If you've already had COVID and then get your first vaccine, your body might dial down certain blood clotting and inflammation proteins, which could mean your immune system is responding differently...
Getting your first COVID vaccine when you've never had the virus seems to turn on key parts of your immune system that help fight off infections, especially by boosting certain immune cells and...
Getting the COVID vaccine barely changes the proteins in your blood, but actually catching the virus causes big shifts in those same proteins.
Getting COVID-19 causes long-lasting changes in the body's immune system proteins, revealing new clues about how our bodies react to the virus.
Kids with certain PCSK9 gene changes keep having lower 'bad' cholesterol as they grow up—this finding is from the abstract summary - full study details were not available
African-American kids with certain PCSK9 gene changes (Y142X or C679X) have lower 'bad' cholesterol from a young age—this finding is from the abstract summary - full study details were not available
White kids who have a certain genetic change (R46L) in the PCSK9 gene tend to have lower 'bad' cholesterol levels from a young age—this finding is from the abstract summary - full study details were...
For people with heart disease, even when doctors start with a middle-strength cholesterol pill and adjust based on blood tests, more than half still end up needing the strongest dose to get their...
For people with heart disease, adjusting statin doses to hit a cholesterol target leads to about the same average 'bad cholesterol' level over 3 years as always using the strongest dose. This finding...
For people with heart disease, aiming for a specific 'bad cholesterol' level using adjustable statin doses works just as well over 3 years as starting with the strongest statin dose, when it comes to...
For people who can’t take statins because of muscle pain, evolocumab alone cuts bad cholesterol by over half and helps many reach safe levels, while another drug (ezetimibe) doesn’t work nearly as...
Evolocumab is very safe—even when used for over 8 years and when cholesterol drops to extremely low levels, it doesn’t cause serious side effects, diabetes, or memory problems. The only common issue...
The lower the bad cholesterol gets with evolocumab, the lower the risk of heart problems—even when cholesterol drops to very low levels, there’s still added protection, and no ‘too low’ point has...
For people who already have heart disease, adding evolocumab to their cholesterol medicine lowers their risk of heart attack, stroke, or dying from heart problems by about 1 in 5, and the protection...
When people with heart disease add a drug called evolocumab to their cholesterol medicine (statin), their bad cholesterol drops by about 60% quickly and stays low for years, helping most of them...
Taking stronger treatments to lower bad cholesterol seems to cut the risk of heart attacks, strokes, and other serious heart problems — even if your cholesterol isn’t that high to begin with.
If your 'bad' cholesterol is 100 or higher, lowering it more aggressively helps prevent heart-related deaths. But if it's already below 100, lowering it even more doesn't seem to help much — there...
If you have high 'bad' cholesterol, lowering it more aggressively can help you live longer, especially if your levels are really high to begin with. Doctors should decide how hard to treat based on...
People in Saudi Arabia with a rare cholesterol condition don’t seem to lower their bad cholesterol as much with a certain drug as other people did in past studies — and it might be because of their...
For people in Saudi Arabia with a rare inherited form of very high cholesterol, taking a drug called Evolocumab once a month didn’t seem to lower their bad cholesterol much — the drop was small and...
In a group of 37 people in Saudi Arabia with a rare cholesterol condition, the most common gene change was in the LDL receptor, which likely breaks how the body clears bad cholesterol — and this...
For people in Saudi Arabia with a rare genetic form of very high cholesterol, taking a drug called evolocumab every two weeks seems to lower their bad cholesterol a little bit — not a huge drop, but...
For people with heart disease who are on cholesterol-lowering drugs, adding a drug called evolocumab doesn’t raise their risk of serious side effects — including diabetes or memory problems —...
Even if someone with heart disease is already taking cholesterol-lowering drugs and their cholesterol is pretty low, adding a drug called evolocumab can still help protect their heart.
