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 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.
