The findings come in an analysis of five major studies involving nearly 50,000 adults aged 45 and older who were followed for up to 50 years.
Here's a reality check for health-conscious baby boomers: Even among
those in good shape, at least 1 in 3 will eventually develop heart problems or
have a stroke. The upside is that that will happen about seven years later than
for their less healthy peers.
The findings come in an analysis of five major studies involving nearly
50,000 adults aged 45 and older who were followed for up to 50 years.
The best odds are in the healthiest adults — those who don't smoke, have
diabetes, high blood pressure or high cholesterol. Still, among 55-year-olds in
that category, about a third can expect to develop heart or other
cardiovascular problems as they age.
Dr. Vincent Bufalino, a Chicago area cardiologist and spokesman for the
American Heart Association, said the study is "a wake-up call that this
disease is very prevalent in the United States and even if you're doing a good
job, you're not immune." The researchers estimated risks older people face
for developing these ailments in their lifetime, or by their 80s or 90s. They
also estimated how many years they'll live free of heart disease and related
problems, depending on the most common risk factors.
Pooling follow-up data from the five analyzed studies, the researchers
found that the healthiest 45-year-olds lived up to 14 years longer free of
heart ailments than those with at least two risk factors. The healthiest
55-year-olds lived up to about seven years longer than their less healthy
peers. The study was published online Monday (Nov. 5) in the Journal of the
American Medical Association and released in connection with the American Heart
Association conference meeting in Los Angeles. The National Heart, Lung and
Blood Institute paid for the research. The authors estimated higher lifetime
risks than previous studies, but their analysis involved a broader range of
ailments, including heart failure and strokes.
While prevalence of heart disease and related deaths have declined
nationwide in recent years, more than 82 million Americans — roughly one-third
— have some form of cardiovascular disease, according to the American Heart
Association. Most people in the analysis had high blood pressure or at least
one of the other risk factors. The results shouldn't be discouraging, said lead
author Dr. John Wilkins, an assistant professor of preventive medicine and
cardiology at Northwestern University's medical school in Chicago. Maintaining
an optimal lifestyle, by eating sensibly and staying active, is still the best
way to live a long, healthy life, he said.
Heart disease remains the nation's leading cause of death, and the study
reinforces the idea that "cardiovascular disease is part of the aging
process," said Cleveland Clinic heart specialist Dr. David Frid, who was
not involved in the research. Bodies wear out, "and ultimately, just
exposure to living is going to cause people to develop some of these underlying
problems," Frid said.
