High BMI and reduced physical activity are both known risk factors for heart failure. A recent study investigates the impact of these factors on a specific subtype: heart failure with preserved ejection fraction.
When the heart is no longer able to pump enough blood to meet the body's oxygen demands, it is referred to as heart failure - a chronic and progressive condition.
An estimated 5.7 million adults in the United States have heart failure. In fact, heart failure was responsible for 1 in 9 deaths in the U.S. in 2009.
There are a number of subtypes of heart failure, one of which is called heart failure with preserved ejection fraction (HFpEF). This form of the condition is characterized by a stiffening of the left ventricle and a reduction in its ability to relax between contractions.
