A new study found that people with short variants of the APOB gene region have significantly lower total and low-density lipoprotein cholesterol levels in their blood. This association may contribute to a protective role of these variants in younger adults, while being detrimental to longevity in older individuals.
Scientists propose that alterations in cholesterol and ceramide contribute to neurodegenerative cascade destroying neurons in Alzheimer's disease. Oxidative stress triggered by beta amyloid peptide leads to ceramide accumulation, causing nerve cell death.

After six weeks, participants on the moderate-fat diet had a healthier heart profile, with reduced cardiovascular risk and improved lipid profiles.
Dialysis patients with inflammation or malnutrition have lower cholesterol levels than those without. Higher cholesterol is associated with lower mortality among patients without these conditions, but not among those with them.
A recent study found that only 37% of adults with diagnosed diabetes are achieving the American Diabetes Association's goal for blood glucose control, while nearly half have high cholesterol and high blood pressure. The lack of lifestyle changes, such as exercise and weight loss, is a major contributor to this issue.

A UK multi-centre randomised trial found that statins reduce the risk of heart attacks, strokes or revascularisation operations by about a third in diabetic patients, irrespective of their cholesterol levels. This could prevent at least 10,000 heart attacks, strokes and revascularisation operations each year worldwide.
Researchers analyzed lipid levels of HIV patients before and during HAART and found that average total and LDL cholesterol levels remained stable over three years.

Duke University researchers found that exercise reduces potentially harmful cholesterol levels in the blood. The extent of this benefit depends on exercise amount and intensity, as well as gender. After a five-year trial, they discovered that high-intensity exercise led to sustained benefits in HDL cholesterol for both men and women.
Greek Orthodox Christians who followed a fasting regimen experienced lower cholesterol and LDL levels in their blood. Regular fasting may provide long-term protection against heart disease by increasing the HDL/LDL ratio.

The STELLAR study found CRESTOR 10-40mg reduced LDL-C by 46 to 55 percent, while raising HDL-C by 7.6 to 9.6 percent compared to other statins. The study was part of AstraZeneca's GALAXY Program and included over 19,000 patients from 23 countries.
A recent study found that high levels of Lp-PLA2 and CRP are associated with an increased risk of coronary heart disease, even in patients with 'normal' LDL cholesterol levels. The study used the PLAC test to measure Lp-PLA2 levels in participants and found significant associations between Lp-PLA2, hs-CRP, and CHD incidence.
A study published in MERCURY I showed that CRESTOR 10mg effectively lowered LDL-C levels and enabled over eight out of ten patients to achieve their LDL-C goals. The medication demonstrated superior efficacy compared to atorvastatin, making it a valuable treatment option for managing high cholesterol and reducing cardiovascular risk.

A study by the American Heart Association suggests that women approaching menopause should take steps to lower their heart disease risk. Researchers analyzed data from over 1,300 perimenopausal women and found that many would become eligible for cholesterol-lowering therapy after age 55 if current risk factors are not modified.
Roth's discovery led to the development of Lipitor, which has logged more than 36-million patient years of experience and involved over 400 clinical trials. His innovative approach to statin structure resulted in a simpler molecule with equal efficacy.
Recent studies suggest apolipoprotein B is a superior marker for predicting cardiovascular disease risk compared to total cholesterol or LDL cholesterol. The ratio of apolipoprotein B to apolipoprotein A-1 is also more effective in assessing cardiovascular risk than the traditional LDL/HDL ratio.
