Congestive heart failure, or CHF, is a condition in which the heart cannot pump enough blood to body organs. This causes a build up of fluid in the lungs and other organs. CHF may be caused by chronic hypertension, coronary artery disease, heart attack, heart valve disease, congenital heart defects and heart muscle disease. Caffeine can aggravate CHF and other heart problems.
