| "TUESDAY, May 1 (HealthDay News) -- As more medical centers have begun adopting new heart disease treatment guidelines, the rates of heart failure and death have been dropping, new research suggests." "More recent guidelines have emphasized the need for more aggressive use of proven medications, such as aspirin and beta blockers, as well as the expedient use of angioplasty to open up blocked arteries. The good news is a study in the May 2 issue of the " " that found that as hospitals start implementing these guidelines, the rates of new heart failure and mortality rates go down." ""By applying the benefits of existing clinical trials -- as synthesized in national and international guidelines -- huge benefits for patients can be gained, and it is possible to prevent deaths and heart failure," said study author Dr. Keith A. A. Fox, the British Heart Foundation professor of cardiology at the University of Edinburgh in Scotland." "Each year, almost 8 million Americans will have a heart attack and another 5 million will have heart failure, according to the American Heart Association. A heart attack occurs when blood flow to the heart is blocked, usually by a blood clot. Heart failure occurs when the heart becomes so damaged that it can no longer pump blood efficiently." "Numerous randomized clinical trials have been conducted, and more and more evidence is available to doctors regarding treatment of heart disease. As a result of all these trials, many organizations, such as the American Heart Association, the American College of Cardiology and the European Society of Cardiology, have issued new treatment guidelines, according to Fox." "New guidelines call for more aggressive use of medications, such as oral anti-clotting drugs like aspirin, beta blockers, angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs), and statins. Guidelines also recommend that when appropriate, angioplasty be performed quickly." "To assess the impact that implementation of these new guidelines has had on patient care, Fox and his colleagues gathered data on almost 45,000 people treated at 113 hospitals in 14 different countries. The researchers assessed in-hospital and six months post-discharge outcomes." "Fox said that due to implementation of new guidelines, "survival was markedly improved, and, for the first time in any study, we have shown a marked reduction in the development of new heart failure." " "Overall, he said, "deaths in heart attack declined from 8.4 percent to 4.6 percent, new heart failure from 19.5 percent to 11 percent, and new heart attacks from 4.8
