✓Well SupportedSmoking, hypertension, and hyperbeta-lipoproteinemia are the leading modifiable causes of ASCVD.✓Well SupportedPeople with lipodystrophies experience severe metabolic disease and extraordinary levels of health risk.◐Partially SupportedFat accumulation in visceral areas, within muscle, the pancreas, and pericardial fat, is associated with significant health risks.◐Partially SupportedMetabolic health is a complex risk factor for ASCVD that cannot be easily quantified by a single biomarker.Partially Supported

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

The discovery of individuals with hypo-functioning PCSK9 led to the development of PCSK9 inhibitor drugs.

◐Partially SupportedIndividuals with congenital forms of severe insulin resistance, including lipodystrophy, have extremely high coronary artery disease risk.

◐Partially SupportedSubcutaneous fat storage is the preferred location for excess energy, and exceeding this capacity leads to detrimental fat accumulation elsewhere.

◐Partially SupportedThe location of fat storage, particularly in the abdomen and organs, is a potent predictor of cardiovascular disease and diabetes risk.

◐Partially SupportedIncreasing gluteofemoral fat storage capacity could reduce cardiovascular risk.

◐Partially SupportedGenetic factors predispose individuals to differences in body composition and increase the risk of developing diseases like coronary disease and diabetes.

◐Partially SupportedSubcutaneous fat levels are largely determined by genetics, are relatively uncoupled from metabolic health, and are therefore less important to monitor.

◐Partially SupportedPatients with lipodystrophy have a smaller capacity for fat storage, leading to earlier manifestation of related problems.

◐Partially SupportedThe diagnosis and recognition of lipodystrophy are currently poor.

◐Partially SupportedFamilial partial lipodystrophy (FPLD) is classified into types 1 through 4, with FPLD1 lacking a monogenic cause and being the most common, but there is no agreed-upon diagnostic method.

◐Partially SupportedThe general medical community is largely unaware of lipodystrophy and does not consider leanness and muscularity as potential indicators of a problem.

◐Partially SupportedA high fat mass ratio confers higher risk of coronary disease events than smoking.

◐Partially SupportedA high fat mass ratio, indicating more fat in the upper body, is detrimental and associated with negative changes in lipid biomarkers and coronary disease.

◐Partially SupportedGenetic alleles that confer a higher gluteofemoral fat mass ratio are associated with adverse lipid biomarkers and coronary disease.

◐Partially SupportedBMI is an imperfect measure of cardiovascular risk, although it is useful in large epidemiological studies.

?Limited ResearchThe precise reasons why ectopic fat accumulation leads to metabolic dysfunction are not fully understood.

◐Partially SupportedFamilial hypercholesterolemia and common hypercholesterolemia share similarities, and insights from rare diseases can inform understanding of common conditions.

?Limited ResearchDifferences in metabolic health outcomes between visceral and subcutaneous fat are not well understood.

◐Partially SupportedRemoving fat from the legs and hips has different metabolic consequences compared to removing fat from the abdomen.

◐Partially SupportedCoronary artery disease remains the leading cause of death globally despite advancements in managing risk factors.

◐Partially SupportedClinicians should be vigilant for deviations from 'oval' fat distribution, as lipodystrophy represents an extreme version of broader metabolic issues.

◐Partially SupportedIncreasing subcutaneous fat may paradoxically reduce insulin resistance and improve metabolic health.

◐Partially SupportedTargeted therapies for improving gluteofemoral fat storage or distribution are likely to be developed, potentially starting with lipodystrophy patients.

◐Partially SupportedBody shapes like apple or pear are strongly associated with cardiovascular and metabolic disease risk.

✕Not SupportedCurrent methods for assessing metabolic health, such as BMI, dexa scans, and basic blood tests, provide a low-resolution picture and may not adequately identify individuals at risk.

◐Partially SupportedIndividuals with normal lipids but elevated ApoB and triglycerides, and potentially reduced fat in the legs and increased abdominal fat, face extreme increases in cardiovascular risk independent of traditional risk factors.

◐Partially SupportedFactors contributing to coronary artery disease risk include late intervention, insufficient lipid reduction, inadequate blood pressure management, continued smoking, and poorly understood metabolic health.
