I'll be what I am, a sedentary man.

January 8, 2014 Scientists have engineered a natural adhesive that can patch a hole in a pig's heart. The experimental glue is nontoxic, dissolves in the body and withstands high pressure inside a beating heart. But there's still a long way to go before the superglue could replace sutures in the operating room or on the battlefield.

Some people with only slightly elevated blood pressure might be able to relax a bit, if they're doctors go along new treatment guidelines.
December 19, 2013 Many people over 60 won't have to work so hard to lower their blood pressure, if doctors adhere to guidelines for treatment. That's because there's a lack of proof that people with moderately high blood pressure can reduce their risk of heart attacks and strokes by trying to lower it substantially with drugs.
Gym members warm up on treadmills at Downsize Fitness in Addison, Texas. Membership at the gym is limited to people who have a high body mass index.
December 3, 2013 The proposition that some extra weight may not be a health worry has sparked a heated medical debate. Some studies have found that a little extra fat might have benefits. A new analysis suggests that for almost all people excess weight increases the risk of death and disease.
Regular nut consumers had about a 20 percent reduction in all-cause mortality, including lower death rates from heart disease and cancer, a study found.
November 21, 2013 Men and women who were regularly munching on peanuts or tree nuts in their 30s and 40s were significantly more likely to reach their 70s, a study found. Researchers say they aren't sure why nuts promote longevity, but they think it has to do with how they affect metabolism and satiety.

November 18, 2013 Updated just last week by the American Heart Association and the American College of Cardiology, the new guidelines are based on old data, some heart doctors say, and may overestimate the real risk of heart attack and stroke. That could result in overtreatment with cholesterol-lowering drugs.

November 15, 2013 Despite decades of effort, doctors have made almost no progress in reducing the number of people with uncontrolled high blood pressure. It's time to take a much broader approach, an advisory says, with insurers, pharmacists and the community all involved in making it easier for patients to get help.

November 12, 2013 For decades, knowing your cholesterol number was the first step in preventing heart disease and stroke. Heart specialists would shift away from specific cholesterol targets under new guidelines. A risk-based approach tailored to each patient would become the new norm.
Just knowing that someone is obese doesn't mean they would benefit from bariatric surgery, doctors say.
November 4, 2013 Three years after bariatic surgery, most people experienced health improvements. Yet some people benefited much more than others. Figuring out those differences would help doctors and patients understand who should have surgery and who should avoid it.
Spiffing up the garden may also make your cardiovascular risk profile look better, too.
October 29, 2013 Older people who are active every day appear to lower their risk of heart disease and death by almost a third, even if they're not doing the kind of exercise that breaks a sweat. Gardening and puttering around the house qualify. And don't overlook berry-picking, a popular pastime in Sweden, where the study was done.

October 9, 2013 Doctors know who's had a stroke, but they often know a lot less about those people's quality of life afterward. A study of the long-term effects finds that even people with very mild strokes report declines in their quality of life. Anxiety about another stroke and the need for ongoing medical care are two factors.
Gaining a few more years of healthy life would be great for individuals, but expensive for Medicare, researchers say.
October 7, 2013 There's the war on cancer and the war on heart disease. But investing in delaying the aging process may have a better payoff, economists say. Adding two years of healthy living to lifespans would result in $7 trillion in benefits over 50 years, an analysis says. But Medicare and Social Security would cost more, too.
