Other causes of heart failure include:
- pregnancy: You may develop high blood pressure during pregnancy. This condition is called preeclampsia.
- birth defect: Part of your heart may not have developed correctly. This is known as congenital heart disease.
- infection: Your valves and/or heart muscle may be damaged by either a viral or bacterial infection.
- lung disease or diabetes: Both of these diseases put extra strain on your heart. The extra work can cause your heart muscle to weaken.
- alcohol, illegal drugs, chemotherapy or other toxins: These can cause the heart muscle permanent damage.
- morbid obesity: Being very overweight may cause heart failure due to the extra work the heart has to perform.
