| | CHF |
 | | CHF may occur in those who have had a previous heart attack or who have high blood pressure, narrowed arteries to the heart, infections, or congenital heart disease. |
 | | A combination of tests may be used to diagnose the condition, including physical exam, echocardiogram, chest x-ray, and any of several nuclear or CT scans. |
 | | A new test that measures the amount of brain natriuretic peptide (BNP), a hormone found in the left ventricle (the main pumping chamber of the heart), in the blood may also be used to help diagnose and grade the severity of heart failure. |
