Researchers found a link between high LDL cholesterol and early-onset Alzheimer's disease. The results could help doctors understand how the disease develops and what the possible causes are, including genetic variation.
Lowering low-density lipoprotein (LDL) cholesterol reduces the risk of heart attacks and stroke, with an ideal value below 100 milligrams per deciliter (mg/dL). But can it be too low? A new study finds that women who have levels of LDL cholesterol 70 mg/dL or lower may be more than twice as likely to have a hemorrhagic stroke than women with LDL cholesterol levels from 100 to 130 mg/dL.
Diets that replaced red meat with healthy plant proteins led to decreases in risk factors for cardiovascular disease (CVD), according to a new study. The study is the first meta-analysis of randomized controlled trials examining the health effects of red meat by substituting it for other specific types of foods.
Patients with lupus are at increased risk of heart disease. Exposing endothelial cells -- known to protect against heart disease, in part by producing nitric oxide -- to the serum of patients with lupus decreased nitric oxide production. Administering L-sepiapterin restored that production.
In a landmark study, scientists discovered what makes white blood cell counts spike in individuals who have high cholesterol, possibly leading to new therapies for heart disease. They looked at hypercholesterolemia, which is the type of high cholesterol that causes very high levels of LDL -- the so-called 'bad' cholesterol -- to circulate in the blood. They identified a new regulatory mechanism in zebrafish models responsible for this increase.
