What it means
The NHLBI estimates, citing the CDC, that more than 6 million US adults have heart failure. It is usually caused by other conditions that strain or damage the heart, such as coronary artery disease, high blood pressure, diabetes or heart muscle disease.
Symptoms can include shortness of breath, tiredness, swelling in the legs or belly and trouble lying flat. Doctors often describe it by ejection fraction, the share of blood pumped out with each beat. In heart failure with preserved ejection fraction, the heart pumps normally but is stiff and does not fill well. This type is closely linked with obesity.
Clinical trials have studied GLP-1 medicines in people with obesity and this preserved-ejection-fraction type, with results reported on symptoms and physical function. Ask a cardiologist how that research applies to you.
Sudden weight gain of a few pounds in a day or two can mean fluid buildup in heart failure and should be reported promptly.
Why it matters
Obesity is a major driver of one common type of heart failure, an area of active GLP-1 research.
