Exercising more, sitting less reduces heart failure risk in men

Summary:
Increased sedentary time may be linked to greater heart failure risk, according to first study its kind. Being very physically active and less sedentary reduces heart failure risk. High sedentary levels increase heart failure risk regardless of physical activity levels.

Sitting for long periods increases heart failure risk in men, even for those who exercise regularly, according to new research published in the American Heart Association journal Circulation: Heart Failure.

Preventing heart failure, researchers found, requires a two-part behavioral approach: high levels of physical activity plus low levels of sedentary time. The study is the first to examine the link between heart failure risk and sedentary time, said Deborah Rohm Young, Ph.D., lead researcher and a senior scientist at Kaiser Permanente in Pasadena, Calif.

"Be more active and sit less. That's the message here," Young said.

Researchers followed a racially diverse group of 84,170 men ages 45 to 69 without heart failure. Exercise levels were calculated in METs, or metabolic equivalent of task, a measure of the body's energy use. Sedentary levels were measured in hours. After an average of nearly eight years of follow-up, researchers found:

  • Men with low levels of physical activity were 52 percent more likely to develop heart failure than men with high physical activity levels, even after adjusting for differences in sedentary time.
  • Outside of work, men who spent five or more hours a day sitting were 34 percent more likely to develop heart failure than men who spent no more than two hours a day sitting, regardless of how much they exercised.
  • Heart failure risk more than doubled in men who sat for at least five hours a day and got little exercise compared to men who were very physically active and sat for two hours or less a day.

Study limitations included: Since no women were studied the results may not apply to them; results were self-reported, which could mean physical activity was over reported; results were based only on time outside of work and can't be applied to overall sedentary activity; and participants were members of comprehensive health plans, so results may not apply to men lacking health insurance.

The study supports the American Heart Association recommendation that people get at least 150 minutes a week of moderate-intensity aerobic activity to reduce their risk for heart failure and other cardiovascular diseases, Young said.

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
