The study found that patients treated with evolocumab had significantly lower rates of cardiovascular events and adverse effects.
A recent study published in the American Journal of Clinical Nutrition found that high levels of blood lipids can prevent vitamin E from reaching body tissues. The research suggests that measuring only blood levels may be misleading and that past methods of estimating tissue levels are flawed.
The study provides high-resolution pictures of two closely related enzymes, lysosomal phospholipase A2 (LPLA2) and lecithin-cholesterol acyltransferase (LCAT), which play crucial roles in metabolizing cholesterol and other lipids. The findings offer new insights into the mechanisms underlying these disorders and suggest potential thera...

The study found that adding ezetimibe resulted in a significant reduction in cardiovascular events, including heart attacks and strokes.
A study in a rural Midwestern community found that the new cholesterol guidelines substantially increased the number of individuals who qualify for a statin. The biggest driver of this increase was that a larger number of older individuals without known heart disease qualified for a statin under the new guidelines.
Two cholesterol management guidelines agree that nearly all patients with chronic kidney disease should receive statins, but 50% of those recommended are not taking them. The study found the Pooled Cohort risk equations to be accurate among people with CKD, indicating a valid tool for estimating heart disease risk.

Evolocumab, a new PCSK9 inhibitor, has been shown to significantly lower LDL cholesterol levels in patients with familial hypercholesterolaemia (FH) by an average of 60% more than placebo. The treatment was well-tolerated and achieved recommended LDL cholesterol targets in over 60% of patients.
A new study found that genomic data can explain around 15% of patients' responses to cholesterol-lowering statins. The research used data from a clinical trial and identified genetic signatures associated with improved or poor responses to the medication.
A new study found that rosuvastatin is more effective in reducing low-density lipoprotein subfractions in prediabetic patients than those with normal glucose levels. The medication led to a greater decrease in small dense lipoproteins, considered particularly harmful.
The report emphasizes the need for a more individualized approach to treating cardiovascular disease, focusing on reducing cholesterol levels to specific targets based on a patient's unique health profile. This approach includes lifestyle changes, non-lipid risk factor management, and medication tailored to the patient's needs.
A University of Kentucky research team has made a surprising discovery about oxidized LDL's role in cholesterol transport. The findings indicate that mildly oxidized LDL may actually prevent increases in cholesterol accumulation in arterial walls, potentially leading to new treatments for heart disease.
Scientists at the University of Ottawa Heart Institute have discovered a connection between elevated PCSK9 levels and acute heart attacks in patients. Elevated PCSK9 levels were found in blood samples from patients who had experienced a heart attack, but not in those who had never had one or had recovered from a previous attack.
A new study found that moderate wine consumption is protective against cardiovascular disease in people who exercise regularly. However, the study did not find any benefits for people with no exercise habits.
A new study suggests rosuvastatin has an initially more favourable effect on glucose levels compared to atorvastatin in type 2 diabetes patients. This makes rosuvastatin a wiser choice, especially for those struggling to control their glucose levels.
Researchers at the University of Warwick discovered that methylglyoxal damages 'good' HDL cholesterol, reducing its protective function against heart disease. Low levels of HDL are linked to increased risk of heart disease, and MG levels can be managed through diet and supplements.
The ODYSSEY COMBO II trial shows that alirocumab, a PCSK9 inhibitor, lowers LDL-C levels significantly more than ezetimibe when added to regular statin therapy. By week 24 and 52, alirocumab achieved 50.6% and 49.5% reductions in LDL-C, respectively.
The ODYSSEY LONG TERM trial demonstrates alirocumab's efficacy in lowering LDL-C and reducing cardiovascular events. The study showed a significant reduction in major cardiovascular events and improved lipid profiles, suggesting a useful addition to statin therapy for high-risk patients.
A study found sex-specific associations between socioeconomic factors and cholesterol levels, with women having higher total cholesterol and LDL-cholesterol levels. Men's cholesterol levels were linked to their occupation, while women's were more closely tied to education level.
A Yale University study found that new national guidelines can accurately prescribe statins to patients at risk for cardiovascular disease. The research shows the new guidelines produce a modest increase in patient treatment, with only 92% of those with heavy plaque being assigned to statin therapy under the new method.
