Heart failure affects about 5.7 million Americans. Heart failure is a chronic, progressive condition in which the heart muscle is unable to pump enough blood through the heart to meet the body's needs for blood and oxygen. Basically, the heart can't keep up with its workload.
At age 40, a person’s lifetime risk of developing heart failure is already one in five. In a new study, people who had one of a certain group of healthy lifestyle behaviors decreased their heart failure risk, and each additional healthy behavior further decreased their risk.
What are these healthy lifestyle choices? If you don’t smoke, aren’t overweight, get regular physical activity and eat vegetables, you can significantly reduce your risk for heart failure, according to research reported in Circulation: Heart Failure, an American Heart Association journal.
“Any steps you take to stay healthy can reduce your risk of heart failure,” said Gang Hu, MD, PhD, lead author of the study and director of the Chronic Disease Epidemiology Laboratory at the Pennington Biomedical Research Center in Baton Rouge, LA. “Hypothetically, about half of new heart failure cases occurring in this population could have been prevented if everyone engaged in at least three healthy lifestyle behaviors.”
Previous research showed an association between healthy lifestyle behaviors and lower risk of heart failure in men. The new study is the first to find a similar connection in women.
Researchers followed 18,346 men and 19,729 women from Finland, ages 25 to 74 years old. During a median follow-up of 14.1 years, 638 men and 445 women developed heart failure. Participants were classified by their BMI: normal weight (less than 25); overweight (25-29.9) and obese (greater than 30).
After adjusting for heart failure risk factors, such as high blood pressure, diabetes and a past heart attack, researchers found:
Furthermore, the more healthy lifestyle behaviors a person engaged in, the greater the decline in risk. Engaging in all four healthy lifestyle behaviors decreased the risk for heart failure by 70 percent in men and 81 percent in women, compared to 32 percent in men and 47 percent in women who engaged in only one healthy behavior.
Unfortunately, many people remain unaware of the link between unhealthy lifestyle behaviors and heart failure risk, researchers said. “Healthcare workers should discuss healthy lifestyle habits with their patients and stress that they can do more,” says Dr. Hu.
But don’t wait for your doctor to bring up the topic of healthy lifestyles: Be proactive. If you still smoke, ask about quitting smoking programs and possibly medications to finally kick the habit. Get advice on starting a weight-loss diet supplemented by exercise, even walking in your neighborhood. And make the commitment to eating a variety of vegetables every week—to get the most nutrients, choose a rainbow of colors.
