roundtable. The lipidology team.

Clinical lipidology practice works best when implemented by a health care team. The 3 discussants for this JCL Roundtable are National Lipid Association leaders representing essential areas on the team - Registered Dietitian Nutritionist, Advanced Practice Provider, and Clinical Pharmacist. The team approach has been shown more effective than traditional sole provider management for controlling chronic asymptomatic conditions like hypercholesterolemia.

JCL Roundtable. Making prevention a priority.

Clinical lipidology belongs par excellence to the preventive mode of medical practice. This Roundtable brings two long-time advocates of cardiometabolic prevention and a newly minted preventive cardiologist into a discussion that expands their recent JCL editorial on this topic. Atherosclerosis is a single disease process that leads to approximately 25% of deaths in economically advanced nations and a growing fraction of mortality and morbidity in nations with developing and emerging economies.

JCL Roundtable: Global Think Tank on Lipoprotein(a).

Lipoprotein(a) operates in causal pathways to promote atherosclerosis, arterial thrombosis, and aortic stenosis. It has been associated with rare cases of nonatherosclerotic arterial thrombotic stroke at any age. Inherited variation of lipoprotein(a) levels substantially increases cardiovascular risk in 20% of people worldwide.
