Heart failure is a condition that occurs when the heart can’t pump out enough blood and oxygen to meet the body’s needs. Deaths from it have been climbing steadily nationwide since 2012, wiping out earlier declines. Rising rates of metabolic disorders like obesity, diabetes and high blood pressure are likely contributing. There are medications to treat one of the two main types of heart failure, but they aren’t used as much as they should be, doctors said. “The treatments that have been proven in trials to work are not getting prescribed to people in a timely way,” said Dr. Janet Wright, the director of the division for heart disease and stroke prevention at the Centers for Disease Control and Prevention.
