New Study Highlights Surprising Link Between Heart Attacks and Inflammation

Anti-inflammatory drug may also reduce deaths from cancer, but more research is needed

Study found lower cancer death rates in people on the drug.

For the first time, a drug has helped prevent heart attacks by curbing inflammation, a new and very different approach than lowering cholesterol, the focus for many years.

A study found that people on the drug also had surprisingly lower cancer death rates, especially from lung cancer. An anti-tumor effect is an exciting possibility, but it needs much more study because the heart experiment wasn't intended to test that.



Doctors say the results on the drug, canakinumab, open a new frontier. Many heart attacks occur in people whose cholesterol is normal and whose main risk is chronic inflammation that can lead to clogged arteries.

"We suddenly know we can address the inflammation itself, the same way we learned almost 25 years ago that we could address cholesterol. It's very exciting," said the study's leader, Paul Ridker, M.D., of Brigham and Women's Hospital in Boston.

Results were published Sunday by the New England Journal of Medicine and the Lancet, and presented at the European Society of Cardiology conference in Barcelona, Spain. The drug's maker, Novartis, sponsored the study, and Ridker consults for the company.

One-quarter of people who suffer a heart attack will have another one within five years, and inflammation is a culprit in half of those cases. Inflammation happens after a joint is injured and swells, and similar chemical responses can occur over time throughout the body with unhealthy habits. That chronic, unseen inflammation can damage arteries and set the stage for clots.
