Inflammation and heart disease





Inflammation and heart disease

Over the last couple of months there have been papers that reinforce evidence that heart researchers have had for years - that inflammation plays an important role in heart disease.

Over the last couple of months there have been papers that reinforce evidence that heart researchers have had for years - that inflammation plays an important role in heart disease.
.
There are a few lines of evidence. One is that people with immune diseases like rheumatoid arthritis and lupus have a raised risk of heart attacks. It's also known that white blood cells and immunological hormones assist cholesterol damage in arteries.
....
And it's also known that statins - cholesterol-lowering medications - reduce the risk of heart attacks more than you'd expect from their cholesterol reduction, and they have immune effects.
...
Summarising the findings from the three recent papers, they suggest that while cholesterol lowering is still vital, reducing inflammation - the immune reaction in arteries - is important too.
...
In one study of people on statins, the lower the inflammation, the lower the heart attack risk.
...
In another study of people on a statin, the lower the bad form of cholesterol and inflammation, the slower artery blockage progressed.
...
And a third study of markers of inflammation showed an association with the risk of heart disease.
...
Some lifestyle changes may help lower inflammation, like exercise and diet if you don't like fancy medications, but that's yet to be proven conclusively.
