Key takeaway
The Framingham Heart Study followed 5,881 adults, average age 55, for 14 years on average. After accounting for other risk factors, each extra BMI point went with a 5% higher risk of heart failure in men and 7% in women. People with obesity had about twice the risk of people with a normal BMI.
