The power of lipid registries for cardiovascular disease prevention

A contemporary snapshot of familial hypercholesterolemia registries

PURPOSE OF REVIEW

Familial hypercholesterolemia (FH) registries can capture unique data on FH concerning real-world practice, clinic epidemiology, natural history, cascade testing, cardiovascular consequences of late diagnosis, and use of healthcare resources. Such registries are also valuable for identifying and bridging the gaps between guidelines and clinical practice. We reviewed recent findings from the principal FH registries.

RECENT FINDINGS

Most adult patients with heterozygous FH (HeFH) are diagnosed late, undertreated, and do not reach guideline-recommended low density lipoprotein-cholesterol (LDL-C) goals. In children and adolescents with HeFH, detection relies principally on genetic testing and measurement of LDL-C levels. Similarly, the majority of patients with homozygous FH (HoFH) receive sub-optimal cholesterol-lowering treatments and do not attain recommended LDL-C goals, gaps being wider in lower income than higher income countries. In HeFH patients, men have a higher risk of atherosclerotic cardiovascular disease than women.

SUMMARY

The evolving data from FH registries provide real-world evidence for developing implementation strategies to address gaps across the continuum of care of FH worldwide.

LDL-C: The Only Causal Risk Factor for ASCVD. Why Is It Still Overlooked and Underestimated?

PURPOSE OF REVIEW

Low-density lipoprotein cholesterol (LDL-C) is the most important causal risk factor for atherosclerotic cardiovascular disease (ASCVD). This article reviews why LDL-C remains overlooked and underestimated despite numerous studies that have proved its role.

RECENT FINDINGS

Recently published EAS/ESC Guidelines for dyslipidemia and EAS Guidelines for prevention set new targets for LDL-C levels in primary and secondary prevention of ASCVD. These guidelines are based on data from large studies and meta-analyzes that have shown that lower LDL-C also means lower cardiovascular event rates. Real-life experience published in registries worldwide has shown us that the guidelines have not been translated to everyday clinical practice, meaning that a significant number of patients are undertreated and have LDL-C levels well above target. Potential reasons for the abovementioned are poor adherence and education of the patient and physician and health care system related factors. Implementation of the latest version of guidelines will require continuous patient and physicians education, as well as a shared decision-making process between physician and patient.

Hypertriglyceridemia: rationale, design and implementation of the Australian Hypertriglyceridemia Registry

PURPOSE OF REVIEW

Hypertriglyceridemia (HTG) is a risk factor for atherosclerotic cardiovascular disease (ASCVD), aortic stenosis, hepatic steatosis and pancreatitis. We briefly review the aetiology and treatment of HTG and familial chylomicronemia syndrome (FCS), as well as the implementation of a clinical quality registry for improving care, the Australian Hypertriglyceridemia (AUSTRIG) Registry.

RECENT FINDINGS

There is a need to improve the detection of individuals with severe HTG and FCS, who could benefit from more intense and novel treatments to prevent end-organ damage. Patient registries provide valuable data for advancing care of individuals with severe HTG at high risk of acute pancreatitis, steatohepatitis and ASCVD. However, there is a paucity of registries of such patients. We outline the design and implementation of the AUSTRIG Registry.

SUMMARY

Clinical registries can be employed in many ways for improving outcomes for patients with HTG, through the collation and analysis of data for enabling health service planning, clinical trials and audits, and for better informing and empowering registrants.
