Heart disease rates have been falling for several decades since we’ve learned how to live healthier, but now death rates for those who’ve entered hospitals after severe heart attacks have nearly halved in the last six years, a study shows. "The international team, which studied 44,372 patients in 14 countries, found that death rates fell from 8.4% to 4.5% between 1999 and 2006, mostly thanks to treatments like angioplasty to unblock arteries and anti-clotting drugs."
