The study highlights a significant unmet need for improving equity in cardiovascular risk reduction.
Children with homozygous familial hypercholesterolemia are diagnosed earlier and have higher untreated LDL-C levels than adults, while those not identified early miss out on decades of life-saving treatment. This study emphasizes the need for universal screening to identify children with HoFH or heterozygous familial hypercholesterolemia.
A new analysis from the Family Heart Foundation shows that only 31.3% of individuals with familial hypercholesterolemia (FH) in its database had been diagnosed as of June 2020. This represents a significant increase since 2016, but highlights the ongoing challenge of diagnosing and managing the condition.
A study estimates that more than 1 million U.S. adults carry a gene for familial hypercholesterolemia, a genetic disorder causing high cholesterol and potentially leading to premature heart attack or death. Genetic testing may help identify those at risk, but its affordability is a concern.
A study of 35 low- and middle-income countries found that less than one-third of individuals with high cholesterol received treatment. This highlights the inadequate care for hypercholesterolemia in these regions, a major risk factor for cardiovascular disease.
A new canine mutant model mimics human cerebrovascular disease by exhibiting severe arteriosclerosis, thrombosis, and stroke. The ApoE knockout dogs show extensive and severe arteriosclerosis plaques and arterial stenosis, consistent with human cerebral arteries and coronary arteries.
Researchers at Queen Mary University of London tested an algorithm on 700,000 patient records in east London to identify Familial Hypercholesterolemia, a leading cause of heart attacks in young people. The 'FAMCAT' algorithm analyzes GP data and family history to predict who may be at risk.
New data from the CASCADE FH Registry highlights gaps in care for children with familial hypercholesterolemia. Children are typically diagnosed at age 9, seven years after cholesterol screening guidelines recommend it. Early treatment intervention can prevent cardiovascular disease.
A phase 2 study found that evinacumab reduced LDL cholesterol by 50% in patients with severe hypercholesterolemia resistant to standard treatments. The therapy works through a different mechanism than existing drugs and shows promise for treating refractory hypercholesterolemia.
A new study published in BMJ Evidence-Based Medicine suggests that people with familial hypercholesterolemia should eliminate carbs and focus on a heart-healthy diet low in sugar. The research finds no evidence to support the long-held recommendation to minimize saturated fat intake.
A global coalition is calling for early screening and coordinated lifetime care for familial hypercholesterolemia, a condition affecting 34 million people worldwide. The initiative aims to prevent premature cardiovascular disease and save lives by leveraging scientific data, novel therapies, and technological advances.
A new machine learning algorithm identified individuals with probable familial hypercholesterolemia (FH) for the first time at a national scale, reducing the number of people needed to be screened. The FIND FH model performed comparably well on diverse healthcare data and has been implemented in several US healthcare systems.
A recent study found that lowering cholesterol with statins does not decrease the activation of immune cells in patients with high cholesterol levels. This 'trained immunity' allows immune cells to 'remember' previous exposures and maintain hyperactivity despite cholesterol reduction.
Researchers analyzed data from 1.2 million donors to determine if blood donation programs could detect familial hypercholesterolemia, a genetic disorder causing high cholesterol and premature coronary artery disease. The study found that about 1 in every 339 donors met the criteria for the condition.
