The CASCADE Familial Hypercholesterolemia Registry will track therapy, clinical outcomes, and patient-reported outcomes over time aiming to increase familial hypercholesterolemia awareness, promote optimal disease management, and improve outcomes. This study is not recruiting family members of FH patients at this time.

The purpose of this study is to develop a registry of molecularly confirmed Familial Hypercholesterolemia (FH) cases in conjunction with the retrospective FHIRE study (IRB# 18-009654) in order to identify and offer genetic testing to Mayo Clinic patients with suspected FH.

The purpose of this study is to assist patients and clinicians in discussing the potential benefits and side effects of treatment of familial hypercholesterolemia (FH) and to develop a decision aid for use in a clinical setting.

The purpose of the study is to test whether cardio-ankle vascular index, a measure of arterial stiffness that can be obtained in the office setting, is associated with cardiac function and structure as assessed by echocardiography.

The purpose of this study is create a biorepository of patients/families where there is a clustering of a cardiovascular disease (CVD) phenotype with suspected genetic etiology, in order to conduct gene discovery.

The purpose of this study is to enable precision medicine in groups underrepresented in scientific research via the creation of a biobank

The purpose of this study is to identify individuals who may have a condition called Familial Hypercholesterolemia (FH) by using different datasets and methodologies.

This study is being done to better understand how genetic information might improve assessment of heart attack risk.

The eventual goal of this study is to identify genetic and proteomic markers that may influence susceptibility to vascular diseases including peripheral arterial disease, pulmonary hypertension, carotid artery stenosis, arterial aneurysmal disease, fibromuscular dysplasia, congenital heart disease and other less common diseases that affect the blood vessels.
