NEW YORK (Sept. 10, 2007) -- For high-blood-pressure patients, preventing or reducing enlarged heart (left ventricular hypertrophy or LVH) reduces risk of heart failure. The study is published in the Sept. 4 Annals of Internal Medicine and led by physician-scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center in New York City.

An estimated 20 percent of all high-blood-pressure patients, or 12 million Americans, have LVH and are at increased risk of developing heart failure.

While the direct relationship between levels of LVH in patients with high blood pressure and risk of cardiac complications -- including death, heart attack, stroke and atrial fibrillation -- has previously been demonstrated by NewYork-Presbyterian/Weill Cornell researchers (JAMA, 2004 and 2006), the new study is the first to demonstrate that prevention or regression of LVH reduces risk of being hospitalized for heart failure -- and that this relationship exists independent of therapy type and the benefits of blood pressure reduction. The study uses data from the Losartan Intervention for Endpoint Reduction in Hypertension (LIFE) study conducted between 1995 and 2001.

"The message for high-blood-pressure patients is that by preventing or reversing enlarged heart, there is an added benefit, over and above any reduction in blood pressure, of lowering risk for heart failure," says the study's principal investigator, Dr. Peter Okin, director of clinical affairs and professor of medicine in the Greenberg Division of Cardiology at Weill Cornell Medical College and a cardiologist at NewYork-Presbyterian/Weill Cornell.

"And, from a public health perspective, our findings suggest that blood-pressure therapy targeted at regression or prevention of LVH may help to blunt the increasing incidence of heart failure," continues Dr. Okin.

Of the 8,479 high-blood-pressure patients without heart failure followed in the new study, 214 were hospitali
