Adults exposed to Dutch famine in utero exhibit abnormal lipid profiles, with significantly higher total cholesterol and LDL cholesterol levels. Maternal malnutrition in the first trimester permanently alters offspring lipid profiles later in life.
Women who repeatedly gain and lose weight, especially if obese, have lower HDL or
Researchers at the University of Pennsylvania School of Medicine are investigating the potential cholesterol-lowering properties of gugulipid, an extract from the mukul myrrh bush. The study, led by Dr. Philippe Szapary, aims to determine whether gugulipid is safe and effective in reducing mild-to-moderately elevated cholesterol levels.
Researchers have discovered two targets for a new generation of cholesterol-lowering drugs that should allow greater precision in managing cholesterol levels. A key compound, LG268, has been shown to completely block the absorption of cholesterol in mice, while also enhancing the production of reverse cholesterol transporters.

The Estrogen Replacement and Atherosclerosis (ERA) trial used cardiac catheterization to measure narrowing in the heart's arteries caused by a buildup of cholesterol.
Younger men with high cholesterol levels face a greater risk of death from coronary heart disease and cardiovascular disease later in life. Lower serum cholesterol levels translated into an estimated greater life expectancy of 6.1 years for men.
A multicenter study published in the American Journal of Cardiology found that adding Benecol spread to a patient's diet can lower LDL-C and total cholesterol levels by 17% and 12%, respectively. The study also showed that the cholesterol-lowering effect of Benecol was evident as early as the second week of treatment.
The Phase III study data demonstrated a median decrease of 38 percent in LDL-C and a mean increase of up to 18.7 percent in HDL-C with Lescol XL. This reduction is clinically meaningful for coronary heart disease patients, who carry an increased risk of cardiovascular events.
A UB study found that obese children are more likely to have high levels of triglycerides and low levels of protective cholesterol, increasing the risk of heart disease later in life. The research, which analyzed data from over 4,000 children, suggests that monitoring body mass index is crucial for early detection of dyslipidemia.
UC Irvine molecular biologists have discovered a key protein interaction that regulates cholesterol levels in cells, which may provide insights into heart disease and stroke prevention. The study found that a regulatory protein called Sp1 recruits a co-regulating protein to activate genes that balance cholesterol levels.

The study, which involved over 300 participants with mildly elevated cholesterol levels, showed no adverse effects from using the fortified margarine.
Researchers found that lower total cholesterol levels require only dietary changes, while higher levels necessitate medication. The combined strategies are effective in reducing cholesterol across all surveyed individuals, regardless of their initial cholesterol levels.
A cholesterol-lowering drug, pravastatin, has been shown to reduce stroke risk by 20% in patients with heart disease or high cholesterol. The study pooled data from three clinical trials involving over 19,700 participants and found a significant reduction in stroke rate, particularly among those with coronary heart disease.
Researchers found that men with low HDL levels had nearly twice the mortality rate as those with higher levels after coronary bypass surgery. High HDL levels also helped clear bad cholesterol from the blood and protected against heart disease.
Research suggests that men with high HDL cholesterol levels after coronary bypass surgery live longer and experience fewer cardiac events. High levels of HDL cholesterol may be more significant than LDL in predicting long-term outcomes for patients undergoing heart surgery.
A new low-fat sterol ester spread can lower LDL cholesterol levels by 5-10% and may reduce the risk of heart attack and stroke. The study found that consuming 1-2 grams of the substance per day had similar cholesterol-lowering effects, making it a promising non-drug option for heart disease prevention.
A new study reveals that a specific gene variant, apoE-4, is linked to an increased risk of heart disease, even in individuals with normal cholesterol levels. The research, conducted on 731 healthy adults, found that those carrying the apoE-4 gene had a higher incidence of coronary events compared to non-carriers.
Elevated cholesterol levels are associated with an increased risk of preeclampsia, a pregnancy complication that can lead to seizures, liver or kidney failure, and premature delivery. Women with high cholesterol before pregnancy are more likely to develop the condition, which affects thousands of women each year.

A study published in Preventive Medicine reveals a significant decline in total cholesterol levels among U.S. adolescents, from 167 mg/dL in 1970 to 160 mg/dL in 1994. This decrease is similar to the drop in cholesterol levels among adults during the same period.
A CSIRO study found that margarines high in polyunsaturated fats and low in trans fatty acids reduce LDL cholesterol by 11-15%, corresponding to a 20-30% fall in heart disease risk. The study also showed that these margarines can produce a greater fall in blood LDL-cholesterol than other types of margarine.

A new study reveals that more than half of children consume excessive amounts of fat, leading to increased risk of cardiovascular disease. The study found that most children exceeded the recommended levels of total fat intake and also had inadequate consumption of desirable monounsaturated fats.
A study found that a gene called apolipoprotein E (apo)E influences blood cholesterol levels and predicts how much those levels are affected by weight gain, smoking, and other lifestyle factors. People with the apoE-2 variant have a beneficial cholesterol profile, but risk factors like smoking and obesity can negate this benefit.
Researchers at Wake Forest University Baptist Medical Center demonstrated a gene-diet interaction that affects cholesterol absorption in humans. The study found that individuals with the apo A-IV-2 gene variant absorbed less cholesterol than those without the variant, particularly on diets high in polyunsaturated fat.
A 12-year study of doctors found that men who ate a diet rich in nuts had a decreased risk of dying from heart disease. In another study, people eating an oat-rich diet had lower blood pressure and reduced cholesterol levels.
